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.

본 연구는 예비교사가 변수와 관련된 학생의 사고를 어떻게 파악하고 대응하는지를 조사하는 것을 목적으로 하였다. 변수와 관련된 학생들의 사고를 추론하여 그에 따른 지도방안을 제시해 보게 하는 문항에서 예비교사의 주목하기와 해석하기의 특징을 동시에 살펴보았으며 주목하기와 해석하기에 따라 예비교사의 대응하기가 어떻게 제안되었는지 그 특징을 조사하였다. 예비교사 26명의 응답을 분석한 결과, 예비교사들이 학생들의 응답에서 나타나는 변수에 대한 오개념에 주목하기가 쉽지 않음을 보여주었으며, 주목은 하였으나 적절한 해석을 해내지 못한 경우를 확인할 수 있었다. 주목하지 못하고 해석하지 못한 대부분 예비교사는 변수에 대한 전반적인 이해의 부족으로 인해 적절한 대응을 제시하지 못한 것으로 나타났으며, 주목하기와 해석하기가 성공적으로 이루어졌다 하더라도 경험적 지식의 부족으로 인해 적절한 대응을 제시하지 못하였다. 연구 결과를 바탕으로, 예비교사 교육에 주는 시사점을 논의하였다.

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.

전국 8개 사범대학 과학교육계 학과 교수 70명을 대상으로 제6차 고등학교 과학과 교육과정의 적절성에 대한 인식을 설문으로 조사하였다. 대부분의 교수들은 제6차 교육과정의 '목표'와 '내용' 부분은 적절한 것으로 인식하고 있었으나, 교사의 탐구 지도 능력과 교육 여건을 고려할 때 '방법' 및 '평가' 부분은 적절하지 않다고 인식하고 있었다. 교육과정에 제시된 방법은 실행 가능성이 적고, 다루는 내용이 너무 많고, 공통과학의 경우 교과간 통합이 부족하며, 교육과정에 진술된 항목들이 포괄적이므로 구체적 지침이 필요하다고 지적하였다.

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.

초등학교 학생들의 독서능력과 수준을 고려한 독서교육을 위해 본 연구진이 선행연구로 개발한 멀티미디어 기술을 활용한 수준별 독서지원 시스템에서는 학생들의 독서능력을 진단할 수 있는 진단지, 독서능력에 알맞은 도서 및 독서방법 안내, 멀티미디어 기술을 활용한 다양한 감상표현활동 등을 개발하였다[4]. 그러나 독서교육 방법과 도서는 수준별로 제시하여 주었으나 독후활동은 수준에 관계없이 동일한 활동을 제시함으로써 수준에 알맞은 독후활동의 어려움이 제기되고 있다. 본 논문에서는 제7차 초등학교 국어과 하위목표와 교육부 ICT 기준안을 고려하여 독서에 흥미를 가질 수 있도록 학생들의 독서능력에 알맞은 멀티미디어 기술을 활용한 수준별 독후활동을 개발하고 수준별 독서교육지원시스템의 효과 검증을 하고자 하였다. 멀티미디어 기술을 활용한 수준별 독후활동은 웹상에서 안내되고 웹상에서 활동할 수 있으며, 표현 방법에 기존의 텍스트가 아닌 멀티미디어적 요소가 가미되어 학생들에게 독후활동에 대한 흥미와 관심을 높일 수 있었고 이를 통해 독서능력 향상과 자기주도적 학습력 신장에 도움을 줄 수 있었다.

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.
