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…

Describes an experiment that uses a bottle, a cork, and a wooden match to study students' explanations of what they observe to reveal misunderstandings about pressure and to produce some incorrect interpretations such as creation of a gradient of pressure. (DDR)

A Minneapolis superintendent presents diary excerpts of his three-year experience and dispels myths about improving education. He argues the futility of believing that more, less, or private is better; that educators are nincompoops; or that money talks. Transforming education requires core goals, customer support, consequences (accountability),…

Develops a "theory of stretched analogies" to explain limitations of student-as-customer and athletic motivational notions. Schools are neither shopping malls nor knowledge factories; for unengaged students, there will be nothing to purchase. Also, caring teacher-coaches must decide how high to set the bar. The goal is helping all…

Explains how students' alternative conceptions about curriculum topics interfere with classroom learning. Describes the Royal Society of Chemistry's Teacher Fellowship Project entitled "Challenging Misconceptions in the Classroom," which develops classroom materials to diagnose and challenge specific alternative conceptions. Uses key…

Presents an account of one teacher's path to realizing the depth of intuitive beliefs about science. Organizes chemistry misconceptions into eight patterns of reasoning that include thinking rules and alternative conceptions. (DDR)
