This document presents a discussion of several dependent variables related to the topic of student choice of subject matter within specified courses. The dependent variables discussed are: attitudes, personality, pacing, achievement, future choices, and varied instructional outputs. Personality has never been used as a dependent variable in any research and therefore is only suggested as a possibility for future research, as are the variables of future choices and instructional outputs. Achievement, as might be expected, is mixed with regard to experimental and control groups and no positive statement can be made either way. However, research has been conducted using student attitudes toward and student pacing of work. Student attitudes are more often positive and least often negative if the students are given choices of coursework. In experiments concerning pacing, it has been proven that students, given a certain amount of work to be completed in a specified amount of time, are able to pace themselves to complete that work. A list of references is included. (HS)
