This four-part report examines earth and space science education as revealed in the findings of a study, in which a literature review, an analysis of curriculum data, and a survey of science instructors were undertaken to explore science instruction at two-year institutions. Part I discusses the difficulties encountered in developing earth and space science curricula relevant to diverse student needs, and then analyzes the earth and space science offerings listed in 175 college catalogs and class schedules. Part II explores earth and space science instructional techniques, emphasizing individualized instruction in investigative laboratories, and then discusses class size, instructional mode, use of class time, instructional materials, grading practices, and course competencies and goals as revealed in a survey of 46 earth and space science instructors. Part III provides a profile of these instructors and discusses teacher satisfaction with course materials, support services, and working conditions. Part IV presents summary conclusions pointing out an increased awareness of the needs of non-transfer students in earth and space science curriculum planning. The report concludes with a list of recommendations and a lengthy bibliography. (JP)
