In STEM, learning skills and knowledge are learned simultaneously by students. Things that are different from the STEM aspect will require a connecting line that makes the four disciplines studied and applied simultaneously in learning. The utilization of local cultural characters in the STEM learning model is expected to provide solutions to the…

A qualitative research design comprising of open-ended questionnaires and focus group discussions was used to investigate learner-related variables that impede the integration of ethnomathematics approaches into the teaching and learning of geometry. Proportional stratified sampling and recruitment based sampling were used to select the 40…

In this study, we explore automated reasoning tools (ART) in geometry education and we argue that these tools are part of a wider, nascent ecosystem for computer-supported geometric reasoning. To provide some context, we set out to summarize the capabilities of ART in GeoGebra (GGb), and we discuss the first research proposals of its use in the…

For both first-year teachers and veterans, closing a lesson and assessing whether students met learning goals is a persistent challenge. This article explores how teachers using demanding, discourse-rich tasks can make informed decisions about when to move on in a lesson. Specifically, the author considers a "launch-explore-share and…

In this article we consider two triangles: one inscribed in another. We prove that the area of the central triangle is at least the harmonic mean of the areas of corner triangles. We give two proofs of this theorem. One is based on Rigby inequality and the other is based on the known algebraic inequality, to which we bring a new, geometric, proof.…

This paper describes a model of mathematics bianshi teaching using one problem with several solutions, changes, and applications in an inquiry-based classroom. Based on the model of mathematics bianshi teaching, the author discusses a class-room experience where one Chinese mathematics teacher takes a simple plane geometry problem to guide…

This article presents a reflection on a teaching experience involving the use of the Brügner tangram, an interesting but little-known manipulative material. It details an activity conducted as part of an undergraduate mathematics education course for prospective primary school teachers. The main objective of this paper is to present the…

This study explores indigenous pedagogical methods for teaching geometry in three secondary schools within the Kalomo District of Zambia. The study addresses three primary objectives: (1) exploring the utilization of Indigenous pedagogical methods in teaching geometry, (2) assessing the impact of integrating traditional knowledge on student…

This article outlines a series of lessons the author led to help students understand gerrymandering, which is the practice of drawing district boundaries to favor a particular group or party and which undermines the fairness of a representative democracy. These lessons were developed to capture student interest and engagement by linking…

Although studies have investigated the enablers and barriers of digital teaching and learning of STEM, the integration of digital technologies into teaching geometry -- one of the main mathematical concepts, is frequently ignored and does not garner much scholarly attention. To fill this specific gap, this small-scale qualitative study explored…

We introduce the concept of the "sequence of the ratios of convex quadrilaterals," identify some properties of these sequences and use them to provide new characterizations for some classic quadrilateral families. The research involves aspects of geometry, arithmetic and mathematical analysis, which converge to produce the results.

Do young children understand the complex mathematics in the petals of a daisy, the Fibonacci sequence in the spiral of a pinecone, the fractal geometry in the leaves of a fern, or the "golden ratio" in the seed pattern of a sunflower? Probably not, but they certainly can observe and recognize the patterns and compare them to similar…

Teaching geometry in the early years emerges along with maths activities but might be neglected sometimes. This research aims to identify preschool teachers' opinions on geometry teaching via using semi-structured interviews, and collected data analysed using content analysis. Seven female and three male preschool teachers were participated in the…

Mathematics achievement is positively associated with coding in the classroom. By making mathematical relationships visible to students as they code, teachers leverage rich connections between block-based computer programming and mathematical sense making. In this article, the authors describe strategies for adapting a Code.org lesson integrating…

This paper focuses on the importance of identifying students' Prior Knowledge (PK) for the teaching and learning of mathematics. Specifically, we present a framework that exemplifies the core elements teachers need to consider in relation to the purpose, design and implementation of learning experiences that enable PK to be activated and assessed.…
