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…

Research indicates that troubleshooting activities that require students to reflect on pre-prepared erroneous examples, i.e. erroneous solutions to problems that correspond to common naïve ideas, impact their learning positively. These include asking students to diagnose erroneous examples; in other words, detect the conceptual errors and then…

This study addresses the development and evaluation of the Physics Problem-Solving Taxonomy (PPST), comprising five levels: retrieval, diagnosis, strategy, conceptual, and creative thinking. The taxonomy draws on Bloom's revised taxonomy in the cognitive domain, the Types of Knowledge Taxonomy, and the Problem-Solving Taxonomy in engineering. The…

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…

I examined the impact of a self-diagnosis activity on students' conceptual understanding and achievements in physics. This activity requires students to self-diagnose their solutions to problems that they have solved on their own--namely, to identify and explain their errors--and self-score them--that is, assign scores to their solutions--aided by…

Students at the junior high school (JHS) level often cannot use their knowledge of physics for explaining and predicting phenomena. We claim that this difficulty stems from the fact that explanations are multi-step reasoning tasks, and students often lack the qualitative problem-solving strategies needed to guide them. This article describes a new…

Israeli junior high-school science teachers usually have a background in biology, and their knowledge of physics is limited. We show that by improving teachers' "qualitative understanding" it is possible to increase their confidence and willingness to teach physics. We conducted three-day workshops for teachers (n = 92), which were…

Describes a study that illustrates that collaborative-thought experiments are emergent phenomena triggered by events as a whole rather than being predesigned. Points out that participants gradually adopt shared graphical representations and meanings. Contains 28 references. (DDR)

Students frequently misconceive the process of problem-solving, expecting the linear process required for solving an exercise, rather than the convoluted search process required to solve a genuine problem. In this paper we present an activity designed to foster in students realization and appreciation of the nature of the problem-solving process,…

Research in science and mathematics education has indicated that students often use inappropriate models for solving problems because they tend to mentally represent a problem according to surface features instead of referring to scientific concepts and features. The objective of the study reported in this paper was to determine whether 34 Israeli…

Addresses the problem of relating distance and scale by way of alternative models of perception taken from the history of science. Makes specific suggestions to broaden the scientifically-based actual activity zone of students. (Contains 19 references.) (DDR)

Discusses the results of a four-year study of the conceptions of energy held by science teachers in training. Concludes that the group held a number of different alternative conceptual frameworks. Contains 20 references. (DDR)

Explores the potential of the RAY learning environment in improving learning about optics. Results indicate that this environment, which includes a flexible ray-tracing simulation, had a significant effect on the spontaneous and correct use of the model by students in solving problems and a limited effect on conceptual understanding, but promoted…

Describes a hierarchical system of problem-solving strategies employed for the solution of a specific kind of problem about speed. Presents the results of 563 high school students tested with problems relating to distance, speed, and time. Provides a rationale for the methods used. (TW)

Information on the content of the intended science curriculum, what science was actually taught by the teachers, and how that science was taught is presented. Student achievement and attitudes were assessed using tests and questionnaires. Data were obtained from teachers regarding whether the content had been taught to the students (n=657) who…
