Practitioners and theorists do not articulate the purposes, theory, and practices of social studies adequately because they lack a basic understanding of the historical background. Examples of myths that hinder research and the development of social studies as a field are given as the field's history is traced. (SLD)

A macroscopic way of modeling hot air balloons using a Newtonian approach is presented. Misleading examples using a car tire and the concept of hot air rising are discussed. Pressure gradient changes in the atmosphere are used to explain how hot air balloons work. (KR)

The idea that errors and misconceptions in biology textbooks are often slow to be discovered and corrected is discussed. Selected errors, misconceptions, and topics of confusion about cell metabolism are described. Fermentation, respiration, Krebs cycle, pentose phosphate pathway, uniformity of catabolism, and metabolic pathways as models are…

Presents research findings related to students' intuitive ideas about the concepts of chance to inform teachers how students form their concepts of probability and statistics. Discusses adolescents' conceptions of uncertainty, judgmental heuristics in making estimates of event likelihood, the conjunction fallacy, the outcome approach, attempts to…

Describes the Bajema strategy for teaching meiosis and how it is used in the general genetics course at Ball State University and can be used to identify students who have misconceptions of meiosis that can interfere with their learning the basics of Mendelian inheritance. (Contains 11 references.) (MDH)

Explains that discussions should be used to help students think about their experiences with hands-on science learning. Making hands-on science "brains-on" will help challenge student's misconceptions. (PR)

Describes experiences with holding discussions on cloning at a variety of levels in undergraduate biology courses. Discusses teaching methods used and student reactions to the discussions. Contains 12 references. (WRM)

Summarizes how a group of teachers prepared a series of elementary-level inquiry experiences that focused on the study of land snails. Recommends and describes the K-W-L and Four Question inquiry strategies for younger and older students respectively. (WRM)

Contends that the large vocabulary used for precise purposes in physics contains many words that have related but potentially confusing meanings in everyday usage. Analyzes the treatment of Newton's Laws of Motion in several well-known introductory textbooks for evidence of inconsistent language use. Makes teaching suggestions. (Contains 11…

Examines conceptual change research to develop an instructional framework for science educators consonant with research on special education populations. Delineates a taxonomy of knowledge structures (classification, structure, process/mechanism, and concept/theory frames) derived from research that may be used to guide teaching strategy…

Learning by using the lecture method based on memorization, students miss the opportunity to learn basic concepts. Uses animation and diagrams to teach key concepts. (Contains 14 references.) (YDS)

Reports on the procedure and results of the trial of support materials that were developed for primary teacher mentors to help trainee teachers improve their medium-term and individual lesson plans. Concludes that trainees' practice in science improved in subsequent unmentored lessons, but good practice was not transferred to other subjects.…

Describes science-related questions asked by young students aged 4-6. Discusses appropriate responses to typical science questions. (WRM)

Challenges some commonly-held beliefs about what primary children can and cannot learn about astronomy. (Contains 16 references.) (Author/WRM)

This article investigates some of the antecedent conditions underlying the imputation of autonomy within conceptions of "teaching" and "learning". It links the history of those concepts with the separate roles and functions assigned to males and females in specific instances of educational practice. "Teaching" and "learning" are psychoanalysed as…
