ABSTRACT
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; and provides a research foundation for experiential physics teaching through dialogic discussions about circus tricks (DDCT) in formal and informal setups. It aims at examining the potential of DDCT as a tool for identifying misconceptions and facilitating conceptual change regarding physics concepts. The study encircles about 40 DDCT provided in the Israeli KESHET circus. In total, about 5,500 people watched the shows. From them, about 400 actively participated in the DDCT. We analyze in details four typical DDCT relating (a) circular motion, (b) moment of inertia, (c) torque, and (d) heat transfer. For each DDCT we demonstrate the way it pinpoints participants’ knowledge and its implementation in circus devices’ analysis. Further we examine whether and how the DDCT could facilitate developing physics knowledge and/or going through a meaningful conceptual change regarding each of these concepts. Due to our results DDCT seems to be an original and promising approach to bring advanced physics ideas to the general public, in ways that are interesting, experiential and relatively easy to understand. We finish with practical recommendations for physics educators (as well as circus artists) who would like to implement DDCT in their classes (shows).

ABSTRACT
Augmented reality is defined as a technology in which real world and virtual objects are combined with a simultaneous interaction. The aim of this study is to determine the effect of augmented reality use on students' achievement, misconception and course engagement. A (matched) quasi-experimental research design with both pretest and posttest control groups was used in the study. The sample of the study consisted of 118 seventh grade students receiving education in six different classes. The students in the experimental group took their lessons with an augmented reality learning material, while the students in the control group continued using their traditional course materials. An achievement test, a misconception test and the student course engagement questionnaire were used as data collection tools. As a result of a 7-week implementation, this study found that augmented reality technology increased the achievement level of students and eliminated their misconceptions. However, the study also found that augmented reality technology did not affect the course engagement of students.
