This mixed-methods study probed the effectiveness of three kinds of objects (video, theory, metaphor) as common reference points for conversations between online learners (student teachers). Individuals' degree of detail-focus was examined as a potentially interacting covariate and the outcome measure was learners' level of tacit knowledge related…

Tourette syndrome (TS) is a neurobiological disorder marked by a wide range of involuntary motor and vocal movements and sounds called "tics" (American Psychiatric Association, APA, 2000). This syndrome is frequently misunderstood and difficult to diagnose (Chamberlain, 2003). Recent television shows featuring the topic of TS such as "The Oprah…

In her second semester teaching for Arizona State University, the author suddenly found herself teaching a fully online writing course for the first time. Originally she had been scheduled to teach the course in a hybrid format, meeting face to face with students once a week; however, a coding error in the online class schedule resulted in the…

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…

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)

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…

Argues that doing and learning science are not the same thing. Suggests strategies involving active learning of a nonpractical nature which encourage discussion of science by children working in small groups. Presents examples of less familiar practical alternatives. (JRH)

Explains how misconceptions act as barriers to learning and must be addressed by teachers in the delivery of instruction. Points out that if misconceptions are not overcome, no new learning will result from a student's time in the classroom. Reports the results of an action research project that concluded that the majority of students make no…

Children's ideas about radiation and radioactivity are reviewed and several common areas of misunderstanding are identified. An approach to teaching the topic at the secondary school level which seeks to specifically address known difficulties is outlined. (CW)

Concepts used by two classes of grade eight students, one advanced and the other average, to explain the changes that occur when water is heated to boiling are presented. Little difference was found between groups in terms of the personal misconceptions used to explain boiling. The changes that take place in conceptual knowledge immediately after…

Fifteen true-false statements are provided that are to be used to spur discussion and arguments about the concept of motion. Each statement is carefully worded to sound plausible, but each one attacks some misunderstanding common to students who are encountering Newton's mechanics for the first time. (KR)

Teachers at all levels are encouraged to use role-playing and simulation. Unfortunately, teachers usually overestimate role-playing's learning value and often ascribe too much power to simple simulation activities. Teachers use these methods mainly to change behavior (and values), not reinforce curriculum content. Sociodramas (scenes based on…

Although teachers at all levels are encouraged to use role-playing and simulation, they usually overestimate role-playing's learning value. Teachers use these methods mainly to change behavior (and values), not reinforce curriculum content. Sociodramas (scenes based on typical situations facing children) are more effective role-playing activities…

Children of 2 different age groups (11-12, n=246; and 13-14, n=196) were asked to draw and write about dissolving in 2 different ways. Greater percentage of children at both ages gave accurate particle interpretation that accurate view of observable process. Consistency between two ways of looking at dissolving was not found to improve with age.…

This study questions the effectiveness of a traditional teaching-by-example technique when used with students who hold misconceptions. Interview techniques were used to explore students' (n=21) responses to two different uses of examples and to provide indications of student reasoning. Results indicate that when students hold a misconception,…
