This study addresses high school students' conceptions of mathematical definitions of congruent and similar triangles. The findings indicate that many of the participants differentiated between definitions and theorems and did not always accept the congruent and similar triangles theorems as formal definitions of congruency and similarity. Based…

This article reports on findings from a phenomenological study of young people's perspectives on issues of sex, sexuality, and intimate relationships. The study utilised photovoice methodology to collect data from 15 young people aged 16-18 years. Analysis of 84 photovoice scenarios identified four narratives embodying participants' perspectives…

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;…

Circular motion is embedded in many circus tricks, and is also one of the most challenging topics for both students and teachers. Previous studies have identified several misconceptions about circular motion, and especially about the forces that act upon a rotating object. A commonly used demonstration of circular motion laws by physics teachers…

Young children are familiar with astronomical phenomena from everyday life, such as the movement of the celestial bodies or the shift from day to night. The present study examines the extent to which kindergarten students understand abstract concepts related to celestial bodies and processes (such as gravity and time), and whether they change…

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…

A sample of eighty Israeli in-service teachers filled out a questionnaire assessing their beliefs about the existence and the anthropogenic origin of climate change, their knowledge about the causes and consequences of climate change and the actions which can be taken to remediate it, as well as their level of concern about it and their readiness…

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…

In this phenomenological and qualitative study, we explored the experiences of six Palestinian-Arab Israeli Arabic teachers working at K-12 Jewish schools in Israel. We examine the three models of intergroup contact according to Brewer and Miller's theorisation -- category-based, differentiated, and personalised -- and their potential in…

Reduction is one of the key techniques used for problem-solving in computer science. In particular, in the theory of computation and complexity (TCC), mapping and polynomial reductions are used for analysis of decidability and computational complexity of problems, including the core concept of NP-completeness. Reduction is a highly abstract…

The goal of this study is to gain a better understanding of the experiences of Palestinian-Israeli minority teachers when teaching at majority state Hebrew secular schools in Israel. Specifically, the objective is to describe and analyze the role of the teachers' work-related experiences in shaping their sense of self-efficacy, job satisfaction,…

The present study describes the development and field testing of a simple apparatus-based diagnostic instrument (SABDI) that examines undergraduate students' understanding of the underlying physics principles that explain how simple acoustic apparatuses work. SABDI comprises 13 items. Based on previous research studies and the history of science,…

Dominant national myths create versions of reality that we need to deconstruct if we are to take students beyond stereotype. Using the USA as an example, histories that do not align with critical national narratives become silenced or muted. Preoccupation with Black and White dichotomies is just such a narrative that has hidden the significance of…

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…

What is Israel in the minds and hearts of young American Jewish children? Through interviews and photo and music elicitation exercises, this research uncovers how day school kindergarten students conceive of Israel. This study, part of an ongoing longitudinal project, shows how 5- and 6-year-old children are able to form a multilayered conception…
