The findings and conclusions of a study of curriculum and instruction in two-year college social science, science, and science-related technology programs are summarized in three sections. The first selects from 1977-1978 curriculum data which were gathered from catalogs and class schedules of a representative national sample of 175 two-year colleges. Focus is placed on enrollments, and the availability and types of courses for transfer and occupational students, non-science majors, and students in developmental programs, revealing many introductory courses, few remedial courses, and an overall emphasis on serving students already disposed to the sciences. The second section deals with the courses themselves, based upon the results of an instructor survey mailed to 1,275 science and social science faculty members. Selected findings related to various subject areas are provided in terms of numbers of class sections, average class enrollments and completions, course level and objectives, use of instructional media and class activities, grading and examination practices, and instructor characteristics. Traditional teaching methods were found to predominate. The final section reviews the major findings and makes recommendations, stressing the role of the community college in improving science and social science literacy. The instructor survey instrument and responses are appended. (DR)
