Burçak Boz-Yaman – Electronic Journal for Research in Science & Mathematics Education, 2024
This study aims to examine changes in students' achievement in geometry, attitude towards geometry, and their self-efficacy perception of geometric knowledge while working on paper folding activities through an experimental research methodology. The sample for this experimental study was 108 ninth-grade high school students. The study's data were…

Bergström, Tove; Gunnarsson, Gunilla; Olteanu, Constanta – International Journal of Mathematical Education in Science and Technology, 2023
This article is intended to contribute to greater knowledge regarding the importance of flow and the time used to perform an activity, with a focus on students' mathematical experiences of 3D bodies. Thirty-one 9th-grade students took part in the study. Flow and variation theory was used in the analysis of lesson observations, submission tasks,…

Fahrurozi, Achmad; Maesaroh, Suci; Suwanto, Imam; Nursyahidah, Farida – Journal of Research and Advances in Mathematics Education, 2018
This research aims to produce a Learning Trajectory Based Instruction (LTBI) that can help the ninth grade students understand the concept of congruence of the two-dimensional shape by examining Lawang Sewu as one of Central Java historical buildings. LTBI is defined as a teaching and learning trajectory that uses Hypothetical Learning Trajectory…

Miles, Victoria L. – Mathematics Teaching in the Middle School, 2014
One of the most common household polyhedra is a cereal box. For over 100 years, American companies like Kellogg's™ have packaged cereal in containers shaped like rectangular prisms. Why is a rectangular prism the most commonly used solid for holding cereal? Would another design work equally or more efficient? This article describes an…

Ada, Tuba; Kurtulus, Aytaç; Yanik, H. Bahadir – International Journal of Mathematical Education in Science and Technology, 2015
The aim of this study was to observe the development process of the concept of a parabola in Taxicab geometry. The study was carried out in two stages. First, some activities related to Euclidean geometry and Taxicab geometry were designed based on concept development and real-life applications, and they were administered to a ninth-grade student.…
