Many proofs of the arithmetic mean harmonic mean inequality have been proposed based on the rich connections between mathematics and physics. Sometimes the Arithmetic Mean Harmonic Mean inequality is proved by using electric networks. In this note, we use a simple set of two springs, instead of four springs which would be the equivalent set to…

International research shows that primary school teachers don't have the necessary level of self-efficacy to provide high quality science learning and teaching opportunities to their students. The aim of the present study is to validate the Science Teaching Efficacy Belief Instrument (STEBI-B) and to investigate the self-efficacy beliefs of 408…

The purpose of this study is to develop an up-to-date scale with high validity and reliability that could reveal the attitudes of high school students towards the physics course. In the process of developing the scale in question, three independent samples were formed, and the data obtained from a total of 1118 high school students were analyzed.…

: Current research on self-efficacy beliefs of interdisciplinary science teaching indicates shortcomings in facing recent teaching challenges in secondary education and corresponding valid instruments. Thus, we designed the Self-Efficacy Beliefs of Interdisciplinary Science Teaching (SElf-ST) instrument based on a pedagogical content knowledge…

Motivation and interest affect students' learning especially in Physics, a subject learners perceive as abstract. The present study was guided by three objectives: (a) to adapt and validate the Science Motivation Questionnaire (SMQ-II) for the Ugandan context; (b) to examine whether there are significant differences in motivation for learning…

This research aimed to explore the correlation between Indonesian University students' conception of learning physics and their physics' self-efficacy. A total of 279 students who were majoring in physics education participated in this research and were invited to complete two instruments: the conception of learning physics (CLP) and the physics…

The performance of teachers is an important factor that must be considered in efforts to improve the quality of education. Teacher's performance is affected by many factors. Factors that affect the performance of teachers are principals' managerial leadership and compensation. The purpose of this study was to determine the effect of principals'…

This research study was conducted to address pre-service physics teachers' assessment literacy and its implementation into practice. The research was both quantitative and qualitative in nature. For the quantitative aspect of the study, the researchers determined the participants' assessment literacy after their enrolment with the…

In this paper, we acquire and analyse high-speed videos of a spring-mass system oscillating in glycerin at different temperatures. Three cases of damped harmonic oscillation are investigated and analysed by using high-speed video at a rate of 120 frames s[superscript -1] and Tracker Video Analysis (Tracker) software. We present empirical data for…

The aim of this study was to create an instrument to measure elementary teachers' interest in teaching chemistry. The interest in chemistry teaching instrument (ICTI) was created to measure both the affective and cognitive components of interest. After establishing the face and content validity of the instrument, the internal consistency of the…

Every sphere of life has been revolutionised by science. Thus, science understanding is an increasingly precious resource throughout the world. Despite the widely recognised need for better science education, the percentage of school students studying science is particularly low, and the numbers of students pursuing science continue to decline…

Science communication competence (SCC) is an important educational goal in the school science curricula of several countries. However, there is a lack of research about the structure and the assessment of SCC. This paper specifies the theoretical framework of SCC by a competence model. We developed a qualitative assessment method for SCC that is…

Teachers' professional knowledge is assumed to be a key variable for effective teaching. As teacher education has the goal to enhance professional knowledge of current and future teachers, this knowledge should be described and assessed. Nevertheless, only a limited number of studies quantitatively measures physics teachers' professional…

We report on a concept inventory for special relativity: the development process, data analysis methods, and results from an introductory relativity class. The Relativity Concept Inventory tests understanding of relativistic concepts. An unusual feature is confidence testing for each question. This can provide additional information; for example,…

University science teachers' technological pedagogical and content knowledge (TPACK) is crucial for effective teaching. Although there has been a plethora of studies investigating pre-service and in-service teachers' TPACK, few studies have examined university instructors' TPACK and university students' perceptions of instructors' TPACK. The main…
