We need Hands-On and Minds-On Physics Education! Students need to be trained to think like scientists of tomorrow A balance of theory and analysis is required Courtesy http://www.clipartoday.com

Biggest Challenges in Physics Education “Physics is for smart students” “Physics involves a lot of math” “Physics is not useful in real life” “Physics involves a lot of theory” -Conceptual Understanding is Key in Physics -Our Students Today are Teachers Tomorrow! -Need to Address these Challenges Now!

Non-Science Majors Conceptual Physics (No Algebra or Calculus) Focus on Concepts Plenty of Opportunities for Hands-On Learning Science, Not-Physics Majors Physics to Introduce Analytical Thinking Algebra but no Calculus Plenty of Hands-On Learning Physics Majors Future Scientists or School Teachers Very Motivated Algebra and Calculus Based Physics Plenty of Hands-On Labs and Activities

Hands-On and Minds-On Learning: Example 1 Teaching and Learning Circular Motion Using Applets http://www.mhhe.com/physsci/physical/giambattista/banked_curve/banked_curve.html

Coefficient of friction Student Question: Keep the angle of inclination of the track constant Determine the speed or speeds at which the car crashes, for different coefficients of friction Coefficient of friction Speed at which car crashes (m/s) 1.5 1.2 0.9 0.6 0.3

Thinking Physics High speeds: Friction acts to the bottom of the incline

Thinking Physics Low speeds: Friction acts to the top of the incline
