Over a decade has passed since faculty members' goals for the undergraduate chemistry instructional laboratory were first investigated on a large, national scale in the United States. This study revisits these goals, using data from a 2022 national survey of chemistry faculty members in the United States (n = 521) to investigate current…

The association between student motivation and learning, and changes in motivation across a course, were evaluated for students enrolled in one-semester foundation-level inorganic chemistry courses at multiple postsecondary institutions across the United States. The Academic Motivation Scale for Chemistry (AMS-Chemistry) and the Foundations of…

This research probed the perceptions of secondary school science teachers concerning the objective and utility of assessment, exploring the influences of gender, teaching experience, and specific science subject components. A total of 100 secondary school teachers from Selangor participated in the study, completing the Teacher's Conception of…

The impact of self-regulated learning (SRL) on students' performance in various subjects has been extensively studied. However, there has been limited research on how task-specific SRL skills and self-reported SRL skills affect students' learning outcomes in chemistry classes at senior secondary schools. To address this gap, we examined the…

Low student engagement and motivation in online classes are well-known issues many universities face, especially with distance education during the COVID-19 pandemic. The online environment makes it even harder for teachers to connect with their students through traditional verbal and nonverbal behaviours, further decreasing engagement. Yet,…

Online metacognitive skills are the real-time awareness of cognition, which can effectively promote science learning and improve performance in solving scientific problems. Therefore, it is important to enhance and diagnose students' online metacognitive skills in science education. This study aimed to evaluate ninth-grade students' online…

The study presents an integrated STEM activity involving a 3D printer and entrepreneurial problem solving. The study was conducted with 20 high school students who worked in groups to make their own unique kolonya (a traditional Turkish sanitizer), similar to eau de Cologne. They then designed kolonya bottles using TinkerCad before producing them…

The focus of the present study is the learning processes of concepts related to hydrogen bonds, which were developed using a didactic sequence (DS). Based on the perspective of Imre Lakatos, it was observed whether the explanatory models created by upper-secondary students form progressive transition sequences, which are similar to what Lakatos,…

This study determined how chemistry instruction using technology affected student achievement and retention. To achieve the goal of the study, Solomon's four-group quasi-experimental research design was used. The one-way analysis of variance (ANOVA) and independent sample t-test were used to statistically examine the data. A one-way ANOVA analysis…

Retrieval practice has generally been shown to be an effective study strategy. The benefits of retrieval practice, however, have largely been compared to restudying, a passive and ineffective study strategy. Here, I investigated the memory and metamemory effects of practicing retrieval versus generating mnemonics, an active and effective study…

Secondary school students' early choices related to staying in the science track define their future decisions to choose chemistry at college. This investigation aims at analyzing the role of gender in students' causal attributions to choose or abandon chemistry when it first becomes optional in the Spanish educational system. Our analyses…

Recent progress in elucidating chemical reactions allows to explain chemistry by the potential energy of the involved chemical structures. Nevertheless, from an educational point of view, empirical results indicate that students often do not connect the core idea of energy with other chemical concepts. From a resource-oriented perspective,…

The use of red cabbage ("Brassica oleracea var. capitata F. rubra") extract as a pH indicator is a versatile and popular demonstration that is employed by educators in many schools and universities. Previous variations of this demonstration have used red cabbage extracts to prepare paper that changes color when solutions of acid or base…

In recent years, solar-powered photocatalytic water splitting for hydrogen production has drawn great attention as a method to supply clean energy and reduce environmental pollution. This approach, driven by solar energy to synthesize hydrogen gas, is completely renewable and can be used to power hydrogen fuel cells to effectively solve the global…

The basics of organic chemistry nomenclature were introduced in a laboratory organized in a nonformal environment such as a science festival. The laboratory, divided into three distinct but interconnected activities, was aimed not only at secondary school students but also at lay people. The intent was to explain the importance of associating a…
