East High School's Senior Seminar, a program which allowed groups of senior students to work in the natural environment of the activities or subjects being studied, was evaluated in 1973 by the following indicators: an attitude assessment and appraisal of the program by staff members, parents, and students; a follow-up survey of participants' post-high school status; a cost assessment; student retention data; selected descriptive data of participants; and narrative summary descriptions of the various Seminar learning modules. The study sample included a treatment group of 114 students enrolled in the Seminar and a control group of 114 students randomly selected from senior students. Data indicated: (1) many students and staff members felt that certain specific aims were realized; (2) present reporting, which consisted largely of narrative descriptions, student comments and reactions, logistic requirements, and suggested changes, seemed inadequate for program evaluation purposes; (3) the Seminar involved appreciable cost in additional staff involvement and effort; (4) certain instructional problems emerged; (5) the information as presented created difficulties in making judgments concerning instructional justification for the various modules, the degree of curricular balance, and the logic of sequence; and (6) the organization and administration of the Seminar appeared to be well done.
