In order to give the laboratory-centered course a trial run and to compare it with a lecture-centered course it seemed necessary to the author that both courses should be taught and compared. The latter gave rise to the following hypotheses:

  1. Students in a laboratory-centered general chemistry course show more favorable attitudes toward chemistry than do students in a lecture-centered course.
  2. Students in a laboratory-centered course show as good a subject-matter mastery as students in a lecture-centered course.
