Dynamic biochemical processes are often difficult for students to grasp in the classroom using static images or models, or even through watching simulation videos. This is particularly true for protein-folding and enzyme catalysis, two key biochemistry concepts. The author has developed and tested two 3D, dynamic, and interactive classroom models,…

Recently, topical products advertising cannabinoid ingredients have gained popularity. Consumers are seeing an increase of commercial products containing ingredients from hemp oil to cannabidiol (CBD) due to health benefit claims. Cosmetic products containing cannabinoids are currently not regulated at the federal level. A laboratory experiment…

Although biochemistry is fascinating to undergraduates regardless of their major, the complexity involved requires a great deal of effort and leads many to perceive it to be an intense, facts-based course limiting personal creativity. This activity takes the fundamental knowledge associated with inducible promoters and combines it with the…

A flash purification system using prepacked cartridges containing different silica weights and particle sizes was employed to demonstrate the influence of column characteristics on chromatographic resolution. This chromatographic experiment was a helpful introduction to chromatographic courses where the influence of particle sizes was addressed…

Coagulation is an important process in the context of water purification; and the seed protein of the moringa tree ("Moringa oleifera") is a remarkably effective coagulant. The laboratory course described here is designed to provide high-school students with a stepwise, hands-on experience in investigating the protein-rich coagulant…

Practical work is widely seen as an integral part of school science. Research and teacher guidance have tended to consider practical work in science, rather than in individual science subjects or topics. This study used a questionnaire of selected- and open-response items to probe the views and reasoning of a sample of 43 pre-service teachers in…

This paper aims to review and assess the strategies available in literature to improve the practices of science process skills (SPS) among students. SPS encompasses the mental and physical activities of students in collecting and organizing information and then using the information to make predictions, explain phenomena, solve problems,…

Materials science research has expanded significantly in recent years; a multidisciplinary field, home to an ever-growing number of chemists. However, our general chemistry degree courses have not changed to reflect the rise in interest in this topic. In this paper, we propose a laboratory experiment for the undergraduate chemistry practical…

The time-resolved detection of very low intensity light emission has become an essential capability in many areas of science including molecular biology, fluorimetry, DNA sequencing, virus detection, nanoparticle research, and optical materials development. Among the most basic techniques for the detection of rapidly fluctuating low-intensity…

This report presents an interdisciplinary approach used in undergraduate laboratory classes to bridge the gap between scientific advances, engineering efforts, and practical applications in daily life. The field of biointegrated electronics is highlighted as an excellent opportunity for building interdisciplinary learning models, leveraging…

The COVID-19 pandemic, which emerged in early 2020, forced educational institutions in Thailand to chiefly rely on online learning during the government mandated lockdown for almost two academic years. Although migration to the online format seems to suit lectures, it is inadequate for laboratory courses since students could not do the experiment…

This report outlines an approach for preparing 5-color 3D printed plastic models of molecular orbitals and electron density surfaces using a hobby-grade 3D printer. Instructions are provided for preparing 3D orbital and electron density surface (EDS) models using solid or mesh representations in ground state and transition state structures. We…

In this quantitative study, we explored learners' intrinsic motivation towards three different experimental physics educational activities offered by our department to upper-grade high school students. The inspected activities were lecture demonstrations, a science show, and hands-on practical work. The respondents were Czech high school students…

Education is undergoing critical transformations driven by innovations in remote experimentation and learning analytics. As technology reshapes how we teach and learn, remote experimentation allows students to conduct hands-on, interactive experiments from anywhere in the world, breaking down geographical and resource-based barriers. This shift…

One of the tools middle school SBAE teachers can use to deliver the total program is research-based SAEs, for which students can receive recognition through the FFA Agriscience Fair. This study examined why middle school SBAE teachers implemented the FFA Agriscience Fair into their programs. This study built on previous literature in this area,…
