A study was undertaken at Glendale Community College, in California, to determine the effectiveness of a 2-week summer macroeconomics course. To gather data, the instructor maintained a diary of topics covered and problems encountered, surveyed all 20 students upon completion of the class regarding their experiences and satisfaction, and compared outcomes on standard unit exams for three 15-week classes offered in spring 1995. Study results included the following: (1) the 2-week course was perceived as more stressful than 15-week courses by nearly 60% of the students and imposed severe time burdens on all students; (2) student satisfaction declined upon taking the course, with 45% indicating that they would not take the course again; (3) 45% of the students thought that they would have achieved better mastery of course material in a 15-week course; and (4) while summer students performed better than spring students on unit tests from the first half of the course involving simple recall of information, they performed worse on unit tests from the second half involving comprehension, application, and analysis. As a result of the findings, it was recommended that the 2-week format be abandoned for economics classes. Appendixes include the course syllabus, the instructor's diary, the student survey questionnaire with tabled responses, and tables of the statistical analysis of unit exams. (TGI)
