Course Meeting Times

Direct student experience with physics as an experimental science is rare in introductory college courses. The accompanying labs are often peripheral to the course (little credit, little involvement); and have set-piece experiments, sometimes with computers, that give students very little more feeling of how things really work than lecture demos or homework problems (valuable as these are).
At MIT, starting in 1988, John King, Phylis and Philip Morrison, Tony French, and Peter Dourmashkin developed and taught two courses, Mechanics (8.01X) and Electricity & Magnetism (8.02X), in which experiments were central. For a 12-week course there are 8 to 10 experiments that are issued in kit form to student partnerships of two, along with instruments, all in two “Red Boxes” (small plastic toolboxes). Each student purchases (at cost) a tool kit with soldering iron, pliers, wire cutters and strippers, screw drivers, etc.
The partners meet to assemble and run the experiments in their living quarters, take and analyze data, and turn in their notebooks for comment; thus the experiments are part of homework, which also has a reduced number of conventional problems.
These experiments were made central to the course:
- By connecting them closely to the theoretical presentations in lectures and text
- By taking 25 minutes out of the weekly 150 to discuss the experiment of the week, how to assemble the apparatus, how to troubleshoot, how to take, analyze and present data
- By having homework and test problems related to the experiments
Note that the mechanics experiments involve electrical construction and measuring techniques, no more mysterious than a stopwatch or PC. But here a digital multi-meter is taken as an instrument to use; in the E&M experiments analog meters are not only used but also understood-students learn all about how they work.
Courses similar to these have been presented at Caltech, Harvard, and Ecole des Mines.
All necessary materials can be acquired from an online electronics supply source.
Besides the course syllabi and notes, and instructions for 12 basic constructions and experiments (Dourmashkin and King), there is a complete collection of 50 experiments (King, J. G., and A. P. French. Physics 8.01X and 8.02X Experiment Instructions. MIT Physics Department, 1998) that have been used at various times. Finally, there was a published book, ZAP!, designed to be used in conjunction with a version of these introductory physics courses taught at Caltech: Morrison, Philip, Phylis Morrison, and John King. Zap!: A Hands-on Introduction to Electricity & Magnetism. 1991. Preliminary ed. ISBN: 9780892784141.

There will be a total of 4 quizzes. They will be closed book, and calculators will not be necessary. Quizzes will typically include at least one question on the experiments and one question on lecture demos. Quizzes will account for 60% of the final grade. There is no final exam.
There will be twelve written homework’s (problem sets). Late homework’s will not receive credit.
The take home experiments are a crucial part of the 8.02X experience. Each partnership of two students will build and use 9 experiments. All experiments need to be demonstrated and checked off during lab hours. Experiment related questions will be asked at check-off and will be included on the problem sets, as well as in the quizzes. Early check-off of the experiments will be awarded bonus points. The detailed check-off and grading policy will be announced in class. A book with experiment information and instructions will be provided.
Registered students will be given access to Mastering Physics, an on-line tutorial and homework system. There will be a total of 10 Cybertutor assignments.
Note: OCW Users will not be able to access this material.
