Sustainability transitions need professionals with specific skills and attitudes that students often do not develop in their regular chemistry education. To foster sustainability change-maker competencies, we suggest augmenting higher education curricula, e.g., chemical degree programs, with transdisciplinary challenge-based learning combined with…

Spaced practice is a recognized effective study approach that fosters mastery of learning and retention of information. In this paper, we share one instructor's experience in introducing a spaced practice intervention in a large general chemistry course and in encouraging students to continue the strategy in the next semester organic chemistry…

Social cognitive career theory posits that career interests and decisions are influenced by individual, contextual, and behavioural factors. This research aims to assess the impact of Science, Technology, Engineering, and Mathematics (STEM) activities on students' interest and aspirations in STEM careers. Additionally, the study aims to explore…

The retention disparities in undergraduate degree attainment are a persistent problem within the United States, especially for Black, Indigenous, People of Color (BIPOC), first-generation and low-income students, and women (referred to as marginalized groups in STEM [MGS] hereafter) pursuing STEM degrees. The following exploratory article…

This case study examined the transdisciplinarity and complementarity of a double degree program in undergraduate chemistry and computer engineering, based on the perspectives of its graduates. Semi-structured interviews were conducted with eighteen graduates to explore how well the program integrated both disciplines and prepared them for the job…

Despite standardized engineering and administrative controls, accidents persist in chemistry laboratories owing to the inherent complexity of the experiments. As a result, there is an increasing need to strengthen safety culture, which is built on a safety mindset and refers to an institution's knowledge, attitude, and practice (KAP) of laboratory…

Detailed learning objectives foster an effective and equitable learning environment by clarifying what instructors expect students to learn, rather than requiring students to use prior knowledge to infer these expectations. When questions are labeled with relevant learning goals, students understand which skills are tested by those questions.…

This study investigated students' meaning-making of polymeric concepts during modelling and discuss students' creation of visible representations in chemistry. The analysis combines a phenomenographic and social semiotic approach and leads to the finding and description of 21 different meaning-making processes. We refer to meaning-making as the…

The microscopic composition of substances is a piece of essential but abstract knowledge in chemistry. Junior high school students may experience difficulty in mental representation when learning micro concepts, which leads to problems such as unsatisfactory academic performance and low learning motivation. Augmented reality (AR) is an optimal…

This research aims to develop chemistry project-based learning with an Integrated Ethnoscience Approach in Science, Technology, Engineering, and Mathematics (Ethno-STEM) to improve students' conservation and entrepreneurial character. The research method refers to the Research and Development (R&D) model with the Four D. The research samples…

In the virtual laboratory learning process, students' scientific abilities in solving a problem are very important to explore. This study aims to develop classroom-based authentic assessment instruments through virtual laboratory learning in chemistry to see an increase in students' scientific performance. The research was conducted at a public…

The aim of this study was to compare the 5E learning model with traditional learning methods in terms of their effect on students' conceptual understanding of water subtopics. The participants of the study were grade 8 students of 2021 academic year. While 27 of them were randomly assigned to the experimental group, the other 27 were assigned to…

This article reports on a study of understanding of key sub-topics of the curricular model of covalent bonding among participants at all levels of the chemical education system in Croatia, including among secondary school students, university students (some of whom are pre-service teachers), and secondary school chemistry teachers. The diagnostic…

For chemistry, where learners are required to integrate experimental observations with theoretical knowledge, laboratory work appears to be a viable instructional strategy. However, research has shown that chemistry laboratory instruction often fails to live up to its potential. The scheduling practice in higher education (HE) separating theory…

Educators play a key role in facilitating interactive learning experiences in informal science education settings, such as science centers and museums. Despite their importance, research around facilitation has generally focused on visitor impacts and not the strategies used by the educators themselves. The "ChemAttitudes" project…
