Who is at fault?
The college professor said, "Such wrong in the student is a shame, Lack of preparation in high school is to blame.“Said the high school teacher, "Good heavens, that boy is a fool.The fault, of course, is with the middle school."The middle school teacher said, "From such stupidity may I be spared, They send him to me so unprepared.“The elementary teacher said, "The kindergartners are block-heads all. They call it preparation; why, it's worse than none at all.“The kindergarten teacher said, "Such lack of training never did I see, What kind of mother must that woman be.“The mother said, "Poor helpless child, he's not to blameFor you see, his father's folks are all the same." Said the father, at the end of the line,"I doubt the rascal's even mine!"

If you were a struggling student in the school where you currently teach explain:
a) How would the teachers know you are struggling?b) What kind of help would you receive for reading,
math, and social difficulties?c) Who would recommend the help?d) Who would provide the help?e) For how long would you receive help?f) How would the school know when you do not need
help or you need a different kind of support?

Our purpose today
You will learn• some potential changes for helping struggling
students• research-supported instruction (math)
– CRA; think alouds; strategy instruction
• ideas for implementation• how to assess and screen students

Special Education vs. General Education
RtI- Tiered Instruction and Intervention
Tier 1: BenchmarkSchool-wide (not Title I) research-supported instruction available to ALL students including standards-aligned concepts and competencies, and instruction.
Tier 2: StrategicAcademic and behavioral strategies, methodologies and practices designed for students not making expected progress in the standards-aligned system. These students are at risk for academic failure.
Tier 3: Intensive InterventionsAcademic and behavioral strategies, methodologies and practices designed for students significantly lagging behind established grade-level benchmarks in the standards aligned system. © Witzel, 2010 11
*******Your Turn*******
• What are your tier 1 instructional ideas?– Name the instruction– What evidence supports your instruction?
• What are your tier 2 interventions?– Name the intervention– What evidence supports your intervention?
© Witzel, 2010 12
What will we do to prepare for RtI in Math, where RtI was not initially
intended?1. Possible interventions2. Research synthesis and meta-analyses3. Progress Monitoring

Interventions
Content and Instruction
Explicit Instruction• Explicit instruction consistently resulted in large effects
both for learning single skills as well as multiple related skills in complex problem solving.
• How do we balance teacher-led instruction with student engagement?
• These findings must be tempered by the fact that the measures on which the effect sizes were calculated were all researcher-developed. Gersten, Baker, & Chard (2008)
© Witzel, 201017
Explicit Instruction
The National Mathematics Advisory Panel stated that “Explicit systematic instruction typically entails teachers explaining and demonstrating specific strategies and allowing students many opportunities to ask and answer questions and to think about the decisions they make while solving problems” (p.48).

Explicit Teaching Steps Best Practices consistent in math research
literature:– Advance Organizer– Model– Guided Practice– Independent Practice– Feedback– Maintenance and Generalization
Observe these steps in http://etv.jmu.edu/mathvids/© Witzel, 2010 19
A sample lesson format
1. Warm-up (maintenance) 2. Statement of relevance3. Describe / Model4. Guided Practice5. Independent Practice (process feedback)6. Word Problem (generalization)7. ***Fluency Probe (product feedback)
© Witzel, 2010 20
Let’s try some examples
• First some modeling “I do it”
• Then well work together on some “We do it”
• Then you try some on your own “You do it”
© Witzel, 2010 21
Models of Information TransferCecil Mercer
• “I do it”• “We do it”• “You do it”
Matt McGueThe 5 steps to Apprenticeship1. “I do, you watch, we talk”2. “I do, you help, we talk”3. “You do, I help, we talk”4. “You do, I watch, we talk”5. “You do, someone else
watches”
© Witzel, 2010 22
Feedback and Generalization
• Appropriate feedback
• When should homework involve multiple independent practice problems?
• When should homework involve math problems that explain the application in their own lives?
© Witzel, 2010 23
Grouping strategies
• Station and center teaching• Small group help• Peers
• Keep students moving efficiently through groups. The younger the students, the less time per activity and the smaller the group.
© Witzel, 2010 24
Peer-assisted learning
• Peer assisted learning provides extensive opportunities for students to practice solving math problems and to interact with peers about mathematics
© Witzel, 2010 25
Peer assisted-learning
• Results have been consistently positive if:– Student’s work in pairs and the activities have a
clear structure.– The pairs include students at differing ability
levels. – Both students play the role of tutor for some of
the time. – Students are trained in the procedures necessary
to assume the role of tutor.
© Witzel, 201026
Peer assisted-learning
• Peer assisted-learning appears to benefit both lower- and higher-performing learners because:– When serving as tutors, less proficient students
attended to details of problems and the approaches their partner used to problem solve
– More proficient students solidified their conceptual understanding of mathematics by having to explain their problem solving to their peers
© Witzel, 201027
Feedback to Students about their Performance
• Providing students with feedback about their performance resulted in moderately large effects.
• For students with disabilities, these effects were smaller.

Clarity in our work with students
What do we focus on?• General Education Curriculum-and-• Number Sense• Basic Facts and Operational Accuracy• Basic Facts and Operational Fluency• Fractions, Decimals, and Proportions• Word Problem Solving
© Witzel, 2010 30
Practice operational facility
• The RtI Panel (Gersten, Beckman, Clarke, Foegen, Marsh, Star, and Witzel, 2009) concluded that all students (K-8) receiving interventions should receive at least 10 minutes of practice per day in fact fluency.
• K-5 should focus on whole numbers• 4-8 should focus on rational numbers
© Witzel, 2010 31
Number Sense (Chard, 2006)
• It has been found that students who evidence math difficulties early struggle in understanding and task performance with number sense concepts, such as counting, quantification or magnitude of number, number to numeral identification, base-10 and place value, and fluent arithmetic strategies.

• The RtI Panel (Gersten, Beckman, Clarke, Foegen, Marsh, Star, and Witzel, 2009) concluded that all students (K-8) receiving interventions should receive at least 10 minutes of practice per day in fact fluency.
• K-5 should focus on whole numbers• 4-8 should focus on rational numbers

Findings: Visuals and Graphic Depictions of Problems (CRA)
• Graphic representations of problems and concepts are widely used in texts both in the U.S. and in nations that perform well in international comparisons
• Teaching students to use graphic representations of the underlying concepts of a problem results in moderate effects.
© Witzel, 201044
Findings: Visuals and Graphic Depictions of Problems
• Effects were larger when teachers provided students with multiple opportunities to apply graphic representations to specific problems
• Effects were also enhanced when teachers taught students to select appropriate graphic representation and why a particular representation was most suitable
© Witzel, 2010 45
Findings: Visuals and Graphic Depictions of Problems
• When teachers used graphic representations to demonstrate problems only, results were much less consistent.
• Visuals were not particularly useful unless students were provided opportunities to practice using them.
• Highest effect sizes were for CRA with clear and explicit stepwise consistency (Gersten et al., 2009; Witzel, Mercer, & Miller, 2003; Witzel, 2005)
© Witzel, 201046
CRA
• Concrete to Representational to Abstract Sequence of Instruction (CRA)
• Concrete (expeditious use of manipulatives)• pictorial Representations• Abstract procedures

Let’s try some CRA from Multisensory Algebra and the Middle School
Intervention Series
• From the basic facts• To variations that often cause trouble• To crazy things like fractions• To simple equations

CRA with fractions
• After teaching her students subtraction and negative integers through the fraction computation using sticks, Mrs. Straube was able to transition into more abstract terms

Prepare instruction as a series of events
CRA with more difficult fractions
• 5/8 ÷ 2/3
15/16
© Witzel, 2010 53
Divide the numerator into 3 groups per tally mark. Then, count the groups of 2.
Lay down an equivalent fraction until you have a whole number of groups
Common Sense for CRA(From Witzel, Riccomini, & Schneider, 2008)
• Multimodal forms of math acquisition to aid memory and retrieval (Engelkamp & Zimmer, 1990; Nilsson, 2000)
• Multiple learning styles are being met to aid relevance and motivation (Oberer, 2003)
• Meaningful manipulations of materials allow students to rationalize abstract mathematics
(Demby, 1997; Noice & Noice, 2001)
• Provides an alternative to algorithm memorization of math rules
• Transportable without concrete materials (Witzel & Allsopp, 2007)
© Witzel, 2010 54
Who benefits from CRA instruction?
• Students with memory concerns• Not an algorithm stepwise approach• Pictorial step allows students to carry manipulative everywhere
• Students with low on-task performance• Students with poor math background
and• Students who lack conceptual knowledge
-or-• Students who have difficulty relating the concept to the
math skill / task© Witzel, 2010 55

Measurement - relates the concepts of measurement to similarity and proportionality in real-world situations.
Extend Explicit Instruction to Include Student Think-Alouds
• Encouraging students to verbalize their thinking and talk about the steps they used in solving a problem – was consistently effective
• Verbalizing steps in problem solving was an important ingredient in addressing students’ impulsivity directly (Schunk & Cox, 1986)
© Witzel, 201059
Think alouds within explicit instruction
• Explicit instruction requires an instructional sequence that involves the teacher modeling strategies or procedural steps by acting out the problem and verbally describing what thought processes the students should perform. By explaining the reasoning of each step students can link accurate answers to conceptual understanding.

Algebraic - The student describes, analyzes, and generalizes a wide variety of patterns, relations, and functions. (MA.D.1.3)Operations - selects the appropriate operation to solve problems involving addition, subtraction, multiplication, and division of rational numbers, ratios, proportions, and percents, including the appropriate application of the algebraic order of operations. (MA.A.3.3)

© Witzel, 2010 63
Findings: Student Think-Alouds
• Verbalizing appeared to be most effective when multiple approaches to solving problems were demonstrated and students were encouraged to think-aloud as they solved multiple practice problems.

Learning Strategies• RIDE
– Read the problem correctly– Identify the relevant information– Determine the operations and unit for expressing the
answer– Enter the correct numbers and calculate then check
• RAPQ (adapted)– Read the problem– Ask what the point is and what is needed to answer– Put the ideas in your own words (paraphrase on paper)– Question your answer and the equation
• See additional learning strategies– http://coe.jmu.edu/learningtoolbox

Schema-based strategies (see the work of Jitendra and Montague)
• Vary Size of groups unknown: – In school, there are 12 calculators for 24 students to share. How many
students will share each calculator?
• Whole unknown: – Isabelle earned $30 for each day that she worked at the
church store. She worked for 5 days. How much money did she earn?
• Referent unknown (compared is part of referent): Laura and Isha went running. Isha ran 8 laps. She ran 1/2 as many laps as Laura. How many laps did Laura run?

Sample Word Problems
1. The map shows that you have traveled 4 out of 10 miles on your trip. Your friend tells you that you are 3/5 of the way there. Are you 3/5 there? Show why or why not using abstract notation
2. The temperature was 4 degrees below zero. Recently, the temperature rose up 5 degrees. What is the temperature as it relates to zero now? (1) Set up the equation; (2) Explain your reasoning; and (3) Solve the problem.

Summary• Results of these research syntheses suggest that
students who are struggling with mathematics benefit from:– Verbalizing and use of visuals for problem solving;– Explicit instruction in how to use specific skills and multi-
step strategies;– Their teachers receiving feedback from formative
assessment to modify instruction;– Peer-assisted learning opportunities in which they focus
on problem details and observe models of proficient students’ problem solving

Math is different
“ Do not keep forever on the public road, going only where others have gone, and following on after the other like a flock of sheep. Leave the beaten track occasionally and dive into the woods. Every time you do so you will be certain to find something that you have never seen before” (AGB, 1914).
