Computational thinking (CT) is gaining attention in education as a part of digital literacy and can be addressed in several disciplines, including mathematics. Through the lens of Brennan and Resnick's framework, we investigated how computational concepts, practices, and perspectives can be addressed in upper-secondary statistics lessons using…

An important topic of study in secondary mathematics is non-linear functions, including quadratic equations. In this study, findings from 25 Year 11 students indicated that difficulties with critical prerequisite concepts such as algebraic conventions impeded students' success in understanding and working with quadratics. Analysis of student…

In this article, we explored Grade 11 learners' algebraic and geometric connections when solving Euclidean geometry riders. A qualitative interpretive case study design was followed. Thirty Grade 11 learners from a non-fee-paying secondary school in the Capricorn North district of South Africa were conveniently sampled to participate in this…

This dissertation examines the development of combinatorial reasoning in high school students through an in-depth analysis of a problem-solving session involving the Pizza Problem. The study, part of the long-term Rutgers-Kenilworth longitudinal research project, focuses on four 11th-grade students as they explore and connect concepts related to…

This study, titled "The Effect of Computer Simulation on Grade 11 Learners' Conceptualisation of Stoichiometric Chemistry," was carried out at a school in the Frances Baard District of the Northern Cape province of South Africa. Poor conceptualisation of stoichiometric chemistry by learners in Grades 10-12 in South Africa and, hence,…

This mixed methods study explored how the making of animated models affected year 11 students' understanding of the effect of temperature on the equilibrium of an exothermic or endothermic reaction. The students' perspectives and the role of the activity in facilitating a metacognitive process were also examined. Teacher perspectives were also…

Cosmology concepts encompass complex spatial and temporal relations that are counterintuitive. Cosmology findings, because of their intrinsic interest, are often reported in the public domain with enthusiasm, and students come to cosmology with a range of conceptions some aligned and some at variance with the current science. This makes cosmology…

This study aimed to examine the influence of a culturally adapted and context-specific technique of instruction called the culturo-techno-contextual approach (CTCA) on lowering student anxiety and fostering meaningful learning in difficult biology concepts. A quasi-experimental pre-test and post-test non-equivalent group design was used for this…

The relation between learners' metacognitive skills and conceptual understanding is often portrayed as an input-output relation when dealing with science, technology, engineering, and mathematics (STEM) and non-STEM disciplines. However, studies indicate that not all pedagogies yield positive correlations between learners' metacognitive skills and…

This study aims to determine the feasibility of Instagram-based chemistry learning media and the results of increasing student interest in learning acid-base material in everyday life with a multi-representation approach. The method used in this study is the ADDIE research and development model (Analysis, Design, Development, Implementation, and…

The current study examined self-organized learning environments (SOLEs) pedagogy as a conduit to learners' metacognitive skills and conceptual understanding in physical sciences and science, technology, engineering, and mathematics (STEM) as a whole in Capricorn District of Limpopo Province of South Africa. The aim was based on ongoing debates…

This study aims to determine the effect of the Argument-Driven Inquiry (ADI) learning model on students' argumentation skills and mastery of concepts in human excretory system material, especially in the sub-material of kidney disorders. The research method used quasi-experimental with a group pretest-posttest design. The sample of this research…

The greenhouse effect is a complex scientific phenomenon that plays a crucial role in understanding climate change. Grasping students' understanding of this phenomenon on the content-specific level but also how students' conceptions are organized is vital for effective climate change education. This study addresses both levels and delves into the…

The study examined the impact of concept-based instruction on the teaching and learning of mathematics. Functions is the topic that was implemented in order to identify the improvements in learners' understanding. A total of 35 Grade 11 learners from a South African township school in Limpopo province participated in this study. Data were…

In the present study, text presentation in biology textbooks was analyzed with respect to misconception and elements of conceptual change towards the learning of "Cell Structure". Content analysis of the lesson "Cell Structure" in five biology textbooks of Grades 11 and 12 across selected educational boards in Asia like the…
