Although residues and resource shortages are major problems of modern living, these topics are not usually properly covered in university curricula. To tackle this situation, we have guided undergraduate students through the design of a group of active learning activities, to demonstrate the science behind separation and recycling: trash…

Tungsten oxide semiconductors are used to photooxidize water. Students prepare WO3, CuWO4, and mixed composition thin film photoanodes. The syntheses are simple, allowing for the quick production of a range of materials. Photoanodes are tested in a photoelectrochemical cell assembled from common equipment, allowing for the direct comparison of…

The Briggs-Rauscher reaction is a popular demonstration to illustrate chemical oscillations in laboratories, classrooms, and public seminars because of its simplicity and visual appeal. Here, we adapt the Briggs-Rauscher reaction to present reaction-diffusion-convection patterns in the undergraduate general or physical chemistry laboratory. By…

Examining students' inclinations to use algorithms and rules to solve a task was a fruitful area of research in chemical education in the last four decades. This research aimed to examine whether students read the task request carefully, considering its meaningfulness, or they approach it mechanically, applying a set of algorithms by default. The…

Society at large often incorrectly thinks that the word 'chemicals' implies danger, when of course all matter can be described as a chemical. In this article we define what precisely we mean by 'hazard', risk' and 'danger'; we then consider selected elements from the periodic table that are noteworthy because of their dangerous characteristics.

The formulation of the periodic system by the Russian Mendeleev was followed by the surprising discovery of gallium by the Frenchman de Boisbaudran. The Englishman Ramsay's explanation of an 'impurity' in air led to recognition of a new period. A young fellow countryman, Moseley, justified the expected existence of 92 elements. A German couple,…

[NiBr[subscript 2](PPh[subscript 3])[subscript 2]] and [NiBr[subscript 2](dppe)] are prepared from nickel bromide hydrate and phosphine. These brightly colored coordination compounds are then converted into the related organometallic compounds "trans"-[NiBr(Mes)(PPh[subscript 3])[subscript 2]] and [NiBr(Mes)(dppe)] (Mes =…

Students with concealable identities, those which are not always visually apparent, must navigate the difficult choice of whether to reveal their concealed identities--a choice that has been found to impact an individual's psychological well-being. Research that gives voice to those with concealable identities is highly lacking, and subsequently,…

As science education faces the urgent task of rehumanization amid growing technocratic rationality, scientific eponyms, especially in literary contexts, offer a potential of rehumanization for value-based science education. To explore this potential, selected passages referencing the eponym "Landolt tables" from the short story…

Preliminary evidence regarding the effectiveness of a participation-based, formative assessment pedagogy in the laboratory component of undergraduate science classes is presented in this paper. The formative approach to teaching lab is unique in science education given the prevailing paradigm of summative assessment via grading lab reports. The…

This study contributes to discussions on facilitating students' sense-making in science by analyzing the utterances of high-achieving students in dialogues during practical work and identifying characteristics of their language use and learning processes. The context of the study is a general science course at an upper secondary school in Norway.…

This study explores multilingual study guidance (MSG) teachers design for learning and the potential of immersive and interactive Virtual Reality (VR) technology to support students' development of disciplinary knowledge through multilingual conceptual learning. Part of a co-design research project, the study draws on two teachers' didactical…

With the increasing technology integration practices in education, the adoption of computer simulations to teach conceptual understanding of science concepts is widely accepted by educators across the globe. To understand the connections between learners' engagement and satisfaction with simulations for science learning and their learning styles,…

The sudden COVID-19 outbreak has obstructed the conventional method of teaching causing a mandated shift to virtual platforms. A developing country like India which predominantly depended on conventional methods of teaching and learning in the pre-COVID era is gradually gaining success in effectively transitioning into virtual classrooms with the…

Student evaluations of teaching (SETs) are commonly used in performance evaluations of university faculty. However, evidence regarding the association of SETs to student learning has been inconsistent. One way to assess the connection between SETs and actual learning is to compare SETs in the first course in a sequence to student performance in…
