Designing to transform: High school students’ reasoning with geometric transformations in an authentic real-world project

Using learning progression-based interactive dynamic geometry instruction to develop quadrilateral reasoning in preservice teachers

This study investigated the learning of K–8 preservice teachers (PTs) while enrolled in an in-person class that was integrated with an online, individualized, and interactive Dynamic Geometry curriculum (iDGi), built from empirically derived learning progressions (LP). The research examined PTs’ developing understandin...

GEOMETRY EMERGING FROM STUDENTS’ LIVED EXPERIENCES: THEORY AND PEDAGOGICAL INTERVENTION IN THE SIXTH GRADE OF ELEMENTARY SCHOOL

Geometry teaching can become more meaningful when connected to the spaces experienced by students, thereby facilitating the understanding of concepts that are often presented in an abstract manner. In this context, this experience report addresses the following research question: How can a pedagogical proposal based on...

A Realistic mathematics education approach in 3D geometry: module development and evaluation

Flipped Classroom and Meaningful Learning: A Pedagogical Proposal for Teaching Spatial Geometry in High School

Geometry plays a fundamental role in the teaching and learning of mathematics, providing essential tools for solving real-world problems, particularly by enabling students to visualize and understand three-dimensional objects. This study presents a didactic sequence designed and implemented with secondary school studen...

Relational reasoning in understanding mathematics concepts through local culture and learning styles

Students’ prior knowledge is shaped by their cultural environment before entering formal education. However, the utilization of local culture in class remains underexplored. This study analyzes students’ relational reasoning in understanding mathematics concepts based on local culture and different learning styles usin...

Innovation in RME-Based Interactive Media to Support Understanding of 2D Shapes and Critical Thinking

This study pioneers a structured, digital RME environment that seamlessly merges contextual problem-solving with interactive visualization explicitly tailored for elementary plane geometry, thereby supporting meaningful learning and higher-order cognitive skill development in primary education.
