  • The Category Fluency Test (CFT) is a widely used verbal fluency test. The standard measure of scoring the test is the number of distinct words that a subject generates during the test. Recently, other measures have also been proposed to evaluate performance, such as clustering and switching. In this study, we examine clusters and switches can be assessed using word similarity measures. Based on these measures, we can distinguish between subject groups.

  • The purpose of study suggest that new strategies available for the physical therapy curriculum development are trying to elicit from world-renowned universities those to keep pace with the globalization. The curriculum of 3 universities in Australia was compared with those of a four-year course in Korea. The 3 university are Sydney, Melbourne and Queensland Universities in Australia. Overall, the curriculum in Korea not only showed overlapping subjects, a shortage of clinical time and foundation science but, didn't deal with many subject to satisfy international recommendation. We suggest that a new curriculum should be based on the three parts which are foundation, essential divided into 6 areas and selection subject, particularly extended clinical experience to essentially need to be physical therapy in the world-standard.

  • We investigated the characteristics of lesson session and the professional development of teachers who conduct good teaching science subject. Seven teachers' were selected the finalists at the elementary school science and teaching competition. The study was based on a semi-structured questionnaire and interviews. To prove validity of the study, the collected data were verified by subject teachers for feedback. The results showed that the teachers believed that their lesson contents and methods were superior to other teachers. To enhance professional development in their lessons, they are only being made through help from colleagues and personal efforts, and a systematic development was involved with necessary situation. As a plan for enhancing an effective quality enhancement of lessons, open classes and conversation between colleagues were proposed. An organization or a group that can motivate teachers and provide systematic support for quality enhancement of lessons by teachers is needed.

  • The purpose of this study is to measure the extent of collaboration by comparing team size patterns of Korean LIS journals with international LIS journals. For the sample dataset, the top 30 ranked international journals in the field of LIS were selected using the Scimago Journal Rank (SJR), and 4 Korean LIS journals were selected for the years between 2010-2016. The size of the team who authored Korean journal articles were collected from the RISS database, while the size of team who authored international journal articles from the top LIS journals were collected using the Scopus database. The result of this study shows that the most common team size ranged from one member team to three member teams. Overall, the collaborative team size in international journals was higher than Korean journals. In particular, one member team was the most common team size in Korean journals, whereas two members team was most common in the international journals. At the subject level, the most common team size was one team member in the subject area of Library Related, while the most common team size was three team members in the subject area of Science/Engineering. The result of this study suggests that within LIS, the size of teams may vary considerably due to differences in subject areas.

  • The purpose of this study was to investigate the suitability of elective of the 2009 revised high school science curriculum. This study surveyed 911 students in 126 high schools by using proportionate stratified sampling. Each participating students carried out the on-line survey comprising 13 items about personal and academic suitability. The result of analyzing the response of the questionnaire were as follows. First, there were deviation of study-load, depth, difficulty, etc. between science elective I and II. Second, even though 'science' subject was developed as a subject for improving scientific literacy, it was found that it was considered difficult next to Physics I. Besides, it showed 'science' subject could not function properly to improve the ability to communicate. According to the results of analyzing the degree of interest in science elective, it can not be determined 'no interest in subject' is from the reason of difficulty or large amount of contents to memorize. The results of this study will be useful to provide suggestions for the improvement of next high school science curriculum and textbooks.

  • For decades, reflection has been recognised as a meaningful tool to bring forth teachers' ownership as well as knowledge and action empowerment in teacher education. Yet there have been few studies on elementary teachers' reflection on their science teaching in Korea. In this study, 71 reflective journals of 24 elementary teachers on their science teaching were analyzed. The characteristics of reflective journals were analyzed in terms of 'productive reflection', a concept suggested by Davis (2006). Unproductive reflection is mainly descriptive without analysis, whereas productive reflection can promote teachers' learning by integrating four aspects of teaching (learner/learning, subject matter knowledge, instruction and assessment). The result showed what elementary teachers consider and emphasize and how they integrate their ideas. Most of reflective journals included aspects of 'instruction', 'learner/learning', and 'subject matter knowledge'. However 'instruction' was emphasized most frequently (69.0%) than 'subject matter knowledge' (33.8%) and 'learner/learning' (26.8%). 'Assessment' was hardly included nor emphasized. More than half of the journals (56.3%) showed no integrations, which were unproductive reflection. A third of the journals (32.4%) integrated only two aspects among four. Average score of integrations was 1.6 on a scale of 4 points. The integrations were not affected by the length of reflective journals and the teaching experience. These findings suggest that productive reflection would not increase naturally with teaching experience and there needs more tactful guidance to develop elementary teachers' productive reflection on their science teaching.

  • Objective : The purpose of this study was to identify the characteristics of a single-subject research study and qualitative levels in which occupational therapy interventions were performed on children with cerebral palsy. Methods : This study targeted papers, published in Research Information Sharing Service (RISS), National Digital Science Library (NDSL), Koreanstudies Information Service System (KISS), and E-article from May 20 to 29, 2022. The search terms were 'cerebral palsy' AND 'single subject research design' OR 'individual subject study'. Eleven papers, were finally selected and analyzed. Results : Most of the studies were medium in methodological quality, and the subjects were pre-school age and spastic hemiplegia. Among the single-subject designs, intervention-removal designs were the most common, and among them, ABA designs were the most common. Interventions included assistive devices, constraint-induced therapy, neurodevelopmental therapy, and sensory integration therapy were 2, and upper extremity exercise, interactive metronome, and CO-OP were 1. Dependent variables were measured with 2 to 4 measurement tools, Significant improvements were found in postural control ability, gait and balance, hand function, and upper extremity function. Conclusion : This study confirmed that it is helpful to apply cerebral palsy occupational therapy by presenting the characteristics of cerebral palsy, intervention sessions and effects, measurement tools and methodological quality levels.

  • Research into scientific inquiry methods indicates that providing various types of inquiry methods can enhance students' science loaming in terms of providing students with actual science in various ways' more so than exposure to one type of inquiry method. This article develops a framework for an analysis of scientific inquiry types based on the nature of scientific enterprise. We selected three types of scientific inquiry: these were minds-on activities, hands-on activities, and experimenting. Elementary science textbooks in the 7th national science curriculum were analysed according to the following subject areas; earth science, physics, biology, and chemistry. A total of 61 teaching units from 3rd through 6th grade science textbooks were investigated. The frequencies of each type of scientific inquiry method were slightly different among four science subject areas. The most frequent type which appeared in physics and chemistry was the hands-on type, while the minds-on activity type was the most frequent type which appeared in earth science and biology.
