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…

The study investigated the effects of the use of dynamic computer visualizations (DCVs) integrated with the POE (Predict-Observe-Explain) sequence on learners' understanding and retention of solubility and on their motivation to learn chemistry. In the research, nonequivalent groups pretest--posttest control and comparison group design was used.…

Secondary students' perceptions of learning science and mathematics have been researched internationally, but less in the global South. This study investigated Grades 9 and 10 students' experiences of learning biology, chemistry, physics and mathematics in Bhutanese secondary schools. A mixed-methods sequential design was used. First, 524 students…

A solid grasp of basic concepts and their relationships can stimulate learning motivation, improve teaching quality, and help students to build a body of knowledge in a discipline. Most of the previous studies have considered one chemistry topic amongst many others. To date, no studies have been conducted to explore the conceptual structures of…

Organic Chemistry I presents challenges to many students pursuing diverse fields of study, oftentimes curtailing further progress in those fields. The ability to identify students at risk of unsuccessful course outcomes may lead to improved success rates by offering tailored resources to those students. Previously identified predictors include…

While uncertainty is inherent to doing science, it is often excluded from science instruction, especially postsecondary chemistry instruction. There are a variety of barriers to infusing uncertainty into the postsecondary chemistry classroom, including ensuring "productive" struggle with uncertainty, evaluating student engagement with…

Explicit teaching of metacognition, 'thinking about one's thinking,' has been shown to improve achievement scores in the general chemistry tests and facilitate the awareness and adoption of metacognitive strategies. However, very few studies have investigated variations in the reported metacognitive strategies employed by college science majors by…

Nuclear magnetic resonance (NMR) spectroscopy is a very powerful analytical method that has found many applications in physics, chemistry, biology, and medicine. It is an indispensable tool particularly for synthetic chemists because it can be used for a rapid elucidation of the structures of organic compounds. For this reason, NMR spectral…

Plant-derived natural products are an important source of potential medicines and continue to have a major impact on the drug discovery process. Natural product discovery assignments provide an opportunity to present various experimental techniques to undergraduate students in introductory medicinal chemistry. This assignment was developed to…
