Lena Frenken; Paul Libbrecht; Benjamin Becker; Gilbert Greefrath – International Journal of Mathematical Education in Science and Technology, 2024
The German national educational standards state explicitly that students should be enabled to successfully interact with dynamic geometry software. In a feasibility study on providing a standardized assessment instrument by digital means, in order to assess students' mathematical competencies, the implementation of a task with such a dynamic…

Ingi Heinesen Højsted; Maria Alessandra Mariotti – International Journal of Mathematical Education in Science and Technology, 2024
This article reports on the design and implementation of a didactic sequence in the frame of a design-based research study. The research aim is to test the hypothesis that affordances of dynamic geometry may support students' awareness of logical relationships between geometrical properties of constructed figures. We elaborate on the task design…

Mehmet Demir; Yilmaz Zengin – International Journal of Mathematical Education in Science and Technology, 2025
The aim of this study is to show how the GeoGebra software-supported collaborative learning environment contributes to a group of students using multiple representations and reaching generalisations while solving problems collectively. Blending individual and collaborative learning activities were carried out with a learning method called ACODESA…

Giovanna Valori; Belén Giacomone; Veronica Albanese; Natividad Adamuz-Povedano – International Journal of Mathematical Education in Science and Technology, 2024
The combined use of origami and dynamic geometry software has recently appeared in mathematics education to enrich students' geometric thinking. The objective of this research is to study the roles played by the interaction of two artifacts, paper folding and GeoGebra, in a construction-proving problem as well as its generalization in the…

Gabour, Manal – International Journal of Mathematical Education in Science and Technology, 2022
In this article special sequences involving the Butterfly theorem are defined. The Butterfly theorem states that if M is the midpoint of a chord PQ of a circle, then following some definite instructions, it is possible to get two other points X and Y on PQ, such that M is also the midpoint of the segment XY. The convergence investigation of those…

Demir, Mehmet; Zengin, Yilmaz; Özcan, Sule; Urhan, Selin; Aksu, Nazli – International Journal of Mathematical Education in Science and Technology, 2023
The purpose of this study is to examine secondary school students' mathematical reasoning about the area of the circle. Mathematical tasks designed using GeoGebra were performed within the context of the 5E-based flipped classroom approach. The participants of the study are 13 secondary school students. The tasks, video and audio recordings…

Cetin, Ibrahim; Dev, Serife – International Journal of Mathematical Education in Science and Technology, 2023
This study investigated the methods that pre-service teachers employed while finding volume using integration and the reasons why they utilized these methods (problems); the accuracy of their solutions was also analyzed in this study. Case study design, a qualitative research method, was used for this study. 45 sophomore pre-service teachers…

Birgin, Osman; Acar, Hatice – International Journal of Mathematical Education in Science and Technology, 2022
The aim of this study is to determine the effect of computer-supported collaborative learning (CSCL) using GeoGebra software on 11th grade students' achievement in exponential and logarithmic functions. This study was carried out with quasi-experimental design consisting of a pre-test and a post-test with the experimental group and the control…

Yeung, Wing-Leung; Ng, Oi-Lam – International Journal of Mathematical Education in Science and Technology, 2022
In this paper, we introduce a technology-enhanced pedagogical sequence for supporting lower secondary school students' sense-making of the concept of volume in a non-procedural and non-formula-driven way. Specifically, we illustrate a novel approach of using dynamic geometric environment (DGE) to introduce the meaning of volume and then deriving…

Nordlander, Maria Cortas – International Journal of Mathematical Education in Science and Technology, 2022
The purpose of this paper is to follow the reasoning of high school students when asked to explain the standard trigonometric limit lim/[theta][right arrow] sin[theta]/[theta]. An observational study was conducted in four different phases in order to investigate if visualization, by means of an interactive technology environment (Geogebra), can…

Avcu, Seher; Çetinkaya, Bülent – International Journal of Mathematical Education in Science and Technology, 2021
This study explored prospective middle school mathematics teachers' developing understanding of geometric transformations through designing and implementing an instructional unit in a technology supported classroom environment. The instructional unit including seven activities was developed by considering past research on learners' pre-existing…

Hernández, Alexánder; Perdomo-Díaz, Josefa; Camacho-Machín, Matías – International Journal of Mathematical Education in Science and Technology, 2020
The initial training of mathematics teachers in Spain can start in the final year of the mathematics degree when the students, and future teachers, select courses related to teaching the discipline. At that time, since over the next two years they will probably be certified to enter the profession, it is worth asking oneself what mathematical…

Zambak, Vecihi S.; Tyminski, Andrew M. – International Journal of Mathematical Education in Science and Technology, 2020
With the emergence of new instructional technologies, pre-service teachers are expected to develop Mathematical Technological Knowledge (MTK), which we define as teacher knowledge of technology developed as a result of exploring mathematics with technology. We examined 16 middle grades pre-service mathematics teachers' (PSMTs) MTK within a…

Fung, Chak Him; Poon, Kin Keung – International Journal of Mathematical Education in Science and Technology, 2021
This study consisted of two stages. In stage A, 38 students were divided randomly into an experimental and a control group. The experimental group received lectures assisted by dynamic geometry software (DGS) and the control group received lectures using chalk and blackboard. The effects of DGS on metacognition and its components were…

Glassmeyer, David; Brakoniecki, Aaron; Amador, Julie M. – International Journal of Mathematical Education in Science and Technology, 2019
Including opportunities for students to experience uncertainty in solving mathematical tasks can prompt learners to resolve the uncertainty, leading to mathematical understanding. In this article, we examine how preservice secondary mathematics teachers' thinking about a trigonometric relationship was impacted by a series of tasks that prompted…
