This study was aimed to examine problem-solving ability of fifth graders on two types of mathematical essay problems, and to analyze the process of mathematical justification in solving the essay problems. For this purpose, a total of 14 mathematical essay problems were developed, in which half of the items were single tasks and the other half were data-provided tasks. Sixteen students with higher academic achievements in mathematics and the Korean language were chosen, and were given to solve the mathematical essay problems individually. They then were asked to justify their solution methods in groups of 4 and to reach a consensus through negotiation among group members. Students were good at understanding the given single tasks but they often revealed lack of logical thinking and representation. They also tended to use everyday language rather than mathematical language in explaining their solution processes. Some students experienced difficulty in understanding the meaning of data in the essay problems. With regard to mathematical justification, students employed more internal justification by experience or mathematical logic than external justification by authority. Given this, this paper includes implications for teachers on how they need to teach mathematics in order to foster students' logical thinking and communication.

The purpose of this study was to review the current language level of children from multi-cultural background and whether the language level of these children would be increased after participating in the 'We Start Language Intervention Program'. The subjects were 30 36-75-month old children attending daycare centers in Ansan city, South Korea. The results showed that the receptive and expressive language levels of children from multi-cultural families were low compared to those of other children, and that their expressive language level was evaluated more negatively than their receptive language level. After participating in the 'We Start Language Intervention Program', language test scores, language age and language percentile rank were all increased. It was also found that the developmental language level of multi-cultural children increased, and that of the children that had a language delay or language disorder decreased.

The purpose of this study was to determine the effects of group therapy on the language performance of aphasic patients. Four aphasic subjects participated in group therapy. Their aphasic types were TCMA (transcortical motor aphasia), conduction, anomie, and Broca's aphasia. The focus of the therapy was to stimulate cooperative learning skills. For this purpose, categorization tasks, semantic association tasks, convergent thinking, and divergent thinking tasks were employed. The results showed that all of the aphasic subjects demonstrated some improvement in writing ability, categorization ability, and speaking ability in sentences.

The present study examined the effects of preview sentences and paragraphing in expository text on subjects' recall of the text. College students who participated in this study were randomly assigned to one of four text version groups: the no preview sentences and no paragraphing group, the no preview sentences and paragraphing group, the preview sentences and no paragraphing group, and the preview sentences and no paragraphing group. The result showed no significant effects of preview sentences and paragraphing. However, students' learning ability being considered, significant interaction effects were found. Although subjects with high learning ability recalled well regardless of whether or not passage was paragraphed, subjects with low learning ability recalled more in paragraphing condition than no paragraphing condition. The implication of these results is discussed.

In this study, 197 4- to 6- year-old Korean children wereindividually tested with Concepts about Print(CAP Clay, 2000), the Picture Vocabulary Test(Kim, Jang, Lim & Bak, 1996), Korean-Wechsler Preschool and Primary Scale of Intelligence : Verbal Test (K-WPPSI), and the Basic Academy Skills Assessment : Reading(Kim, 2000). Data were analyzed by Pearson-correlation, analysis of variance, and factor analysis. There were significant differences of CAP mean scores by age. Within the subcategories of CAP, Book Orientation Concepts and Print-convention were acquired earlier than other subcategories, followed by Print-direction, Print-order and Advanced Print Concepts in that order. The scores of CAP were positively correlated with the Picture Vocabulary Test, the K-WPPSI verbal test and the reading test.

This study aims to explore the potential of Korean language learning as a means of psychological healing and improving the quality of life for Japanese middle-aged and older learners. Results showed that Korean language learning could help alleviate various psychological issues experienced by middle-aged learners and contribute to enhancing their quality of life. Learning a foreign language is not just about acquiring information but also about meeting people who use the language and understanding and experiencing their culture. In particular, for Japanese middle-aged learners, Korean language learning can be advantageous as it can lead to the discovery or development of new hobbies or interests. Results also showed that Korean language learning increased learners' opportunities for interaction with others and enjoyment of learning new cultural customs. These positive outcomes suggest the need for discussion of teaching strategies that focus on psychological healing in foreign language education. Further clinical trials with participants who learn foreign languages for healing purposes may provide more conclusive evidence on the diverse effects of language learning on stress, anxiety, depression, self-development, social connections, and cognitive ability.

Objective: This study explored the mediating effects of language development on the influences of young children's media use on positive and negative peer interactions. Methods: The data came from the 2013 Panel Study on Korean Children (N = 1,215) and were analyzed to assess the mediating effects of media use on positive and negative peer interactions, using SEM with the bootstrapping method by means of SPSS 21.0 and AMOS 20.0. Results and Conclusion: The results show that increased media use affects positive and negative peer interactions through language development. This indicates that, while media use does not directly affect positive and negative peer interactions, it appears to increase the difficulty of developing language ability; as the language development worsens, undesirable peer interactions may develop. Thus, language development seems to play an important mediating role between media use and peer interactions. Theoretical and practical implications are discussed.
