A two-phased research project sought to develop instructional sequences for computer-assisted technical training materials which would reduce student learning time. In Phase I, technical concepts embedded in training materials were subjected to Inscal Multidimensional Scaling to determine their complexity and relationships; the materials were then revised. Pictorial analogues of verbal materials and tests were developed and the added measures of 1) Cloze Comprehension, 2) Concept Cloze Comprehension, and 3) Post-Instructional Concept Similarity Ratings were used. Analysis of performance measures indicated that the Inscal technique aided the definition of information complexity of technical material, the development of sequences of concepts, and the creation of an index of inter-rater consensus. Parameter values selected for the Phase II experiment included: 1) determination of presentation rate; 2) selection of performance measures; 3) refinement of presentation and test modes; 4) selection of three instructional sequences; and 5) inclusion of individual difference measures to assess variance in student aptitude.
