Introduction

Motivation for the development of ISLE

ISLE cycle

Other aspects of ISLE instruction

Performance of ISLE students

Why use ISLE method of teaching?

Improve student learning of physics normative knowledge

Help students experience science process as a part of their learning physics not a short time add-on

Help stuudents prepare for the demands of the 21st century workplace

Key featuresStudents actively construct their knoweldge by:

Observing simple experiments to develop models

Designing new experiments to test models

Reconciling their prior ideas and new models

Representing ideas (experiments and models) in multiple ways

Engaging in repeated self-reflection

Solving real life problems as application of new knoweldge

ISLE cycle

Multiple representationsSketches

Force diagrams

Motion diagrams

Energy bar charts

Field lines

Ray diagrams

Graphs

Mathematical expressions

Final situation:

Starting situation:

Assumption: negligible air drag

Energy bar charts

Observed system:

Wile only

Observed system:

Wile and Earth

Assessment

Summative

Formative (feedback both to students and to the instructor with the subsequent revision of instrucion)

Weekly reports

What did I learn this week?

How did I learn it?

What remained unclear?

If I were the professor, what questions would I ask to find out if my students understood the material?

Do students learn physics through ISLE?

FCI (Force concept inventory)

CSEM (Conceptual survey of electricity and magnetism)

Traditional instruction (FCI): g ≈ 0.2 - 0.3

Ohio State University (g = 0.56)

California State University Chico (g = 0.45)

g= posttest score− pretest score100− pretest score

Summary Active participation of students in learning
