Advocates a field seminar program in which prospective earth science teachers, as well as other student participants, may earn college credits for taking part in field experiences. (CP)

Reports on an undergraduate earth science course for non-science majors structured around five-week minicourses. Evaluates student and teacher response to the program. (CP)

Provides an account of the way in which one small university has coped with limited funds and a small staff to provide laboratory activities for freshman physics courses. (CP)

Provides the outline of an introductory college-level physics course which combines astronomy, astrophysics, relativity and communications with a study of civilizations and the conditions necessary for life. Student comments and an informal evaluation of the course are included. (CP)

This article examines: (1) some difficulties associated with teacher interaction analyses, (2) well known teacher interaction scales, (3) current directions in research and practice in observation, and (4) special applications of teaching interaction analyses to the field of physics. (CP)
