This research hypothesized that preformal-operational children (before age 11) can improve their ability to write persuasive essays at an age earlier than Jean Piaget's developmental stage model would predict. A Vygotskian social interactionist approach, which claims that adult intervention can help children achieve what may have seemed beyond…

Physical and Earth Science AB, a required senior high school course in the Los Angeles Unified School District, uses an investigative approach for developing scientific understanding and attitudes for students. Contents include: (1) summary of representative objectives; (2) teacher responsibilities; (3) the agenda; (4) guidelines for assignment of…

Describes a study designed to determine if college students' success in writing computer programs is related to level of cognitive development as described by Piaget, verbal ability, and mathematics reasoning. Regression analysis showed that level of cognitive development, when combined with verbal reasoning, is linearly predictive of programming…

Discusses a study that examined the role of four cognitive factors (formal reasoning ability, prior knowledge, field dependence/independence, and memory capacity) on achievement in chemistry as measured by tests of lab application, chemical calculations, and content knowledge. Reports the significance of prior knowledge and formal reasoning…

Reports on a study designed to determine the effectiveness of two video programs with an audience of varied ages, grade levels, and developmental levels. Indicates that a significant difference was found between concrete, transitional, and formal operational students on pretest scores and developmental levels and results on the posttest. (RT)

Investigated were gender-related differences in the relationship between the development of formal reasoning skills and learning interests during the early adolescent stage. Results indicated that adolescent boys appeared to develop patterns of formal reasoning before their female classmates. Differences in subject preferences were also found. (CW)

Investigates gender differences and the role of spatial visualization in problem solving in high school geometry. Reports that, whereas males and females differed in spatial visualization and in their performance, they did not differ in logical reasoning ability or in their use of geometric problem-solving strategies.

Psychometric information was obtained on the Longeot test, which measures aspects of formal thinking, from a sample of 884 high school science students in India taking a Hindi version of the test. The test version appears valid for these students and may be used to classify subjects into Piagetian developmental levels. (SLD)

This book describes the Reflective Judgment Model (RJM) and provides a comprehensive review of the research on it and the Reflective Judgment Interview (RJI). Chapter 1 defines reflective judgment as an often neglected aspect of critical thinking. Chapter 2 discusses stage-related assumptions that underlie RJM and relates RJM to current work in…

This paper describes a study designed to investigate the development of scientific reasoning or logical thinking patterns of South Korean secodary school students. The scientific reasoning or logical thinking patterns were categorized into patterns of logic such as seriation, combinations, proportion, control of variables, probability, and…

Analogies and examples from student's experiences are frequently cited as important to teaching conceptual material. This study was conducted in order to explore the effectiveness of an analogical teaching technique, which uses a connected sequence of "bridging" analogies, compared with a more standard teaching-by-example technique. The…

A teaching procedure and a curriculum construction model known as the learning cycle is described in this paper and research findings are discussed. Questions investigated include: (1) would students achieve more content understanding if taught with the learning cycle or exposition?; (2) would more content retention be evident if measurements were…

Effective teaching strategies must be developed to help students bridge the gap between concrete operational thinking and full formal thinking in the content areas. Reading for meaning requires readers to categorize subjects, recognize relationships, develop and maintain a sequence of thought, recognize and understand inferences, and draw…

W. M. Gray's "How is Your Logic?" a Piagetian-based, group-administered written test of cognitive development, and B. Leadbeater's Livian Wars Task, a formal operations-based, written, social-cognition problem were given to 348 college undergraduate and graduate students to investigate the impact of chronological age and amount of formal…

Reviewed are recent studies of the cognitive development of Chinese children. The discussion identifies: (1) systematic studies of children's cognitive development; (2) studies on the development of thinking; (3) studies of memory development; and (4) studies on the influences of various national cultures and education on the development of…
