Abstract:

An experimental comparison was made between fixed sequence FS and branching versions of two CAI lessons in basic electronics. The FS versions provided minimum opportunities for branching. In contrast, the branching versions utilized a combination of branching applications, including bypassing of initial instruction, remedial branching, dual-control practice, and optional review. Branching produced substantial savings in training time. Average times for the branching versions were 30 to 66 smaller than for the FS version. Branching was equally effective for students of high and low aptitude. Scatter plots and regression analysis indicated that average time savings were the same at all aptitude levels sampled. The number of branch frames taken was independent of aptitude. Branching increased the extent of individual differences in training time. Author
