The South Carolina Office of Vocational Education directed the development of a set of curriculum materials for industrial sewing courses as a resource tool for South Carolina teachers. The materials consist of 20 individualized self-instructional modules, a glossary of terms, and a teacher guide. During the 1981-82 school year, the Research Coordinating Unit in conjunction with the Curriculum Development Section conducted a field test study to determine the accuracy and usefulness of the materials. During the field test, a control group design was used in which student achievement in 11 implementing classrooms (experimental group) was compared to student achievement in 11 classes that did not use the materials (control group). At the start of each semester, before instruction began, a pretest covering content that was to be taught was administered, and a posttest was administered at the end of each semester. Analysis of the data gathered by means of pre- and postachievement tests provides strong evidence that the materials are effective in promoting student learning. In spite of an initial disadvantage with respect to entry knowledge, the experimental group obtained higher posttest mean scores, and in most cases the differences between the mean scores in the two groups were significant. It was recommended that particular attention be paid to suggested revisions in those modules for which the posttest scores were not significantly higher in favor of the experimental group. Even without revisions, however, the data indicate that students taught through the modules do achieve higher scores following instruction; therefore, distribution of these materials should provide a useful resource for teachers of industrial sewing in the state.
