Background: Life satisfaction is a key component of students' subjective well-being due to its impact on academic achievement and lifelong health. Although previous studies have investigated life satisfaction through different lenses, few of them employed machine learning (ML) approaches. Objective: Using ML algorithms, the current study predicts…

This study aimed to evaluate the item model fit by equating the forms of the PISA 2018 mathematics subtest with concurrent common items equating in samples from Türkiye, the UK, and Italy. The answers given in mathematics subtest Forms 2, 8, and 12 were used in this context. Analyzes were performed using the Dichotomous Rasch Model in the WINSTEPS…

The purpose of this research is to determine whether PISA 2018 mathematical literacy test items show a differential item functioning across countries. For this purpose, only the items in booklet number three were examined using the MIMIC method with Latent Class Analysis (LCA) approach. PISA 2018 tests are mostly developed in English. Therefore,…

The purpose of this study is to examine the effect of missing data imputation methods, namely regression imputation (RI), multiple imputation (MI) and k-nearest neighbor (kNN) on differential item functioning (DIF). In this regard, the datasets used in the research were created by deleting some of the data via the missing completely at random…

The purpose of this study is to examine the predictive effects of epistemological beliefs about science and informal reading of scientific texts on students' future-oriented optimism on the issue of climate change. Future-oriented climate change optimism is defined as encompassing "hope" and "anticipation" about the climate…

This study utilised 2015 PISA data from the United Kingdom and Hong Kong to examine the relations between outside school ICT use for learning and science performance through a mediation model. The results uncovered three key findings: Firstly, ICT use for learning exhibited negative total effects on science performance in the United Kingdom,…

The Digital High Stakes Assessment Programme in Cambridge University Press & Assessment is developing digital assessments for UK and global teachers and learners. In one development, the team are making decisions about the assessment models to use to assess computing systems knowledge and understanding. This research took place as part of the…

Many education systems aim to provide learning opportunities to all students regardless of their backgrounds in order for them to realise their potential. Education systems are expected to break down barriers to social mobility. However, too often, children are not given enough opportunities to succeed, to pursue their interests, or to develop…

In recent years, self-theories such as growth mindset and resilience have gained interest as they have a sizable influence on achievement and school-related motivation. The aim of this study is to investigate the relationship between immigrant students' growth mindset, resilience, and science achievement in PISA 2018 by considering the mediating…

Reviews of social comparison processes in school contexts have concluded that individual differences in propensity to compare with others are likely to be important in the classroom, but that there is a paucity of evidence testing this key proposition. To address this gap, we developed and validated a new measure of propensity to engage in…

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…

In Comparative Judgement (CJ) exercises, examiners are asked to look at a selection of candidate scripts (with marks removed) and order them in terms of which they believe display the best quality. By including scripts from different examination sessions, the results of these exercises can be used to help with maintaining standards. Results from…

This dissertation in practice explores the intersection of computer science education, specifically computational thinking and programming, with mathematics achievement among 15- year-old students in selected English-speaking countries. The research addresses a gap in understanding whether skills developed through computer science can positively…

Both formative assessment and growth mindset scholars aim to understand how to enhance achievement. While research on formative assessment focuses on external teaching practices, work on growth mindset emphasises internal psychological processes. This study examined the interplay between three formative assessment strategies (i.e. sharing learning…

In 2020 and 2021, schooling, like many other aspects of life, has been heavily affected by the ongoing coronavirus pandemic. During periods of school closure, education systems and schools have often been quick to organise remote support for home-based learning. But several observers have questioned the effectiveness of these schooling surrogates,…
