This paper reports an intervention study in the teaching of fraction concepts at a village school in Hong Kong. The classes consisted of 60 Grade three students with different cultural backgrounds, including African, Chinese, Filipino, Korean, Nepalese, and Pakistani. The study represents one of the relatively few studies that investigate the…

Measurement estimation skills are relevant for our everyday life and should be addressed in the mathematics classroom. Although students' measurement estimation skills were examined in several empirical studies, a structure model to describe these skills is still missing. The current research aimed at analyzing the structure of length estimation…

In the last 5 years, there have been several literature reviews or meta-analyses investigating various aspects of STEM education; however, they have investigated a specific aspect of STEM, e.g. robotics, or digital games, or Early childhood, or Teacher perspectives. In addition, a broad-reaching review on STEM integration has not been conducted in…

This case study investigates, at three Swedish schools, primary school students' knowledge of the equal sign. The schools were chosen as representatives of schools whose students have different socioeconomic backgrounds. The data consist of Grade 3 and 6 students' responses to an assessment form based on Matthews et al. ("JRME,"…

Teaching in ways responsive to the cultures of our students is vital towards enhancing equity of access to mathematics achievement and putting educational policy into practice. New Zealand has the largest group of Pasifika people in the Western world, a multi-ethnic group of indigenous people from Pacific Island nations who have differing cultural…

This article describes part of the findings of a teaching experiment whose objective is to investigate the algebraic abilities of elementary students when they solve situations that involve a functional relationship. In particular, we focus on describing the use and meanings attributed to letters by third-year primary school students when faced…

The aim of this article was to determine the factors in teachers' actions that could explain differences in the emotional atmosphere of primary school classrooms. Based on pupils' drawings about their mathematics lessons, we analyzed both the pupils' and their teachers' actions, including pupils requesting help, sitting alone, and talking about…

Explaining appears to dominate primary teachers' understanding of mathematical reasoning when it is not confused with problem solving. Drawing on previous literature of mathematical reasoning, we generate a view of the critical aspects of reasoning that may assist primary teachers when designing and enacting tasks to elicit and develop…

Data collection, organization, and analysis are indispensable means of seeking solutions during the process of inquiry. Representations (called inscriptions by some educators) including graphs, tables, photographs, and equations are powerful ways of arranging and displaying data in visual form. This study aims to analyze quantitatively the use of…

The science vocabulary from a science curriculum standards document (Ministry of Education Ontario, 2007) was classified by morphological developmental level and compared to the grade level topics of the curriculum (grades 1 to 8). Descriptive statistical analyses highlight the complex nature of science vocabulary and the incompatibilities between…
