This study examined influences of teacher's transformational leadership, and their trust and empathic understanding on children's learning motivation. Participants were 513 $5^{th}$ and $6^{th}$ graders from Seoul, Buchon and Inchon. Data were collected via questionnaires and analyzed by descriptive statistics, Pearson's correlation, and multiple regression analysis. Results showed that (1) Teacher's transformational leadership, trust and empathic understanding were positively related to children's learning motivation. (2) Teacher's transformational leadership was the strongest predictor for children's learning motivation. (3) Teacher's transformational leadership had a direct influence on children's learning motivation empathic understanding mediated between teacher's transformational leadership and children's learning motivation.

The study aims to figure out pre-service elementary teachers' knowledge understanding on 'stratum and rock' as well as teaching-learning types on the same topic. A total of 65 seniors in an advanced science education course at B University of Education joined the research to fulfill the purpose above. With PCK classification framework, the study examined pre-service teachers' knowledge understanding on 'stratum and rock' while it analyzed how the teachers would teach the given topic to students. The results of the study are presented as follows. First, it was observed that the pre-service elementary teachers have a great understanding on 'stratum and rock' that would be taught via a science textbook for elementary fourth graders. However, regarding terms in 'shale and limestone', they appeared to have a relatively short understanding. Second, PCK elements of the pre-service teachers related to 'stratum and rock' were analyzed and according to the results, the teachers would be interested in teaching model selecting in the teaching-learning strategy field while they would be well aware of how important it is for them to perform an experiment in a teaching process. The teachers also appeared to understand that the teacher question can be mutual complementary during class. However, it turned out that the teachers would have a very much low understanding on learners' prior knowledge as they particularly believe that learning could be significantly affected by the learners' perception level as well as their learning interest and motive. Third, the pre-service elementary teachers were told to design teaching plans on 'stratum and rock' so that the study could find out what learning-teaching methods the teachers would adopt to teach the topic. It was learned that the teachers would proceed with the class basically by giving the learners a descriptive explanation on the topic and also by using pictures and drawings to enhance the learners' understanding during the class.

이 연구는 중학생들의 과학 지식의 본성에 대한 이해와 개념 이해 및 학습 젼략 사이의 관계를 조사하였다. 인천 지역의 중학교 1학년 162명을 대상으로 과학 지식의 본성 검사와 학습 전략 검사를 실시하였다. 밀도에 대한 컴퓨터 보조 수업 후 개념 검사를 실시했다. 연구 결과, 학생들의 개념 이해와 심층적 및 피상적 학습 전략은 과학 지식의 본성에 대한 이해와 유의미한 상관이 있었다. 학생들의 복합적인 학습 전략의 유형을 확인하기 위해 군집분석을 실시하였다. 그 결과, '심층적 전략 점수는 높고, 피상적 전략 점수는 낮은 집단(군집 1)', '심층적 전략 점수는 낮고, 피상적 전략 점수는 높은 집단(군집 2)', '심층적, 피상적 전략 점수가 모두 높은 집단(군집 3)'으로 구분 되었다. 일원 변량 분석 결과, 과학 지식의 본성 검사와 개념 검사 모두에서 군집 3의 점수가 다른 군집들 보다 유의미하게 높았다. 또한 개념 검사에서는 군집1이 군집2에 비해 보다 높은 성적을 보였다. 이에 대한 교육학적 함의를 논의하였다.

이 연구에서는 과학학습에 대한 동기적 신념과 자기주도 학습능력을 각각 과학 개념 이해에 영향을 줄 수 있는 구인으로 가정하고, 이들의 관계를 정량적으로 탐색하고자 하였다. 이를 위해서 이 연구에서는 중학생들을 대상으로 과학학습에 대한 동기적 신념과 자기주도 학습능력, 물질 변화에 대한 개념 이해에 대해 기존 연구의 측정도구를 이용하여 각각 조사하고, 조사한 응답 분포를 바탕으로 이 세 변인 간의 인과 관계를 PLS 구조방정식모형을 통하여 분석하였다. 연구 결과, 이 연구에서 설정한 잠재변수인 과학학습에 대한 동기적 신념, 자기주도 학습능력, 물질 변화 개념 이해의 측정은 신뢰도와 타당도 면에서 통계적으로 적합한 것으로 나타났다. 또한, 잠재변수들 간의 인과 관계를 분석한 결과, 자기주도 학습능력은 동기적 신념과 물질 변화 개념 이해에 모두 영향을 미치지만, 동기적 신념은 자기 주도 학습능력에만 영향을 미치고 물질 변화 개념 이해에는 영향을 미치지 않았다. 이 연구를 통하여 과학학습 상황에서 자기주도 학습 능력만이 과학 개념 이해에 직접 영향을 미치며 동기적 신념은 간접적으로만 영향을 미친다는 것을 확인할 수 있었다. 이 연구는 과학학습 과정에 관여하는 변인들 간의 인과적 관계를 정량적인 방법을 통해서 확인했다는 점과 과학교육 연구 분야에서 PLS 구조방정식모형을 새로운 연구방법론으로써 제안한다는 점에서 의의가 있다.

The purpose of this study is to develope education for sustainable development of understanding programme. The results of this study are as follows. Firstly, this programme is intended to enhance an university student's basic understanding, core skills and viewpoint of sustainable development. Secondly, the programme contains 10 modules, organised in four thematic sections. Each module is made up of two or three activities that are supposed to encourage adult learners in their mature understanding of sustainable development. Thirdly, there are three key teaching-learning strategies such as a case study, story telling and project study. These teaching-learning methods play a key role in the learning process. In conclusion, it is expected to indicate the goal and the value of the sustainable development clearly, and to provide the related information and knowledge constantly and systematically in the learning for sustainable development. Thus, it would be possible to enhance learner's awareness and attitudes towards sustainable development.

Artificial intelligence and machine learning are used in many parts of our daily lives, but the basic processes and concepts are barely exposed to most people. Understanding these basic concepts is becoming increasingly important as kids don't have the opportunity to explore AI processes and improve their understanding of basic machine learning concepts and their essential components. Machine learning educational tools can help children easily understand artificial intelligence and machine learning. In this paper, we examine machine learning education tools and compare their features.

Artificial intelligence has been applied to many industries, including medicine. Among the various techniques in artificial intelligence, deep learning has attained the highest popularity in medical imaging in recent years. Many articles on deep learning have been published in radiologic journals. However, radiologists may have difficulty in understanding and interpreting these studies because the study methods of deep learning differ from those of traditional radiology. This review article aims to explain the concepts and terms that are frequently used in deep learning radiology articles, facilitating general radiologists' understanding.

Promoting students' mathematics understanding is an important research theme in mathematics education. According to general theories of learning, mathematics understanding is close to active learning or significant learning. Thus, if a teacher wants to promote his/her students' mathematics understanding, he/she should pay attention to the students so that the students' thinking is in active situation. In the first part of this paper, some mathematics teachers' ideas about paying attention to their students in Chinese high school are given by questionnaire and interview. In the second part of this paper, we give some teaching episodes about how experienced mathematics teachers promote their students' mathematics understanding based on paying attention on them.

Many believe that electronic distance teaming education transform higher education, saving money and improving learning qualify So, the open University, which teaches around 280,000 students at a distance, is examining the adaption of its distance teaching methods for the internet. But, there are only one type of distance learning education of one way direction. To understand all of a student which selected some of e teaming course, teacher must check that how many student to understand and what is the difficult problems. Without checking this condition, It will be a very difficult and boring distance learning course. In this paper, we introduce of intelligent learning contents of full duplex direction that teach understanding student and not understanding student. The computer simulation results confirms that full duplex e learning system has been proven to be much more efficient than one way direction which not considering about understanding problems.
