Automated scoring for Korean essays utilizing the neural pairwise contrastive regression along with Korean NLP models
Introduction Automated Essay Scoring (AES) research has increasingly adopted deep learning and transformer-based language models. However, most prior studies have focused on English writing and pointwise score prediction, leaving the applicability of ranking-aware AES frameworks to Korean essays underexplored. Methods This study examined the applicability of Neural Pairwise Contrastive Regression (NPCR) to Korean essay scoring and compared Korean…
Impact of growth math mindset, learning goals, intrinsic motivation, and math outcomes on STEM career interest among gifted students in STEM education
Research on the determinants of students’ success in specialised STEM schools has devoted considerable attention to psychological factors. Using a path analytic model, this study investigated whether a growth math mindset, referring to the theory that math ability can be improved incrementally, is indirectly associated with academically gifted students’ math achievement and intrinsic motivation to pursue learning goals. This study also examined t…
Investigating the association of school type and gender with adolescent's mindsets
Mindset is a key factor affecting personality and learning for adolescents, especially those living in countries focusing heavily on human resources, such as Korea, Singapore, and Hong Kong. We examined associations of fixed intelligence mindset, fixed creative mindset, students' gender and school type via a structural equation modeling. The sample included 301 Korean adolescents: students in their second year at a gifted high school, general hig…
Development of a New Measure of Cognitive Ability Using Automatic Item Generation and Its Psychometric Properties
In the development of cognitive science understanding human intelligence and mind, measurement of cognitive ability has played a key role. To address the development in data scientific point of views related to cognitive neuroscience, there has been a demand of creating a measurement to capture cognition in short and repeated time periods. This paper introduces an innovative measure of cognitive ability based on automatic item generation approach…

School Principals’ Time Use for Interaction with Individual Students
To test emerging narratives of principals’ direct effect on student outcomes on a large scale, this study investigates whether school principals’ time use for interacting with individual students is associated with academic achievement and student safety at school. Built on recent research on principals’ time use, this study explores whether economic, sociocultural, and institutional features of societies influence the amount of time principals s…
An Exploration of Text Difficulty and Knowledge Support on Adolescents' Comprehension
The purpose of the study was to determine whether easy or challenging versions of texts, when accompanied by different types of instructional support, improved adolescents' reading comprehension, particularly for students with below‐average reading comprehension. The authors examined 293 ninth‐grade students' reading comprehension of 24 leveled texts over a 12‐week intervention in which teachers were randomly assigned to one of two instructional …
The mediation effect of preservice teacher attitude toward inclusion for students with autism in South Korea
Giving preservice teachers experience in working with students with autism is essential for successful teacher preparation. Structural equation modelling was employed to identify the factors affecting preservice teachers’ attitudes toward the use of inclusive settings for students with autism. The results indicated that their coursework influenced attitudes toward full inclusion both directly and indirectly, but had no effect on their perceptions…
Longitudinal Relationships between Bullying and Moral Disengagement among Adolescents
Model Selection with the Linear Mixed Model for Longitudinal Data
Model building or model selection with linear mixed models (LMMs) is complicated by the presence of both fixed effects and random effects. The fixed effects structure and random effects structure are codependent, so selection of one influences the other. Most presentations of LMM in psychology and education are based on a multilevel or hierarchical approach in which the variance-covariance matrix of the random effects is assumed to be positive de…
