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…

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)

Explains the philosophy that forms the basis of a high school physical science course based on astronomy and the activity-based textbook that accompanies it. Cites specific examples of misconceptions related to astronomy and recommends various diagnostic and concept change strategies. (DDR)

Discusses the rationality of students' alternative frameworks by considering the role played by their beliefs, their understanding of other views, and the reasons for justification or rejection. Investigates the way in which 14-year-old boys see the effects of classroom learning experience on their ideas. (Author/YP)

Interviewed 10 students in a secondary school teacher education program to determine the students' understandings of environment. Four conceptualizations of environment were portrayed: social, political, bio-physical, and inclusive. Four conceptualizations of human-nature relationships were described: connected, separate,…

Examines preconceptions regarding several implicit vector characteristics that 15- to 17-year-old students possess just before taking their first physics course. Shows seven vector characteristics and three tasks for interviewing students. Presents the most common student preconceptions regarding each of the implicit vector characteristics. (YP)

Describes five astronomy education projects implemented by the Harvard-Smithsonian Center for Astrophysics Science Education Department and funded by the National Science Foundation. Project efforts have concentrated in three major areas: (1) curriculum development; (2) teacher support; and (3) classroom technology. (DDR)

Analyzed questionnaire responses of 152 prospective secondary mathematics teachers, 10 of whom were interviewed, to investigate their knowledge of the concept of function. Results indicated that many did not have a modern concept of function, a limitation that influenced their pedagogical approach. (Contains 45 references.) (MDH)

Ten preservice biology teachers were followed through the final year of their preservice education to assess the content and stability of their knowledge structures of biology. A questionnaire asking the subjects to list the topics which make up biology and to diagram these topics in relation to one another was completed three times during the…

This paper reports on a three-year case study of a secondary biology teacher that explores the use of two instruments: The Teachers Pedagogical Philosophy Interview (L. Richardson and P. Simmons, 1994) and the Secondary Science Teacher Analysis Matrix (J. Gallagher and J. Parker, 1995). The a priori research questions that guided this case study…

This study explored the possibility of developing classroom strategies that would encourage physics teachers to put greater focus on a more qualitative, metacognitive approach to problem solving. The empirical part of this research was carried out with students approximately 16 years of age in physics (i.e., introductory Newtorian mechanics)…

This paper addresses the evidence that secondary school students use to imply that they understand something in mathematics. As part of a larger study, an open-ended questionnaire probing several aspects of metacognitive self-knowledge, was administered to students (N=72) in four schools. Two previously identified types of understanding were…

This paper describes the actions of one secondary school mathematics teacher in establishing a community of mathematical practice within which students acquire not only knowledge and skills, but also the epistemological values of mathematics. Classroom observations over a period of 18 months, together with interview and questionnaire data, are…
