수학적 추론에 대한 예비교사의 이해 및 지도 능력 증진 방안
김선희,김수민 이화여자대학교 교과교육연구소 2019 교과교육학연구 Vol.23 No.1
In order to improve students' mathematical reasoning ability, many countries including Korea are making efforts to nurture the competence. However, no sufficient researches have been conducted on how preservice teachers, who are going to teach mathematical reasoning, understand this and which teaching capacity they should develop. Based on the consideration, this study prepared a questionnaire for preservice teachers to see what kind of mathematical reasoning knowledge they need, and provided a variety of experiences that could enhance pedagogical knowledge for preservice teachers. To see it from the students' point of view, they were asked to analyze the types of reasoning utilized in solving math problems, and from the teacher's point of view, they were asked to design, practice and evaluate math classes applied with the reasoning. The results showed that the preservice teachers have improved their understanding of mathematical reasoning through various experiences and demonstrated a positive change in their ability to teach mathematical reasoning. 학생들의 수학적 사고 능력을 향상시키기 위해 우리나라를 비롯한 많은 국가들이 수학적 추론 능력 함양에 많은 노력을 기울이고 있다. 그러나 훗날 학생들에게 수학적 추론을 가르쳐야 하는 예비 교사들이 이에 대해 얼마나 이해하고 있는지, 어떤 지도 능력을 갖추어야 하는지에 대한 연구는 미비하다. 본 연구는 예비교사들에게 필요한 수학적 추론 지식이 무엇인지를 살펴 이를 예비 교사들에게 제공하고 사전·사후의 절차로 답하게 하였다. 예비교사들에게 수학적 추론에 대한 교수학적 지식을 키울 수 있는 다양한 경험을 학생 입장에서, 교사 입장에서 제공하였다. 학생 입장에서는 수학 문제를 해결한 후 활용된 추론이 무엇인지 분석하게 하였고, 교사 입장에서는 학생 활동지 과제를 분석하고 추론을 반영한 수학 수업을 설계하고 시연하고 평가하게 하였다. 그 결과, 예비교사들은 수학적 추론에 대한 이해가 증진되었고, 수학적 추론을 지도하는 능력에 있어 긍정적인 변화를 보였다.
토양 pH와 온도 조건이 농업용 항생제 옥솔린산의 생물학적 분해에 미치는 영향

Biodegradation of antibiotics in soil can be affected by various environmental factors. This study was set to in-vestigate the effect of environmental conditions such as soil pH and temperature on the degradation of oxolinic acid (OA), one of the agricultural antibiotics used in South Korea, in soil. Rice paddy soil (RS) and field soil (FS) were contaminated with OA and the soil pH was adjusted to 5.7±0.2, 6.8±0.2, and 7.6±0.1. The soil samples were kept at different temperatures (2.3±0.2, 23.0±0.6, 30.5± 0.3℃) for 30 d. The changes in the OA concentrations were determined at selected times. With the RS and FS, the OA removal was not affected by the soil pH used in this study; however, at pH 7.6, the OA removal in the RS was greater than that in the FS, which can be attributed to the different soil properties. The OA removal was similar at 23.0 and 30.5℃ in both soils, but was lower at 2.3℃. The information on the effect of different environmental con-ditions on the degradation of antibiotics in soil is very limited. Therefore, further studies are needed to better manage the residual antibiotics in the agricultural envi- ronment. .
대학 교양수업에서의 일본문화 관심도 경향분석 및 교육방안 모색

The purpose of this study is to analyze objective data of interest in Japan, reveal its trend, and seek the direction of education through a survey on the frequency of expression of associated words related to society and culture in Japan. In fact, the emphasis on culture in university language education is due to the globalization and information age and the reorganization of curriculum, and this is why the number of lectures on social culture in universities is increasing. The need for cultural education, which was neglected in language education in the past, has been emphasized, but it is undeniable that it is a transitional situation that is recognized as a basic knowledge to develop language skills. Through the observation of the frequency of expression of culture-related words in this study, it can be recognized that university students are interested in Japanese society and culture in various fields. In general, other cultures were mainly delivered in the form of knowledge through media, newspapers, books, and magazines, but in the recent information age, a large amount of cultural items are delivered quickly and directly through various media such as the Internet. In addition, the spread of the Internet, YouTube, and SNS has led individuals to actively and selectively interact with and learn about culture at their own discretion.In addition, the number of ways to travel in person and experience socializing is increasing. Through this study, it can be assumed that the direction of cultural education should be changed, as there are perception gap of culture between generations, individual experiences and education, and the utilization of media, etc. In future university education, various IT technologies such as virtual reality space (Metaverse) should be combined to provide Japanese culture education through SHEEF experiences.
SNS소통법을 활용한 일본사회이해의 강의 개선 방안 연구 -패들렛과 멘티미터를 중심으로-

未来社会の急変する状況の中で、予測不可能な複雑な問題について柔軟かつ創意的に解決していき、他の分野と融合した思考の枠組みの中で分析できる能力を兼ね備えた人材養成が教育の中心課題となった。 教育の変化において、教授者と学生間、学生と学生間の疎通および相互作用が重要視されており、これにはデジタル時代に適した多様な疎通ツールを使用してグローバル化の中の地域間疎通だけでなく世代間疎通、協業が可能になるようにすることは何より重要になった。教育現場でフリップラーニングは新しい教育方式で試みられ、これは伝統的な画一的で一方向的な知識伝達方式の教授中心の授業ではなく、学習者が中心となる教育、双方向相互作用という方式の教授法で新しい大学の教育モデルとして強調されてきている。 本研究では、COVID-19時代を経験しながら教育現場の変化を図り、新しいコミュニケーション方式を導入することで、未来社会が要求する自律的で創意的な人材養成を目標とする講義改善案を提案する。授業進行は次のように5段階に分け、SNS疎通ツールとしてグーグル、パドレット、メンティメータを活用する。 1.Preclass (1)教授者のテーマ提示、質問、学生たちの考えを探り出す (2)生徒たちの各自の意見表現、他人の意見理解、比較、情報拡張、自分の考え検討、生徒間の討議 2.Inclass (3)教授者の提示された内容に対する傾向把握、分析、講義による知識習得、深化学習 (4)学生たちの意見調整、討論、考え方整理 3.Postclass (5)体系的な内容の整理、クイズで理解度を確認する。 すなわち、授業前の導入部で学生たちに質問で思考を刺激し、創意的な考えを拡張し、スキーマを活性化する。 教授の講義を通じて深層学習が行われ、内容を整理する。この時、最も重要な部分は学生は自分の考えを表現し、他人との考えを比較し、討議を通じて考えの整え、最後に内容を熟知して完成していく順である。
