There are several ways in the literature to determine the value of gravitational acceleration. We used an audio plug (3.5-mm jack) that can be reused from types of plugs can also be purchased and are very cheap. In this article, a computer speaker or microphone that are damaged. These value of gravitational acceleration very accurately using…

The aim of this research is to identify pre-service science teachers' experiences during the simple electrical circuit establishment process, points they were challenged with, and developed strategies they used against the challenges they were experimenting with this process. In this study, embedded single case study, which is one of the…

In undergraduate classrooms, a majority of chemistry discoveries introduced are by white men and a small group of white women. There is greater online representation of chemists of diverse backgrounds, but the emphasis on diversity is mainly based on a monthly theme from Black History Month to Women's History Month. The "Diversity in…

Many academic institutions have looked at various ways to make their faculty a more diverse and inclusive group of people that better reflect the demographic swath of their current and future student bodies. This is even more so important in chemistry departments, where there has long been a discussion on the "leaky pipeline" for women…

Issues of diversity, equity, inclusion, and respect have a history at colleges and universities in the United States. Over 40 years ago, to address these issues at a large public university, the authors created a "tutorial program" (equivalent to a parallel educational system) that enabled a diverse cohort of students to succeed in their…

This study examined science teachers' attitude towards the use of mother tongue for instruction in Basic Schools, employing a descriptive survey design. The respondents were selected through purposive and convenience sampling techniques and data were collected from a sample of 162 Basic School Science. The questionnaire used for data collection…

The purpose of this research was to determine the effect of the 5E model on the understanding of the molecular genetics concepts taught in general biology. The research had a quantitative focus and a quasi-experimental design, and the participants were 40 undergraduate students from a private university in the west of Puerto Rico, which were…

While physics is often promoted as being for everyone, its cultural narrative, i.e., what physicists do and who they are, has been and continues to be created by a dominant social group. As such, many students who come from marginalized backgrounds in physics are required to fit themselves into its narrow culture that does not reflect who they are…

In the 1930s, the teaching staff of the University of Chicago devised a clever way to deliver experimental data to their introductory students without meeting them in the laboratory. The university's curriculum included a required Introductory Course in the Physical Sciences. There were probably too many students to allow for a standard…

Solar limb darkening is a prominent feature seen in white images of the Sun: the brightness of the solar disk is greatest at the solar center and decreases radially outward towards the limb. White light images can be used to examine and even model limb darkening; however, the limb-darkening effect is, in fact, wavelength dependent. Limb darkening…

As researchers, teachers, and practitioners we often encounter young professionals and lay adults who do not understand basics of mammalian body temperature regulation. Often their single solid piece of knowledge is that some vertebrates (mammals and birds) are warm-blooded and some (fish, amphibians, and reptile) are cold-blooded, which is…

This study aimed to determine the influence of critical thinking skills on misconceptions using a five-tier instrument in mixed-method research. The sampling technique used is simple random sampling. The data collection instrument used a critical thinking skills questionnaire, a misconception test of electric field material, and interviews. Data…

In this article, simple models of optical computing circuits (1 x 4 demultiplexer (DEMUX), 4 x 1 multiplexer (MUX), Boolean logic, and half-adder (HA)) are shown with mechanically controlled plane mirrors. Photographs of the proposed computational circuits are also shown. It is very useful for the school student to understand optical logic and…

The research aims to examine the effect of educational game activities on academic achievement in secondary school 5th -grade science lessons. The study group of the research consists of 71 5th-grade students studying at a public school in Turkiye in the 2017-2018 academic year. In the research, the pretest and post-test comparative design group,…

The Wilson cloud chamber, invented in 1911 by Scottish physicist Charles Wilson, is a remarkably simple and effective charged particle detector. Cloud chambers were used regularly in particle physics experiments for decades, until being supplanted by bubble chambers. In this article, we describe a lab activity that is suitable for…
