Purpose: Blended learning is an emerging trend across many educational settings, adopting the purposeful integration of traditional face-to-face and online teaching to establishing an engaging learning experience for the students. Blended learning provides an ideal platform for the implementation of reusable learning objects (RLOs) as a…

Information overload and limited laboratory time usually result in students focusing mostly on procedural tasks to get the results, rather than being engaged with what they are doing. Moreover, traditional laboratory curricula rarely provide students opportunities to repeat experiments. This study presents the design of a web-based application…

As a result of the COVID-19 disruption experienced in Spring 2020 many institutions had to close their doors and move their courses online. Our team used an existing set of virtual reality (VR) organic chemistry laboratory experiences developed for students with accessibility challenges as an online replacement for the face-to-face Organic…

The COVID-19 outbreak has altered chemistry laboratory instruction and forced us to reconsider the balance between face-to-face and online teaching. Our students preferred face-to-face teaching (score 4.1/5 on a Likert-like scale) to virtual laboratory exercises (3.4/5) despite the fact that their performance score was actually lower in…

Classes, as a critical teaching-learning process in the school culture, remain, essentially and for the most part, without fundamental changes, following the sequence: presentation of the contents by the teacher, and implementation of these contents in a very theoretical way (highly based on the resolution of exercises, either through worksheets…

Formative assessment benefits both students and teaching academics. In particular, formative assessment in mathematics subjects enables both students and teaching academics to assess individual performance and understanding through students' responses. Over the last decade, educational technologies and learning management systems (LMSs) are used…

Here, students determine the total phenolic content in beers using the Folin-Ciocalteu assay. The Folin-Ciocalteu reagent is a yellow complex, in an alkaline medium; it reacts with phenols and non-phenolic reducing substances to form a blue complex. Quantitative analysis was carried out using absorbance measured at 765 nm (standard method) and…

Smartphone technology has the potential to make heritage science accessible to museums, individual collectors, and educators. Infrared reflectography (IRR) is a nondestructive analysis method used by museums to gain information about the provenance, history, and aging of artworks. This paper introduces a highly accessible, inexpensive apparatus…

This paper describes a number of active learning strategies based on implementing the Raspberry Pi as low-cost single-board computing device for carrying out physics laboratory activities. This Microcomputer-Based Laboratory (MBL) Project has been funded by the Baden-Württemberg Foundation and it encompasses the use of high-accuracy yet…

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…

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 angular velocity of a spinning object is, by standard, measured using a device called a tachometer. However, by directly using it in a classroom setting, the activity is likely to appear as less instructive and less engaging. Indeed, some alternative classroom-suitable methods for measuring angular velocity have been presented. In this paper,…

KinSim is a research-grade, interactive, user-friendly, open-source, and visual software for kinetics modeling of environmental chemistry and other applications. Students without any computer-programming background and limited knowledge of environmental chemistry can use KinSim, which also includes multiple features and functionality dedicated to…

At the University of South Australia (UniSA), Biochemistry is a second year undergraduate course. The student cohort is diverse, with students enrolled in courses with a laboratory focus, such as Laboratory Medicine, Medical Science, Nutrition and Food Science and Pharmaceutical Science. The course is taught in a traditional manner, with weekly…

The distance teaching of organic chemistry to first-year undergraduate students during lockdown represents a challenge for both students and teachers. To face this challenge, a method combining synchronous and asynchronous teaching was presented in this paper. The asynchronous part of the teaching was achieved through the broadcast of videos on…
