Twin studies find ~20% of the variance in achievement in public examinations taken at age 16 in the United Kingdom can be explained by experiences not shared within families. Nonshared environmental (NSE) influences, including measurement error, explain why monozygotic (MZ) twins differ from each other. Such influences work independently of…

A personalized e-learning service provides learning content to fit learners' individual differences. Learning achievements are influenced by cognitive as well as non-cognitive factors such as mood, motivation, interest, and personal styles. This paper proposes the Learning Caution Indexes (LCI) to detect aberrant learning patterns. The philosophy…

The study makes use of Rotter's (1966) hypothesis that there are consistent individual differences between people who believe in the internal control of reinforcement and those who believe in the external control of reinforcement. Students who are "internals" will believe that their behavior controls academic successes and failures and may,…

Single-case analyses were conducted of the dosage and time-course effects of methylphenidate on disruptive classroom behavior, math and reading performance, and social engagement. In contrast to previous studies, clear individual differences were demonstrated: across children; across academic, behavioral, and social domains of functioning; for…

College students experiencing academic difficulties are a major concern to universities. Research has indicated that many underachievers display certain identifiable electroencephalogram (EEG) characteristics. Unlike achieving students, underachievers often exhibit little EEG arousal during normally motivating tasks. These findings suggest that…

Problem-based learning (PBL) as a new instructional method is becoming increasingly popular. PBL is hypothesized to have a number of advantages for learning because it applies insights from cognitive learning theory and it fosters a lifelong learning strategy. As in all learning programs there are individual differences between students. This…

This study was concerned with investigating patterns of verbal interaction of teachers and students who were matched and mismatched in field dependent and field independent cognitive styles. The first objective was to answer the general research question: Is there a difference in the patterns of dyadic classroom interaction when the teacher and…

THE RELATIVE EFFECTIVENESS OF ALTERNATE APPROACHES TOWARD INDIVIDUALIZATION OF FIXED-PACED PROGRAMED INSTRUCTION WAS ASSESSED. THIS REPRESENTED THE THIRD IN A SERIES OF THREE STUDIES CONCERNING THE RELATIONSHIP BETWEEN PACING MODE AND BEHAVIOR. (REFER TO ACCESSION NUMBERS ED 003 199, ED 003 200, AND ED 003 202 FOR ADDITIONAL INFORMATION ON THIS…

This is the final report on a three year project designed to investigate the development of problem-solving strategies in elementary school children. In this project the personality of the child as it is reflected in problem solving style is examined. The hybothesis that reflective children are more competent problem solvers than impulsive…
