A freshman physics laboratory is being developed, in which an attempt has been made to eliminate as far as possible the type of experiment with detailed instructions, commonly known as the “cook-book” variety. The experiments fall into groups that form integrated sequences, e.g., “measurement,” “two-dimensional motion,” and “circuit elements.” Frequent reference is made back to the results found in earlier laboratory periods. Students are encouraged to devise their own experimental designs, within the framework of the equipment provided, which is kept simple enough for this to be practicable. While explicit instructions are rarely given, each laboratory exercise is accompanied by a number of leading questions that are intended to guide the student in deciding how to design and execute his experiment and interpret his results. Student reaction is favorable, but a significant amount of time must be devoted to training of the graduate teaching assistants who participate in the course.
