Traditional laboratory courses involve students following detailed weekly experimental procedures, culminating in either a laboratory report or handout at the end of each experiment. While this setup teaches basic laboratory skills, it usually does not encourage students to think critically or independently. Therefore, many laboratory instructors…

Investigating student engagement in active learning activities could provide valuable insight into variations of student learning outcomes when active learning is included in a course. This study sought to explore students' engagement in relation to active learning activities incorporated in a general chemistry lecture course using the Activity…

The high demand for N95 and surgical masks made of nonbiodegradable petroleum-based materials due to SARS-CoV-2 challenges the recycling industry and is proving to be unsustainable. Although woven fabric masks present a longer lifetime, they are less effective in protecting against viral particulates. Here, through an at-home course-based…

With the benefits of low cost, energy efficiency, and environmental protection, photocatalytic hydrogen production is considered to be the most promising technology for the development of a clean and sustainable society. However, the utilization of photocatalytically generated hydrogen is not very common yet. Therefore, tertiary education urgently…

With the development of a strong bioeconomy sector related to the creation of next-generation biorefineries, heterogeneous catalysis is receiving renewed attention. Indeed, catalysis is at the core of biorefinery design, and many new catalysts and catalytic processes are being developed. On the one hand, they are based on knowledge acquired during…

The application of charcoal to soils to increase carbon stocks has been of great interest recently. To gain a better understanding of the long-term effects of charcoal presence in soils, historic charcoal production sites at Catoctin Mountain Park, Maryland were studied for organic carbon content and compared to nearby unaffected soils. Soil…

This study was conducted to determine the effectiveness of virtual laboratory based on semi second life (s-SL) on higher order thinking skills of general senior secondary school in chemistry learning process. The research design was adopted posttest only design approach to a quasi-experimental. This study was conducted in the one of public general…

A practical for students to experience a process plant is presented, based on operating a solvent absorption plant for carbon dioxide capture. The student must operate the plant in assigned roles that closely identify with a chemical plant environment, to achieve specific performance targets. Students must overcome technical challenges that…

Research has shown that spatial ability plays a key role in understanding STEM (Science, Technology, Engineering, and Mathematics) content, including chemistry. Conservation of Matter (CoM) is an essential but challenging topic for chemistry students of all ages to grasp; it is often taught in a way where students memorize it but do not learn what…

Laboratory safety is a vital part of a chemical education and can be incorporated into courses throughout the chemistry curriculum. Discussions of laboratory safety can serve as an introduction to the important field of green chemistry. Exposure to this field can better prepare students for safer and more sustainable laboratory practices in…

This research aims to explore the effectiveness of using computer-assisted games as a learning media to improve the quality of learning in Chemistry. The research was conducted in Indonesia on high school students in three separate classes or groups, in three separate schools that were randomly selected. There were three stages of data collection…

This communication was to share the efforts made in developing the fully online courses in medicinal chemistry during the educational disruption due to the coronavirus disease 2019 (COVID-19) pandemic. In the academic year 2020, the online course was implemented for the first time at the Faculty of Pharmacy, Silpakorn University, Thailand. Various…

Thomas Graham discovered the law that bears his name while studying gas diffusion into air and other gases. He also found that the same relationship held with gas effusion, the movement of gases through a pinhole into a vacuum. Modern understanding of diffusion and effusion is based on kinetic-molecular theory, and it is generally accepted that…

Language and argument are epistemic tools that learners can use to help them generate and validate knowledge for themselves, as emphasized in NGSS and previous NRC reports. Not all learning environments elicit or support the use of these epistemic tools equally, thus affecting how students grow in competence in relation to their use. The present…

Despite the substantial progress made to develop evidence-based pedagogical practices that support student learning, many courses are dominated by "traditional" practices such as a passive lecture. Thus, a continued focus on reforming courses is necessary. Here we describe the deliberate practice-driven reform of a large lecture-format…
