Instructions: 1. Use a phone or camera to record yourself explaining the correct process used to answer the questions you answered incorrectly. This can be done at home, in Room 222, or with any other whiteboard available. If you have multiple videos, compile them into a single video; several freeware programs can do this effectively. 2. Title the video with your last name and the test number. You can email this file, share it on Google drive, or bring-in the file on a thumb drive. 3. When filming, set the camera down so that it is stationary and present the solution as if you were teaching a class. 4. Begin each problem by stating what the number is and what part or parts of that number are being corrected. Turn-in the graded test itself when you have submitted the corresponding corrections. 5. Limit the total time of filming to ten minutes or less for each test. 6. Use the time efficiently. Don't spend part of the time just writing and drawing on the board; have the diagrams and equations already drawn. Explain the physics, not the math. 7. If your corrections are done well, you will receive two-thirds of the points lost on the original exam. For example, if you corrected a test with an original grade of 70%, your final grade could rise to 90%. 8. Again, explain each solution as if you were teaching someone. If you only write or recite the correct solution, it doesn't demonstrate any understanding and won't receive any credit. 9. Another option is to type the explanation for every solution and save this file under your name and the exam name. Email this file by the due-date. Written corrections can receive up to 50% of the original points deducted.
