Textbooks are one of the main resources for teaching and learning mathematics. This study examines the presentation of angle topics in 4th-grade mathematics textbooks in Indonesia and Singapore. The analysis focused on the general characteristics of the textbook and the nature of the mathematical tasks presented. The results showed that Indonesian…

This research aims to test: (1) the effectiveness between problem posing learning model with Indonesian realistic mathematical education approach and problem posing learning model on written mathematical communication skills; (2) the effectiveness between field-independent and field-dependent cognitive styles on written mathematical communication…

Traditional houses are part of the culture of every country. Indonesia is a country that has a variety of traditional houses. The traditional Banyuwangi house is known as the "Using" house. This house can be explored in terms of ethnomathematics and used as part of learning mathematics. This research is focused on knowing and describing…

Mastery of mathematical literacy is essential for developing life skills in the 21st century. Mathematical literacy is even more critical in elementary schools as it forms the basis for mastery at the junior and senior high school levels. Elementary school students differ in their characteristics from students at the higher education level. They,…

Proof, as a central and integral part of mathematics, is an essential component of mathematical education and is considered as the basic procedure for revealing the truth of mathematical propositions and for teaching productive reasoning as part of human civilization. Is there therefore room for conjectures in mathematics? In this paper after…

Meaningful and enjoyable experiences are important in the education of children. In this qualitative case study, the garden program (incl. market garden shop, garden care, Kid's Kitchen, and chicken coop) in one Australian primary school was explored to determine its impact on the mathematical learning of children. Data were collected using focus…

Mathematics is mostly related to human life, thus, humans are required to have the mathematical understanding ability in solving life problems since in the elementary school age. Therefore, mathematics learning at school should have relevance value to construct mathematical concept that can be used in real life. Innovative mathematics learning…

School life in England (and beyond) is temporally structured, with learning planned as a time-limited activity, both within lessons and across units of work. Discourses of performativity and measurement pervade school life in many societies and, what we call "regulated time" controls school-based learning. In particular, primary…

Background: Several isiXhosa home language (HL) learners are excluded from meaningful mathematics learning because they are taught in English. Not only do teachers lack epistemological and pedagogical confidence in using multiple languages when teaching mathematics, but there are no mathematical registers for African languages that allow for…

Over the years, several frameworks and lesson observation protocols have been developed to ensure objectivity and consistency when determining the quality of a mathematics lesson. Frequently, the frameworks do not agree on the benchmarks for assessing and describing the quality of a lesson. This puts mathematics education researchers in a dilemma…

Previous research on bilingual mathematics education has proposed that as children "language mathematics" they use multiple sources of meaning. In this paper, we focus on lexical inventions--bilingual children's made up words that are not formally defined or used but follow the phonology and morphology of a language--as a source of…

The fact that the mathematics course is abstract, that it is not possible to associate it with daily life, and that it is impossible to concretize abstract expressions causes a prejudice against the this course and leads to a decrease in the academic achievements of students. It is seen that throughout history, various studies have been carried…

The present research focuses on analyzing how fourth-grade elementary school students (ages 9 to 10) solve and interpret the result of non-routine problems, precisely division measurement and division-partition with remainder. The methodology is qualitative, with a descriptive and interpretative approach. The information was collected using a…

When language is defined narrowly in mathematics classrooms, racially and linguistically minoritized students in classrooms could be systematically positioned as "learners of deficiency." Recent scholarship calls for expanding the notion of language to emphasize embodied expression of mathematical ideas. Taking a critical perspective to…

This study examined Cho's dynamic system model of creative problem-solving ability in a sample of 112 gifted and non-gifted students. The cluster analysis and t-test results indicated that students should be categorized into high and low performance groups. Students who scored three points or more across all attributes also had a higher likelihood…
