A study on the misconceptions developed or held by teachers related to the two terms valence and valency was undertaken. A total of 48 teachers (26 males and 22 females) teaching the chemistry component of science subject to 14-16-year-old students, in 48 schools affiliated to one district, were randomly selected for the study by taking one…

Video motion analysis allows tracing trajectories of objects in motion and is an established method in physics education. Tablet computers, with their integrated cameras, offer the opportunity to both record and analyze dynamic motions during experiments on a single device. This enables students to work without transitioning the data between…

Quantum computers are at the forefront of computing; however, few people understand how they work and their capabilities. We present two versions of an interactive activity designed for high school students (ages 13 to 18) that introduce a core quantum concept--"entanglement." The first version illustrates a simple connection between two…

At Race Leys Junior School in Warwickshire, creative and unique experiences are at the forefront of the minds of the teachers. As a team, the teachers are always seeking new and innovative ideas to enrich their curriculum. Over the last year, through the COVID-19 pandemic, they have become more adventurous with their thinking and lesson delivery.…

In the epidemic period, online teaching has become the most important teaching form. On the basis of questions-centred massive open online courses (MOOCs) teaching, the online teaching mode of college physics was studied and discussed using the Tencent classroom, WeChat/QQ and Wisdom Tree Platform. MOOCs before class, Tencent classroom during…

Research has identified several students' misinterpretations of the principles of the photoelectric effect (PE). Students cannot interpret the formula using the graph's context despite the linear dependence inherited in it. Many studies pointed out that the graphical representation of kinetic energy of the ejected electrons versus frequency of…

The aim of this study is to comparatively investigate the effects of hands-on models (HMs) and computer simulations (CSs) on teaching the phases and eclipses of the Moon. In this study, two different HMs were developed, and three different CSs were used. The research work group consisted of 100 pre-service science teachers. A quasi-experimental…

One broad research question researchers continue to pursue is: to what degree does science teacher education influence the thinking of preservice science teachers? In other words, how has the thinking of preservice science teachers changed during the course of teacher education? Different models of cognition suggest different foci for this…

The purpose of this quasi-experimental research was to reveal the JiRQA learning supports on biology students' achievement in the multi-ethnical classroom in higher education. The research sample was included 125 students consisting of the ethnics of Dayak, Javanese, and Malay. The achievement data were obtained from the pretest and posttest using…

[superscript 1]H NMR spectroscopy is a molecular characterization technique that is ubiquitously used in research and teaching laboratories alike. Strategic deuteration of molecules is a commonly employed technique in the deconvolution of [superscript 1]H NMR signals. Here this approach is applied in a second-year chemistry course in which…

In this systematic review, we investigated how content knowledge (CK) and pedagogical content knowledge (PCK) in the domains of mathematics, science and literacy are represented in current research regarding early childhood pre- and in-service teachers. In our systematic literature search, we found 151 publications, of which 42 remained in the…

Understanding genetics is one of the most significant learning difficulties faced by students. To improve teaching genetics and the students' representational competence within the classroom have been proposed using multiple representations. This study presents an analysis of representational levels used by high school students learning Mendelian…

Motivated by often passingly brief textbook discussions of industrial capacitors, this study examines how students make sense of textbook descriptions to create an industrial rolled-up capacitor. A total of 37 junior-year students at a top high school in Beijing, China, participated in the study. The participants followed their textbook guidance…

Recent science education reforms, as described in the "Framework for K-12 Science Education" (NRC, 2012), call for three-dimensional learning that engages students in scientific practices and the use of scientific lenses to learn science content. However, relatively little research at any grade level has focused on how students develop…

This paper illustrates the role of metalanguage in an explicit literacy instruction to talk about the forms and functions of scientific genres, particularly the genre of explanation. In the context of science, metalanguage refers to the technical terms for talking "about" scientific language using words like law, hypothesis, and…
