An evaluation of curriculum materials (four publications) disseminated to Mississippi industrial arts teachers during the 1976-77 school year was conducted. Four questionnaires were prepared and mailed to all of the state's 242 industrial arts teachers. The objectives of the evaluation were to determine the following: (1) number of teachers using the materials in their programs; (2) amount of usage of the materials in terms of hours of instruction taught; (3) amount of usage of the materials in terms of number of students taught; (4) overall quality of the materials as rated on thirteen specific items; and (5) the extent that dissemination programs influence the use of Mississippi State University Research and Curriculum Unit materials. Based upon the findings, the following conclusions were drawn: (a) three out of four industrial arts teachers were using the materials in their programs; (b) the average number of hours taught per class with the materials was close to the suggested time for each publication; (c) a total of 9,708 students received instruction in industrial arts programs as a result of the materials; (d) in the opinion of the teachers, the overall quality of the material is high; and (e) the chances are greater that teachers who are presented the materials through dissemination programs will use the publication in their classes as compared to those who just receive the publications in the mail.
