This study employed hierarchical linear models (HLM) to investigate Peer-Led Guided Inquiry (PLGI), a teaching practice combining cooperative learning and inquiry and tailored for a large class. Ultimately, the study provided an example of the effective introduction of a reform pedagogical approach in a large class setting. In the narrative, the…

A neuromathematical model of information processing applied to science learning is expanded to include two coefficients representing the motivational state of the learner. The inclusion of these coefficients (which are described) permits modeling of the effects of variations in motivation on the rate and amount of information in learning tasks.…

Outlines a narrative method for the study of classrooms. The main feature of the method is the reconstruction of classroom meaning in terms of narrative unities in the lives of classroom participants. The work's theoretical character is introduced by comparison and contrast with Schon's "The Reflective Practitioner: How Professionals Think in…

This exploratory study determined whether a mathematical model of mastery learning provided a good fit for achievement data obtained from student progress in an introductory, college-level astronomy course for nonmajors. Results provide positive but not compelling evidence that the model of mastery learning is correct. (JN)

Tested Richard Duschl's triadic model of the growth of scientific knowledge against research practices of 10 accomplished life scientists. Reports that the scientists were willing to change their aims, methods, or theories and were both realists and relativists depending on the scientific discourse about the phenomena in question. Discusses…

Applies Kuhn's model of the structure of scientific revolutions, Popper's hypothetic-deductive model of science, and Lakatos' methodology of competing research programs to a historical biological episode. Suggests using Kuhn's model (emphasizing the nonrational basis of science) and Popper's model (emphasizing the rational basis of science) in…

This study is a synthesis of practice and research related to use of behavior analysis to train teachers. An idealized model for training science teachers is presented with research related to the model categories reviewed and analyzed. Results (based on meta-analysis) which support the idealized model are presented and discussed. (Author/JN)

Monitoring student performance on microcomputer drill and practice programs over time provides evidence that students learn from the programs at different rates and that programs differ in the rates at which they impart learning to students. Implications of these and other findings for science teaching are addressed. (JN)

An empirical analysis of the relationship between science reasoning skills and the amount of information acquired during science learning as predicted by a neuromathematical model of information processing is presented. Subjects were 93 adolescents (mean age of 15.4 years old) with a IQ range of 91-142. (Author/JN)

Determined the effects of reasoning, use of models during testing, and sex type on posttest achievement in chemical bonding under controlled instruction. Indicates that chemistry students' (N=84) reasoning capabilities influenced performance; other variables were not significant. Other conclusions are noted and discussed. (DH)

Investigated factors which influenced teachers' (N=5) behaviors during the implementation of an audio-tutorial freshman college biology course in a high school setting and developed a structural model showing the interrelationships of these factors. (JN)

Examined is the question of how science attitude scores can be expected to predict science-related behaviors. Discussed is a historical perspective of this problem and five attitude-behavior perspectives. A summary for science educators is provided. A list of 77 references is included. (CW)

A model for a desired state master's degree in science education was generated by identifying the training needs of teachers presently teaching science in southern Florida. The model includes an analysis of the current master's program, recommended changes, and rationale for these changes. Implications for noncredit inservice activities are noted.…

Investigated was the effectiveness of interventions designed to mediate the negative influence of ascription on the scientific talent pool. Findings related to the effectiveness of tutoring, career counseling, exposure to research and to role models, and after school programs reinforce the importance of prerequisites for increasing minority…

Discusses the science education research agenda from the viewpoints of learning theorists, political and social scientists, counseling psychologists, cognition psychologists, and pedagogical researchers. Indicates that a broader perspective of these areas helps to link the research agenda to science teachers' questions/concerns, and to such areas…
