A problem-solving experiment is a learning activity that uses experimental design to solve an authentic problem. It combines two evidence-based teaching strategies: problem-based learning and inquiry-based learning. The use of problem-based learning and scientific inquiry as an effective pedagogical tool in the science classroom has been well…

The COVID-19 outbreak represented a remarkable challenge in universities and colleges since it forced the transition from a face-to-face model in classrooms and laboratories to a remote, online model using computers, tablets, and cell phones. In Mexico and other Latin American countries, the return to educational activities was a slow-paced…

A multioutcome, guided inquiry-based liquid--liquid extraction (LLE) experiment has been designed for introductory organic chemistry. Multiple outcomes were established by identifying a series of red and blue dyes that are (1) soluble in organic solvent, (2) soluble in aqueous solution, or (3) soluble in either the organic or aqueous layers by…

As an outcome of multidiscipline integration, the polymeric surfactant is of growing importance in modern industry and scientific research. However, the instructional introduction on polymeric surfactants is still insufficient in universities nowadays. In order to effectively guide undergraduates to study polymeric surfactant, a new polymeric…

Clathrate hydrates are attractive materials for education because they form from water and familiar compounds, such as carbon dioxide, and are relevant to novel technologies. In this study, an attempt to propose a laboratory experiment was summarized, which used carbon dioxide clathrate hydrate as an educational material with carbon capture…

Socially shared metacognition is important for effective collaborative problem solving in virtual laboratory settings, A holistic account of socially shared metacognition in virtual laboratory settings is needed to advance our understanding, but previous studies have only focused on the isolated effect of each dimension on problem solving. This…

Laboratory safety is a vital part of a chemical education and can be incorporated into courses throughout the chemistry curriculum. Discussions of laboratory safety can serve as an introduction to the important field of green chemistry. Exposure to this field can better prepare students for safer and more sustainable laboratory practices in…

In today's global economy, the origin of the food we eat is becoming more and more difficult to identify. Verifying the authenticity of products to protect supply chains is a complicated problem that requires a multidisciplinary approach. Chemical authentication of foodstuffs often includes a mass spectrometer detector; however, they are costly…

This paper describes an inquiry-based integrated laboratory project for green synthesis, characterization, and applications of silver and gold nanoparticles. In this project, students were able to choose their choice of plant extract as reducing and stabilizing agents, and the students also designed their own experiments. This course gave the…

The current study aims to examine the effects of prospective chemistry teachers' chemistry laboratory teaching experiences using different laboratory approaches on their metacognitive thinking skills and perceptions of problem-solving skills. The study is designed as "'the quasi-experimental non-equivalent pre-test/post-test control group…

This work presents experiments to teach fundamentals of automation through a sequence of laboratory practices that naturally guide to development of an on/off control system. It focuses on the integration of technological and scientific concepts, based on an educational approach associated with a problem-solving technique.

Reform documents advocate for innovative pedagogical strategies to enhance student learning. A key innovation is the integration of science and engineering practices through engineering design (ED)-based physics laboratory tasks, where students tackle engineering design problems by applying physics principles. While this approach has its benefits,…

Novice chemists often struggle with the highly visual nature of some chemistry topics. To make visually demanding concepts, such as isomerism and stereochemistry, more accessible to students, chemistry instructors have long recommended the use of molecular model kits as visual aids. However, studies pertaining to student model usage have shown…

To improve the quality of education, it is important for teachers to have an understanding of action research. Action research is 'learning by doing', which involves identifying a problem, looking for a plan to resolve it, observing how successful it is and, if not satisfied, trying again. Action research helps educators to be more effective in…

The COVID-19 epidemic adversely impacted chemical engineering experiments(CEEs). Students underwent online learning, i.e., software simulation of the CEE course, instead of laboratory learning. A questionnaire survey revealed that students exhibited low enthusiasm for online learning, showing that online courses cannot ensure learning quality.…
