Describes children's conceptions of the structure and function of the human digestive system based on an investigation carried out with children aged 4-10 (n=45). Finds that children possess biological knowledge as an independent knowledge domain from the age of four. Discusses acquisition of and barriers to scientific concepts related to human…

Some serious difficulties that students have in understanding physical optics may be due in part to a lack of understanding of light as an electromagnetic wave. Describes the development and use of tutorials designed to address students' conceptual difficulties. (Contains over 15 references.) (Author/WRM)

Critiques the scientific merit of a claim against evolution that is based on a calculation of the level of salt in the oceans. (WRM)

Suggests a few alternative approaches to teaching algebra that allow students to construct and reflect upon meanings for expressions and equations. The three lessons, which require extended discussion and reflection, are "Representing Algebraic Expressions,""Evaluating Algebraic Statements," and "Generating Equations." (WRM)

Educators who benchmark other "successful" educational agencies and/or private-sector organizations to find "best-practice" ideas face potential pitfalls. The benchmarked organization may have incompatible goals and objectives, obsolete processes and operations, and different primary clients and beneficiaries. Most organizations, public or…

New results in neuroscience point to the brain's lifelong capacity to reshape itself in response to experience. Educators' great challenge is developing learning environments and practices to exploit the brain's lifelong plasticity. This challenge will be met by carefully studying human behavior and behavior change. Brain science should return to…

Argues that, for a misconception to be abandoned, the learner must come to see it as unsatisfactory. The new conception must be intelligible, plausible, and fruitful. Suggests that students should have an active cognitive involvement in the process. Contains 16 references. (DDR)

Pre/posttest data from six elementary teachers who received inservice training in science showed that the training enabled them to acquire a scientific view of the concept of energy efficiency. Before training, they tended to confuse it with energy conservation. (SK)

Argues that some common student misconceptions are perpetuated by teachers, textbooks, and rote-learning methods and that strategies to challenge and change these misconceptions are needed. Focuses on misconceptions related to the eye and how it works. (DDR)

A commonly held notion of how earlier generations of immigrants were educated--often used as the chief argument supporting English immersion--is a myth. Far from succeeding by immersing themselves in English, immigrant groups did much worse than the native-born; some groups, particularly Italians, did much worse than others. Research findings are…

Reconstructs students' and teachers' understanding of the structure of the atom based on a framework characterized by considering the history of science as competing research programs and by believing that some great scientific research programs progress on inconsistent foundations. Contains 107 references. (DDR)

Discusses the long running debate on teaching evolution in public schools. Recommends using the 5E teaching cycle of engage, explore, explain, elaborate, and evaluate to show that scientific concepts and theories can be fundamental. (Contains 20 references.) (YDS)

Analyzes three widely-held conceptions of critical thinking: as one or more skills, as mental processes, and as sets of procedures. Considers each a misconception and offers alternative proposals for teaching critical thinking. (CMK)

Teacher involvement in decisions may detract from teaching. This article presents three case studies (concerning a teacher-owned program, teacher involvement in selecting a new principal, and an autocratic principal's failed experiment with participation) that examine pitfalls. Sunset clauses, a good centralization/empowerment balance, and an…

Delineates the myths, mysteries, and distortions surrounding rites of passage for African American youth and investigates the educational implications of these rites. The initiation process is examined, and the importance of carefully resurrecting these rites of passage to the socialization of African American youth is discussed. (GR)
