Observational methods are increasingly being used in classrooms to evaluate the quality of teaching. Operational procedures for observing teachers are somewhat arbitrary in existing measures and vary across different instruments. To study the effect of different observation procedures on score reliability and validity, we conducted an experimental…

This research aims at revealing (1) the suitability of physics e-scaffolding teaching media with mathematical and image/diagrammatic representation, as well as (2) the effectiveness of the e-scaffolding teaching media with mathematical and image/diagrammatic representation to improve students' problem solving ability and scientific attitude. It is…

The purpose of this study was to investigate the analytical thinking abilities and attitudes towards science learning of grade-11 students through science, technology, engineering, and mathematics (STEM) education integrated with a problem-based learning in the study of stoichiometry. The research tools consisted of a pre- and post-analytical…

In Life Sciences education internationally, including South Africa, the study of animal and organ morphology has traditionally involved dissections since the early nineteenth century. The major purpose of this study was to investigate how the engagement of learners with animal organ dissections may influence the development of problem-solving…

The high unemployment rate in South Africa compels potential entrepreneurs to start their own businesses in order to survive. Often this is with little or no formal training or education in entrepreneurship. Since problem recognition and problem-solving are amongst the most crucial competencies required for a successful entrepreneurial career,…

Sustained professional development can support STEM (Science, Technology, Engineering, and Mathematics) reform. The authors describe a 3-year study of sustained professional development for 3 diverse urban schools across the salient factors of fidelity of implementation of project-based learning, development of professional learning communities,…

Video recording is increasingly used in higher education settings to help students develop their oral presentation skills. However, little is known about the effect of video review for bringing about better high school student outcomes in oral presentation in formal (classroom) and informal (out-of-classroom) settings. Using a quasi-experimental…

This research investigated the similarities and differences between Korean and U.S. 9-12th grade science classrooms. The Reformed Teaching Observation Protocol was used to observe sixty-six classrooms (26 Korean and 40 U.S.) to examine the extent to which principles of constructivism framing both Korean and U.S. standards documents were observed.…

In a study investigating the effects of student engagement in inquiry learning through the development of Web sites, nearly every student reported having enjoyed the project, and the majority scored an A or B for their project grade. However, neither enjoyment nor high achievement on this performance task necessarily translated into high scores on…
