Recent research has shown that serious misconceptions frequently survive high school and university instruction in mechanics. It is interesting to inquire whether Newton himself encountered conceptual difficulties before he wrote the "Principia." This paper compares Newton's pre-"Principia" beliefs, based upon his writings,…

Advanced knowledge acquisition in a subject area is different in many important ways from introductory learning (and from expertise). In this paper some of the special characteristics of advanced learning of complex conceptual material are discussed. The paper notes that these characteristics are often at odds with the goals and tactics of…

Describes the distinctive features of the common snapping turtle. Discusses facts and misconceptions held about the turtle. Provides guidelines for proper care and treatment of a young snapper in a classroom environment. (ML)

Uniform illumination levels in the classroom and focused brightness on the "teaching wall" made good sense for students in Henry Ford's era. If you were training to take your place on the assembly line, you needed to focus on the work at hand and ahead to your supervisor, but the future no longer belongs to students who look only straight ahead.…

The paper identifies possible factors associated with changes in style and presentation of diagrams of lunar phases and eclipses in school textbooks and other resources. Science curriculum resource materials used extensively during the past two hundred and fifty years in North America and Australia provide insights into teaching and learning of…

Discrepant questioning is a teaching technique that can help students "unlearn" misconceptions and process science ideas for deep understanding. Discrepant questioning is a technique in which teachers question students in a way that requires them to examine their ideas or models, without giving information prematurely to the student or passing…

During the last decades, an increasing awareness has developed that humankind will have to make important decisions about the environment which will demand substantive knowledge of critical ecological phenomena such as the production and decomposition of biomass (World Commission on Environment and Development, 1987). As a biology teacher the…

Many would-be reformers have become so entranced with educational standards that they fail to recognize accompanying problems, such as optimal generality and subordination levels. There is really no difference between instructional objectives and content standards. Other perils of content standards include inadequate descriptive vigor,…

For most students textbooks are the main source of their information about scientific concepts; however, there are a number of errors which frequently appear in textbooks and are consequently transmitted to both teachers and students. Some of these errors which may represent widespread misconceptions of teachers are outlined. (Author)

Explores how teachers conceptualize self-esteem and related curricular practices, using survey data from 68 midwestern urban teachers. Relying on assumptions and intuitions, teachers believed that low self-esteem is endemic to most urban children, reinforced by kids' urban context, and tantamount to being at risk behaviorally and academically.…

Data from First in the World Consortium (group of 20 suburban school districts that paid to have students take the Third International Mathematics and Science Study tests) and TIMSS dispel pervasive myth that only 1% of American students score as well in math as average Japanese student. Before copying Asia, American educators should examine…

Educators wishing to help low-achieving children must discard the concept of learning disabilities entirely and adopt a new way of thinking about children's learning problems. Learning-disabilities specialists should become learning specialists who understand the cognitive processes typically involved in acquiring academic skills, ways the…

Success of programs aimed at teaching racial tolerance depends on ability to confront three misconceptions about racism: life is good for racial minorities; racism is declining; and America can be a color-blind society. These myths have been absorbed into beliefs and attitudes of well-educated, open-minded people. Today's Gallup Polls actually…

Getting schools to leap onto the Information Highway is the latest in a series of corporate forays marked by ignorance, self-interest, and marketing madness. Educational implementation of computer-based technology is highly experimental, despite the billions spent annually. The competitive jockeying for position to build and fill the…

Investigated DIALOG's RANK command to generate a list of prominent authors in biodiversity for use in cocitation studies. Concluded that RANK did not retrieve a quality set because highly cited authors of general texts presented a misaligned picture of specialization. Suggests that limiting citations to journal articles would present a more…
