STEM Problem solving necessitates a substantial amount of specialized domain knowledge. An important element of problem-solving within the domain includes how knowledge is structured and organized in memory to facilitate efficient retrieval of relevant information and future problem solving. In previous studies, however, problem solving and…

This experimental investigation seeks to confirm and extend previous investigations that resource interdependence vs. independence during problem-solving relatively extends the problem representation phase before convergence on a solution. In this current investigation, ninth-grade Korean native language participants (n = 240) worked online to…

Although gender ideologies influence many outcomes, research shows they often fluctuate across the life course. Family structure transitions are one mechanism through which gender ideologies change. Divorced and single adults report more egalitarian ideologies than stably married adults. Little research has examined whether children in these…

Pedagogical strategies for nurturing group creativity in school mathematics have remained largely unexplored despite their significance. In this study, we explored the use of role playing in mathematical modeling activities for nurturing group creativity in a 9th-grade mathematics class in Korea. We described the theoretical bases and types of…

Adopting a cognitive perspective, this study examined roles of working memory capacity (WMC), first language (L1) syllogistic inferencing, and second language (L2) linguistic knowledge on literal and inferential understanding of L2 reading comprehension in adolescent L2 learners. Participants were 193 Korean ninth-grade learners of English. The…

Although personal and environmental correlates of adolescents' happiness have been found, the temporal direction of these relationships is less known. The present study explored the longitudinal and reciprocal relationships between self-esteem, school adjustment, and happiness during secondary school years in South Korea. Longitudinal data of…

Background: Despite extensive research examining features of adolescents' ego-identity development, little research has demonstrated patterns of ego-identity development and its relationship with various individual and environmental factors that are theoretically important for identity development. Objective: The current study investigated…

The suitability and characteristics of middle school inquiry activities in the 2015 National Curriculum of Science in Korea were studied from the perspective of eight science teachers with rich experience in teaching science inquiry activities. In-depth interviews revealed problems teachers experienced while conducting inquiry classes. Problems…

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…

The study aims to analyze student responses to chemistry constructed response items to obtain detailed information on science NAEA (National Assessment of Educational Achievement) in South Korea and to draw suggestions for enhancing curriculum, teaching, and learning. For this purpose, we analyzed 7444 answers that could be generalized as 1.29% of…

For decades, achievement goal theory has been extensively used, but empirical research still requires a clearer understanding of the underlying factors conceptualized and measured during secondary school periods. In light of the increasing use of longitudinal studies in motivation research, this study aims to investigate the longitudinal…

The declining interest in science learning, along with students' perception that science is irrelevant to their daily lives, has been identified as a significant issue. This research aimed to help students connect abstract scientific concepts with their personal and everyday experiences. To achieve this, the research utilized the metaphysical…

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,…

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…
