Measuring Students' Learning and Attitude as Exposed to Microscale Laboratory Experiments in Inorganic Chemistry

Abstract

Microscale chemistry is an approach to conducting chemistry experiments which can help overcome increased concerns about environmental pollution problems as well as rising laboratory costs. It is accomplished by using miniature labware and significantly reduced amounts of chemicals. The main goal of this study was to explore whether the use of microscale chemistry experiments can increase student’s understanding of chemistry concepts and improve attitude towards chemistry practical work. Quasi-experimental design without control group was used to determine from purposively selected class of 40 freshman students of Bachelor of Secondary Education (BSE). The students worked in groups on eight microscale chemistry experiments in a period of 8 weeks. Pre and post-test were administered before and after the treatment. Results revealed that microscale approach significantly improved student chemistry academic performance. Students’ perception of microscale is positive. Findings showed that the microscale approach can increase understanding of chemistry concepts.

On-the-Go Lab for Aqueous Reactions Demonstrations: Activities at the Microscale

“…Numerous studies have highlighted the effectiveness of microscale experiments and demonstrations in supporting chemistry courses in high schools and colleges. − Microscale experiments not only enhance students’ understanding of classroom concepts but also reduce the amount of required reactants, aligning with green chemistry principles. It has been widely acknowledged that these activities contribute to sustainable and eco-friendly lab practices. − Green chemistry principles outlined by the American Chemical Society aim to reduce waste, conserve energy, and find substitutes for hazardous substances, safeguarding the economy, people, and the environment . Microscale activities are a great way to reduce waste and are just as effective as regular scale experiments.…”
