There is ongoing debate regarding what performance on the number line estimation task represents and its role in mathematics learning. The patterns followed by children's estimates on the number line task could provide insight into this. This study investigates children's estimation patterns on the number line task and assesses whether mathematics…

The COVID-19 pandemic disrupted education worldwide as educational systems made the decision to close schools to contain the spread of the virus. The duration of school closures varied greatly internationally. In this study, we use representative trend data from more than 300,000 students in 29 countries to examine whether the cross-country…

This study aims to apply the differential item functioning (DIF) technique with the deterministic inputs, noisy "and" gate (DINA) model to validate the mathematics construct and diagnostic attribute profiles across American and Singaporean students. Even with the same ability level, every single item is expected to show uniform DIF…

The main purpose of this study was to explore major factors at student and teacher/school levels affecting middle-school students' science self-efficacy among countries with high science academic performance levels in PISA 2015 data by using various regression algorithms of machine learning and multilevel latent profile analysis (MLPA). Out of…

Through the use of the Program for International Student Assessment's (PISA) Global Competence results, the Economic Intelligence Unit's (EIU) Democracy Index ratings, and centralization-decentralization spectrum rubrics, this dissertation shows the association between level of democracy and education system, and the association of these variables…

Unfavorable test-taking behaviors, such as speededness and disengagement, have long been a validity concern for large-scale low-stakes assessments. Understanding the presence and extent of such behaviors is important for ensuring the validity of inferences based on test scores. This study examined test-taking behaviors using item response time…

The ultimate aim of this research was to explore the contribution of teacher preparedness or readiness (in terms of their academic background, confidence in teaching science and career satisfaction) towards the achievement in science among Malaysian and Singaporean eighth-graders. The TIMSS 2011 international assessment of student achievement at…

Several studies have been published on disengaged test respondents, and others have analyzed disengaged survey respondents separately. For many large-scale assessments, students answer questionnaire and test items in succession. This study examines the percentage of students who continuously engage in disengaged responding behaviors across…

Improving schooling by reducing achievement gaps based on family background has been on the agenda of school governance worldwide for more than three decades. International benchmarking like the OECD's Programme for International Student Assessment (PISA) is used to find models of best practice in effective school governance. Enlarging school…

In this study, the Computer Science (CS) education in K-12 of the countries in the "Asia-Pacific region", which are among the top 10 in PISA, and CS education of Türkiye were investigated. PISA is conducted to assess science, mathematics, and reading skills. PISA, which is carried out every 3 years by the OECD, evaluates 15-yearold…

This study delves into the determinants of emotional control among 6606 Singaporean students, aged 15 years old, participating in the Programme for International Student Assessment (PISA) 2022. It aims to explore the various factors contributing to emotional control, utilizing multiple regression analysis on data from PISA's comprehensive 2022…

One of the main objectives of international large-scale assessments is to make comparisons between different countries, education policies, education systems, or subgroups. One of the main criteria for making comparisons between different groups is to ensure measurement invariance. The purpose of this study was to test the measurement invariance…

The present study explores the validity of inferences that may be drawn from the Trends in International Mathematics and Science Study (TIMSS) learner achievement data by measuring the South African curriculum-TIMSS alignment for the Grade 8 science assessments from 2007 to 2019. The Singapore curriculum--TIMSS alignment indices are a fair…

This comparative study investigated the associations between instructional practices and students' reading performance among 10 top performing regions that participated in the Program for International Student Assessment (PISA) 2018. A nationally representative sample consisting of 80,016 15-year-old students from 5 Asian regions (B-S-J-Z [China],…

This study aims to identify the profiles regarding students' familiarity with information and communication technology (ICT) and their relationships to reading literacy and background variables for high-performing countries in PISA 2018. We distinguished four classes in each of the six countries (Estonia, Hong Kong, Ireland, New Zealand, Poland,…
