The COVID-19 pandemic posed significant challenges for practical teaching within the sciences. While many instructors adopted innovative alternatives to conventional practicals, many relied on digital approaches that did not give students hands-on experience. In this study we evaluate the use of 'at home' practical kits used in first year physics…

Teachers' conceptions of teaching play a key role in the pedagogical practices they apply in their teaching. Previous studies of conceptions of teaching generic skills have been mainly qualitative with small samples, and thus there is a need for a more extensive quantitative study. This study investigates the associations between higher education…

Research on teacher educators' professional learning has gained increasing interest within science education. Curriculum materials have been suggested as a means of supporting "teacher" learning for several decades but have not yet been examined as a potential tool for supporting the learning of "teacher educators." In this…

In this paper, the authors focus on theoretical discussions regarding the socio-scientific issues based exhibition, whose importance has become greater for science centers in the past two decades, but has no clear definition. We examine the background of the socio-scientific issues based exhibition, including its scope and qualities, through…

Why does a raindrop on a window pane show an image of the environment that is turned upside-down? And why does vision go blurry underwater, but is perfectly clear with diving goggles? Our everyday life is rich in optical phenomena. Unfortunately, these phenomena often play a subordinate role in Optics teaching, compared to ray constructions or…

This article focuses on "uncertainty"--ways in which scientists recognize and analyze limits in their studies and conclusions. We distinguish uncertainty from (un)trustworthiness--ways in which scientific reports can be affected by conscious deception or unconscious bias. Scientific journal articles typically include analyses and…

A solenoid is a coil wound many times on a cylinder of length greater than its diameter. Solenoids are mainly used as electromagnets, because a magnetic field is formed when current flows through a solenoid. The solenoid described in secondary school and university textbooks is a single-layered solenoid. Further, textbooks and papers focusing on…

The direct involvement of students in conducting experiments in order to learn science has been a common part of U.S. educational practice since the late 19th century, the result of the rapid spread of what was known as the "laboratory method" of teaching. Those promoting the laboratory method recognized it as a new educational approach,…

The Physics Teacher has published over the years many inspiring papers with an historical slant and we agree with Thomas B. Greenslade, who recently wrote that teaching physics is about "integrating physics with human culture.… if we are going to leave a lasting impact on our students, we should do more than teach them pure physics."…

In this paper we discuss the types of knowledge used by six middle school students as they engaged with a debugging task designed to integrate ideas from computer science, mathematics and science. Our findings show that the computational thinking practice of debugging is a rich source of opportunities to integrate these different disciplines. The…

Transformational equity-centered science education requires the fields of science education and school leadership to critically consider the limited preparation elementary principals are offered to lead for science education. Thus far, little effort has been made to foster a transdisciplinary curricula beyond traditional organizational theories…

This case study examines students' perception, motivation, and learning gain of a teaching unit featuring wireless sensors as tools to collect scientific data in the classroom. Students analyze data using the corresponding cellphone app, communicate findings to the class, and learn about a changing environment. Wireless sensors are produced for…

This mixed-methods study reports the results of a survey completed by a sample of Puerto Rican social and natural scientists (STEM-S) regarding their perceptions of the intersectionalities of racism, colorism, colonialism, and the culture of science. Most participants ranked themselves as light-skinned and were familiar with the racist stereotypes…

The ultimate aim of this research was to explore the contribution of teacher preparedness or readiness (in terms of their academic background, confidence in teaching science and career satisfaction) towards the achievement in science among Malaysian and Singaporean eighth-graders. The TIMSS 2011 international assessment of student achievement at…

This article focuses on the learning of the Lewis representation at the transition from high school to university, in France. Indeed, this notion is taught both in high school and in the first year of higher education but with different methods, which seems to hinder the learners. In this work, we observe 11th grade and higher education classes…
