An important issue for qualified science teacher education should be a proper system of pre-service education for the science teacher. There are various types of science teacher education systems in accordance with their socio-cultural backgrounds. In this paper, science teacher education systems were analysed into 3 different types: Focusing Undergraduate Certification of Education (FUCE), Open Undergraduate Certification of Education (OUCE), and Post Graduate Certification of Education (PGCE). Science teacher education systems and their outcomes, such as the quality of the science teacher, were discussed with their socio-cultural backgrounds, compared by the 3 types of science teacher education systems. For this the results of meta-analysis from TIMSS-R and OECD data sets were used. Special interests focused on countries; Japan, Korea, the United Kingdom and the United States, which would represent stereotypes of science teacher education systems and different backgrounds of oriental and western culture.

This study investigated the prospective teacher's noticing of students' mathematical thinking from the perspective of how the prospective teacher pays attention to, interprets, and responds to the student's responses related to variables. The prospective teachers were asked to infer the students' thinking from the variables related to the tasks and suggest feedback accordingly. An analysis of the responses of 26 prospective teachers showed that it was not easy for prospective teachers to pay attention to the misconception of variables and that some of them did not make proper interpretations. Most prospective teachers who did not attend and interpret were found to have failed to provide an appropriate response due to a lack of overall understanding of variables. even though prospective teachers who did proper attend and interpret were found to have failed to respond appropriately due to a lack of empirical knowledge, even with proper attention and interpretation.

BACKGROUND/OBJECTIVES: Proper nutrition intake during pregnancy and lactation is very important to both mothers and babies. Pregnant women should maintain proper nutritional status to restore decreased physical strength due to pregnancy and childbirth and produce breastmilk for the growth and development of the baby. Recently, the number of Chinese people living in Korea has increased as the exchange between Korea and China becomes active. It is important to provide proper nutrition education for pregnant women of both countries considering cultural differences. SUBJECTS/METHODS: The subjects of this study were postpartum women in Gyeonggi, South Korea and Jinhua, China. The subjects were 20-45 years old less than six months after childbirth. A survey, using self-administered questionnaires, was conducted from October 2018 to January 2019. For data analysis, 221 Korean postpartum women (KPW) and 221 Chinese postpartum women (CPW) questionnaires were used. RESULTS: KPW had significantly higher nutritional knowledge score and dietary attitude score than CPW (P < 0.001). However, overall score for dietary habits was significantly higher in CPW compared to KPW (P < 0.001). In KPW, nutritional knowledge (P < 0.01) and dietary attitude (P < 0.001) had significantly positive correlations with dietary habits. The proportions of KPW and CPW who answered that they had experience of nutrition education were 28.5% and 80.1% (P < 0.001). The score for dietary habits was lower as the hours for watching TV and using mobile phone became longer in postpartum women of both countries, with significant differences in KPW (P < 0.001) and CPW (P < 0.05). In KPW, the score for dietary habits in postpartum women with exercise experience was significantly higher than that in postpartum women without exercise experience (P < 0.001). CONCLUSIONS: More pregnancy-related nutrition education should be provided and various and effective nutrition education programs, which not only transfer information but can be practiced in the actual life, should be developed.

Objective: This study explores how pre-service teachers' knowledge changed in the field of movement education and the characteristics of the instruction they perceived during a 15-week course. Methods: The drawing of concept maps and interviews were used to discuss how pre-service teachers' knowledge changed and the characteristics of the course. Results: The results showed that the pre-service teachers interrelated concepts in a more systematic way, and the concepts they used were increased while master concepts were decreased, indicating that their knowledge changed in a far more hierarchical order after the class. Characteristics of the course that led to a change in their knowledge appeared under the proper guidance of a professor. This was well demonstrated by feedback and evaluation at the stage of planning instruction and simulation teaching. Conclusion/Implications: The study demonstrated that the proper guidance of a professor was a useful tool for fostering the professional development of pre-service teachers in regard to constructing knowledge in movement education.

We examined how the professors in the department of science education perceived the 6th high school science curriculum. A nationwide survey was administered to obtain the responses from 70 professors of 8 educational colleges. Most professors thought that the 'objectives' and the 'contents' were proper, but the 'methods' and 'evaluations' were not proper, if considered educational facilities as well as 'teachers' ability to guide inquiry. Some professors also pointed out that the 'methods' described in the curriculum did not seem to be practical, that the contents were too much for high school science courses, that the integration of the contents in the general science was not enough, and that some concrete guides were needed because the items in the curriculum were too broad.

Low-frequency geological natural disaster events such as Pohang earthquake have been occurred. As a results, there's a growing recognition on the importance of education and training for low frequency geological disasters in Korea. In spite of many years of scientific researches on volcanic disaster prevention and preparedness on Baekdusan volcano, the results do not provide the proper scenario for the training for volcanic ash event. Fall 3D volcanic ash diffusion model was run based on wind field data for the last five year, assuming Aso Mountain's explosion with volcanic explosion index 5 for seventy two hours. The management criteria values for proper actions in the previous studies were applied to make a scenario for thirteen groups of the disaster response teams such as train transportation, water supply, electrical facilities and human health. The models on the relationship between education and training for disaster prevention and response were suggested to fulfill the scientific and practical training at local level.

In this study, we investigate integrated educations as an alternative educational method. I look around the developments of the integrated educations from MST education through STEAM education, especially in mathematics education. I analyzed integrated educations such as MST, STS, STEM, STEAM educations and compare them to each other, in mathematics education. And I discuss how to apply STEAM education to Korean mathematics education. I suggest a proper integrated education, in particular, STEAM education, as one that is suitable for Korean mathematics education.

Our research team has developed diagnosis papers which diagnose reading ability of students, reading materials and guidance of reading method which are proper for reading ability and various appreciation expression activities in the leveled reading supporting system applying the multimedia techniques, which is developed as a previous research for reading education that considers the reading ability and level of elementary school students. However some difficulties have been raised in activities after reading proper for level because we suggested them all the same regardless of level though we proposed the reading methods and reading materials by level, We tried to develop the leveled activities post-reading applying multimedia techniques which are proper for reading ability of students and exam the effects of leveled reading supporting system considering the subordinate goal of 7th Korean curriculum of elementary school and the ICT standard of the Education Ministry on this thesis for promoting an interest in reading of students. The leveled activities after reading which are applying multimedia techniques could be guided and applied on the web, and helped develop the reading ability and self-leading learning ability by raising the interest and concern of students in the activities after reading because the multimedia elements, instead of existing text, were added to the expression.

The purpose of this study was to investigate culinary arts and hospitality students' food safety practice behaviors, intentions, attitudes, and barriers to food safety compliance. This descriptive study used the self-report questionnaire. The convenience sample was composed of 266 college students majoring in culinary arts and hospitality. The students indicated that they never or rarely use a thermometer to determine if meats have been adequately cooked. Examples of positive food handling behaviors were hand washing, sanitation of fruits and vegetables, discarding of food past its expiration date, counter top sanitation, and proper food storage. Students strongly agreed it is their responsibility to practice food safety and to educate their employees about food safety. The primary barrier to proper food safety as ranked by student respondents is the misunderstanding about food labeling. Previous food safety education and internship experience appeared to improve the student respondents' perceived attitudes toward following the principles of food safety practices (p < 0.05), although behaviors and intentions to use the correct food safety practices were not affected. The findings of this study suggest that programs should consider integrating information and experiential learning opportunities in their courses that would be enhance student understanding about food safety. The outcomes of this study can be applied to develop food safety education materials and programs for culinary arts and hospitality students.
