Purpose: This research aims to examine the pre-service teachers' learning when using STEM tasks with middle school students in a lesson study. Design/methodology/approach: This research adopted a qualitative methodology with an interpretative orientation. The participants are three pre-service teachers involved in a lesson study that took place in…

In the field of education, the integration of technology has grown, providing new opportunities for teaching and learning. One emerging technology that has gained attention is Artificial Intelligence (AI). This study investigates Lebanese chemistry teachers' knowledge and perceptions of AI, examining the benefits and challenges they anticipate or…

The ability to elucidate the structure of organic compounds from their nuclear magnetic resonance (NMR), infrared (IR), and mass spectrometry (MS) spectra is an essential skill, particularly for those engaged in the fields of synthetic and analytical organic chemistry. Spectral analysis constitutes a fundamental component of the curriculum for all…

To prepare students to use science knowledge in their later personal or professional lives, we must attend to what they believe it means to know and learn science (i.e., epistemology). Unfortunately, we have little understanding of how students' epistemologies shift and are stabilized as they navigate their science courses. Researchers have made…

Cognitive load studies are mostly centered on information on perceived cognitive load. Single-item subjective rating scales are the dominant measurement practice to investigate overall cognitive load. Usually, either invested mental effort or perceived task difficulty is used as an overall cognitive load measure. However, the extent to which the…

This study examines prevalent misconceptions among students regarding the fundamental concepts of acids and bases, which often arise during the learning process. This study aims to pinpoint misconceptions held by preservice science teachers in the realm of acids and bases; 117 university students from diverse educational backgrounds, enrolled in…

In the context of scholarly and scientific discourse, students often have to deal with graphic-visual modes of communication, which requires their ability to comprehend and utilize inscriptions, that is, scientific visual representations, to convey information effectively--what we call graphical literacy. Despite its pivotal role for training…

Climate change is one of the socio-environmental problems with the greatest complexity and media impact in the world. However, difficulties have been observed in its understanding. In this study, we worked on this social problem in the classroom through argumentation, from the evaluation of different statements made about the causes and…

Chemistry is a natural science that explores the composition, structure, and transformations of matter. Technological innovations have transformed both teaching methods and learning processes. To explore the transformative potential of virtual technologies in chemistry education, this study conducted a meta-analysis to assess their impact on…

NMR prediction using ChemDoodle, NMR calculation with Gaussian, and hands-on data collection using a benchtop NMR spectrometer were explored to assess their synergistic capacity in teaching NMR to organic chemistry students. Nine molecules representing functional groups commonly encountered in undergraduate organic chemistry were selected. Spectra…

Atomic-level visualizations serve as pivotal instructional tools in chemistry education, providing insights into the particulate level of matter, a dimension fundamental, yet typically invisible, in the study of chemistry. This research investigates how students' engagement with these visualizations influences their conceptual understanding of…

To address the changes that exist in the educational field, educators and curriculum developers are in constant search for innovations to keep up and foster alongside this timely educational revolution. In this case, this study emphasized the integration and parallel use of Phenomenon and Project based learning methods in High School General…

This article describes the design, implementation, and evaluation of the gamification of laboratory activities in a General Chemistry course at the Federal University of Ceará in Brazil. In the gamified laboratory, seven experiments traditionally performed in the course were transformed into ten missions, incorporating game elements such as…

Background: Much of the research into the use of drama in science education has been qualitative, with its primary focus being on its "affective" value amongst students aged 6-14 years, with a smaller fraction on effectiveness in terms of academic achievement and understanding of chemistry amongst older school students (16-18 years).…

This study reports an undergraduate laboratory experiment that explores the temperature-dependent kinetics of caffeine release during tea steeping by using quantitative [superscript 1]H NMR spectroscopy with a water suppression pulse sequence. Designed for introductory organic chemistry laboratory courses, the experiment emphasizes the real-world…
