Inquiry in the Standards

Inquiry is a multifaceted activity that involves making observations; posing questions; examining books and other sources of information to see what is already known; planning investigations; reviewing what is already known in light of experimental evidence; using tools to gather, analyze, and interpret data; proposing answers, explanations, and predictions; and communicating the results. Inquiry requires identification of assumptions, use of critical and logical thinking, and consideration of alternative explanations. (p. 23)

Inquiry in the classroom

Developing the ability to understand and engage in this kind of activity requires direct experience and continued practice with the processes of inquiry.

Students do not come to understand inquiry simply by learning words such as "hypothesis" and "inference" or by memorizing procedures such as "the steps of the scientific method." They must experience inquiry directly to gain a deep understanding of its characteristics.

Yet experience in itself is not sufficient. Experience and understanding must go together. Teachers need to introduce students to the fundamental elements of inquiry. They must also assist students to reflect on the characteristics of the processes in which they are engaged.

An historical perspective

Before 1900 – most educators viewed science as a body of knowledge learned through direct instruction.

1909 – John Dewey◦ Science as a way of thinking and an

attitude of mind.

◦ Science is more than a body of knowledge to be learned; there is a process or method to learn as well.

◦ Democratic teaching, skills for life vs. facts, pragmatism (learn by doing)

A historical perspective

By the 1950s and 1960s,

inquiry as an approach to

teaching science was

becoming evident.

Joseph Schwab (1960s)

◦ Science should be viewed as

conceptual structures that

were revised as the result of

new evidence.

◦ Science teaching and learning

should reflect this perspective.

A historical perspective

Joseph Schwab (cont.)

◦ Science teachers should look first to the laboratory and use these experiences to lead rather than follow the classroom phase of science teaching.

◦ Students should work in the laboratory before being introduced to the formal explanation of scientific concepts and principles.

◦ Evidence should build to explanations and the refinement of explanations.

“enquiry into enquiry”

Approach: teachers provide students with readings and reports about scientific research.

They discuss the details of research: problems, data, role of technology, interpretations, conclusions.

When possible, students read conflicting reports, other uses of evidence, etc.

Allows students to build an understanding of what constitutes scientific knowledge and how it is produced.

Making the case for inquiry

Making the case for inquiry

Research Finding #1: Understanding

science is more than knowing facts.

Research Finding #2: Students build new

knowledge and understand what they

already know and believe.

Research Finding #3: Students formulate

new knowledge by modifying and refining

their current concepts and by adding new

concepts to what they already know.

Research Finding #4: Learning is mediated by

the social environment in which learners

interact with others.

Research Finding #5: Effective learning requires

that students take control of their own learning.

Research Finding #6: The ability to apply

knowledge to novel situations, that is, transfer

of learning, is affected by the degree to which

students learn with understanding.

Fundamental Understandings About

Scientific InquiryGrades K-4

Scientific investigations involve asking and answering a question and comparing the answer with what scientists already know about the world.

Scientists use different kinds of investigations depending on the questions they are trying to answer.

Simple instruments, such as magnifiers, thermometers, and rulers, provide more information than scientists obtain using only their senses.

Scientists develop explanations using observations (evidence) and what they already know about the world (scientific knowledge).

Scientists make the results of their investigations public; they describe the investigations in ways that enable others to repeat the investigations.

Scientists review and ask questions about the results of other scientists' work.

Grades 5-8

Different kinds of questions suggest different kinds of scientific investigations.

Current scientific knowledge and understanding guide scientific investigations.

Mathematics is important in all aspects of scientific inquiry.

Technology used to gather data enhances accuracy and allows scientists to analyze and quantify results of investigations.

Scientific explanations emphasize evidence, have logically consistent arguments, and use scientific principles, models, and theories.

Science advances through legitimate skepticism.

Scientific investigations sometimes result in new ideas and phenomena for study, generate new methods or procedures for an investigation, or

develop new technologies to improve the collection of data.

Grades 9-12

Scientists usually inquire about how physical, living, or designed systems function.

Scientists conduct investigations for a wide variety of reasons.

Scientists rely on technology to enhance the gathering and manipulation of data.

Mathematics is essential in scientific inquiry.

Scientific explanations must adhere to criteria such as: a proposed explanation must be logically consistent; it must abide by the rules of evidence; it

must be open to questions an possible modification; and it must be based on historical and current scientific knowledge.

Results of scientific inquiry -- new knowledge and methods -- emerge from different types of investigations and public communication among

scientists.

Essential features of classroom

inquiry Learners are engaged by scientifically oriented

questions.

Learners give priority to evidence, which allows them to develop and evaluate explanations that address scientifically oriented questions.

Learners formulate explanations from evidence to address scientifically oriented questions.

Learners evaluate their explanations in light of alternative explanations, particularly those reflecting scientific understanding

Learners communicate and justify their proposed explanations.

Variations to classroom inquiry

More ---- Amount of Learner Self-Direction ---- Less

Less ---- Amount of direction from Teacher or Material ---- More

Full Inquiry ---------------- Partial Inquiry

Open Inquiry ---------------- Guided Inquiry

Variations to essential features

Some myths…

1. All science subject matter should be taught through inquiry.

2. True inquiry occurs only when students generate and pursue their own questions.

3. Inquiry teaching occurs easily though use of hands-on or kit-based instructional materials.

4. Student engagement in hands-on activities guarantees that inquiry teaching and learning are occurring.

5. Inquiry can be taught without attention to subject matter.

Common components shared by

instructional models Phase 1: Students engage with a scientific question, event, or

phenomenon. This connects with what they already know, creates

dissonance with their own ideas, and/or motivates them to learn

more.

Phase 2: Students explore ideas though hands-on experiences,

formulate and test hypotheses, solve problems, and create

explanations for what they observe.

Phase 3: Students analyze and interpret data, synthesize their ideas,

build models, and clarify concepts and explanations with teachers

and other sources of scientific knowledge.

Phase 4: Students extend their new understanding and abilities

and apply what they have learned to new situations.

Phase 5: Students, with their teachers, review and assess what they

have learned and how they have learned it.
