dc.description.abstractThis study was an experimental investigation of image linearity in instructional films on metallic inert gas welding. Two null hypotheses were tested. The first assumed no differences in mean gains on achievement tests among groups receiving instruction classified as control, linear image, and nonlinear image. The second hypothesis assumed no differences in the degree of manipulative skill development among the three groups. An experimental image format and a traditional format were developed for presenting the same context in different screen images to test the variable of linearity. Context in the experimental series was presented in a cumulative and simultaneous viewing order with animated images supplementing real-life context. The traditional or linear format presented a single image with related subject matter shown in consecutive and sequential viewing order. Three units of instruction on metallic inert gas welding were selected by tabulating questionnaire returns from various educational institutions. The three units were the basis for subject matter in producing a silent, sixteen millimeter, color film on each unit. An achievement test was developed on each unit and combined to produce the pretest. Ability to apply manipulative instruction was evaluated with weld coupon tensile and ductility tests. The experiment was conducted using ninety students in five classes of beginning welding taught by two instructors..en
