1. Investigative Science Learning Environment ISLE Andrej Petek Adviser: prof. Gorazd Planinšič Coadviser: prof. Eguenia Etkina Ljubljana, dec. 2013

2. Table of contents Introduction Motivation for the development of ISLE ISLE cycle Other aspects of ISLE instruction Performance of ISLE students

3. 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 21 st century workplace

4. Key features Students 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

5. ISLE cycle

15. Multiple representations Sketches Force diagrams Motion diagrams Energy bar charts Field lines Ray diagrams Graphs Mathematical expressions

16. Final situation: Starting situation: Assumption: negligible air drag

17. Energy bar charts Observed system: Wile only Observed system: Wile and Earth

18. Assessment Summative Formative (feedback both to students and to the instructor with the subsequent revision of instrucion)

19. 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?

20. 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)

21. Summary Active participation of students in learning process Students gain procedural as well as declarative knowledge ISLE cycle Multiple representations Self-reflection ISLE improves physics instruction
