There has been widespread concern about the provision of quality education (QE) for all learners in all contexts, but research evidence to inform this debate is quite divergent and in most of cases the question about achieving this desire seems to be full of myths. This paper examines a selection of embedded myths about QE in Tanzanian education…

Argues that much of the conceptual-change literature does not study change per se, but infers, often from interviews, changes in students' conceptions and discourse during learning. Concludes that what is needed are descriptions of learning trajectories. Contains 17 references. (DDR)

Combined free response questionnaire and interview procedure are used to probe students' ideas regarding how they believe they see both luminous and nonluminous objects and how they think they hear source of sound. From large sample of students studied (n=1901), prevalence of ideas in different age groups is compared, and progression can be seen.…

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,…

In most research that investigates factors influencing the success of analogies in instruction, an underlying assumption is that students have little or no knowledge of the target situation. It is interesting to ask what factors influence the success of analogies when students believe they understand the target situation. If this understanding is…

Discussion of students' prior knowledge and its effect on analogical reasoning focuses on four case studies of high school and college students that were designed to determine factors important for success in overcoming misconceptions via analogical reasoning. Explanatory models are explained, and abstract transfer versus explanatory model…

Interview data exemplify students' attempts to integrate the concepts of electrochemistry with related knowledge that they had previously constructed or acquired in other classes. The implications for minimizing potential misconceptions center on the difficulties students experience when using more than one model for explaining scientific…

Describes a pattern of failure to apply relevant scientific principles among pupils. Tenth grade Israeli students were tested and later interviewed in order to determine areas of knowledge in which there was some question concerning knowledge of scientific principles. Suggests that teachers must involve the pupils in situations in which erroneous…

Using a paper-and-pencil test consisting of multiple-choice situational questions which also require reasoning for the choices made, common misconceptions in light were identified. It was found that most of the students understand the basic properties of light at a knowledge level but had difficulty applying these concepts in novel situations.…

Describes a teaching model aimed at promoting conceptual change concerning heat and temperature. The model is used with teachers (n=2) and students (n=92) to explore its use as a professional development tool as well as a teaching strategy. Results indicate that the teaching model is effective in changing students' ideas and the approach resulted…

This paper analyzes the misconceptions high school students have about force and suggests that the misunderstanding of Newton's third law is the key to these misconceptions. Clinical interview and diagnostic test data (N=104) indicates that many students have a naive view of force as an acquired or innate property of single objects rather than…

The problem-solving difficulties of Nigerian preservice chemistry teachers (n=300) were investigated. The results from written tests and an interview show students were capable of constructing mental representations but not solution plans; had inappropriate approaches and strategies; exhibited structural errors relating to a disregard of given…

Discusses the frequent misconception displayed by students that chromosome structure is a function of chromosome number or ploidy. Provides detailed analyses of the evidence concerning the prevalence of this ploidy/structure misconception among students of introductory genetics and the potential sources for inaccurate communication that it can…

The consistency, if any, with which force concepts are used by individual students in different, but closely related, contexts was investigated. A total of 534 university and high school students were tested to elicit their beliefs about the forces acting on various objects. Students' beliefs about the forces acting on objects at rest and in…

Describes a diagnostic evaluation to measure the idea of the living cell as the basic unit of life. Describes the classification of student knowledge as common knowledge, wide-spread lack of knowledge, inadequate alternatives, and contradictions. (YP)
