Teachers' goals and orientations underlie their instructional decision making and can make the difference between "talking the talk" and "walking the walk" when trying to change lab instruction. Schoenfeld's "Resources, Orientations, and Goals" (ROG) framework was employed to shed light on the challenges involved in a…

Teaching quantum physics (QP) to high school (HS) students is gaining momentum, necessitating the exploration of various effective methods. Specifically, the research on quantitative teaching methods is still in its early stages. Understanding the power of Dirac notation (DN) in teaching is crucial for grasping the complexities of QP, as it…

Sound is one of the most commonly used physical phenomena that most of us use without considering its nature. Moreover, students often face difficulties in understanding acoustic phenomena, the most frequent one of which is the substance-based view of sound instead of a process of pressure and density differences. The current study introduces…

Troubleshooting activities require students to diagnose teacher-crafted erroneous examples by detecting and explaining the conceptual errors driving them. In a previous study, the author tested whether diagnosing erroneous examples and then scoring them using a rubric that contained the related worked examples, a step-by-step strategy to solve a…

The goal of this research is to provide a rich set of connections between two fields: (i) Nanoscale science and technology (NST) and (ii) topics from a common middle school physics curriculum. NST is emerging as one of the most promising new fields of the 21st century, which is one of the many arguments for including NST topics in secondary…

The instructional lab setting has been found to be dominated by prescribed tasks and pre-prepared lab kits. This was explained by teachers' need to guide students to simultaneously progress through a lab curriculum, which prompts them to standardize the lab experience. Nevertheless, prominent professional associations have persistently called to…

In high-school teaching of mechanics, we deal, among other things, with the nature of static and kinetic friction, forces that are proportional to the normal force. Under the influence of frictional forces, a body moves down a rough sloped decline at a fixed rate of acceleration that is independent of its mass. This situation does not apply to…

Pursuing both disciplinary authenticity and personal relevance in the teaching and learning of science in school generates tensions that should be acknowledged and resolved. This paper problematizes and explores the conceptualizations of these tensions by considering personal relevance, disciplinary authenticity, and common school science as three…

This study compared students' learning in troubleshooting and problem solving activities. The troubleshooting activities provided students with solutions to conceptual problems in the form of refutation texts; namely, solutions that portray common misconceptions, refute them, and then present the accepted scientific ideas. They required students…

Empirical studies have reported difficulties, confusion, and lack of understanding among students at all levels of instruction regarding the issue of weight--gravitation--weighing relationships. This study examined the impact of a new conceptual framework of weight, on a small group of 7th-grade students (N?=?14) in a middle school in Israel. This…

Threshold concepts are essential ideas about the natural world that present either a barrier or a gateway to a deep understanding of science. Weight, mass, and gravity are threshold concepts that underpin students' abilities to understand important ideas in all fields of science, embodied in the performance expectations in the Next Generation…

Creativity can be viewed from different perspectives, such as the creative thinking process, the product, the creative environment and the individual. The physics domain, which is based on experiments, research, hypotheses and thinking outside the box, can serve as an excellent grounding for creativity development. This article focuses on creative…

This paper describes the impact of the project-based learning (PBL) approach on learning and teaching physics from the perspective of pre-service elementary school teacher education students and an instructor. This approach promoted meaningful learning (mainly in the scope of projects), higher motivation, and active involvement of students in…

This study reports the effect of teachers' professional development in a two-year MEd program of High School Science Education, held from October 2010 until March 2012. Twelve out of the 33 teachers enrolled in the program participated in the study. The main research questions were: what are the teachers' perceptions of their own work and teaching…

The aim of the current research is to characterize the conceptual flow processes occurring in whole-class dialogic discussions with a high level of interanimation; in the present case, of a high-school class learning about image creation on plane mirrors. Using detailed chains of interaction and conceptual flow discourse maps--both developed for…
