This exploratory study determined whether a mathematical model of mastery learning provided a good fit for achievement data obtained from student progress in an introductory, college-level astronomy course for nonmajors. Results provide positive but not compelling evidence that the model of mastery learning is correct. (JN)

Describes an introductory astronomy course for undergraduate students in which students use three-dimensional (3-D) modeling tools to model the solar system and develop rich understandings of astronomical phenomena. Indicates that 3-D modeling can be used effectively in regular undergraduate university courses as a tool to develop understandings…

Investigates the effect of three models of teaching college astronomy on knowledge acquisition, based on the principles of kinetic structure analysis and the psychological concept of mass versus distributed practice. Results indicate that distributed integration is better than nondistributed integration in teaching certain fields in astronomy. (HM)

Three variations of computer assisted instruction feedback were used with college astronomy students. On only one measure, a posttest, did subjects' achievement by treatments differ significantly. Significant differences in attitudes according to treatment group were not observed. (CP)

This study compares inservice (n=30) and preservice (n=30) earth and space science teachers on general mental abilities, content knowledge, Gagnean levels of content knowledge, and procedural knowledge in solving earth and space science problems. Results support Norman's theory of learning that inservice teachers function at the tuning mode of…
