This case study aims to explore how male and female Indonesian mathematics teachers enact decision-making processes in teaching High-Order Thinking Skills (HOTS). Non-random purposive sampling technique was used to select the participants. The participants involved in this study were two Indonesian mathematics teachers who teach HOTS in their…

It is imperative teachers use evidence-based practices to instruct all learners. Yet, there are limited reviews focused on educational practices to support secondary students with learning disabilities in algebra. This evidence-based systematic review focused on research published in peer review journals between 1999 and 2019. Eighteen studies…

In this paper, we investigate how a research mathematician conjectures and proves when conducting her research. To be precise, the aim of this study is to achieve a comprehensive understanding of the way this research mathematician develops these mathematical practices and thus gain insight to improve the teaching and learning of these two…

Making connections between the representations of trigonometric functions and an interpretation of graphs of the functions are major challenges to many students. This study explores the effectiveness of the GeoGebra on grade 12 students' success in making connections between the representations of trigonometric functions and the interpretation of…

The relevance of the problem under study is due to the need to modernize the professional training of future teachers in the context of the implementation of the competence approach. One of the most effective methods for improving the training of a modern teacher is his subject and methodological training. In modern times, competitive teachers are…

The competency-based approach conceives mathematics as a necessary tool for dealing with daily-life tasks. Many studies have focused on examining the low math competency people show when solving problems in real-life contexts, but rarely characterize the type of mathematics needed in these contexts and how people use this mathematics. The current…

We frame teachers' contextualization of mathematics (CoM) as a classroom-based identity resource. We explore CoM in secondary classrooms in the segregated school landscape of the US, focusing specifically on schools that serve primarily low-income Black and Latinx students. We review literature that discusses commonly-cited affordances for CoM…

An important part of the mathematics syllabuses at the secondary school level in most countries is the concept of function. However, secondary school students often experience difficulties with this concept. These difficulties are well-known in the research literature. The study applies the mathematical knowledge for teaching (MKT) framework,…

This study aimed at investigating the challenges of teaching mathematics to visual impaired students in school of the blind, a case study of some selected schools for the visually impaired. Questionnaire and interview were used for data collection from the respondents. The hypotheses in the study were tested using t-test with a-level of 0.05…

This study aims to develop multiple intelligence-based textbooks seventh grade junior high school students with material on equations and inequalities. It is hoped that the results of the development of this textbook can improve student learning outcomes, especially in the ability of mathematical representation. The population used was students of…

This research aims to provide android applications to empower mathematics teachers' information and communication technology readiness. The purpose is to facilitate them, due to availability and widely distribution of Android devices, to support them in Bring Your Own Devices (BYOD) practice in mathematics education. The method used is survey to…

The aim of the study is to teach the concept of function using cryptology and to investigate whether it provides support to students who have difficulty integrating this topic into everyday life. The study's research group consisted of 50 elementary school teachers in the department of mathematics education at a public college in Ankara. Since the…

This study investigated mathematics teachers' beliefs about the nature of mathematics and the contributory factors shaping them. A survey of 200 trained and untrained mathematics teachers from public and private schools was carried out in Karachi Pakistan, a context with a strong influence of religion on the socio-cultural practices of the people.…

Education currently only prioritizes mastery of scientific aspects and students' intelligence. Math problems are still related to fictitious general knowledge. For this reason, local wisdom-based learning is needed whose learning is packaged using objects, events, and various things that are close to students' lives to raise the local potential of…

The main goal of this study was to analyze the contribution of predictors of both domain-general (working memory, processing speed, and receptive vocabulary) and domain-specific variable (estimation and magnitude comparison) processes to informal mathematical performance (numbering, comparison, calculation, and understanding of concepts) in…
