We describe here a 4 hour experimental session based on reaction monitoring of the degradation of an organic pollutant via a Fenton-like reaction. An aqueous solution of p-nitrophenol is treated with hydrogen peroxide and magnetite, and the progress of the reaction is monitored by UV-vis spectrophotometry and/or gas chromatography using an…

Science process skills are the backbone of science, and innovations in this field. It is critical to inculcate such skills among learners at their early stages of learning science. This study reports on how using the mobile phone WhatsApp-supported instructional resources resulted in improvement in students' science process skills in chemistry, in…

The aim of this research is to take a fresh look at the physical science concepts that Year 3 students struggle with. In this work, the responses of over 8,000 middle-primary-aged students to a range of physics, space science and chemistry questions were evaluated. The questions covered a number of topics ranging from selecting and using simple…

This study adds to the growing body of research on laboratory work. The study involves four pairs of students in a university introductory calorimetry lab of which two pairs, the IR-pairs (infrared camerapairs), were given access to infrared cameras to use however they liked during their course lab work. Two other pairs, the T-pairs…

A straightforward protocol for the preparation of the colorful and air-stable diphenyl ditelluride is described. In one laboratory session, students isolate their product and characterize it via melting point determination, mass spectrometry, and NMR spectroscopy ([superscript 1]H, [superscript 13]C­{[superscript 1]H}, and [superscript…

Chemical kinetics is a branch of physical chemistry that constitutes an essential part of undergraduate education. In general, a complex and expensive experimental apparatus is indispensable for observing the kinetics of a chemical process owing to the continuity of chemical reactions. Thus, intuitive visualization of the chemical kinetics using a…

Owing to the global spread of the coronavirus disease 2019 (COVID-19), education has shifted to distance online learning, whereas some face-to-face courses have been resumed with the improvement of the outbreak prevention and management situation, including a laboratory course for senior undergraduate students in chemical biology. Here, we present…

At-home chemistry experiments are increasingly important to enable high-quality online and hybrid instruction. These class modalities provide significant challenges and also dramatically expand the accessibility of education to those who work or care for family during traditional school hours or have significant commutes to campus. This work…

Background: Training both pre - and in-service teachers who are capable of planning and enacting engineering design-based science instruction are critical for integrating engineering into K-12 science curricula. Purpose: This study investigates pre-service teachers' efforts to integrate engineering into their lesson plans. Sample: 13 pre-service…

International science education reforms seek to support teachers in using everyday assessment to draw out and work with student ideas; however, developing these instructional practices requires time and support. This paper investigates how a professional development program supported high school chemistry teachers to learn about formative…

Researchers and educators have been exploring systems thinking (ST) in chemistry education to better equip citizens for 21st century challenges; however, little is known about students' perspectives and experiences. In this study, we investigated students' perspectives of ST and their experiences with ST activities. We designed and implemented a…

This study revamps and optimizes the teaching and learning process and instrument for the classic binary vapor-liquid equilibrium experiment by combining activity coefficient model simulations and practical exercises. Our teaching process combines a software simulation and practical exercises. Utilizing Aspen software, students can predict phase…

A large number of students across the globe each year enroll in general chemistry courses as an academic requirement to obtain their degree. Although many take chemistry courses, it is not a subject sought out by many as a potential career. In some instances, chemistry hinders students from achieving their career goals. A plethora of chemical…

Polymer chemistry is an important subject in the undergraduate chemistry curriculum. It is required for ACS-certified degrees and significantly connects to real world issues like the plastic waste crisis. While some concepts of polymer chemistry can be incorporated into lecture courses, students' understanding of material properties and…

Owing to the critical role of stereochemistry in biotechnology, medicine, and industry, it must be well represented in undergraduate lab curricula. To achieve these stereochemical laboratory requirements without sacrificing existing lab techniques, we modified two standard laboratory experiments to include chiral GC analysis as follows. (1) The…
