Although there was an increase in the proportion of students using the logical principle of exclusion" from grades 7 to 9 to 12, there was little relationship with IQ and socio-economic measures. (AL)

One aspect of Jean Piaget's theory of intellectual development is presented and its implications for designing and using homework problems is discussed. Suggested is a way in which homework problems can be used to provide students an opportunity for self-regulation. Also discussed are the deficiencies of typical homework problems and examples are…

Piaget's developmental theory is discussed and several research findings that involve Piaget's theories are reported. The understanding of reasoning patterns is presented as a means for the science teacher to identify the conceptual emphasis and demands of the subject matter and to help students develop more advanced reasoning patterns than they…

Psychological equilibration (internal mental process by which individuals develop intellectually) is discussed in terms of its origin in the biological theory of evolution and in the thinking of Jean Piaget. The importance of equilibration theory for biology instruction is then considered. (Author/JN)

Reported is an Aptitude Treatment Instruction (ATI) Study designed to evaluate the aptitude of verbal comprehension in terms of two unitary complex science diagram types: a single complex block word diagram and a single complex picture word diagram.. ATI theory and research indicate that different effective instructional treatments tend to help…

Discusses a study that examined which reasoning patterns are necessary for success in high school chemistry. Based on student (N=170) scores from the "Classroom Test of Formal Reasoning," it was revealed that students who use formal reasoning patterns are capable of greater achievement in chemistry. (ML)

Examined the effects of Piagetian-like tasks' characteristics on the performance of those tasks by different age group students. Indicates the method of task presentation had an effect only on young students' performance, while numerical content had an effect on the majority of students in all grades. (Author/CW)

Examined influence of teaching methods on content achievement of concrete and formal concepts by students differing in level of operational thought and influence of concrete/formal teaching on the intellectural development of students (N=86 grade 9-10 biology students). Methodology, results, conclusions, and implications are discussed. (Author/JN)

Examines thought processes closely linked with intellectual development and transcending boundaries of many disciplines. Among the topics discussed are: nonuniform change without calculus; discrimination between observation and inference; asking one's own questions; hypothetico-deductive reasoning; and types of knowledge. (JM)

Developmental patterns in one mode of formal reasoning (probabilistic reasoning) were examined in this research study, specifically: (1) to determine if developmental patterns of probabilistic reasoning could be confirmed using a large, diverse sample of subjects, and if they could be similar despite variations in the complexity of the reasoning…

This document presents research studies/findings and provides a developing point of view on adolescent thought. The first chapter discusses the nature and definitions of thinking. The second and third chapters discuss frameworks for adolescent thought (focusing on the Gestalt school, Geneva school, and accelerated learning) and survey studies on…

A model for the development of scientific reasoning in adolescents was formulated largely upon the basis of Piagetian theory. Included as potential determinants of scientific reasoning were experience, age, locus of control, field independence-dependence (FID), rigidity/flexibility, intelligence quotient (IQ), and sex. Causal relationships between…

Outlines the constructivist model of knowledge and describes how this model relates to Piaget's theory of intellectual development. Contrasts the constructivist model with the traditional views of knowledge. Discusses how this model can help explain some of the things that happen in chemistry classrooms. (TW)
