Reviews a study which sought to assess the influence of field activities, as compared to classroom-contained activities, upon students in an earth science laboratory course. Test results indicated that both groups had identical levels of lower-order learning but the field-oriented group demonstrated higher levels of understanding and application.…

Investigates the effect that manipulation of the extent of formal reasoning required for solving chemistry problems has upon student performance, and presents a cognitive model for the qualitative analysis of that effect. Concludes that the developmental level of students is the most important predictor of problem-solving success given significant…

Reports two small-scale studies that investigate whether the understanding of scientific concepts will be enhanced by using collaborative pairings. Examines how types of pairings affects performance. Finds students working in pairs outperformed their counterparts working individually. Also notes that dyads improved upon initial performance in…

Some science educators who are interested in conceptual development have considered the phenomenon of student misconceptions and alternative frameworks. Researchers have used a variety of terms to describe the situation in which students' ideas differ from those of a scientist about a particular concept. This digest was produced to briefly…

While logical reasoning skills are related to success in science, the relationship between thought and formal logic is not clear. Propositional Logic Test (PLT), error patterns of students' interpretations of logical proposition, and developmental patterns of the error type are described. Examined is the relationship between logical reasoning…

Reports on misconceptions held by intermediate grade students concerning chemistry textbook concepts, on the relation of reasoning ability to those misconceptions, and on the extent that textbooks encourage misconceptions. Concludes that the level of understanding displayed for the selected concepts, in combination with the nature of students'…

Conceptual change teaching is an instructional method that helps students modify, extend, or exchange their alternative conceptions for the appropriate scientific conceptions. Provides activities and a diagnostic test to apply the method to the concepts of heat and temperature. (MDH)

This book on classification abilities is part of a series designed to assist beginning and experienced teachers in becoming regular evaluators of their own instruction. The book consists of two sections. The first section provides information on: resemblance and consistent/exhaustive sorting; multiple membership and inclusive classifying; and…

This book on conservation abilities is part of a series designed to assist beginning and experienced teachers in becoming regular evaluators of their own instruction. The book consists of two parts. The first part provides information on: conservation related to number, length, solid amount, liquid amount, discontinuous length, area, weight, solid…

This book on propositional reasoning is part of a series designed to assist beginning and experienced teachers in becoming regular evaluators of their own instruction. The book consists of two parts. The first part provides information on probabilistic, disjunctive, combinatorial, implicational, deductive, and proportional reasoning and on…

Reports results of the Second International Science Study concerning achievement in physics of U.S. high school students. Makes comparisons between students of 13 other countries and U.S. students, between first- and second-year U.S. physics students, and between U.S. students tested in the mid-1980s and those tested in 1970. (MDH)

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…

Reports on a study that examined the differential effectiveness of traditional and discovery methods of chemistry instruction in Zambia. Compared were the teaching of science concepts, understandings about science, and scientific attitudes to learners at the concrete and formal levels of cognitive development. (TW)

More than 1,600 middle school students, including an experimental group exposed to the Biological Science Curriculum Study (BSCS), were administered the Modified Nature of Scientific Knowledge Scale. Results indicate that the students utilizing the traditional science curriculum possessed a significantly better understanding of the testable nature…

This digest addresses cognitive learning with respect to outside-the-classroom instruction at the elementary school level. It notes that affective, not cognitive, learning has traditionally been the primary objective of field instruction at all K-12 levels. Therefore, most educational research in field instruction has been mainly non-cognitive in…
