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…

IEA's International Computer and Information Literacy Study (ICILS) 2018 is designed to assess how well students are prepared for study, work, and life in a digital world. The study measures international differences in students' computer and information literacy (CIL): their ability to use computers to investigate, create, participate, and…

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…

This study analyzed the responses of Korean students to interest, confidence, value, and instructional clarity in science and mathematics. To achieve this, the raw data of the recent student survey of TIMSS were analyzed. A one-way ANOVA was performed, and a post hoc test was performed. Additionally, a cohort analysis was performed to determine…

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…

In the literature, response style is one of the factors causing an achievement-attitude paradox and threatens the validity of the results obtained from studies. In this regard, the aim of this study is two-fold. Firstly, it attempts to determine which item response tree (IRTree) models based on the generalized linear mixed model (GLMM) approach…

The current study applied an opportunity perspective and an individual trait approach to explain the link between bullying perpetration and victimization among early adolescents in South Korea. This study addressed direct effects of low self-control and lifestyle factors on bullying victimization as well as mediating effects of lifestyles on the…

This study examines L2 fluency in speaking interactions based on the number and type of utterances. The participants were 25 Korean eighth-grade learners of English as a foreign language. They performed five communicative tasks in groups, and their speaking interactions were audio-recorded and analyzed to measure the frequencies of sentence-level…

In this study, we examined students' epistemological and positional framing during small group scientific modeling to explore their context-dependent perceptions about knowledge, themselves, and others. We focused on two small groups of Korean eighth-grade students who participated in six modeling activities about excretion. The two groups were…

The International Association for the Evaluation of Educational Achievement's (IEA) mission is to enhance knowledge about education systems worldwide, and to provide high-quality data that will support education reform and lead to better teaching and learning in schools. In pursuit of this aim, it conducts, and reports on, major studies of student…

Student learning is increasingly taking place in digital environments both within and outside schooling contexts. Educational assessments are following suit, both to take advantage of the conveniences and opportunities that digital environments provide as well as to reflect the mediums of learning increasingly taking place in societies around the…

Identifying key determinants of success plays an important role in efforts of assessing the current state of educational practices and implementing effective actions to improve academic performance. Given how important is accurate identification of these determinants for valid comparisons, the aim of this research was to present extensive…

Trends in International Mathematics and Science Study (TIMSS) is an international comparative study that has been implemented by the International Association for the Evaluation of Educational Achievement (IEA) since 1995. This proposed study is aimed to identify the affective factors contributing to eighth graders' science achievement in TIMSS…

In this article, we discuss the benefits of Bayesian statistics and how to utilize them in studies of moral education. To demonstrate concrete examples of the applications of Bayesian statistics to studies of moral education, we reanalyzed two data sets previously collected: one small data set collected from a moral educational intervention…

This paper examines what affects adolescents' English anxiety in the English as Foreign Langauage (EFL) context. A total of 414 adolescents in South Korea participated in the study and the AMOS 20.0 was used in structural equation modeling for statistical analysis. The results are as follows. Girls showed a higher level of English anxiety and…
