The 8 step procedure
1. Do the demonstration without graphs 2. Students record individual predictions 3. Small group discussions 4. Whole class discussion 5. Students record final prediction (collect) - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - 6. Do the demonstration with graphs 7. Discuss results with class 8. Extend results to analogous situations
The Original 5 ILDs
1. Human Motion - students walk d-t, v-t graphs 2. Motion with Carts - fan accelerates to/from 3. Newton’s 1 & 2 - cart pulled by falling mass 4. Newton’s 3rd - 2 force probes pull each other 5. Energy of a Cart - PE/KE moving up ramp
Additional ILD sheets
6. Collisions - equal/unequal masses engage in elastic & inelastic collisions 7. Harmonic motion - a mass hangs on a spring and oscillates up and down (KE, GPE, SPE)
ILDs recently developed
8. Sound - waveform of sounds 9. Light - reflection & refraction 10. Lenses - image formation 11. Magnetism - electromagnetism 12. Induction - in a coil 13. Potential/Energy - compare GPE & EP 14. Electric Fields - particles interacting
ILD 2004 Manual
Wiley has recently published all of these 14 ILDs and more in one volume Check the Wiley website for details
Research Results
Thornton & Sokoloff reported research showing the benefits of ILDs for conceptual learning
Research Results
Thornton & Sokoloff reported research showing the benefits of ILDs for conceptual learning Wittmann did extensive research on the benefits of ILDs & RealTime Physics. For ILDs, benefits only appear when the instructors closely follow the 8-point procedure in both spirit and letter
