The Folch method is a commonly employed, simple biochemical procedure used to extract fat from food items and biological samples in biochemistry laboratories. The iodine number of fat reflects its degree of unsaturation. In the present study, the iodine number of fat extracted using the Folch method from cow milk, goat milk, chicken egg yolk and…

Laboratory safety regulations have been traditionally viewed by its learners and practitioners as a matter of law and policy, which simply requires compliance. A compliance mindset tends be passive and dissociates individuals (or even institutions) from the important reasons and principles underlying the safety rules and regulations, leading to…

Bacteria have developed a cell-to-cell communication system called quorum sensing (QS), allowing them to regulate group behavior and synchronize the expression of virulence factors, responsible for increasing their infection capacity and resistance to antimicrobials. Although the control of microbial infections through the inhibition of microbial…

The ability to elucidate the structure of organic compounds from their nuclear magnetic resonance (NMR), infrared (IR), and mass spectrometry (MS) spectra is an essential skill, particularly for those engaged in the fields of synthetic and analytical organic chemistry. Spectral analysis constitutes a fundamental component of the curriculum for all…

The subject of pharmaceutical research has traditionally focused on drugs with systemic effects. However, contemporary approaches aspire to achieve targeted drug delivery, with the aim of combatting infections with a precise immune response. Active substances are encapsulated in nanoparticles, transported through the body, and selectively released…

We present the development and evaluation of "da Vinci's Curse", a chemistry escape room experience designed to consolidate laboratory skills in a fun and interactive setting. Inspired by the maestro, Leonardo da Vinci, the escape room challenges students to complete a series of puzzles in teams to escape "da Vinci's Curse".…

Affect and emotions matter to science learning. They also matter because they are integral to science identity formation and sense of belonging. This study aims to foreground the epistemic and affective character of laboratory work in higher science education by conceptualizing it as epistemic practice, in which students activate their body and…

The biology laboratory at State Senior High School (SSHS) 1 of Rasau Jaya has not been fully utilized, necessitating evaluation and improvement. This study aimed to determine the suitability of laboratory facilities and infrastructure at SSHS 1 of Rasau Jaya in relation to the existing standards set by the national regulations. This is a…

This study describes the process of developing a high-impact, low-cost, and low-maintenance air ventilation system for anatomy facilities. It employed the strategic application of Value Engineering (VE), assuring that the air ventilation system meets contemporary threshold limit values (TLVs) for formaldehyde in the working zone of dissection…

The COVID-19 pandemic was an unprecedented event that, out of necessity, drastically changed the way undergraduate chemistry courses were taught. With the cancellation of in-person classes, laboratory experiences were delayed and/or moved to the virtual space, the latter keeping the general framework of the laboratory experiment but removing the…

Purpose: Hands-on training in tissue engineering is often associated with specialized labs and expensive equipment, such as CO[subscript 2] incubators. To minimize the use of costly commercial incubators and provide a more vivid engineering experience in a biology lab, we present a hands-on project that introduces medium to large groups of…

NMR prediction using ChemDoodle, NMR calculation with Gaussian, and hands-on data collection using a benchtop NMR spectrometer were explored to assess their synergistic capacity in teaching NMR to organic chemistry students. Nine molecules representing functional groups commonly encountered in undergraduate organic chemistry were selected. Spectra…

Background: Given the increased emphasis on active learning in psychology, it is important to use data to enhance these experiences. In learning courses, both live animals and virtual training laboratories have been found to enhance learning, but less research has examined student preferences. Generally, live rats are preferred, but students may…

The objective of the study is to assess the effectiveness of laboratory activities employing the Predict-Explain-Observe-Discuss-Explain (PEODE) approach in promoting gifted students' interpretation of everyday problems related to fundamental science concepts. This quasi-experimental study involved 54 gifted students enrolled in the Science and…

Traditional didactic teaching methods in medical education, while foundational, often lead to passive learning and insufficient engagement. "Pancreata--The Keto Struggle," an educational tale-based game for diabetic ketoacidosis (DKA), was developed to address these challenges by promoting collaborative learning, enhancing student…
