Presents data which leads to the construction of a response to the question of how different phases of the learning cycle influence physics students' content achievement and attitudes. Discusses the importance of the learning cycle in science instruction and the strength of using contrasting techniques (qualitative and quantitative) in research.…

Discussed is the issue of the appropriateness of applied science approaches to evaluation in environmental education. The relationships between characteristics of applied science approaches to evaluation and the special characteristics of environmental education are explored. (Author/YP)

Explores the nature of explanations used by 20 middle school science teachers utilizing the constant comparative analysis method in analyzing transcripts of classroom discourse. Discusses a subsuming categorical framework for the 10 types of explanations generated, along with examples of each type, namely: analogical, anthropomorphic, functional,…

Reports on 18 months of action research that examined the effectiveness of using the history of science to promote British students' understanding of the nature of science. Both quantitative and interview data offer substantial evidence of a strategic movement away from serendipitous empiricism and toward an appreciation of the interactive nature…

Summarizes the results of a preferred method of study questionnaire in which college students explained how they approached reading a new textbook. Reports that women showed a significant preference for adopting a single method of study. Indicates that there was no discernable relationship between study strategies and college level. (CW)

Investigated were children's reactions when allowed to choose their own apparatus and perform experiments with appropriate directions available. Few students invented their own experiments; most followed the available printed instructions. (SL)

Reports on a study in which clinical interviews were conducted with three elementary school children to determine the extent to which they held naive misconceptions about important biological topics, and to determine agewise trends in the development of biological knowledge. (TW)

Reports the results of two experiments that examined the relative effects of questions requiring decisions, statements providing the decision information to the students, questions not requiring decisions, and control procedures on student's memory for chemistry text reading materials. Discusses results in terms of an elaboration perspective on…

Interview data exemplify students' attempts to integrate the concepts of electrochemistry with related knowledge that they had previously constructed or acquired in other classes. The implications for minimizing potential misconceptions center on the difficulties students experience when using more than one model for explaining scientific…

Discusses children's ideas about colored objects and colored shadows, with special attention to the organization of these ideas into mental models. The clarification of these models provides instructional tools that serve to assess and confront students' naive conceptions. Subjects were visitors to a science museum who engaged in interactive…

Described is a study that confirms positive effects on student achievement of manipulation of molecular models by high school chemistry students over a long period of time. Also examined but unanswered were questions regarding applications of Piaget's theories in determining differential effects for concrete and formal operational students. (CS)

Investigates whether enriching text with analogies, similes, and metaphors has an impact on student cognitive learning and attitudes. Reports no gain on achievement, negative gain on attitude, no gain on proposition recall test, and negative gain on student attention to the text. (YP)

Studies the effect of intellectual development, degree of field independence, mental capacity, amount of prior genetics knowledge and amount of fluid intelligence on reading comprehension and/or genetics achievement of students enrolled in a nonmajor biology course. Concludes that developmental level was the most consistent predictor of…

Explains science teachers' perceptions and decisions about the development and implementation of a science/technology/society curriculum. Discusses the teacher interviews based on teachers' decisions. Summarizes five themes: concerns over content, discomfort with grouping, uncertainties about evaluation, frustrations about student population, and…

Quantitative outcomes from the Attitudes toward Science Inventory, as well as interview results, indicate that nonscience college majors have high anxiety levels in combination with low levels of motivation when confronted with science material. Further, these attitudes toward science change with exposure to introductory, science instruction with…
