  1. How Technology Can Help Your Students Build a Deeper Understanding of the Subject and Enjoy Learning Physics By Dr. Marina Milner-Bolotin Department of Physics and Astronomy University of British Columbia

  2. You cannot teach a man anything, you can only help him to find it within himself. Galileo Galilei

  3. Inquiry-Based Physics Teaching Observational experiments Physical model Prediction IF-THEN Unsuccessful Testing Experiment Successful Applications: Problem solving, everyday life uses, new predictions

  4. Enhanced Experiments MBL Video Problem Solving Visualization Simulations WWW Dialogue Beyond the Classroom Interactive Lessons Lectures Technology – What is it Good for? Is it all? What else?

  5. Physics Problem Data-Bases • Mastering Physics (Free with Knight Textbook purchase – or $28 per semester per student): www.masteringphysics.com • The University of TX Database – Free • Database (The Department and the students pay) www.webassign.com • Many other databases – some are free

  14. Online Resources - ActivPhysics Physics problem solving: simulations, advice, strategies, graphs, diagrams, charts, interactive problems…

  15. e1 - i1 R1 - i3 R3 = 0 e2 - i2 R2 - i3 R3 = 0 i1 + i2 = i3 i1 i2 i3 R1 R2 R3 e1 e2 Technology and Multiple Representations ActivPhysics helps students create and connect different representations

  16. ActivPhysics Students visualize a problem, build energy bar charts, solve it, make and test predictions…

  17. Peer Response Systems • Systems which allow students answer multiple choice questions and transmit their answer to instructor’s computer • The answers can be displayed during the lesson and analyzed later • There are many different systems available • PRS – EduCue – Addison Wesley http://www.aw-bc.com/catalog/academic/product/0,1144,0321267354-DS,00.html

  18. Peer Response System

  19. Interactive Lectures – Using PRS A sample starts with 1000 radioactive atoms. How many half-lives have elapsed when 750 atoms have decayed? 1. 0.25 2. 0.75 3. 1.5 4. 2.0 5. 2.5

  20. Assume the rolling friction is very small Both men pick up the barrels with const speed PRS: Who Does More Work? • Bob • Joe • Both did the same amount of work

  21. PRS: Applying Gauss’s Law These are two-dimensional cross sections through three-dimensional closed spheres and a cube. Rank order, from largest to smallest, the electric fluxes Fa to Fe through surfaces a to e. 1. Φa > Φc > Φb > Φd > Φe 2. Φb = Φe > Φa = Φc = Φd 3. Φe > Φd > Φb > Φc > Φa 4. Φb > Φa > Φc > Φe > Φd 5. Φd = Φe > Φc > Φa = Φb

  22. Immediate Feedback: PRS Results Instructor and students get immediate feedback on the material comprehension. Large lecture becomes interactive

  23. Enhanced Experimentation - MBL Using available equipment, design an experiment which will test the model of 1-D motion Exploring the meaning of the area and slopes of graphs in 1-D Kinematics

  24. Enhanced Experimentation - Video

  25. Dialogue Beyond the Classroom • Discussion on problem solving via the interactive software – MP, WebAssign, WebCT, Discussion Boards, etc. • Getting immediate feedback on problem solving • Experimenting at home with the real data collected during the class time

  26. Technology and Physics Teaching Technology: • Is a tool and its effectiveness depends on how you use it • Doesn’t replace a teacher, but it opens new opportunities • Helps students to learn interactively outside of the classroom • Provides opportunities for more effective data analysis (video experiments, MBL, data analysis in Excel, Graphical Analysis)

  27.
