Discussions and studies carried out by students enrolled in a year-long economics curriculum seminar are reported. The seminar was organized to study and make recommendations to an economics department about changing the content and teaching of principles of economics courses at a State university. Thirteen students, masters candidates-teaching assistants or senior majors, enrolled in the course. The class activities are chronicled to give an understanding of how the seminar operated and to show how ideas for change developed and progressed during the year. The main body of the report contains eight of the student papers written for the seminar which form a fairly comprehensive study of the principles course. The papers include four empirical investigations of instruction in the principles courses, two analyses of the value and content of principles texts and programmed instruction, and two critiques of the content selection of the principles of economics. The final section reprints general recommendations submitted by students as well as the author's reflections about the recommendations and the course. (Author/KSM)
