Presentation Transcript

1. PHYS 160-309 1030-1120 Tuesdays Planetary Hall Room 220 with Dr. Harold A. Geller Office: Planetary Hall Room 233

2. Purpose of Recitations (change over 50 years) Original purpose Aid students in doing homework assignments Preparation for exams Aid in studying physics Aid in understanding physics concepts Morphed or accidental purpose Give students more work for course Give a separate grade for more work Further careers of some individuals in physics education research Add to cost of taking course to the benefit of publishers

3. Quick Tips for Homework and Exams Be confident and prepared Read test instructions carefully Read each question carefully and read each choice before you record your answer Budget your examination/homework time Use your reasoning skills Use reference tables/equations as allowed (and needed) Don t be afraid to guess Follow the GMU honor code

4. Quick Tips for Solving Numerical Problems List the appropriate equations Substitute values and units (dimensional analysis) into the equations Display the answer clearly using the appropriate units and to the correct number of significant figures Remember that if the answer is a vector quantity, you need to include the direction

5. Quick Tips for Graphical Questions Graphs should have titles Plot independent variable on the x-axis Label both axes with appropriate variables and units Divide the axes so the data ranges fill the graph as nearly as possible Plot all data points accurately Draw best fist line carefully with a straightedge Best fits should pass through origin only if data warrant it If calculating slope from graph, use best fit line not individual points

6. Quick Tips for Supporting Diagrams Draw diagrams neatly and label them clearly Draw vectors to scale and in the correct direction Check to see if you are provided a scale to use for your vectors Use straightedge and protractor to display vectors accurately

7. Quick Tips for Extended Response Questions Use complete, clear sentences that are logical Use correct physics in your explanations Print clearly and of reasonable size Do not use sentence fragments or incomplete sentences
