Evidence of certain aspects of teaching can be best assessed with a well-designed observation instrument. This instrument was designed to assess the enactment of the essential elements of…

This article explores the beliefs and practices of a high school biology teacher through three interrelated theoretical frameworks: common knowledge, collaborative learning, and communities of practice. The data were obtained from an in-depth case study of Maria, a biology teacher from a Mexican public high school that was participating in a…

In a study to evaluate an approach for improving the critical thinking skills of middle school science students, 60 students were given the assignment of completing three guided laboratory activities and writing a report for each. In writing their reports, students were expected to identify the manipulated variable, identify the responding…

In New Zealand and internationally claims are being made about the potential for information and communication technologies (ICTs) to transform teaching and learning.

The BioBridge Professional Development model was created to bring current and relevant science into the high school classroom. The purpose of this intervention was to connect teachers with relevant science and to create innovative, hands-on activities that engage students, with the goal of increasing student interest in STEM careers. To this end,…

In science education, inquiry-based approaches to teaching and learning provide a framework for students to building critical-thinking and problem-solving skills. Teacher professional development has been an ongoing focus for promoting such educational reforms. However, despite a strong consensus regarding best practices for professional…

Presented are the results of an exploratory study in which methods used in research on teaching were adapted to research on elementary school science teaching. An observation system was designed that enabled an observer to record detailed, context-specific information about the behavior of teachers (N=22) and students in grades 2-5 during…
