This study aimed to examine the effect of early numeracy activities at home on children's mathematics achievement in fourth grade. It also examined the mediating effects of early numeracy competencies and self-efficacy beliefs in mathematics on this relationship. The study used Trends in International Mathematics and Science Study (TIMSS) 2015…

The purpose of this study is to compare and contrast student, teacher, and school factors that are associated with student mathematics achievement in South Korea and the United States. Using the data from the Trends in International Mathematics and Science Study (TIMSS) 2011, this study examines factors that are linked to teachers who deliver…

This research aims to scrutinize the moderating effect of teacher interaction on the relationships between students' self-efficacy and achievement in mathematics in three countries, Korea, Singapore, and the USA. We analyzed the Trends in International Mathematics and Science Study (TIMSS) 2015 data with hierarchical linear modeling. The findings…

This study investigated the effect of teacher academic support, teacher-student relationship, and teacher achievement pressure on maths class engagement via maths self-efficacy. This study examined the relationships among these variables through four structural equation models and identified the model with the best fit. Data of 6,927 students from…

Background: In the Korean educational system, academic achievement is one of the crucial factors in assessing a student's academic ability for postsecondary education. Thus, many researchers have been studying ways to improve students' academic achievement. Objective: The purpose of this study was to examine the relationship between students'…

This study makes an important contribution to an expanding body of international comparative studies by exploring factors predicting differences in science and mathematics achievement by students in Turkey and the Republic of Korea on the 2011 TIMSS assessment. While these countries are similar with regards to population size, cultural beliefs…

The purposes of the present study were to investigate (a) how the subjectively perceived achievement goals of significant others would predict the academic self-efficacy and achievement goals of Korean adolescents and (b) how those self-efficacy and achievement goals in turn predicted their achievement. We also compared these predictive…

This study investigates the structure and cross-cultural (in)variance of mathematical self-beliefs in relation to mathematics achievement in two world regions: Confucian Asia (Singapore, South Korea, Hong Kong and Taiwan) and Europe (Denmark, The Netherlands, Finland, Serbia and Latvia). This is done both pan-culturally and at a multigroup-level,…

The effects of two interventions, one for parents (Intervention-P) and the other for students (Intervention-S), on children's math motivation were examined. Intervention-P involved the sending of six letters to parents over 3 weeks to promote their growth mindset, gender-fair beliefs, and expectations for their child's success in math.…

The present study investigated whether self-estimation bias in maths competence was associated with motivational costs or benefits, concurrently and prospectively, and whether these associations depended on students' achievement levels. Participants were 2,807 seventh grade students who were reassessed after 2 years to examine the longitudinal…

The Trends in Mathematics and Science Study (TIMSS) is a time-series database, which provides an early warning for necessary curricular reforms in mathematics and science subjects and offers an opportunity for schools and policymakers to reflect on the effectiveness of educational changes. It provides vital data for governments and researchers to…

The Program for International Student Assessment (PISA) by the OECD measures student study time during formal school periods and during periods of out-of-school-time (OST). The purpose of these items is to account for differences in country to country achievement levels. However, analyses of the impact of additional study time on student…

Research studies have identified several factors related to mathematics achievement of students in Korea. Further, results from the Trends in International Mathematics and Science Study (TIMSS) assessments have shown that instructional practices and beliefs about mathematics were significantly associated with mathematics achievement of students in…

This book provides a unique international comparative perspective on diverse issues and practices in mathematics education between and among the US and five high-performing TIMSS education systems, Japan, China, Singapore, South Korea, and Taiwan. The book offers multiple perspectives on the important factors that contribute to mathematics…

Validity of the 2 x 2 achievement goal framework for school-aged children and adolescents was examined, using self-report responses from 1,196 Korean elementary and middle school students. Confirmatory factor analysis models hypothesizing 4 distinct achievement goal factors demonstrated the best fit in all age groups. Nevertheless, achievement…
