Microfluidic-based ultramicroscale chemistry experiments involve the manipulation and consumption of reagents on a microliter or submicroliter scale in a microfluidic device. This article presents the pedagogical functions of microfluidic systems, including green chemistry education, stimulation of students' interest in learning about chemistry,…

Students often perceive school science as purely theoretical, overloaded with facts, and mostly disconnected from their school, home, and community life. One way to bridge the disconnection between school science and lived experiences, and support students in realizing the relevance of science to their everyday life, is by enabling them to…

Nowadays there is a concern to improve the quality of education by including an interdisciplinary approach of concepts and their integration in the curriculum of scientific disciplines. The development of microbial fuel cells as a potential alternative for production of renewable energies gives undergraduate students the challenge of integrating…

Many aspects of electrochemical education, such as electroanalysis demonstrations, require three-electrode-cell experimental setups. Many researchers and educators use screen-printed electrochemical electrodes, which are miniature and disposable but are relatively expensive and use proprietary fabrication components. The present article describes…

Liquid metals are widely applied in various fields, including chemistry, catalysis, energy storage, chemical sensing, and stretchable electronics, due to their unique deformabilities. However, their behavior under a rod or ring electrode has never been analyzed. Furthermore, research on the deformation behavior of eutectic Ga--In (EGaIn), the most…

In primary organic chemistry, students learn about the dehydration of ethanol to ethylene with concentrated sulfuric acid. Similar reactions(the dehydration of alcohols) exist in nature. For example, various alkenes with aromas are synthesized from linalool, a monoterpene tertiary alcohol. In this laboratory experiment, we report experiments…

The laboratory plays a crucial role in science education. However, teacher education for pre-service teachers' design performance in the laboratory is still challenging. This study paved the way for redesigning traditional laboratory teaching into a student-centered approach: inquiry-based design thinking (IBDT). To investigate the impact of the…

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…

Education reform calls for portraying science as a process of inquiry and argumentation grounded in the epistemic traditions of a domain. While experimentation is a core scientific investigation strategy, diverse approaches are represented across different domains of science. Ecosystem scientists use experiments as a core part of their…

This study investigates the ability of future primary school teachers to design experiments when confronted with everyday life problems, particularly those involving complex phenomena or counterintuitive outcomes. Data were collected using a content analysis approach from the written assignments submitted during a Science Education university…

A comprehensive teaching experiment plan tailored forthird-yearundergraduates has been developed. Initially, instructors synthesize(E)-2-(4-((4-(2-hydroxyethoxy)-3-methylphenyl)­diazenyl)­phenoxy)-ethan-1-ol­(M-Azo-2)monomer as part of the preclass preparation. Subsequently, studentsperform an acylation reaction experiment to prepare an…

Although the present university-level chemistry experimental curriculum has been extensive and well-designed, it lacks a connection with the scientific research field, especially the frontier field. It is crucial to incorporate recent discoveries through new experiment designs to bridge this gap and boost the value of the undergraduate…

Technological development, particularly in experimental, is now embedded in physics textbooks. Therefore, this study analyzed how the basic inquiry and the integrated science process skills in digital-related experiments are distributed within physics textbooks of South Korea, the United Kingdom, and Indonesia. A descriptive qualitative content…

A discovery-based experiment for the synthesis of arylpropiolic acids via carboxylation of arylacetylenic Grignard reagents was developed. This experiment shows the "dual utility" of Grignard reagents. In the synthesis of arylpropiolic acids reported here, we have demonstrated the use of a Grignard reagent as a base in a "Grignard…

This study reports on the theoretical- and empirical-based design and evaluation of cell membrane biology learning activities within the Model of Educational Reconstruction and experiential realism. First, we designed analogy-based learning activities by considering students' and scientists' conceptions as described in the literature. Secondly, we…
