When doing spring planting activities, what does a teacher do while waiting for the plants to grow? This waiting time is a golden opportunity to explore another side of gardening--the creatures that make it all possible. Insects are an integral part of everyday world, having existed for over 300 million years; they are the most common animal on…

The purpose of this study was to explore the relationship of learner characteristics and preservice teachers' views of nature of science (NOS) prior to formal instruction. Learner characteristics investigated included metacognitive awareness, self-efficacy, attitudes toward science teaching, Perry's intellectual and ethical developmental levels,…

Discusses the "neo-Piagetian" concepts of Juan Pascual-Leone which are present in Piaget's theory. The concepts presented are the repertoire of schemes, mental processing capacity, and field dependence-independence. (Author/SA)

This master's thesis reports results of a study that: (1) developed, used, and validated a classification instrument of Piagetian developmental levels of high school science students (N=16); (2) determined the effects of traditional and Piagetian-based instruction of two formal topics, the mole concept and atomic theory, on students not classified…

Examines research in developmental psychology and science education that has attempted to assess the validity of Piaget's theory of formal thought and its relation to educational practice. Position papers (with little or no empirical support) are not included. (Author/JN)

Reports research supporting the hypothesis that concrete-operational college students playing the game Master Mind with an observer where there is verbal interaction designed to stimulate thinking about the problem-solving situation will show greater cognitive growth than subjects not playing the game. Implications for science instruction are…

Describes William Perry's scheme of intellectual development, focusing on the first five stages or positions collectively termed "ways of knowing." Suggests applications of this scheme for science teaching. (DS)

This book is intended to give teachers and student teachers a better understanding of the thinking of adolescent students in science lessons and to indicate the difficulties such students have in understanding the more abstract or formal ideas with which they are presented. It is practical in its orientation as the issues discussed are illustrated…

Data from 60 observations of 10 teachers and 10 each of their students showed that type/quality of teaching strategy predicted 37 percent of variance in engagement and that the more indirect the teaching strategy, the greater the students' involvement in learning tasks. Implications of these and other findings are discussed. (Author/JN)

Reports on a study designed to identify the hierarchical relationships among Piagetian cognitive modes and integrated science process skills for different Piagetian cognitive reasoning levels, and to determine whether positive vertical transfers could be validated. (TW)

Investigated implications of cognitive development of preservice teachers (N=91) as it related to their classroom teaching performance. Results obtained support a general portrait of teaching behavior specifically related to teachers of differing cognitive functional levels. Implications for professional training programs are discussed. (Author/JN)

Describes a series of laboratory experiments designed to provide concrete experiences with advanced inorganic chemistry lecture topics. Stresses student invention of chemical relationships and periodicity according to physical properties and reaction type. Includes comments on student performance and attitudes toward the experiments. (JM)

Though rooted in neo-Piagetian research, constructivism is an avenue of research that departed from the neo-Piagetian mainstream 20 years ago and has continued on a distinct path of development. For constructivists, learning is not knowledge written on, or transplanted to, a person's mind as if the mind were a blank slate waiting to be written on…

This study is concerned with preservice primary school teachers (N=100), a group of tertiary students who traditionally come from the secondary school stream. These students have, on the whole, avoided subjects like physics, chemistry, and mathematics that demand a high level of cognitive development for understanding/assimilation of abstract…

A cognitive gap between students' development and school curriculum may be one of the reasons why chemistry is difficult for high school students. This study examined cognitive development in the effect of modified instructional methods for students at the concrete stage of development. The Arlin Test of Formal Reasoning (ATFR) was used for…
