    As I sit down at my computer to writethis message, education in Texas is intumult. According toThe Legislative Refer-

    ence Library there are fty-three bills that

    affect the Texas Education Code that have

    been engrossed. I did not know what that

    meant, so I looked it up and this is what I

    found:

    A legislative proposal that has been preparedin a nal orm or its submission to a vote othe law-making body ater it has undergone

    discussion and been approved by the appropri-ate committees. (Wests Encyclopedia of AmericanLaw, published by Tomson Gale)

    Fifty-three: what a daunting number.

    Regardless of what happens in the rest of

    this session, it is safe to say that education

    will be different when we reconvene next

    fall. We do not know what will happen with

    funding, testing, class size, certication, or

    graduation requirements, but there is one

    thing we know for sure: we will have stu-

    dents in our classes that need instruction,

    and it is our job to provide the best possible

    education.

    This issue has some information tohelp you do that. Confusing Language for

    Science and Mathematics Studentsfocuses

    on the differing and, at times, confusing

    language used in math and science and

    how it impacts students learning. Enhanc-

    ing Science Knowledge through Proven In-

    structional Strategies, as the name suggests,

    looks at reading and writing strategies that

    can help students learn. The nal article

    analyzes how participation in local science

    fairs in the North Dallas area impacts thelevels of student interest in scientic elds.

    This has implications for the United States

    competitiveness in a global economy.

    It is my hope that this issue can give

    you something to take your mind off all the

    issues surrounding education in Texas, at

    least for a little while.

    Confusing Language for Science and Mathematics Studentsby Sandra S. West and Sandra . Browning

    English is one of the more difcultlanguages in the world to learn partlybecause it is full of homonyms/homophones

    and synonyms. Words have several different

    meanings depending upon the context of the

    sentence and the audience being addressed.

    Specically for science and mathematics,

    there are discipline-specic homophones

    and homonyms. Bearing this in mind, the

    English language can be a bear for students.

    A Discovery!The issue of confusing language rst

    arose in 2006 when planning a professional

    development session for the project, Mix It

    Up: Correlated Science & Math(CSM). In

    preparation for the rst correlated physics

    and mathematics lessons, the university

    physics instructor noticed that the univer-

    sity mathematics instructor was using the

    word motion differently. When asked what

    motion meant, the mathematics instruc-

    tor said, You know, movement while wav-ing both hands. The science instructor

    said, That is not what we mean by motion

    in physics. We mean moving from point

    A to point B (Author, 2006). The instruc-

    tors then realized that while both science

    and mathematics use the word distance, the

    meaning of the word in science, while

    related to the meaning in mathematics, is

    not the same as in mathematics. This dis-

    covery led to the realization that science and

    mathematics use several of the same words,but many with very different meanings.

    More Discoveries through RichConversations

    Since that discovery in 2006, the Mix

    It Up projects: CSMprojects have contin-

    ued to provide professional development to

    science and mathematics teachers. When

    training grades 5-8 science and mathemat-

    ics teachers to integrate science and math-ematics, the CSMscience and mathematics

    university specialists generally make class-

    room observations as a team. However one

    day, the science specialist conducted an

    observation alone in an eighth grade Algebra

    I class. The mathematics lesson that was

    integrated with science used motion detec-

    tors that had previously been used in the

    eighth grade science class. The students

    used the probes to gather and analyze the

    data on time and distance. The domain andrange of the data set were then determined.

    As the science specialist observed the

    lesson, she wondered why the teacher did

    not teach range before domain since she

    considered rangea less complex concept.

    That night the science specialist was dis-

    cussing and debrieng the algebra lesson

    with the mathematics specialist and asked

    her why the teacher did not teach range

    before domain. The mathematics specialistasked the science specialist to dene range.

    The science specialist said that, in this

    instance, it means the span of numbers

    from the highest number or value to the

    lowest number or value or vice versa.

    For example, considering the

    numbers 1, 2, , 9, the range would be 1 to

    9. The mathematics specialist realized that

    the meaning of range described by the sci-

    ence specialist was not what range meant inthis algebra lesson. In algebra, range typi-

    cally means the set of y-values of a function

    (see Figure 1). In statistics, range generally

    means the difference between the highest

    and lowest value of a set of data (see Figure

    2).

    Confusing Language (contd.)

    If the function f(x) = x+2 is given the values x = {1, 2, 3 ,...} then its range will be {3,4,5, ...}

    In science, range also has several meanings, such as (a) an open region over which

    animals (as livestock) may roam and feed, (b) a series of mountains, (c) the horizontal dis-

    tance to which a projectile can be propelled, (d) the horizontal distance between a weaponand target, (e) a sequence, series, or scale between limits as in a wide rangeof patterns in

    nature, as well as (f) the difference between the least and greatest values of an attribute

    or of the variable of a frequency distribution (Merriam-Webster, n. d.). It is no wonder

    that students are confused. Of course, the word range has a number of meanings in areas

    other than science or mathematics to further confuse students such as in music (distance

    between the lowest and highest notes of an instrument or voice) or the culinary arts (the

    kitchen range). This must be especially confusing for English Language Learner (ELL)

    students. What is a student to do? What is a teacher to do?

    Correlated Science and MathematicsDictionary

    As the CSMteam plans ongoing professional development, confusing words continueto be identied by both instructors and participating grades 5-8 science and mathemat-

    ics teacher teams. Collecting those words and compiling a CSM Identifying Confusing Sci-

    ence and Mathematics Words Dictionaryseemed a logical endeavor to help both teachers

    and students clarify the meaning of terms. Following is a sample of synonyms and homo-

    phones/homonyms that have been identied in the CSMresearch. Sample words that have

    the same or comparable meaning in science and mathematics, called shared vocabulary,

    are also included.

    SynonymsSynonyms are dened as words that have the same or similar meaning. Merriam-

    Webster Dictionary(n.d.) denes them formally as one of two or more words or expressionsof the same language that have the same or nearly the same meaning in some or all senses

    or a word or phrase that by association is held to embody something (n.p.). A sample of

    synonyms from the CSM planning and teaching sessions has been identied (see Figure 3).

    Homophones/Homonyms

    Homophones, or homonyms, are generally thought of as words that sound alike, buthave a different meaning. Merriam-Webster Dictionary (n. d.) denes them as one of two

    or more words spelled and pronounced alike but different in meaning (n. p.). Some of the

    homophones that the CSM team has identied include the following (see Figure 4):

    Confusing Language (contd.)

    Shared VocabularyWhile many words are used differently in mathematics and science, science and

    mathematics also share a common vocabulary (see Figure 5). That is, several words have

    the same or similar denition in both science and mathematics. For example, co-linear

    means lying on the same line in both science and mathematics.

    Recognition of Confusing Language by National Mathematics StandardsThe National Council of Teachers of Mathematics (NCTM) realizes the difculty that

    students have deciphering between everyday or natural language and content specic

    language in mathematics. To address this difculty, NCTM suggests that teachers make a

    conscious effort to help students with confusing words. According to NCTM:

    eachers can help students see that some words that are used in everyday language, such as similar,actor, area, or unction, are used in mathematics with diferent or more-precise meanings. Tis

    observation is the oundation or understanding the concepts o mathematical denitions. It isimportant to give students experiences that help them appreciate the power and precision omathematical language. (NCM, 2000, p. 63)

    This disconnect between natural language and content specic language is especially

    apparent in an algebra class. Driscoll (1999) identies the ability to model real situations

    mathematically as one of the central purposes for algebra. Therefore, the capacity to

    translate from natural language to algebraic expression is crucial. Helping students to

    Confusing Language (contd.)

    Understanding rather than vocabulary shouldbe the main purpose o science teaching.However, unambiguous terminology is alsoimportant in scientic communication and

    ultimatelyor understanding. I teachersintroduce technical terms only as needed toclariy thinking and promote efective commu-nication, then students will gradually build aunctional vocabulary that will survive beyondthe next test. For teachers to concentrate onvocabulary, however, is to detract rom scienceas a process, to put learning or understand-ing in jeopardy, and to risk being misled aboutwhat students have learned.(AAAS, 1989, p. 203)

    We are not suggesting drilling on

    vocabulary denitions. Many recommen-

    dations focus on conceptual understand-

    ing instead of rote memorization of deni-

    tions. Facts and formulas are important in

    mathematics and science, but memorizing

    vocabulary or mathematics tables does little

    to explain or make sense of the concepts

    behind them. Without a deep cognitive

    understanding, knowledge is easily forgot-ten. True understanding involves a much

    deeper approach to learning about concepts,

    and this takes time. Effective teachers teach

    topics in greater depth in order to deepen

    student understanding (Barber, Parizeau,

    & Bergman, 2002). This requires a careful

    review of materials to ensure that important

    knowledge is selected and taught as recom-

    mended by AAAS in Science for All Ameri-

    cans(SFAA) and referred to in (BSL), rather

    than a laundry list of vocabulary words:

    SFAA uses only those technical terms thatscientists believed ought to be part o everyadults vocabulary. Te clear purpose was toree teachers rom spending most o their timeand energy teaching science vocabulary and letthem concentrate on teaching meaningul sci-

    ence. Te pressure to cover the curriculum andtest the students oten leads people teachers,administrators, test makers and parents tobe willing to accept the glib use o technical

    terms as evidence o understanding. Studentswill soon orget all o those technical wordsanyway. Few adults can condently distinguishbetween revolve and rotate, reect and reract,meiosis and mitosis, mass and weight, ordersand amilies, igneous and metamorphic rocks,nimbus and cumulus clouds, mitochrondriaand ribosomes. (AAAS, 1993, p. 312)

    Yet, a problem with emphasizing un-

    necessary academic vocabulary still exists,

    particularly with state and district assess-

    ments that focus on vocabulary. Instead,

    the CSM team is encouraging district sci-

    ence and mathematics teachers, instruc-

    tional specialists, coordinators and admin-

    istrators to become aware of this issue of

    confusing language between science and

    mathematics and to address this serious

    problem for our students. Equally impor-

    tant is that state and national assessment

    leaders and policymakers have a similarunderstanding of this issue and the rami-

    cations for our nations quest to improve

    STEM education.

    Our PurposeThe purpose of this article is to alert

    science and mathematics teachers and other

    STEM stakeholders to the profound effect

    that confusing language between science

    and mathematics has on students under-

    standing of each discipline. However, thevalue is not in identifying and sharing what

    the CSMteam and others have discovered.

    More importantly, science and mathematics

    teachers and their students should discover

    and clarify confusing language for them-

    selves through rich conversations. Teach-

    ers can have these rich conversations only if

    the administration provides adequate daily team planning time. Subsequently, similar rich

    conversations should occur in classrooms among students and teachers.

    Enhancing Science Knowledge Trough ProvenInstructional Strategies

    by Gloria Gresham, et. al.

    Many elementary teachers arechallenged to t science into their dailyschedules partially due to reading and math

    expectations reiterated in the No Child Left

    Behind Acts goal of all students perform-

    ing at or above grade level by the year 2014

    (ED.gov, 2008). Oftentimes, in an effort to

    meet accountability expectations, elemen-

    tary teachers concentrate on reading and

    math instruction and nd that they are left

    with precious little time to devote to science.

    Moreover, numerous teachers in elementary

    schools discover learning science content

    challenging for students because the vocab-

    ulary of science is more specialized with new

    words being frequently introduced through-

    out the text (Baer & Nourie, 1993; Ediger,

    2002). The faculty of an elementary campus

    in East Texas was no different in that teach-

    ers found the teaching of science a constant

    challenge. For these instructors, a conse-

    quence of their reading and math focus was

    that their state standardized test scores inscience, the Texas Assessment of Academic

    Skills (TAKS), were lower than reading and

    mathematics scores. In fact, science TAKS

    scores had prevented the campus from

    performing above the Acceptable level on

    the Texas accountability ranking system for

    several years.

    After much discussion, the teachers

    decided to attack this concern by engag-

    ing the assistance of three local universityprofessors. First, the professors facilitated a

    review of current literature relating to effec-

    tive instructional strategies and the teach-

    ing of science. Through the review, teach-

    ers gained knowledge of the importance of

    inquiry learning, of using vocabulary and

    comprehension strategies to boost reading,

    of employing a method for releasing cogni-

    tive responsibility to students, and of how

    to engage students in science learning in ameaningful way.

    In examining research on inquiry

    learning, the teachers discovered that in-

    quiry is the foundation of science instruction

    because learning science requires students

    to intellectually and physically interact with

    and question content while the instructor

    moderates the process through explana-

    tions, clarications, and examinations

    (Hammerman, 2006. p. xxv). Teachers alsofound that Teaching Standard A of the Na-

    tional Science Education Standards (1996)

    expected them to deliver an inquiry-based

    science program and assess the learning

    strategies to ascertain student development

    of science knowledge. A proven inquiry plan-

    ning model was analyzed, the 5 E Learn-

    ing Cycle Model, which included a ve-step

    lesson delivery approach: Engagement,

    Exploration, Explanation, Elaboration, andEvaluation (Coe, 2001). Engagement referred

    to an object, event, or question to engage

    students and connecting to what students

    know and can do. Exploration employed

    hands-on activities with teacher guidance.

    The Explanation phase consisted of students

    explaining concepts learned in Exploration,

    and the teacher introducing new concepts

    and clarifying concepts. Elaboration was the

    step where students applied learning. Final-

    ly, Evaluation included students assessingtheir own knowledge as well as the teacher

    assessing knowledge gained.

    In their review of vocabulary and read-

    ing instructional strategies, teachers discov-

    ered that since reading capacity affects stu-

    dents grasp of science content, systematic

    and explicit vocabulary instruction is one of

    the most important instructional interven-

    tions teachers can employ to aide student

    understanding (Marzano, Pickering, & Pol-

    lock, 2006). In a similar manner, compre-hension is enhanced through implementing

    modeling strategies and graphic organizers.

    Shared reading, echo reading, choral read-

    ing, and paired reading are modeling strate-

    gies teachers can employ to assist readers

    with challenging material (Carbo, 1997).

    Shared reading involves the teacher plac-

    ing text in front of students, reading while

    pointing to the words, and pausing to ask

    questions. Echo reading, according to Carbo(1997), is when the teacher discusses a

    passage and reads the text aloud while the

    students follow along in the text. Then, the

    teacher reads a small portion of the text,

    and students read it back. Choral reading

    includes reading a passage in unison, and

    paired reading is when two students take

    turns reading a passage. When students are

    uent and can read with little support, they

    engage in independent or silent reading.

    It was discovered that responding to

    reading assists students in constructing

    meaning and comprehending text. Marzano,

    Pickering, & Pollock (2006) found that us-

    ing non-linguistic organizers and identifying

    similarities and differences increases stu-

    dent performance. Reading and then writing

    about what one reads also promotes critical-

    thinking and conceptual understanding

    (Baker, et al., 2004; Wallace, Hand, & Prain,

    2004). More importantly for this study in

    particular, the teachers found that requir-

    ing students to complete various writing

    exercises, such as exploratory writing, eld

    notes, description, and written discussion of

    experiments, are critical elements of inquiry

    learning and science instruction (Ryan and

    Walking-Woman 2000).

    The next review of literature involved

    examining the concept of releasing or trans-

    ferring cognitive responsibility for learning

    from teacher to student. According to the

    Pearson and Gallagher model, the respon-sibility for completing a task follows this

    sequence: (1) teacher responsibility, (2) joint

    responsibility between the teacher and stu-

    dents, and (3) student responsibility (1983).

    Diehl (2008) dened this release of respon-

    sibility, from outer control to inner control

    (p. 1). It is the outer control to inner control

    that allows students to become independent

    learners.

    Because active intellectual and physi-

    cal engagement is critical to learning, teach-

    ers also reviewed what experts said about

    social interaction and learning. They found

    that Vygotskys (1978) theory of learning is

    embedded in social interaction. Vygotsky

    believed that a students learning is inter-

    psychological; meaning is gained through

    interaction with others. Schlechty (2001)

    described this collaboration or afliation as

    displayed by interaction from instructor tostudent, student to instructor, and student

    to student (2001). When considering both

    the importance of social learning and the

    Gradual Release of Responsibility Model,

    teachers detected that collaborative work is

    a method of gradually releasing responsi-

    bility. To release responsibility was viewed

    by the teachers as a process, moving from

    a teacher-directed whole group lesson, to

    small group participation, to partner work,

    and nally to the individual. Small group

    interaction, in particular, provides an av-

    enue for greater participation, feedback, and

    mutual construction of meaning when com-

    pared to whole-group participation (Evertson

    & Emmer, 2009).

    As the teachers synthesized ndings

    from the literature review, they crafted a

    plan of attack. Since the district required

    implementation of a curriculum aligned to

    the Texas Essential Knowledge and Skills(TEKS) that outlined units of study, the

    teachers decided to build on this curricu-

    lum and focus on a structured planning

    approach that included information from

    the literature review. Their solution was to

    create and employ a ve-day planning and

    instruction model titled the Science Con-

    tent Weekly Planning Model (see Figure 1),

    reminiscent of the 5 E Learning Cycle Model.

    This new model would include specic read-ing and writing strategies, a schedule to im-

    plement the concept of the gradual release of

    responsibility, and specially designed forma-

    tive and summative assessments. For ex-

    ample, each week of instruction ended with

    a short, TAKS-formatted practice and elimi-

    nated the test preparation drill and kill ac-

    tivities that had revealed little success in the

    past. In addition, a new type of assessment

    was added that required students to reect

    upon their ndings and synthesize results.

    Weekly, teachers focused on one par-

    ticular standard of the TEKS outlined in

    the districts aligned curriculum four to ve

    week unit of study. Each day of the week

    had specic purposes and instructional

    strategies intended to foster inquiry learning

    and comprehension of science knowledge.

    Teachers believed this consistency would

    provide structure, and, that over time, stu-

    dents would gradually learn the purpose for

    each days instruction as well as how that

    day was an important part of the overall

    plan.

    Day OneThis days intent was setting the

    weeks objective, engaging attention, con-

    ducting a eld investigation, debrieng, and

    transferring learning. The objective was stat-

    ed in student-friendly terms, formally writ-

    ten, and posted for the week. For example,

    the objective for the fourth grade TEKS, 5 (C)compare and contrast a variety of mixtures

    and solutions such as rocks in sand, sand

    in water, or sugar in water might look like

    this, You will learn what the word mixture

    means and tell how a variety of mixtures are

    alike and how they are different. Following

    the discussion of the weeks purpose, the

    teachers assessed student prior knowledge

    relating to the upcoming eld investigation

    by implementing a graphic organizer suchas a Circle Map. A Circle Map is one of eight

    Thinking Maps used to dene what stu-

    dents know (Hyerle, 1996).

    Next, an inquiry-based eld investiga-

    tion relating to the content was introduced

    to students as a problem to solve (National

    Science Education Standards, 1996). In

    teams, students noted the stated problem in

    their science journals, crafted and applied

    their hypotheses, recorded results, and thencomposed conclusions. Teachers served as

    guides to assist and clarify understanding

    as small groups of students completed their

    investigation. For example, when students

    studied mixtures, the stated problem was

    to determine how to separate sand from

    iron lings in a closed, glass tube. Students

    actively engaged in solving this problem and

    were thrown into the content, the eld in-

    vestigation, prior to formal instruction over

    vocabulary. The science class ended with

    teachers questioning students about their

    learning as a formative assessment provid-

    ing a foundation for the transfer of learning

    to the next day (Sousa, 2006).

    Day TwoFirst, teachers used graphic organizers or posed questions to access and review con-

    tent learned from the previous day (Marzano, Pickering, & Pollock, 2006). Next was a text

    connection to the previous days eld investigation. Students would spend time in learningthe meanings of the vocabulary introduced during the previous days eld investigation.

    During vocabulary instruction, teachers implemented strategies for vocabulary building,

    as well as content reading and writing connections. Vocabulary strategies implemented

    such as Word Charts required students to craft denitions, dene characteristics, and list

    examples and non-examples of each term. Then, content reading strategies were employed

    to provide a way for students to work expository text relating to the eld investigation

    content. Since not all students were instructionally ready to read grade level text, teach-

    ers provided opportunities for less able readers to see effective reading being modeled. The

    strategies were chosen were based on the needs of the students.

    Students who needed some support worked in pairs while independent, uent read-

    ers worked alone. Teachers met individually and in small groups with readers requiring

    more reading support. Moving from strategy one, shared reading, to strategy ve, silent/

    independent reading, each strategy required increasingly more reading independence of

    students and less modeling by teachers (Carbo, 1997). As the year progressed, all of the fol-

    lowing strategies were utilized.

    1. Shared Reading The teacher read the story while pointing out key words and pausing

    to ask questions.

    2. Echo Reading The teacher read aloud a small portion of the text, and the students

    read the same portion back to the teacher.3. Choral Reading The teacher and students read a passage in unison.

    4. Paired Reading Two students alternated reading a passage. The teacher paired a more

    able reader with a less able reader.

    5. Silent/Independent Reading Each student read alone.

    Two types of formative assessment of student work were employed. First, students

    completed graphic organizers in their science journals in response to readings. Text struc-

    ture determined which type of thinking was required and which type of organizer was ap-

    propriate. Eight different organizers called Thinking Maps (Hyerle, 1996) plus Venn Dia-

    grams were used during the year (see Figure 2).

    the day by answering questions such as, What was learned? and writing in their science

    journals (see Figure 3).

    The graphic organizer and reection provided daily formative assessment of student

    understanding. Finally, the days lesson closed by previewing the next days content.

    Day ThreeTeachers opened Day Three with in-

    struction that purposefully activated knowl-

    edge acquired in Day One and Day Two,

    explicitly lling in needed content or clearing

    up any misconceptions. PowerPoint pre-

    sentations, demonstrations, and video clips

    were utilized for instructional input as well

    as reinforcement. On Day Three, the focus

    of the lesson was on the concept of cogni-

    tive responsibility gradually shifting from

    teacher to students (Pearson and Gallagher,

    1983). First, students worked in teams to

    construct knowledge through engaging in,

    inquiry-based group activities. One suchactivity was learning the difference between

    inherited and learned behaviors through a

    scenario concerning horse behaviors and

    physical traits. Next, to continue the process

    of releasing more cognitive responsibility,

    students were paired and engaged in other

    application activities to rehearse content.

    The class ended with teachers asking stu-

    dents to individually reect upon what was

    learned, thus providing formative assess-

    ment. As a result of these activities on DayThree, students rehearsed content through

    whole group, small group, partner format,

    and nally individual reection, thereby

    following the process of gradually releasing

    cognitive responsibility from whole group

    instruction by the teacher to individual stu-

    dent reection.

    Day FourThe cognitive shift of responsibil-

    ity continued on Day Four. After activating

    students knowledge of the previous days

    content, students responded orally to ques-

    tions that required closed (one-answer) and

    open-ended responses (more than one an-

    swer). Individually, students engaged with

    text passages that were previously read on

    Tuesday and supported answers with evi-

    dence from the text. The intent was to pro-

    vide students with rehearsal so they would

    have additional opportunities to retain con-

    tent (Sousa, 2006). The role of the teachers

    in this strategy was to guide and support.

    Next, students engaged in a writing activity

    that provided connection to content. Teach-

    ers assigned one of the following as a writing

    activity, summary, gist, main idea, or three

    facts learned, and charged students with the

    task of reecting upon the weeks content

    in their science journal. These opportuni-

    ties provided the teachers with an additional

    means of formative assessment prior to the

    next days formal, summative assessment.The class concluded with students reviewing

    the days learning and teachers previewing

    the events of the next day.

    Day FiveThe nal step in the Science content

    Model Planning Model was a formal, sum-

    mative assessment involving two types of as-

    sessment items: application-level, multiple-

    choice questions and a written assessment

    (Khatri, Reeve, & Kane, 1998). The short,multi-choice questions were developed to

    mirror the format of the state standardized,

    fth grade science exam (TAKS). The short

    answer written assessment consisted of a

    scenario that required students to think crit-

    ically and synthesize what they had learned

    during the week.

    Evidence of SuccessThe Science Content Weekly Plan-

    ning Model was instrumental in focusing

    instruction on science at the elementary

    level and in implementing proven instruc-

    tional strategies that led to academic suc-

    cess and science knowledge gain. At the end

    of the second year of implementation, the

    campus achieved the rating of Recognized,

    the intended goal. Even more exciting was

    the change in attitude toward science that students exhibited. The teachers reported that

    students were eager to walk into the room; You could see it in their eyes when they graced

    the door, exclaimed one teacher. Observations revealed that during science class, stu-

    dents were actively engaged, responsible for their learning, and worked cooperatively. One

    example of this success in science was shown by a student identied for special educationservices. Previously, the student had never passed any state examination. Over the course

    of the year, the student began to raise his hand to answer questions and participated in

    all group and individual work. His special education teacher asked his teacher what he

    was doing to inspire the student. The special education teacher noticed a marked, positive

    change in the students retention capacity and learning attitude. When the state science as-

    sessment results were received, this student passed!

    In addition, responses by the teachers involved in The Science Content Weekly Plan-

    ning Model revealed that the model was easy to implement because it provided more a

    consistent structure of daily activities and simplied planning. Students and teachers knewwhat was expected and focused learning on identied state curriculum standards. Included

    in the Model are proven instructional strategies that emphasize students constructing sci-

    ence knowledge through an inquiry approach.

    AbstractIn an efort to glean insights into the Dal-

    las Region Science and Engineering Fair (DRSEF)

    participation rom Dallas/Fort Worth (DFW) areaindependent school districts (ISDs) as a measure ostudent interest and competitiveness in Secondary Sci-ence Education (grades 7 12), a research analysis o12 years o DRSEF data (1999 - 2010) was undertak-en, with specic ocus on the most recent 4-year data(2007 - 2010). Plano ISD, with 11.7% o the total an-nual student enrollment share o the area ISDs, leadsthe pack with 46.9% share o the total projects partici-pating at the DRSEF and a participation index (PI)o 402, indicating a more-than-our-times the averagelikelihood o participation at the competitive event.Coppell ISD with only 2.3% o the student enroll-ment share had a participation index o 322. Amongthe 13 major ISDs included in the analysis, DallasISD with the largest student enrollment (30% o total)ranked a distant 8th (PI = 60) and Garland ISD withthe second-largest (12.6%) student enrollment ranked7th (PI = 70) in DRSEF participation index. Interest-ingly, Plano ISD, with the highest number o projectsentering DRSEF in both Physical and Lie sciences

    categories, had higher number o project entries in thePhysical sciences category than in Lie sciences cat-egory. By contrast, Dallas, Garland and McKinney,three other ISDs with signicant number o partici-pating projects, had more projects in Lie sciences cat-egory than in Physical sciences. Te ndings reportedhere have signicant educational (science education, inparticular) and community implications in the DFWmetropolis.

    Introduction

    Another year of Elementary and Sec-ondary Schools Science Fair competitions

    has gone by for the Independent School

    Districts (ISDs) in DFW metroplex. As is

    well known, participants compete in several

    science-subject categories at their schools,

    rst. The winners then advance to the dis-

    trict level and from there go to regional, state

    and international level competitions. With

    hundreds of thousands of dollars at stake in

    scholarships and awards, the competition atthis event is intense and at the highest level

    can be termed as Science Olympiad for pre-

    teens and teens.

    Speaking of teens competing in

    Science, let us look at some facts as they

    relate to Science literacy of U.S. students in

    the international context. In a recent inter-

    national exam Program for International

    Student Assessment (PISA), 2006 - that is

    supposed to assess the ability of 15-year-

    olds to apply Math and Science knowledge in

    real-life situation, students from the United

    states ranked 21st among the 30 countries

    of the Organization for Economic Coopera-

    tion and Development (OECD) that were part

    of this competitive assessment (1). Results

    from the study showed that U.S. students

    scored lower than the OECD average and

    that they lagged behind their peers in 6 of

    the 27 non-OECD countries in Science lit-eracy (1, 2). Although there are differing

    opinions among experts on the validity of

    this study, results nevertheless support the

    notion that all is not well with the Science

    Education in the United States; perhaps

    there is either a declining interest in Science

    education among U.S. students or quality of

    Science education in the nation, something

    which is not easy to measure, has been de-

    teriorating.

    Another report (3) also provides sup-

    porting evidence that even though overall

    enrollment in Science and Technology (S&T)

    elds increased in the last 15 years, the rel-

    ative share of S&T enrollment has declined.

    The policy report also pointed out that the

    existing statistical data are not adequate for

    measuring and analyzing the levels of stu-

    dent interest. With this backdrop, the cur-

    rent study was undertaken with the follow-

    ing objectives:

    To analyze the recent trends in Dallas

    Regional Science and Engineering Fair

    (DRSEF) participation, as a measure of

    interest/competitiveness in science edu-

    cation, at the junior (grades 7 & 8) and

    senior (grades 9 12) divisions of DFW

    area ISDs of public-school system, char-

    ter schools and other private institutions

    To share the case-study analytical nd-

    ings with the science coordinators and/

    or administrators of ISDs so that with the

    supporting evidence they have of their

    level of Science-fair participation vis--vis

    their peers they can make an informed

    decision on improving their science edu-

    cation

    To publicize the results of the case study

    so that legislators and policy makers at

    the State-level and administrators of ISDs

    devise ways for maintaining (whereverISDs have an edge over others) and/or

    improving Science education in ISDs

    could be made both at the division level and science-category level.

    Analytical Findings

    Overall senior-division science-fair participation trends (1999 2010)The long-term trend on science-fair participation at the senior-division level is pre-

    sented in Fig. 1. Although substantial year-to-year variation is discernible (blue line), there

    is a declining trend (red trend line) in general. Average number of project entries in the

    DRSEF senior division in the last six years (2005-2010) was 14% lower than that in the

    prior six years (1999-2004), while the average student enrollment increased 17% (Fig. 2)

    between 1999 and 2009 academic years.

    NB: DRSEF data or 2010 in Fig 1 above corresponds to academic-year studentenrollment data or 2009 in Fig 2 and so on.

    The declining numbers of senior-level projects observed above can be explained, at

    least in part, by the signicant reduction in DRSEF participation from two large ISDs, Rich-

    ardson and Irving. Participation from other new ISDs such as Coppell, McKinney, Frisco,

    Cedar Hill, De Soto and Lancaster in the last four years was not enough to offset the declin-ing trend. Evidently, the decline in participation at DRSEF is even steeper at the junior-

    level (trend data not available; Dr. S. Dalley, personal communication).

    ISDs participation trends by division in the last four years (2007 2010)Plano ISD has consistently had the lions share of projects participating in DRSEF in

    both junior and senior divisions, followed by Dallas ISD (Table 1). It is important to note

    that Coppell and McKinney ISDs have steadily increased their share of participating proj-

    ects at DRSEF over the last four years, surpassing Garland ISD in the last two years. Also

    signicant to note is that Dallas ISD whose participation at the fair has been decreasing

    since 2007 has rebounded back in 2010, with a total of 113 projects, majority of which

    (65%) was at the junior-division.

    ISDs participation trends by science-category in the last three years (2007 2010)Table 2 shows the most recent 4-year DFW area-ISDs participation trend in Physi-

    cal vs. Life Sciences categories. Plano ISD, with the highest number of projects entering

    DRSEF in both Physical and Life sciences categories, had higher number of project entries

    in the Physical sciences category than in Life sciences category. By contrast, Dallas,

    Garland and McKinney, three other ISDs with signicant number of participating projects

    had more projects in Life sciences category than in Physical sciences. Coppell ISD partici-

    ISDs participation relative to student enrollment in the last four years (2007 2010)Among the major ISDs in the DFW Metroplex (Table 3), Plano ISD, with a share of

    11.7% of the student enrollment had not only had the highest number of projects partici-

    pating at the DRSEF (46.9% of total) but also the highest number of participation per 1000students enrolled (11.61 PPT) in grades 7 12 that make up the combined junior and se-

    nior divisions of the Dallas regional-level competition. Dallas ISD accounted for 2nd high-

    est number of participating projects, on an average, but ranks 8th in PPT, although it ranks

    rst (30.0%) among the DFW area ISDs in the percent share of student enrollment.

    Computation of a metric called Participation Index (PI) by normalizing the participa-

    tion data with the student enrollment data (see denition above), allows us to compare the

    DRSEF participation of various ISDs on the same scale. Therefore, PI is a true reection of

    ISD participation at the competitive DRSEF. Note that PI of 100 is an average participation

    >100 is above-average, whereas

    ConclusionIf this study provides some supporting

    evidence to the widely prevailing perception

    that student-interest in science educationin the United States may be declining, then

    there is a need to explore the subject further

    and understand what factors might be con-

    tributing to this decline. Based on the body

    of knowledge available to us so far (1, 2, 3)

    and current public and policy discussions/

    debate happening on Science issues around

    the country, it appears that a variety of fac-

    tors demographic, cultural and/or social

    - contributing either directly or acting in

    concert with other factors, may be responsi-ble for the not-so-good state of affairs in the

    nations science education today:

    Science curriculum

    An environment where the teaching of

    Science and Math may be perceived as

    burdensome

    Quality of teachers and science teaching

    Challenges in federal funding of educa-

    tion relative to other priorities

    Value placed by the general public on

    education vs. athletics

    In spite of the prior evidence (1, 2, 3)

    and ndings of this study suggesting that

    there has been a declining interest among

    U.S. students in science education, it is

    heartening to note that at least one of the

    contributing factors listed above may be

    changing for the better funding for educa-

    tion, in general, and science education, inparticular. President Obama has promised

    to increase funding for Science education.

    Similar to honoring winning athletes at the

    White House, President Obama hosted a

    White House Science Fair, the rst ever,

    on Oct 18, 2010, that fullls his promise of

    Educate to Innovate campaign he launched

    in Nov 2009 to inspire boys and girls to exce

    in math and science. This is a welcome step,

    however symbolic it may be, in the Federal

    governments efforts to accord science therespect and the place it deserves and in

    boosting the morale of all those who are in-

    terested in working towards the betterment

    of science education in the United States.

    In addition to the immediate implica-

    tions of this study to the science education

    of DFW-area ISDs, what are the benets of

    this study to society at large? An increased

    participation in science fair not only stimu-

    lates student interest in scientic inquiryand experimentation, but it also promotes

    (a) public awareness about current science

    issues and (b) a two-way dialogue and de-

    bate between scientists and society at the

    local level (6).

    What can we do to promote DRSEFparticipation?

    Schools (science teachers) need to publi-

    cize better and reinforce the importance

    of student participation in science fairs,

    especially at the high-school level

    Make participation in science fairs or sci-

    ence research projects mandatory

    Offer extra credit to students for partici-

    pation in science fairs or science research

    projects

    Have award winners at the science fair

    share their project ndings and participa-

    tion experiences at school general assem-bly at their own schools as well as other

    area schools

    Encourage scientists engaged in research

    at the local universities and/or research

    institutes to share their scientic activi-

    ties and/or act as mentors to budding

    scientists at schools
