We administered specially-designed, free-response mathematics tasks to primary students (N = 583, ages five to 12 years old). Our focus was on whether (i) the children's responses could be reliably assessed, and (ii) the responses could provide insights into children's mathematical thinking. We used a contemporary comparative judgement technique,…

This ethnographic study explores how elementary school children's participation in a culturally diverse music program, which featured their active engagement in group music-making and their acquaintance with the cultural-historical context of the music, affected them on interpersonal, collective, and social levels. The study focuses on the…

The paper explores one episode from a larger study, where a multilingual student (10-year-old) described her understanding of what makes a shape 2D or 3D. Bakhtin's dialogic theory and Garfinkel's ethnomethodology inform the theoretical framework. Transcribed data of the episode is presented, which is analysed at micro-level and macro-level. The…

This article addresses the pressing issue of food waste by focusing on the development of young adolescents' food waste literacy. The concept of "food waste literacy" (FWL), defined as the literacy for the judicious use of food, encompasses knowledge, attitudes, values, and behaviours related to food waste. The article presents a study…

The interactional role of language use in the mathematics classroom is explored in the last few decades. This paper adds to the knowledge base by exploring different ways of talking that children and their teacher use in a New Zealand primary geometry English-medium classroom. Bakhtin's concept of speech genres is used for an analysing transcript…

Advances in learning approaches can enhance deeper levels of mathematical thinking and engagement through the use of new digital environments and technologies. The growing utilisation of portable digital devices in schools has meant there are enhanced tools to support mathematical learning and understandings. This article focused on those who work…

The national COVID-19 lockdown during school Term 1 and continuing in Term 2 2020, provided a unique context to investigate?children's experiences of informal, everyday learning in their household bubble. In Terms 3 and 4, 178?children in Years 4-8 from 10 primary schools agreed to participate in a group art-making activity and?an individual…

In 2012 a new education monitoring system called the National Monitoring Study of Student Achievement (NMSSA) began collecting information about the achievement of Year 4 and Year 8 students enrolled in English-medium schools. Over the last 5 years it has had contact with over 20,000 students from more than 1,000 schools. This Assessment News…

As a facilitator of the Incredible Years for Teachers Programme (IYT), I have found that the classroom management strategies participant teachers learned during the 6-month programme period have not been embedded and sustained in their use through time. This inquiry investigated the benefits and barriers to IYT being spontaneously, consistently…

Whilst prior research has identified children as avid users of new technologies, insufficient studies have explored their patterns of use. This paper investigates how New Zealand pre-teens use technology out of school and identifies a typology of technology use. Two hundred and twenty four children between 10 and 12 years of age completed a…

This article presents the findings of a case study undertaken with the year 5 girls in one school to investigate their experiences and understanding of covert intimidation, as well as the effects and impact of these practices in the school setting. The findings of the study were obtained from the analysis of interviews, researcher-generated…

This document contains the fifth volume of the proceedings of the 30th Conference of the International Group for the Psychology of Mathematics Education. Conference presentations are centered around the theme "Mathematics at the Centre." This volume features 59 research reports by presenters with last names beginning between Sac and Zaz:…
