Acid-base physiology is widely recognized as one of the most conceptually challenging topics in undergraduate education due to its interdisciplinary nature and the necessity for both mechanistic and integrative understanding. This article presents a structured, system-based teaching framework designed to enhance student comprehension of acid-base…

Chemistry education researchers have, for many years, explored different ways of learning chemistry through modeling and open-ended problem-solving. With the emergence of generative artificial intelligence (GenAI) tools such as ChatGPT, students now have access to dynamic scaffolds that can potentially support them in modeling. However, we still…

Valid rubrics facilitate assessing the level of complexity in students' open-ended responses. To design a valid rubric, it is essential to thoroughly define the types of responses that represent evidence of varying complexity levels. Formulating such evidence statements can be approached deductively by adopting predefined criteria from the…

Background/purpose: Chemistry is one of the five science subfields typically covered in secondary schools in the United Arab Emirates. Chemistry is a branch of science that studies the properties, composition, and structure of substances. Numerous subfields fall under the umbrella of chemistry, including inorganic, organic, analytical, and…

Chemistry labs are often taught using a rote mechanical approach without much explicit scaffolding for academic reflection by the students. Reflection, however, can play an essential role in learning because it is an evidence-based learning process that generates, deepens, critiques, and documents learning. By moving away from traditional teaching…

The idea of a practical examination in a subject is an old and established one in many fields, within chemistry, in widely differing areas of academics, and in many on-the-job training scenarios. In a dedicated course on chemical safety, we have found that "the unsafe lab practical" makes for a thought-provoking and yet fun final…

Although the phrase "seat of EMF" in describing chemical cells has fallen into disuse, by distinguishing the distinct but incorrect conceptions both of Galvani and of Volta, in favor of the correct view of Faraday, "seat of EMF" it becomes possible (among other things) to understand: (1) why internal resistance really is…

Syntheses of analogues of historical indigo and Maya blue pigments using an inquiry-based approach are presented. Derivatives of indigo were synthesized (in particular Tyrian purple) and used as vat dyes for dyeing cotton or wool fabrics or mixed with a sepiolite clay to create new hues or colors of Maya blues using a green chemistry hydrothermal…

Aqueous dispersions of soot and other carbon materials, prepared in a manner similar to that used for preparing traditional Japanese ink, were developed as teaching materials for colloid chemistry. The protective colloid formed by the addition of glue is an interesting teaching material that allows visual understanding of various colloidal…

Inert gas manifolds for the handling of air-sensitive materials are commonplace in the inorganic chemistry curriculum as well as in research laboratories specializing in inorganic and organometallic synthesis. Mercury bubblers are ubiquitously implemented for maintaining a positive internal pressure for air-free manifold systems, commonly known as…

The SIR model is a differential equations based model of the spread of an infectious disease that compartmentalises individuals in a population into one of three states: those who are susceptible to a disease (S), those who are infected and can transmit the disease to others (I), and those who have recovered from the disease and are now immune…

This paper aimed to examine the changes in the representations of nature of science (NOS) in Chinese senior high school chemistry textbooks under the influence of the new curriculum ideas. The study was conducted based on an analytical framework in which the aspects of NOS, the approaches to address NOS, and the content relation of NOS aspects…

This study focuses on examining senior high-school students' conceptual understanding and difficulties concerning electrochemistry and comparing patterns of thinking across Turkish and Indonesian contexts. The Electrochemistry Concept Questionnaire (ECQ) was applied to 516 Indonesian and 516 Turkish high school students right after the teaching of…

Teaching is a complex activity that demands paying attention to diverse components and relationships that affect the learning process, and acting with intentionality to build and nurture those connections. In this qualitative research study, we proposed and used an intentional-relational framework to explore differences in the relationships that…

Navigating the observational, symbolic, and theoretical knowledge domains of chemistry is crucial for chemistry sensemaking. However, this has been shown to be particularly challenging for students of chemistry. In order to reach government standards for sensemaking in the chemistry subject, it is important to investigate how chemistry teachers…
