One of the factors that influences how students learn mathematics is their mathematics-related beliefs. Mathematics-related beliefs are important, but in Indonesia, there has been little research on mathematics beliefs in elementary schools and in relation to grade level and gender. This study aims to determine the general profile of elementary…

This qualitative multi-site case study explores the self-identified traits of four Philadelphia schools that demonstrate growth in grade four proficiency on the Math Pennsylvania System of State Assessment (PSSA). Obtained proficiency/advanced scores on the PSSA show a drop from third to fourth grade cohorts during 2017, 2018, and 2019. In…

Special tasks for pre-service teachers (PSTs) in university mathematics courses ("interface tasks") are a common innovation in recent years to overcome the second discontinuity. By this, we mean tasks that are situated by typical everyday challenges of mathematics teaching and in which PSTs must use their mathematical knowledge and…

Children's early accuracy on place value (PV) tasks longitudinally predicts their later multidigit calculation skills. However, another window into children's emerging base-ten concepts is the pattern of errors -- "smart errors" -- they exhibit on these measures. Past research has speculated that these smart errors -- similar to invented…

The aim of this study was to analyze the joint, relative, and unique predictive value of students' prior knowledge of mathematics (knowledge of fractions and ability to divide natural numbers) and general cognitive ability (fluid intelligence and working memory) upon general mathematics achievement in the last year of primary school. Seventy-five…

This paper discusses the relevance of using physical situations to introduce the concept of angles at elementary school. We compare the effectiveness of two geometry teaching sequences. In the first one (physical sequence), the pupils learned the angle concept by experimenting on the playground (i.e. mesospace) and then modelling the situation. In…

Long-standing and ongoing calls exist for making mathematics meaningful, relevant, and applicable outside the classroom. Major mathematics education organizations (National Council of Teachers of Mathematics [NCTM], National Council of Supervisors of Mathematics [NCSM], Association of Mathematics Teacher Educators [AMTE], TODOS: Mathematics for…

Based on an experiment carried out with 10- to 11-year-old pupils, this paper questions the place of imagination in a class activity using the history of mathematics. The study focuses on three groups of pupils who were offered three variants of the same activity based on base-60 counting (our time measurement system inherited from the…

The definitions serve the purpose of communication and preservation of knowledge in scientific inquiry. However, it is quite often to perceive number sense concept without well-accepted definitions in the field of mathematics education research. Despite the mentioned issue, the current literature on children's number sense provides a glean for…

In this paper, we analyse the results of an experience designed and implemented to evaluate the epistemic and cognitive conflicts identified in the study of proportionality, carried out by a group of 21 students in their last year of primary education. Initially the students exhibit difficulties to recognize situations where proportionality can be…

Computational thinking (CT) has become central to introducing digital artefacts for educational use. However, little is known about implementing CT in the mathematical school curriculum, and many educational staff members have not been introduced to CT in their initial training. Introducing CT in an educational setting calls for interventions that…

Teachers act as role models and through their activities are active co-designers of future generations. Independent thinking and taking responsible, sustainable actions form the basis for a vibrant society. Entrepreneurship skills can already be fostered in primary school children. This requires well-trained primary school teachers. The following…

"Balai Besar Guru Penggerak Daerah Istimewa Yogyakarta (BBGP DIY)" conducted a professional development course aimed at enhancing primary school teachers' capacity to develop and implement STEM lesson plans in their classrooms. As part of the course, teachers were asked to record their lessons, which were later analysed to identify the…

Most research has focused solely on understanding high school or college students' mathematical creative thinking abilities while understanding younger students' creative thinking in mathematics was ignored. These studies of older students have focused mainly on students' creative products rather than creative processes. The authors of the present…

Fraction competence is essential for learning algebra and pursuing careers in science, technology, engineering, and mathematics. However, many children have difficulty using fractions, especially those struggling with mathematics. In this study, we examined the effect of a Tier 2 multicomponent fraction intervention for fifth graders, using a…
