Circus art excites amazes and delights. Most of circus genres are based on the principles of classical physics. Dialogic discussions are known as an instrument to identify conceptual barriers (misconceptions) and facilitate their further revision. The present study integrates the three worlds: physics education, dialogic teaching and circus art;…

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…

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…

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…

Several researches in physics education have demonstrated the problematic status of teaching the subject of gravitation and weight and students' knowledge of these concepts. This paper presents findings of a study of students' knowledge following instruction within a changed conceptual framework of the weight concept in several 9th grade classes…

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…

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…

Investigates whether elementary children can compare forces by comparing numbers of weights used in spring and balance problems. Reports that children did not identify weight and force, but they were able to use the ratio between the numbers of weights to compare forces. Suggests some instructional methods based on the findings. (YP)

Reports on research designed to discover whether certain conceptual difficulties experienced by present day students in the realm of action at a distance are parallel to the experiences of scientists in previous generations. Contains 60 references. (DDR)

Investigates gender issues in Israeli advanced placement physics classes. Analyzes matriculation exam scores from approximately 400 high schools over 12 years. Conducts semi-constructed interviews with 50 advanced placement physics students (25 girls and 25 boys). Discusses changes in the ratio of girls, performance, and factors that are…

The consistency, if any, with which force concepts are used by individual students in different, but closely related, contexts was investigated. A total of 534 university and high school students were tested to elicit their beliefs about the forces acting on various objects. Students' beliefs about the forces acting on objects at rest and in…

Investigates high school students' knowledge of natural phenomena related to the concept of light flux as it applies to the seasons and illumination after they studied optics. Discusses didactic, cognitive, and ontological perspectives in relation to specific changes in the science curriculum. Contains 71 references. (DDR)

A study (n=631) of children's ideas on motion of objects is reported. On three items of a four-part questionnaire, responses changed as the children matured, passing through distinct, successive stages with respect to their conceptual understanding. If teaching strategies to overcome misconceptions are to be effective, they must be appropriate to…

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)

Describes the MAOF physics education program which is designed to relate large parts of mechanics and electromagnetism to each other via the key concepts of field and potential, while at the same time treat students' conceptual difficulties. Finds that students who studied with the MAOF program significantly improved their physics knowledge…
