This communication describes a variety of virtual student assessment strategies employed at the University of Toronto during the academic disruption caused by the 2020 COVID-19 global pandemic. Instructors focused their efforts toward maintaining a positive learning environment and offering meaningful evaluation methods for students in each of…

The switch to distance learning as a result of the COVID-19 pandemic has required chemistry instructors to quickly adapt and innovate to provide remote instruction as effectively as possible. With minimal advance notice, developing and delivering online lecture materials that are engaging and laboratory activities that approximate a hands-on…

Chemical reactions far from equilibrium can exhibit oscillatory behavior. Full understanding of this phenomenon is outside of the school curriculum. However, the importance of such processes in life sciences and peculiar spatial and temporal patterns accompanying the reactions can attract the attention of IB Diploma science students. They will…

The rhetorical argument that laboratory courses are crucial for training skilled STEM practitioners is ill-evidenced in teaching practice. The arduous task of implementing instructor-led skill assessment in large-cohort courses and persistent student "disengagement" from its educative goals are some obstacles. This study emphasized the…

While science self-concepts of secondary school students have received considerable attention, several important aspects of chemistry self-concepts have not yet been understood: gender relations, the impact of students' cultural backgrounds, and the impact of chemistry self-concept on learning processes. In the present study, (i) we could confirm…

The results of an earlier empirical research study on modifying 'step-by-step' instructions to practical activities requiring one or more steps of the experiments to be designed by students initiated a longitudinal study to investigate the effectiveness of the approach for younger students and over a period of time. The longitudinal study that…

Chemists refer to chemical phenomena on different representational levels--macroscopic, symbolic, and submicroscopic--which are directly related and connected to each other. Especially in the laboratory, students have to reason about various mechanistic features at the submicroscopic level and connect them in a meaningful way to make sense of the…

This mixed-method study examined the influence of metacognitive awareness on the change in preservice chemistry teachers' understandings of gas behavior in the context of multirepresentational (MR) instruction. The goal was to describe the types of understanding of gas behavior held by a group of participants with high metacognitive awareness (MA)…

Using virtual reality (VR) in educational settings is becoming increasingly popular. The feasibility of replacing an instrumentation-based organic chemistry lab with a VR experience has been evaluated. A VR laboratory experience was designed to teach students how to use an infrared spectrometer and elucidate an unknown structure from the resulting…

At the University of Applied Health Sciences, the iPad tablets are used at the undergraduate professional study programs Environmental Health Engineering and Laboratory Medical Diagnostics as part of the practical classes in Biology and Chemistry. Four applications are used within the framework of the unit titled "Preparing Solutions",…

The Yuan T. Lee Foundation Science Education for All (YTLF) has implemented a science camp for students with visual impairments in central Taiwan since 2009. The implementation of the camp serves as an informal science education practice model that informs curriculum design and development, personnel preparation and organization, as well as…

Chemical educators are facing a new generation of instructional technologies that impact classroom teaching. New technologies, like smartphones, cloud computing and artificial intelligence take learning beyond the classroom; 3D printing, virtual reality, and augmented reality provide new ways to teach the virtualization skills that are important…

Aim/Purpose: The objective of this study is threefold: (i) investigate how a group of subjects see the relationship between the integration of content, pedagogical and technological knowledge of their chemistry teaching in light of the teaching practices developed during the pandemic; (ii) present a framework for the integration of digital…

This laboratory experiment employs an innovative approach to introduce undergraduates to liquid chromatography-tandem mass spectrometry (LC-MS/MS) by developing a method based on multiple reaction monitoring (MRM). During this qualitative investigation, students operated a triple quadrupole mass spectrometer in the MS scan and product ion scan…

An iridium(III)-mediated C-H functionalization sequence involving a concerted cyclometalation-deprotonation/migratory insertion pathway is reported for the undergraduate chemistry laboratory. The air- and water-stable iridacycle intermediates are readily isolated and characterized by NMR spectroscopy. Both steps of the experiment are performed at…
