Over four decades of conceptual change studies in education have been based on the assumption that learners come to science classrooms with functionally fixated intuitive ideas. However, it is largely ignored that such pre-instructional conceptions are probabilistic, reflecting some aspects of an idiosyncratic sampling of their experiences and…

For decades, two critical challenges have plagued school science in the years it is compulsory for students in many educational contexts across the globe: how best to identify what science is meaningful for all students to learn during their formal school science education, and how to keep these students engaged in the learning of this science.…

The Instrumental Analytical Chemistry course, taught in the fifth semester across several programs at the Faculty of Exact Sciences of the National University of La Plata, places a significant emphasis on high-performance liquid chromatography (HPLC). This versatile analytical technique is essential for the separation, identification, and…

Understanding molecular structure is fundamental in chemistry education. However, commercially available molecular model kits are often expensive and are not always present in educational institutions. Here we present "ChemBotCap," an innovative, low-cost, and engaging alternative for modeling simple inorganic and organic molecules using…

Background/purpose: The study aimed to investigate the effectiveness of teaching based on multiple intelligences in acquiring chemical concepts and the ability to explain household chemical phenomena among basic-stage students. Materials/methods: The study employed an experimental method with a quasi-experimental design for two non-equivalent…

This study aims to develop and validate a Constructivist Learning Environment Model to address secondary students' misconceptions in learning Science. Employing a Design and Development approach (Richey & Klein, 2007), the research is conducted in two phases. Phase 1 focuses on model design, drawing from an extensive literature review to…

In this paper, we describe our extension of the action, process, object, schema (APOS) theory to capture the complex interplay of mathematics and physics. We do this in the context of the 2D heat equation. We describe a hypothetical learning trajectory of the 2D heat equation, a preliminary genetic decomposition that stresses the conceptual…

The societal and industrial relevance of chemistry has established its status as a compulsory subject in numerous national curricula. However, previous research highlights significant challenges faced by students in learning chemistry, largely attributed to its abstract nature and the multiple ways chemical concepts are represented. These…

Understanding the structure and function of proteins is crucial for students as it provides fundamental insights into one of the central building blocks of life. Yet, undergraduate students struggle to make sense of proteins and apply knowledge about why structure affects function. Here, we expand on an existing typology of common protein…

Dealing with students' conceptions is a central element of student-oriented teaching. Approaches, such as the mainly cognitive conceptual change theory, have been supplemented by a variety of affective and motivational factors. Little is yet known about the mechanism linking these factors. This qualitative study aims to shed light on the process…

The importance of introducing students to mechanistic reasoning (MR) early in their schooling is emphasised in research. The goal of this case study was to contribute with knowledge on how early primary students' (9-10 year-olds) MR in chemistry is expressed and developed in a classroom practice framed by model-based inquiry. The study focuses on…

The Brief Electricity and Magnetism Assessment (BEMA) is a multiple-choice instrument commonly used to measure introductory undergraduate students' conceptual understanding of electricity and magnetism. This study used a network analysis technique called modified module analysis-partial (MMA-P) to identify clusters of correlated responses, also…

Genetic variation is historically challenging for undergraduate students to master, potentially due to its grounding in both evolution and genetics. Traditionally, student expertise in genetic variation has been evaluated using Key Concepts. However, Cognitive Construals may add to a more nuanced picture of students' developing expertise. Here, we…

Evaluating evidence and restructuring beliefs based on anomalous evidence are fundamental aspects of scientific reasoning. These skills can be challenging for both children and adults, especially in domains where they possess inaccurate prior beliefs that can interfere with the acquisition of correct scientific information (e.g., heavier objects…

Thermal cameras have shown to have utility in secondary school classrooms and undergraduate courses. In this paper, the author argues for their potential in the primary school classroom and presents a range of activities that can be undertaken with thermal cameras (or supplied images). With limited access in mind, the activities in this paper have…
