INQUIRY: TO TEACH CONTENT AND PROCESSi-STEM Presentation

Louis Nadelson, Ph.D.

Summer 2010

PRESENTATION GOALS

• Define “inquiry-based instructional practices”

• Explain why they should be used to teach STEM

• What are the roles of the teacher and what are the roles of the students

CHALLENGE WITH INQUIRY

• The challenge with defining inquiry is the reality that the same term can mean different things to people (Chinn & Malholtra, 2002). For example, Abd-El-Khalick and colleagues (2004) contend that many interpret “inquiry” to be representative of good science instruction and yet, inquiry can be more specifically defined and identified as an approach to scientifically investigating phenomena.

RESEARCH

WHAT IS INQUIRY?The National Research Council (1996) defines inquiry as:

The diverse ways in which scientists study the natural world and propose explanations based on the evidence derived from their work. Scientific inquiry also refers to the activities through which students develop knowledge and understanding of scientific ideas, as well as an understanding of how scientists study the natural world.

IS INQUIRY EFFECTIVE FOR LEARNING?• In their review of literature reporting

investigations of middle school inquiry-based science from 1990 to 2008, Nadelson and Williams (Under Review) found that there inquiry based learning leads to increases in both science achievement and knowledge of science processes – with the largest gains reported for low-academic ability learners

DISCONNECT WITH TEACHING INQUIRY• We expect teachers to teach using

inquiry practices in STEM and yet very few teachers have had authentic inquiry experiences upon which to base their practice (Southerland, Nadelson, Sowell, Under Review)

• However, guided or scaffolded higher levels of inquiry may be very effectively used with novice learners (Nadelson, 2009)

LEARNING – IN BRIEF…

• Learning involves the acquisition and integration of new information and is based on prior knowledge

• The goal of learning is becoming an “expert”

• Learning frequently requires correcting naïve or false conceptions about a complex topic

• Learning is required to become a member of a community of practice

LEARNER ROLES IN INQUIRY INSTRUCTION

• Learners:

– engage in scientifically oriented questions – PRIOR KNOWLEDGE.

– give priority to evidence, which allows them to evaluate explanations that address scientific questions - REFLECTION.

– formulate explanations from evidence to address scientifically oriented questions – APPLICATION.

– evaluate their explanations in light of alternative explanations, particularly those reflecting scientific understanding – EVALUATION.

– communicate and justify their proposed explanations – ELABORATION.

AN INQUIRY ACTIVITY

• Paper helicopters– Build the helicopter

– Does it work? How?

• Make at least TWO variations to the design– What happened?

– Why?

• Conclude and compare results

LEARNER ROLES IN INQUIRY INSTRUCTION

"Wow! If we learn from our mistakes, I ought to be a genius by now."

EXPECTED BENEFITS OF INQUIRY

• Students doing science

• Applying practiced techniques to new situations

• Understanding of “why”

• Student interest/motivation

• Students taking part in their learning

• Students learning they have valuable thoughts and ideas

SCIENCE THE OLD-FASHIONED WAY

• Students read aloud from texts.

• Students memorize long lists.

• Content presented in lectures.

• Tests require rote recall.

• Lab experiences merely confirm what students have read or been told.

• Goal of assessment is to grade students.

SCIENCE THE OLD-FASHIONED WAY

SCAFFOLDING INQUIRY• There is a need to investigate the effectiveness

of different approaches of inquiry to determine if there are more successful ways at increasing student learning of science and understanding of scientific research.

• It seems intuitive that students should learn more about science by doing science, but how they do science requires attending to learner needs, experience, and capabilities

INQUIRY: AN APPROACH TO TEACHING AND LEARNING

Questions posed by the students OR teacher.

Student OR teacher provide methodology.Students are given data OR collect and

analyze their own data.Students use evidence to build an

explanation (with OR without guidance).Students communicate explanations using

their own formats, OR formats and procedures that have been given to them.

Students evaluated the credibility and validity of outcomes.

RESEARCH SHOWS:

• In a recent research project examining undergraduate laboratory texts that the publishers purported contained inquiry based exercises that over 90% were below classified below “Level 1 inquiry”

INQUIRY LEARNING TAKES TIME

• Provide opportunity for students to first grapple with information relevant to a topic to create a meaningful time for telling.

“. . . learning cannot be rushed; the complex cognitive activity of information

integration requires time.”

CRITERIA FOR CLASSROOM INQUIRY

The curriculum includes:involvement in hands-on activities or

simulationsformulation of questionsmaking and checking predictionsdesigning/carrying out investigationscollecting, analyzing, and explaining datamanipulating variablesreporting results and comparing them with

accepted factsdeveloping scientific reasoning skillsstimulating to increase engagement in learning

Inquiry

Conceptual emphasis

INQUIRY, PROBLEM BASE LEARNING AND PROJECT BASED LEARNING

• Meaningful Activity• Engage students in problems that are

designed to be realistic, intriguing, and relevant to the field of study.

• Provide context and stimulus for knowledge-building and critical thinking.

• Situated Learning • Creates an environment that permits students

to work on the kinds of problems that professionals encounter and to use the perspectives, the knowledge, and the skills that professionals use in attempting to solve them

• Changed Role of the Instructor• Instructors act as metacognitive coaches

throughout the inquiry process. • They coach - giving students guidance as

needed, but encouraging student independence in goal setting and decision-making.

• Give EXPLICIT and DETAILED expectations and facilitate REFELCTION

INQUIRY STRUCTURE FOR TEACHING

• Open-ended Generative Tasks

• Offer ill-structured, open-ended problem for which there is no prescribed approach or solution.

• Promote intentional learning by requiring student to generate their own questions, plans, and goals.

• Collaborative Decision-making and Problem-solving

• Require students to work together in their problem solving and product development.

• Students collaborate with each other and with more knowledgeable individuals who model expert behaviors and lend assistance as students try out skills on their own.  

INQUIRY STRUCTURE FOR TEACHING

INQUIRY STRUCTURE FOR TEACHING

It increases the likelihood of TRANSFER, a primary consideration in education.

The literature on transfer suggests that transferable learning experiences occur in an environment characterized by:

• Meaningful activity

• Expert guidance

• Knowledge-building collaboration

INQUIRY STRUCTURE FOR TEACHING

It is engaging and, therefore, motivating.

Berliner (1992) notes:

Intertwined with the cognitive components associated with projects are the motivational components inherent in projects. These include the fact that projects teach students to be mastery-oriented, not ability-oriented; they teach students to be learning-oriented rather than performance-oriented; and they teach students to be task-involved rather than ego-involved…When there is some degree of choice for the students, project-based methods motivate students more than any other teaching method I know about.

WHY USE INQUIRY IN LEARNING?

INQUIRY LEARNING FOR LIFE

• Case-based learning making schooling relevant to the workplace, careers and authentic research activities

• Most effective transfer comes from a balance of specific examples and general principles.

School should be less about preparation for life and more like life itself.

- John Dewey

CLOSING THOUGHTS

– Inquiry and problem based learning is a great way to get students to think about how science works and how to think like a scientist – this must be taught explicitly and reflectively if students are going to learn the concepts and processes….

“The world is but a school of inquiry.”

-  Michel de Montaigne (1533-1592)
