This study expanded the "cell agglutination reaction" experiment in undergraduate cell biology teaching by integrating a sugar inhibition component. Lectins bind to specific sugars. In the traditional cell agglutination reaction, lectin is used to cause cells to aggregate via binding to sugars present on the cell surface. Here, various…

Owing to factors such as poor water solubility of luminol and the instability and easy decomposition of hydrogen peroxide (H[subscript 2]O[subscript 2]), the accuracy and sensitivity of the detection of H[subscript 2]O[subscript 2] through the luminol electrochemiluminescence (ECL) system are limited. Herein, we propose a water-soluble…

Spectroscopy is an integral part of chemical research, and the operation of any spectroscopic instrument is critical in chemical education. This study presents a low-cost, do-it-yourself (DIY) style spectrophotometer system that can be adapted for UV--vis spectrophotometry, fluorimetry, and atomic emission spectroscopy applications. The DIY system…

Some researchers have theorized that emotions while reading science texts influence learning in a wholistic way, such that overall positive or negative affect leads to different learning outcomes. Other researchers have envisioned that emotions fluctuate during reading such that the degree of cycling impacts the learning outcomes. In this study,…

Laboratory experience is vital to undergraduate science education. It allows students to observe and conduct engaging experiments to enhance their skills and literacy, helps them retain knowledge, and deepens their understanding of related content covered in lectures. This paper reports a 4-week undergraduate laboratory exercise on…

Paal--Knorr reactions are a classical method for synthesizing pyrroles, using 1,4-dicarbonyl compound and amine as reactants. It has the characteristics of green chemistry, as only two molecules of water are lost. In this teaching and learning experiment, 2,5-hexanedione and 4-"tert"-butylaniline were used to synthesize…

Science educators face significant challenges in preparing learners with the skills and knowledge necessary for 21st-century functional scientific literacy. This stems from high expectations of students and a growing demand for them to apply their learning to complex issues with political, social, environmental, and economic dimensions. The…

Recent efforts to make undergraduate biology more inclusive include developing content that explores how human values and priorities impact science, and previous work documents how instructors value an "ideologically aware" biology curriculum that highlights these themes. Here, we surveyed a national sample of undergraduate students in…

This study aims to prepare a scale to determine the creativity levels of prospective teachers studying at the undergraduate level of science teaching. In this context, 15 questions, suitable for student's level from physics, chemistry, biology, astronomy and ecology sub-branches were prepared. The questions were assessed by 5 lecturers who were…

Chirality continues to intrigue scientists because of its implications in various scientific areas, including the long-unsolved question of its development and link with the origin of life. Chirality plays a significant role in medicine with the advent of chiral drugs and the consequent importance of asymmetric synthesis. For many undergraduate…

Background/purpose. Higher-Order Thinking Skills (HOTS) development represents a critical challenge in biology higher education. While Project-Based Learning (PjBL) shows promise, empirical evidence remains fragmented across individual studies. This meta-analysis systematically synthesized evidence on PjBL effectiveness in developing HOTS among…

This paper describes a short ion flow activity that can be completed within one lab or lecture session. The activity is focused on the core concept of flow-down gradients and is geared toward undergraduates. No previous knowledge of equilibrium potentials or membrane potentials is required. Students are guided through a set of questions that build…

Medicinal chemistry is a core course for undergraduate students who major in pharmacy, where complex drug structures and abstruse concepts often pose significant challenges for students. As an important supplement to classroom teaching, online teaching resources have demonstrated the ability to enhance students' interest in learning and improve…

In the environment, communication among microorganisms is a key aspect of their lives. Through communication, single cells of a microbial population can coordinate their gene expression and, in consequence, their physiology. Quorum sensing systems (QS) are one of these mechanisms that allow this communication through the production and detection…

Gender equity is an area of concern within STEM, where women are underrepresented in education and career roles. Increasing the representation of women in STEM and removing negative gender stereotypes are necessary actions, both of which can be fostered during formal education through employability initiatives and in the workplace. This study…
