In this study, a paper folding activity task, which involved reaching the Pythagorean Theorem with a series of steps was designed. The aim of the task is to reach the Pythagorean Theorem with folding activities by deductive reasoning and logical inference. The study aimed to examine the effectiveness of the task and to share the patty paper…

Learning Transformation Geometry (TG) needs a more informal approach to concern situational problems. This study aims to develop actionable knowledge of TG in the form of design related to context and yet general enough to use digital manipulative activities in new situations. We propose such knowledge in the form of conjectured Local…

South African learners' performance in mathematics, both locally and internationally, has raised significant concerns, particularly in the realm of algebra. To address this issue, a mixed-methods study was conducted to explore the effectiveness of using algebra tiles to teach algebraic expressions. The study aimed to investigate algebraic…

This paper aims to present ways in which origami can be used in the mathematics classroom. Origami provides powerful tools for examining mathematical concepts. The authors explain how origami can be used in senior high school and tertiary levels to explore a Platonic octahedron by focusing on connections between mathematical topics. The folding…

The teaching of first-degree equations is a key point in secondary school curricula and requires the careful planning and selection of appropriate teaching materials. On the other hand, dyslexia, a specific learning disability, is increasingly common in the classroom. Thus, in the context of inclusion, the teaching methodology used by the…

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…

How do people use objects and gestures to shape scientific argumentation? This paper engages the concept of "entanglement" as a heuristic for considering the potentials and constraints that gestures and materials create for interactants. Drawing on video recorded data from an academic-year-long linguistic ethnography of a high school…

Finding teaching methods that foster students' development of geometric thinking and visualization skills is still a current challenge. This study analyses the effects of the combined use of paper folding and dynamic geometry on high school students' geometric thinking and visualization skills. A quasi-experimental study pretest/post-test design…

Xerogels, exemplified by silica gel, are substances formed by drying gels, resulting in a loss of their internal solvents. Understanding the production and properties of xerogels is crucial, owing to their widespread applications. Xerogel chemistry is widely utilized in several substances; therefore, understanding this chemistry is extremely…

The hearing impairment can result in students having difficulty accepting learning. Obstacles Students in special schools when observing the understanding the numeracy skills. Students have problems sorting numbers and adding numbers from 1 to 10. Numeracy skills are an introductory lesson in learning mathematics. Several studies have shown that…

All students, including students with learning disabilities, deserve a mathematics education that successfully prepares them for their future endeavors. This preparation includes effective instruction in algebra, which is known as the gatekeeper to post-secondary schooling, employment, and constructive citizenry. However, majority of students with…

Providing all students with equitable treatment and access has been a cornerstone of mathematics education reform (Association of Mathematics Teacher Educators, 2015; National Council of Teachers of Mathematics, 2014). Studies in mathematics classrooms show that using hands-on and interactive materials (i.e., "manipulatives") support…

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…

Individuals engage in purchasing skills on a daily basis. Regardless of the curricular focus of secondary students with intellectual and developmental disabilities (IDD; i.e., academic or functional), possession of life skills is important. In this single case design study, researchers examined the provision of online instruction to three U.S.…

This study was an investigation of the use of manipulative materials in the mathematics classroom. The researcher guided students to create paper triangles, which were then used as a manipulative to calculate the sum of the interior angles of a triangle. On pre- and post-measures of quantitative data, although the data indicated a positive…
