This study focused on improving students' learning mathematical of proofs and proving by using combinations of proof strategies that span different levels of understanding of proof structure; we refer to these as 'level-spanning proof-production strategies'. We analysed the level-specific proof-production strategies evident in the lessons and…

Children's attitudes are shaped by the information to which they are exposed. To foster improved peer relationships in inclusive settings, there is a need for typically developing children to exhibit positive attitudes toward peers with disabilities. The aim of this study was to examine the relationship between children's attitudes toward their…

It is important to identify suitable parameters to measure and assess the quality of physical education. This paper aims to understand such measuring tool by focusing on professional perceptions and areas of concern of quality physical education (QPE). The research survey includes data gathered from 799 professionals in 11 cities in Asia. These…

Many students are not good at geometric proofs. One reason for this is that it is possible to memorize the proof procedure explained by the teacher without understanding the structure of a geometric proof. So far, we have developed a web-based application that supports the understanding of the "structure of geometric proofs" in junior…

This paper conducts a theoretical examination of an evidence-based approach (EBA) to research on language policy and language-in-education policy (LPLEP), as well as a methodological examination of the feasibility of evidence-based LPLEP research based on actual studies. Theoretical scrutiny, based on EBA's core concepts--evidence hierarchy,…

Amongst important and under-researched questions are how introductory lessons can be designed for teaching initial proofs to junior high school students, and how such lessons enrich students' understanding of proofs. With a view to improving the learning situation in the classroom, in this paper we report on the various functions of introductory…

Proof and proving are important components of school mathematics and have multiple functions in mathematical practice. Among these functions of proof, this paper focuses on the discovery function that refers to invention of a new statement or conjecture by reflecting on or utilizing a constructed proof. Based on two cases in which eighth and ninth…

The article explores the use of the Social and Emotional Health Survey-Secondary version (SEHS-S) with a sample of 975 Japanese students in Grades 7-9 attending schools located northwest of Tokyo. A confirmatory factor analysis using half the sample confirmed the four-factor structure of the SEHS-S, and further analyses verified its second-order…

This study investigated the reliability and validity of the Multidimensional Scale of Life Skills in Late Childhood, an instrument designed to measure a concept similar to "zest for living" in late childhood. A total of 1,888 elementary school students in the 4th, 5th, and 6th grades residing in urban and suburban areas as well as in…

The purpose of this study is to explore how primary school students reexamine their conjectures and proofs when they confront counter-examples to the conjectures they have proved. In the case study, a pair of Japanese fifth graders thought that they had proved their primitive conjecture with manipulative objects (that is, they constructed an…

This study was an investigation of student beliefs about their EFL education, and it was based upon the subjective task value component of the expectancy-value theory, a prominent theory of achievement motivation. The participants were three cohorts of Japanese public elementary school students (Cohort 1 from 2008; Cohort 2 from 2009; and Cohort 3…

These proceedings contain the papers of the 16th International Conference on Cognition and Exploratory Learning in the Digital Age (CELDA 2019), held during November 7-9, 2019, which has been organized by the International Association for Development of the Information Society (IADIS) and co-organised by University Degli Studi di Cagliari, Italy.…

We are delighted to welcome you to the International Psychological Applications Conference and Trends (InPACT) 2017, taking place in Budapest, Hungary, from 29 of April to 1 of May, 2017. Modern psychology offers a large range of scientific fields where it can be applied. The goal of understanding individuals and groups (mental functions and…

The aim of the 2018 International Association for Development of the Information Society (IADIS) Cognition and Exploratory Learning in the Digital Age (CELDA) conference was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There have been advances in both cognitive…

This document is the fourth volume of the proceedings of the 29th Conference of the International Group for the Psychology of Mathematics Education. Conference papers are centered around the theme of "Learners and Learning Environments." This volume features 42 research reports by presenters with last names beginning between Mul and Wu:…
