The purpose of this study is to "meta"-analytically evaluate research that used chemical bonding-based interventions to improve academic performance. Through "meta"-analysis, the present study used several keyword patterns (e.g., chemical bonding, experimental, chemistry education, science education) via relevant databases…

Background: Prior research suggests that the teaching of abstract concepts can be enhanced by the use of concrete examples, but there are few controlled studies. Objective: To replicate key findings from experiment one from Rawson et al. (2015). Method: Experiment participants studied definitions of abstract concepts from psychology, either with…

Today, immersive technologies like Virtual Reality (VR) are regarded as disruptive tools in many domains, including education. While the body of literature in the field is growing, studies that present contrasting findings are not uncommon. In fact, although there is evidence of the benefits brought by VR in the educational processes, in some…

A multicomponent reaction was adapted and successfully applied in the major organic course, which involves synthesizing and characterizing a 1,3-benzoxazine derived from paracetamol extracted from tablets of the worldwide well-known medicine Tylenol. Using paracetamol as a reagent is a motivational strategy in undergraduate laboratories to meet…

This article aims to simplify and facilitate the process of practical teaching of enzyme kinetics by utilizing minimal teaching laboratory requirements. Simultaneously, it ensures that students comprehend the enzyme kinetics experiment effectively. The focus is on teaching students how to estimate the maximum velocity (Vmax) and Michaelis constant…

As a rule, an experiment carried out at school or in undergraduate study courses is rather simple and not very informative. However, when the experiments are to be performed using modern methods, they are often abstract and difficult to understand. Here, we describe a quick and simple experiment, namely the enzymatic characterization of ptyalin…

Given the severe pollution caused by traditional plastics, biodegradable plastic products (BPPs) have received great attention and are appearing in people's lives in the form of packaging bags, tableware, etc. Whether a wide variety of BPPs can truly degrade depends on the environment. Aerobic composting is the arbitration method to evaluate the…

In recent years, the theoretical lens of new materialism(s) and surge in feminist thinking has opened up new ways of understanding the complexities of motherhood, babyhood and early childhood. This surge in post-qualitative and feminist inquiry towards the troubling of dominant early childhood abstractions and norms, as well as resistance to…

Background: Clustered randomized controlled trials are commonly used to evaluate the effectiveness of treatments. Frequently, stratified or paired designs are adopted in practice. Fogarty (2018) studied variance estimators for stratified and not clustered experiments and Schochet et. al. (2022) studied that for stratified, clustered RCTs with…

Electrophilic aromatic substitution (S[subscript E]Ar) and nucleophilic aromatic substitution (S[subscript N]Ar) reactions are among the most valuable reactions in the conversion of aromatic rings. While these reactions are typically covered in separate experiments in undergraduate organic courses, a continuous experimental setup elucidating both…

A comprehensive chemistry laboratory experiment, including the synthesis of Pt/Al[subscript 2]O[subscript 3] catalysts at different conditions, structure characterization, and the real-world application exploration, has been designed for upper-division undergraduate and graduate students as an expansion and improvement of the professional…

A laboratory experiment that involves the aqueous and solid phase synthesis, characterization, and solvatochromic properties exploration of red complex [Ni(Me[subscript 3]en)(acac)]BPh[subscript 4] has been developed for first-year undergraduates in the College of Chemistry and Chemical Engineering at Xiamen University. In contrast to previously…

Four General Chemistry instructors investigated the use of ChatGPT-4 to improve their lessons plans for the historical experiments of Thomson, Millikan, and Rutherford. The instructors varied in their prior knowledge for these experiments and their initial lessons addressed somewhat different learning objectives. This led to different…

To improve the experimental interest and innovative ability of advanced undergraduate students, a luminescent sensing laboratory experiment with visual performance characteristics is introduced. Students have synthesized an organic hybrid cage-like europium-germanate oxo cluster with the formula of [Eu[subscript 8](phen) [subscript 2]Ge[subscript…

Despite the growing awareness of the importance of plant secondary metabolites in insect-plant interactions, undergraduate degree content in agronomy and biology generally does not provide a clear concept to students in relation to secondary metabolite induction of plant defences, implying that students do not obtain a good understanding of the…
