This final report summarizes an extensive evaluation of the COMP-LAB project, a course which integrates carefully defined classroom instruction with an autotutorial writing laboratory for teaching basic writing and rhetoric, particularly to students impaired by foreign language or nonstandard speech. Information on the project background and the development of procedures for its evaluation are presented. The major portion of the report discusses the actual results of the evaluation, also giving the students' and instructors' points of view, and includes information on the nature of the students involved in the lab and on the costs and benefits of such a program. The report concludes from this evaluation that the COMP-LAB course is superior to the traditional course, especially in improving student writing. (HTH)
