Although competent argumentative writing is important for academic success and daily life, it is difficult to teach, especially in middle schools where English is taught as a foreign language (EFL). Previous research has indicated that extensive reading or writing improves the descriptive writing skills of EFL students. However, it is not certain…

Research has demonstrated the crucial role of creative metacognition and risk-taking in creativity. However, little empirical research has examined how creative metacognition and risk-taking work on creative performance in educational practice. This paper explored the moderating effects of creative metacognition on the relationships between…

We investigated the transmission of utility value from teachers to students by testing a model based on modern expectancy-value theory and empirical evidence for value transmission. A sample of 219 Korean 8th graders responded to surveys regarding the subject of history and their history teacher. Structural equation modelling showed that students'…

In the present study, we illuminate students' multiplicative reasoning in the context of their units-coordinating activity. Of particular interest is to investigate students' use of three levels of units as given material for problem-solving activity, which we regard as supporting a more advanced level of multiplicative reasoning. Among 13 middle…

East Asian students have consistently performed well in mathematics compared to their international peers. Though many researchers have attempted to explore the factors that underpin their success, most studies have focused only on a limited set of variables. Mathematics achievement, however, is a complex phenomenon, determined by multiple…

Mathematics growth trajectory plays a significant role to predict future outcomes and careers. We examined the existence of different growth trajectories in mathematics during the late elementary-school period (from Grades 4 to 6) and the relationship between the trajectory group classification and later mathematics achievement (Grade 8). Then,…

A hotly debated topic is the effectiveness of inquiry-based instructional practice in science classrooms on student achievement and motivation. Numerous studies based on multinational large-scale education data show such student-centered instructional practice positively led to students' motivational beliefs but was negatively associated with…

The purpose of this study was to examine middle school students' gestures during a geological field trip. Previous research on gestures has focused on understanding human development and exploring students' gestures can be helpful in improving understanding of students' communication in learning environments. In this study, middle school students…

There has been increasing interest in exploring heterogeneous treatment effects using machine learning (ML) methods such as causal forests, Bayesian additive regression trees, and targeted maximum likelihood estimation. However, there is little work on applying these methods to estimate treatment effects in latent classes defined by…

The purpose of the current study was to examine how perceived parental bonding indirectly affects bullying perpetration through adolescent psycho-emotional states. Using structural equation modeling, the authors tested a comprehensive model, wherein lack of parental caring was associated with increased adolescent anxiety and suppressed anger,…

One distinguishing feature in terms of national curriculum revisions is the emphasis on invention education in the subject of technology. This study investigates how South Korean middle school students perceive inventors. A manufactured tool for testing and a checklist for evaluating images of inventors were created to assess drawings of 115 8th…

Cyber delinquency in adolescence is a particular area of concern for psychologists owing to its association with several mental health issues and its potential link with offline delinquency. This longitudinal study examined the stability of changes and directions of influence in adolescents' cyber delinquency, aggression, and offline delinquency…

This article investigated how mathematic anxiety (MA) of Korean middle school students could be reduced by comparing analytically their cognitive neuroscience and questionnaire results. We developed a three-hour Complex Treatment Program (CTP) on quadratic functions for the study. In the summer of 2016, we collected data of the pre and post MA…

Language learning is context-dependent and requires learners to employ different sets of language skills to fulfill various tasks. Yet standardized English as a foreign language assessments tend to conceptualize English proficiency as a unidimensional construct. In order to distinguish English proficiency as separate context-driven constructs, I…

The purposes of our study were to develop and validate a test for measuring Korean elementary and middle school students' information and communications technology (ICT) literacy and to make suggestions for improving ICT literacy across Republic of Korea. To those ends, we conducted a literature review, consulted expert opinions, administered a…
