Although basing instruction on learning trajectories (LTs) is often recommended, there is little direct evidence regarding the premise of a LT approach--that instruction should be presented (only) one LT level beyond a child's present level. We evaluated this hypothesis in the domain of early shape composition. One group of preschoolers, who were…

A correspondence exists between a simplified data collection method employing results from a post test for graphic skills in kinematics, and a rigourous validation method. Examination of test responses for discrepant instances yielded further information of value. Hierarchical patterns of learning and remembering are identical. (Author/CP)

A FINAL REPORT WAS MADE OF THE ACTIVITIES PURSUED IN PHASE 1 OF A 10-YEAR PROJECT DEALING WITH THE PSYCHOLOGICAL AND EDUCATIONAL FACTORS INVOLVED IN TRANSFER OF TRAINING. PHASE I CONSISTED OF A SURVEY OF THE EXISTENT DATA AND CONCEPTS OF TRANSFER OF TRAINING IN AN ATTEMPT (1) TO SUMMARIZE, INTEGRATE, CONSOLIDATE, AND INTERPRET RESEARCH FINDINGS…

TWO STRATEGIES FOR TEACHING MULTIPLE-DISCRIMINATION TASKS WERE REPORTED. THE "MULTIPLE CONCEPT" PRESENTS SIMPLE DESCRIPTIONS OF SEVERAL RELATED CONCEPTS AT THE BEGINNING OF INSTRUCTION. INCREASINGLY COMPLEX MATERIAL PERTAINING TO THESE CONCEPTS IS THEN GRADUALLY INTRODUCED. THE "SINGLE CONCEPT" PRESENTS ONE CONCEPT AT A TIME,…
