Working with approximations is a common practice in physics. This paper presents an exploratory study of student understanding of some of the elementary aspects of approximations encountered in college physics. For this purpose, a questionnaire (a set of 14 multiple-choice questions) was developed to probe how students dealt with these aspects in…

Green School Programs are an internationally recognized effort that transforms schools into environmentally friendly entities and engage school communities in environmentally impactful efforts. Such efforts may increase student awareness about their connection to the environment and have the potential to increase achievement through opportunities…

Single-molecule localization microscopy (SMLM) has revolutionized our ability to visualize cellular structures, offering unprecedented detail. However, the intricate biophysical principles that underlie SMLM can be daunting for newcomers, particularly undergraduate and graduate students. To address this challenge, we introduce the fundamental…

Many undergraduate chemistry and biochemistry students pursue careers in healthcare. Biomaterials, designed to harmonize with the complexity of the human body, have become increasingly significant in medicine as implants, drug delivery vehicles and tissue scaffolds. We believe it is essential that undergraduates are exposed to biomaterial…

The main purpose of this study is to determine the effect of using a new type of mnemonic device, utilizing dance steps in teaching Chemistry 7 in the retention rate of students on the properties of metals and non-metals. Different dance mnemonics corresponding to each property of the two types of elements were developed by the researcher. It was…

As part of learning to teach, teachers must learn to use a range of teaching practices. In this longitudinal study the authors explore how novice elementary teachers learn to engage in a set of high-leverage science teaching practices, such as "leading a science sensemaking discussion" and "setting up and managing small-group…

Background: Blended mathematical sensemaking in science ("Math-Sci sensemaking") involves deep conceptual understanding of quantitative relationships describing scientific phenomena and has been studied in various disciplines. However, no unified characterization of blended Math-Sci sensemaking exists. Results: We developed a theoretical…

Contributed data reflective of students' compliance in doing electronic homework (e-HW) exercises when asked to choose when required e-HW assignments are due are evaluated using a quasi-experimental format with non-equivalent groups to determine if first-semester general chemistry (Chem I) students (N = 273) will academically benefit from improved…

Transcription is the critical first step in expressing a gene, during which an RNA polymerase (RNAP) synthesizes an RNA copy of one strand of the DNA that encodes a gene. Here we describe a laboratory experiment that uses a single assay to probe two important steps in transcription: (1) RNAP binding to DNA, and (2) the transcriptional activity of…

Background: Effective science teaching requires a specialised body of knowledge. Researchers have recognised the importance of understanding the incoming knowledge that pre-service science teachers (PSTs) bring to their initial teacher education. However, although many studies have focused on PSTs' declarative knowledge or the knowledge that…

Intercultural teaching practices for science education (ITPSE) are suitable to support science teachers in bringing cultural inclusion into their classrooms. The epistemological bridge is the base of the ITPSE design since this approach describes culturally inclusive teaching of science. There is an ITPSE of planning and one of enactment. With…

Nature of science (NOS) is considered an important component of scientific literacy. Supporting students to develop a comprehensive NOS understanding is one of the most commonly described objectives within science education. Moreover, history of science can arguably provide a good context for NOS teaching and learning; it has been suggested that…

Electrostatic force is the preliminary and fundamental topic that forms the bedrock on which the conceptual framework of "electromagnetism" is built. Being a 'vector' quantity, electromagnetic force naturally inherits direction as well as magnitude. The conceptualization of such physical quantities may pose a challenge. The present work…

We present a new secondary school teaching method of quantum uncertainties of two-state systems. Intending to be a material teachable in schools, only two-state systems described by real numbers can be considered. An elementary argumentation based on school statistics leads to the identification of the uncertainty of a physical quantity in such…

The aim of this study was to determine the effect of student-centered practices in a life science course at the national level. In line with this purpose, searches were conducted in the identified databases. This meta-analysis study employed 39 experimental studies (48 comparison data sets). Upon completing the analysis, it was observed that the…
