Secondary Education and Teaching


The purpose of this study was to investigate the comparative effects CAD and manual drafting have on the effectiveness of teaching technical drawing techniques to secondary students. The problem of the study was to compare CAD and manual methods using the sectional view and auxiliary view techniques of Technical Drawing on second level Mechanical Drawing students.

The researcher, as the teacher, taught the concepts of the two technical drawing techniques, sectional view and auxiliary view drawings. During each section of the study, one group was assigned to complete drawings using the computer assisted drafting method and the other group used the manual tools and methods. The groups switched methods as the drawing technique changed from sectional views to auxiliary views.

An ANOVA was used to calculate data on the drawing tests, the written test, and on total time to complete drawings and the written test for the respective methods of each section. Based on the data obtained from this study, it can be concluded that both manual and CAD are acceptable methods of teaching sectional view and auxiliary view drawings.
