With the rapidly increasing demand for STEM skills, many scientists, mathematicians, engineers, and technology professionals encourage students to pursue STEM careers. However, communicating science to lay audiences is challenging due to complex scientific terminology. This qualitative research aimed to demonstrate how an exemplary scientist, Dr.…

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…

This paper reviews the current position of the history of education within the existing historiography of science and technology, and argues for the relocation of education from the periphery of the history of science and technology to its centre. It claims that it is essential to study science education in its entirety and complexity if we want…

Experimentation is a contributing factor to the interest and meaningful learning of Science. In Geology and Earth Science, the effects of soil textures, settlements, and water-holding capacity are parameters for landslides in Barotac Viejo and other flooded areas. Landslides are triggered during heavy rainstorms, causing severe property damage and…

Science centers, despite their growing popularity (Association of Science and Technology Centers [ASTC], 2022), have diversity, equity, and inclusion (DEI) concerns (Garibay & Olson, 2020) that threaten the achievement of their mission (Feinstein & Meshoulam, 2014) and the very utility of their existence (Ash 2022; Dawson, 2019). The…

An active-learning approach was employed in a project for our chemistry major students on the synthesis of biodiesel (BD) from an Amazon region oil. The project, involving activities in class and in the laboratory, was given during 8 weeks of the spring semester of 2022. The students were asked about their previous contact with the synthesis and…

We have developed a guided-inquiry laboratory exercise in which students perform viscosity measurements to infer the structure of poly(vinyl alcohol) (PVA) in aqueous solution. The activity combines both experiments and modeling. In the experimental portion of the exercise, students measure the viscosity of several solutions of PVA with differing…

Electrophilic aromatic substitution reactions are common in the organic chemistry laboratory. These reactions, while ubiquitous, use corrosive reagents and halogenated or hydrophobic solvents that produce expensive and hazardous waste streams. The carboxylation of phenols (Kolbe-Schmitt reaction), although aqueous, typically involves conditions…

Electrochemistry is taught in most undergraduate chemistry programs. Although this topic is important for students due to its broad interest in industry (energy, diagnostics, car industry, etc.), they often find it difficult, because it is based on a combination of various physical concepts such as electric fields, interfacial processes or charge…

Experiments serve different purposes in chemistry education ranging from illustrating a certain subject matter to providing data for school-based research projects. When students use these experiments to collect data and draw conclusions, it is important that these experiments are valid. In this study, a new experiment for the determination of the…

The particle-in-a-box experiment is a well-known method used to teach quantum mechanics concepts in physical chemistry laboratories for undergraduates. The investigation involves measuring the wavelength at maximum absorbance ([lambda subscript max]) of electronic transitions in the UV-vis spectrum and linking it to the box length. As the…

The UV--vis absorption of cyanine dyes is a common experiment in many physical chemistry teaching laboratories. As part of the analysis, students are often asked to hypothesize why the predicted absorption differs from the measured values and why dyes which are predicted to have the same absorption have measured values which differ from each…

In school chemistry, the oxyhydrogen or "Knallgas" reaction is used to provide evidence of hydrogen gas in the squeaky pop test. However, the test actually indicates the presence of an explosive gas mixture of hydrogen and oxygen (oxyhydrogen gas) rather than pure hydrogen. The sheer observations of an explosive reaction and the…

For the past decade, the College of Chemistry at UC Berkeley has iteratively redesigned general chemistry laboratory courses to introduce students to green chemistry concepts, while simultaneously using green chemistry as a relevant context to learn chemistry. To investigate the effectiveness of this curriculum we developed approaches to…

The study aims to design a socio-scientific issues (SSIs)-based electronic learning (e-LM) design framework. It is anchored to the SSI occurrences in teaching Science at a State University in Batangas province, Philippines. This SSI-based e-LM design framework will guide the e-LM development for teaching Science socio-contextually through flexible…
