THREE MEASURES OF LEARNING RATE WERE EXPLORED--(1) NUMBER OF UNITS COMPLETED PER YEAR, (2) TIME TO COMPLETE GIVEN UNITS, AND (3) AMOUNT OF CONTENT MASTERED PER DAY. THE SUPPOSITION WAS THAT THESE MEASURES COULD BE USED TO PROVIDE ESTIMATES OF INDIVIDUAL PROGRESS IN THE ELEMENTARY CLASSROOM ENVIRONMENT. ONLY ONE OF THESE MEASURES (AMOUNT OF CONTENT MASTERED PER DAY) SHOWED MINOR DEGREES OF CONSISTENCY OVER DIFFERENT UNITS OF INSTRUCTION, AND FINDINGS OF THE STUDY SUGGESTED THAT LEARNING RATE WAS NOT A GENERAL CHARACTERISTIC OF THE LEARNER. IT WAS TENTATIVELY CONCLUDED THAT RATE OF LEARNING IS SPECIFIC TO THE LEARNING TASK AND IS NOT A GENERAL PARAMETER THAT APPLIES TO ALL LEARNING FACTORS. RELATED REPORTS ARE ED 010 205 THROUGH ED 010 211 AND ED 010 519 THROUGH ED 010 523. (GC)
