There are two basic guiding referents in the present investigation: the teaching and learning of school-level geometry (basic concepts of Euclidian geometry and measure) and the analysis of the conceptions of prospective primary teachers in Spain. The work assumes that such conceptions appear and develop during school years, and that consequently,…

This study examined some long-term impacts of a professional development program, Teachers in the Woods. Several outcomes of the program were acknowledged by participants as having been valuable: a network of like-minded teachers, a network of scientists and teachers, and an increase in teachers' ecological knowledge and field skills. The authors…

In this study, we hypothesize that cases demonstrating exemplary practice in the science classroom can be used as a source for learning content and pedagogical skills that will improve teachers' self-efficacy beliefs. Twelve preservice elementary science teachers are followed as they participate in a case and case method activity illustrating the…

This study investigated changes in Korean science teachers' perceptions of creativity and science teaching after participating in an overseas professional development program. Participants were 35 secondary science teachers. Data were collected from open-ended questionnaires and interviews. Results indicated that participants showed a growing…

The nature of science (NOS) has a prominent role among the national science education content standards at all grade levels, K-12. Results from a national survey of collegiate science educators indicate the perception that the greatest contributors to preservice teachers' understanding of the nature of science were science methods courses,…

The purpose of this study was to describe selected content knowledge held by 52 preservice elementary teachers about the observable phases of the moon and the monthly pattern of change in observable phases. Data were obtained from participants in a physics course before and after they received inquiry-based instruction designed to promote…

This study explored the influence of university-based teacher education courses on preservice teachers as they engaged in the field-based portion of their preparation. Forty-two preservice teachers contributed reflective writings about the successes and challenges they faced during field experiences in light of knowledge and skills learned during…

To what extent can a large-scale national teacher-enhancement project help science teachers employ new pedagogical methods in the science classroom? In this study, data from 13 high school physics teachers who taught 23 classes with 401 students were examined to determine the extent to which a teacher-enhancement project can alter teachers'…

The purpose of this study was to develop, validate, and establish the reliability of an instrument that measures preservice teachers' self-efficacy in regard to the teaching of science as inquiry. The instrument, Teaching Science as Inquiry (TSI), is based upon the work of Bandura (1977, 1981, 1982, 1986, 1989, 1995, 1997), Riggs (1988), and…

The purpose of this study was to examine changes in personal science teaching self-efficacy (PSTE), outcome expectancy (STOE), and science conceptual understanding and relationships among these in preservice teachers. Seventy preservice teachers enrolled in science teaching methods courses participated in this study. PSTE, STOE, and science…

SMAR[squared]T: Science and Mathematics Academy for the Recruitment and Retention of Teachers is an NSF-funded project for the alternative certification of science and mathematics teachers. Since 2003, we have recruited 4 cohorts of students for 2 different routes to postbaccalaureate teacher certification for teaching grades 5-12. Because we did…

This paper examines the summer component of a year-long professional development program. The program was developed based on recent models of effective professional development that indicate that teachers should guide the direction and focus of the professional development program. Specific activities in the summer program were adapted from a…

In many teacher preparation programs, student teaching serves as a culminating event that bridges academic coursework and the realities of classroom teaching. Therefore, it represents a significant aspect of preservice teacher education. This study explored student teaching as it was experienced by 13 middle and secondary science preservice…

The purpose of this study was to examine how the practicing science and mathematics teachers participating in the University of Florida's Teacher Research Update Experience (TRUE) perceived their experiences in Summer 2000. We conducted in-depth interviews and collected data from survey questionnaires and addressed research in the following areas:…

This paper describes how interpretations of inquiry have changed during the 20th Century. These multiple meanings have resulted in (a) confusion among K-12 teachers of science and (b) various interpretations by science teacher educators. Suggestions are provided for preservice programs (both science and methods courses), professional development…
