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
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
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
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
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
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
