Helping students better understand how scientists reason and argue to draw scientific conclusions has long been viewed as a critical component of scientific literacy, thus remains a central goal of science instruction. However, differences of opinion persist regarding the nature of scientific reasoning, argumentation, and discovery. Accordingly,…

Investigates the role of complex instructional analogies on concept acquisition in an introductory college genetics course. An experimental treatment included complex instructional analogies. A control group received expository instruction alone. Finds significant differences in student achievement in favor of the experimental group. (Author/MM)

Reports a procedure for training fifth and seventh grade students to substantially improve their understanding and use of controlled experimentation procedures. (SL)

Presents a descriptive analogy comparing Piaget's theory of intellectual development to the development of athletic abilities in order to provide insight into Piagetian theory. (SL)

The general purposes of this study were to analyze responses on five Piagetian formal operational tasks in a test-retest situation to determine the extent to which taking a pretest effected scores on posttests and to determine task and examiner reliabilities. Significant test score gains on Piagetian tasks appeared to result from test-retest…

Investigated the degree of relationship among the performance of 28 seventh grade students on the following three formal operations tasks: chemical combinations, bending rods, and balance beam. Results show that task performance ranged widely from early concrete operational to fully operational. (HM)

Investigated the relationship between syntactical complexity of high school students' written language and their ability to reason formally. Format reasoning ability of 50 high school students was measured by a 15-item group-administered demonstration test developed by Lawson. (HM)

The relationships between 54 sixth grade students' performance on the Piagetian balance beam and bending rods tasks were correlated with their answers to value-laden questions. Significant positive relationships were observed. Implications from these findings for science instruction are discussed. (CP)

Three Piagetian tests of formal reasoning were administered to 65 high school biology students after half of this group had been exposed to a training session involving the control of variables. Among the results of this study was that the concrete operational students benefited more from the training session than did the formal operational…

Two Piagetian tests which require manipulation, two conservation tasks, and the Longeot pencil and paper formal reasoning test were administered to 62 high school biology students. For all measures the males' mean level was higher than that of the females. (MLH)

Describes an investigation of 35 secondary school students to examine the relationship among scores on 10 Piagetian tasks used to assess levels of concrete and formal reasoning and problem solving abilities and scores on a standardized reading examination used to measure reading ability. (Author/GS)

Investigated and confirmed is a correlation between grades awarded on the basis of students' ability to respond with higher-order cognitive processes in college biology classes and performance on Piagetian-type tasks, in which cognitive style dimension of field dependence-independence was assessed for each student. (CS)

Contains the fourteenth installment in the series of annual Summaries of Research in Science Education. The review is organized around specific disciplines at specific grade levels. Topics without specific disciplines or age levels and those that cut across these categories have been given separate headings. (ML)

Many science curriculum development projects have the goal of increasing students' ability to employ scientific or formal reasoning strategies. Argues that longitudinal data of students who acquired formal reasoning strategies as a consequence of specific instruction are needed to provide evidence that these skills will help in other academic…
