This paper discusses the relevance of using physical situations to introduce the concept of angles at elementary school. We compare the effectiveness of two geometry teaching sequences. In the first one (physical sequence), the pupils learned the angle concept by experimenting on the playground (i.e. mesospace) and then modelling the situation. In…

This article presents the "modus operandi" of a game, the so-called Game of Shapes, which can be used as an active learning tool to teach Constructivism to introductory International Relations courses. While sharing our own experience of the development and application of the game in a laboratory with International Relations students,…

The 21st-century mathematics classrooms should equip learners with well-grounded knowledge and thinking skills pertaining to geometry. However, Euclidean geometry remains one of the challenging, if not the most difficult topic for many learners. As a result, the purpose of this article is to interpret Grade 12 learners' learning difficulties in…

The Compulsory Education Course Standards for Mathematics 2022 have highlighted the educational objectives of junior secondary mathematics by emphasizing the development of mathematical competence and practical learning. Model consciousness, as one of the fundamental mathematical competencies to be developed at the junior secondary level, can…

This work presents the result of the application of a didactic sequence designed to understand the concept of the Cavalieri's Principle, supported by the GeoGebra application in its version for mobile phones -- 3D Calculator. For this study, the Theory of Categories of Intuitive Reasoning, by Efraim Fischbein, was used as a conceptual basis. The…

One innovation that can be developed based on the problem learning angle created is the movement of line marching skills as learning media alternatives for students. This study aims to determine the effectiveness of using the Gebar Modules. The sample comprised 30 students from grades 4A and 4B who were randomly selected with one-group…

Children on the autism spectrum often have deficits in language development. Given the resources required to provide intensive intervention services, either in person or via telehealth, it may be important to maximize instructional time by using procedures that lead to generative language use, such as matrix training. Matrix training involves…

The purpose of this study is to examine the effect of a technology-enhanced collaborative learning environment on secondary school students' mathematical reasoning in the concept of triangle. The participants of the study are 30 secondary school students. This study was carried out with the embedded design, one of the mixed methods designs. The…

Learn how to engage students in geometry concepts through a real-world task that leverages GeoGebra to provide students with generalization and authorship opportunities. This article shares the story of a geometry task that asked students to choose a city that would best work for their new trucking company. Throughout the task, students noticed…

Recent research on multimedia learning has considered the integration of cognitive and affective aspects of media processing. The literature suggests that learners' emotions influence the effectiveness of multimedia learning, which is explained by the cognitive-affective theory of learning with media (CATLM). A multimedia design that changes…

Aim/Purpose: This paper addresses the effectiveness of flipped learning and teaching as a didactic innovation in math instruction. We are interested in comparing traditional and flipped learning and teaching in terms of acquired knowledge and retention and students' perceptions of flipped learning and teaching. Background: Traditional lessons, in…

The global pandemic has changed the mode of delivering lessons. Adult learners have missed and continue to miss the hands-on learning activity, which is a form of experiential learning. When it comes to teaching three-dimensional, geometric shapes (3D), learners often benefit from handling and manipulating concrete shapes. This study examined the…

Although basing instruction on learning trajectories (LTs) is often recommended, there is little direct evidence regarding the premise of a LT approach--that instruction should be presented (only) one LT level beyond a child's present level. We evaluated this hypothesis in the domain of early shape composition. One group of preschoolers, who were…

The present study examined the effects of the non-digital game-based instructional method and the cognitive level of questions in determining students' achievement in mathematics, particularly in Isometric Transformation. The study used a quasi-experimental design and involved 116 participants (i.e., form two students) from two local secondary…
