The alignment of teaching and assessment in chemistry courses is critical for the practice of science and positive student learning outcomes. This paper addresses how instructors can align what they do in class with assessments across topics to improve students' understanding and explanations of chemical phenomena. We drew on the foundations of…

One of the critical goals of teaching chemistry is to enable learners to gain conceptual understanding. Traditional instruction has often been associated with rote memorisation, resulting in learners failing to explain observed chemical phenomena, make predictions based on acquired concepts, advance convincing arguments, and engage in meaningful…

Background: The views of the nature of science (VNOS) is one of the important goals of science education. According to information processing constructivism, learners' psychological factors that may influence VNOS include scientific argumentation (SA), metacognition (MC) and epistemic beliefs (EB). Purpose: This mixed-methods study aims to analyse…

Chemical thinking has been widely recognized as a core competence for supporting students' problem solving in chemistry education. Disciplinary essential questions and perspectives are two critical aspects of chemical thinking. This study connects essential questions with such perspectives to develop a new framework for restructuring chemical…

This systematic review aims to provide evidence-based literature on the impacts of technology-based instruction on students' academic achievements, attitude, and recalling capacity. The review was made based on the Preferred Reporting Items for Systematic and Meta-Analysis (PRISMA) review methodology. To achieve this aim, 583 prior studies from…

This article describes a novel method for quantifying fixation disparity and evaluates its role in visuospatial cognition during an authentic learning task, specifically, the determination of molecule chirality in organic chemistry involving mental rotation and pattern comparison. The first study examined the influence of molecular model…

Redox reaction is a core chemical concept. However, its abstract nature makes it very difficult for students. Students' conceptual structure reflects their mastery of concepts, which helps teachers implement targeted educational strategies. This study aimed to explore the conceptual structures of redox reaction held by students (grades 10 to 12)…

This exploratory study uses a mixed-method approach to examine students' perceptions of inclusion in a large first-semester General Chemistry course that occurred during COVID-19. In a survey given at the end of the semester, we asked students to rate their course inclusion and to provide an open-text explanation of their score. Qualitative…

Understanding the general ideas and methods of detecting molecular structures is essential in high school chemistry. However, there is a need for more practical activities in teaching. A hands-on activity was designed in this study, which uses flexible foam balls and long sticks such as knitting needles to imitate how scientists construct the 3D…

This study examines the impact of hands-on chemistry laboratories in shaping secondary students' chemistry self-concepts. Utilizing a mixed methods approach, the research sought to address how students' chemistry self-concept varied during the first semester of an introductory chemistry course and give voice to students' understanding of the role…

The chemical experiment in this study is specifically created for undergraduate students studying energy and the environment. The target of the experiment is for students to comprehend the deactivation mechanism of the Ce/TiO[subscript 2] catalyst by oxides of phosphorus through practical experiments and enhance their knowledge of environmental…

The lateral flow immunoassay (LFIA) is a simple and cost-effective rapid diagnostic test designed for the on-site detection of disease biomarkers. In the context of introducing this technique to undergraduate biotechnology students, we propose a comprehensive 5 h laboratory experiment. This experiment covers various aspects, including the…

In order to improve the accessibility and user friendliness of an accurately pretrained stacking ensemble machine learning regressor used to predict sulfate levels (mg/L) in Acid Mine Drainage (AMD), a Graphical User Interface (GUI) was developed using Python by combining human input with ChatGPT and deployed in the Jupyter Notebook environment.…

The utilization of virtual compound libraries and virtual screening has become a routine method in drug discovery and has accelerated the research of pharmacy and translational medicine. With the development of computer-aided drug design (CADD), it is essential to incorporate virtual experiments into the education of medicinal chemistry. Herein,…

We describe a three-day advanced organic laboratory experience that includes the solid-phase synthesis of an unknown three amino acid polypeptide for junior/senior undergraduate chemistry majors. Students conduct a series of 1D and 2D NMR experiments (HSQC, HMBC, TOCSY) and analyze the data to identify the side chain residues of the peptide and…
