  • The purpose of this study was to evaluate the physicochemical components and antioxidant activities of wheat sprout powder prepared by the enzymatic hydrolysis and lactic acid bacteria treatment. The four kinds of pre-treatment were: no treatment (WP), treated with enzyme (WPE), treated with lactic acid bacteria (WPL), and treated with enzyme and lactic acid bacteria (WPEL) were applied to the wheat sprout powder. The WPEL had higher total free amino acid and essential amino acid content than the other samples. As for the volatile aroma of the wheat sprout powder, 29 types of compounds were identified in the WP and WPL, 28 types in the WPE, and 27 types in the WPEL, respectively. The total polyphenols and flavonoids contents, in the wheat sprout powder was enhanced with the enzyme and the lactic acid bacteria pre-treatment. The WPEL had highest DPPH radical scavenging activities. The overall acceptability was the highest at 6.24 points in the WPEL. Based on these observations, it was confirmed that the enzyme and lactic acid bacteria pre-treatment could improve the antioxidant activities and active component of the wheat sprout powder.

  • This study aimed at exploring how an instructor constructs meanings through content-based instruction (CBI) offered to pre-service teachers majoring in early childhood education. The course, early childhood mathematics education, was conducted during the spring semester in 2011. This study adopted a narrative inquiry, and data were collected through observations, interviews, and work samples. This study found that during the whole process from the preparation phase to the end-of-program evaluation, the instructor captured diverse challenging moments. During the preparation phase, she needed to have careful orchestration in designing lessons in order to overcome her feeling of pressure as a non-native speaker of English and design the integration of contents and English language learning to be truly powerful. In the phase of implementation, the lack of student motivation and building a good rapport between the instructor and the students were certainly challenges. The result of the student evaluations weakened her desire to implement CBI. The instructor incorporated diverse instructional strategies to overcome the obstacles. The instructor's experiences in this study will positively shape future educators' thinking and learning about meaningful and appropriate academic English instruction for content-area teaching of college students who were majoring in early childhood education.

  • Korean uses a dual numeral system consisting of native and Chinese words. This dual numerical system is customarily selected in real life, mixed with two methods, or irregularly transformed. Therefore, the burden on both students and teachers is increased in the learning guidance process of numeral. This study recognized the need to improve the difficulty of learning guidance due to the dual numeral system. To this end, the context in which the numeral system method is selected, various modified cases, and related guidance contents of the current curriculum and textbooks were analyzed and organized. As a result of the analysis, there were characteristics of the selection and deformation of the numeral system method, which appears according to the actual situation using numerical. However, the criteria for characteristics were ambiguous and there were no specific guidance guidelines in the curriculum and textbooks. In this case, since the role of the teacher is more important, the teacher should be aware of the detailed characteristics of the actual situation related to the dual numeral system and let the student understand through experience and practice on various aspects of the use of the dual numeral system.

  • Dongje school (同濟學校), alternately Dongje medical school, is generally recognized as the first modern school for Korean medicine. However, there is very limited information concerning its establishment, duration period, governance, location, and contents for teaching. We found several points which are different from popular opinions through investigating news articles of those days and maps. Dongje school has established on June 1, 1906 and the time of its discontinuance is not clear. The school was founded with the cooperation of three former government officials of the Korean Empire, Eungse Lee (李應世), Piljoo Kang (姜弼周), and Dongho Cho (趙東浩) and many people donated fund for supporting Dongje school. However, there is no evidence of national or royal expenditures for operating the school. Dongje school has been established in 76-6, Seohak hill (西學峴), Yeogyeong-bang (餘慶坊), West county (西署), Seoul and moved to Naesum-si (內贍寺) located in Bongsangsi front village (奉常寺前門洞), Indal-bang (仁達坊), West county, at September 1906. The curriculum of the school comprehends several disciplines including literature in Korean and Chinese, mathematics, foreign language, physics, and Western medicine, as well as Korean medicine. Particularly at that time, they thought both of women and men. To elucidate the issue of the governance of Dongje school regarding the national or royal establishment, more information and extensive studies should be needed.

  • This study aimed to analyze the changes in the physics curriculum of elementary schools over the past years and to discuss the issues faced by the science curriculum for elementary education prior to the next curriculum revision. We analyzed changes in the elements of the contents from the 7th curriculum to the 2015 revised curriculum and reviewed studies conducted after the revision in 2015. Additionally, three professors majoring in physics education discussed the results of the curriculum analysis. The result indicates that content of the physics curriculum for elementary education was generally reduced after the 7th curriculum. Specifically, difficult concepts were omitted or designated to a higher school level. Concerns related to the science curriculum pertain to the content adequacy and difficulty of the current curriculum, its relationship with mathematics, connection between the Nuri curriculum and the integrated curriculum for the 1st and 2nd grades, and the achievement standard predicate problem.

  • Recently, as the educational paradigm shifts from teacher-centered to learner-centered, the active construction of knowledge of learners is becoming more important. Accordingly, classes using mathematical modeling are receiving attention. However, existing research is focused on teachers or middle and high school students, so it is difficult to apply the contents and results of the research to preservice teachers. Therefore, in this study, the experience of mathematical modeling was examined for elementary school preservice teachers. And we looked at how positive experiences of mathematical modeling change their perceptions. As a result of the study, elementary school preservice teachers had very little experience in mathematical modeling during their school days. In addition, it was found that the perceptions changed more positively than when a theoretical class on mathematical modeling was conducted, rather than when the experience of mathematical modeling was actually shared. Based on the results of this study, implications were suggested in the course of training preservice teachers.
