Despite the significance of teacher guidebooks as a support for teacher learning, there are few studies that address the educative features of teacher guidebooks. The purpose of this study is to develop a framework for analyzing the educative features of teacher guidebooks for elementary school mathematics. The framework developed by Fuentes and Ma(2018) for analyzing teacher guidebooks, "Teacher Learning Opportunities in Mathematics Curriculum Materials", was used as an initial framework by adding the unit development flow that reflects on the organizational features of teacher guidebooks in Korea for elementary mathematics. Then, the framework was modified and supplemented by testing 10 types of teacher guidebooks for Grades 3 and 4 per six units reflecting on different mathematical strands. As a result, the final framework expanded the initial framework and added elements related to each dimension of the framework according to the unit development flow. The analytical framework developed in this study can be used to closely analyze the educative features of teacher guidebooks of Korean elementary school mathematics in the future and to develop teacher guidebooks to promote teacher learning.

This study is to figure out the activity of individual education with the note-taking in math class and correction and supportive explanations on attitudes toward learning of underachievers in mathematics in the second-year class of high school. This study has begun on the basis of the judgement that the note-taking especially correction and supportive explanations could help the underachievers in mathematics focus in class and develop good learning habits, and besides, students make a good relationship with teacher. According to this result, Many researches and exertions need to inform every student that mathematics is open and doing mathematics is a happy object. if the students who are underachievers were given the chance to organize their learning by themselves in the class with note-taking and correction and supportive explanations in the long-term, it should be effective enough to change their attitudes toward learning.

The purpose of this study was to examine the mathematical components of word problems and the structure of the components, to examine the characteristics of the understanding of mathematics high achievers about word problems, and ultimately to devise a teaching method geared toward facilitating learner understanding of the word problems. Given the findings of the study, the following conclusion was reached: First, word problems could be categorized according to their mathematical components, namely the mathematical structure of multiple variables provided to learners for their problem solving. And learner's reaction might hinge on the type of word problems. Second, the mathematics high achievers relied on diverse strategies to understand the mathematical components of word problems to solve the problems. The use of diverse strategies made it possible for them to succeed in problem solving. Third, identifying the characteristics of the understanding of the mathematics high achievers about word problems made it possible to layout successful lesson plans that stressed understanding of the mathematical structure of word problems. And the teaching plans enabled the learners to get a better understanding of the given word problems.

The purpose of this study were to explore teaching method for scientific inquiry including scientific argumentation to increase students' scientific literacy. For this study, the detailed guideline including assessment frame for students' argumentation was developed and applied to seventh and ninth grade students. From this application, data were collected from the students' views by pre, post questionnaire and the teachers who had taught to their students by questionnaire including students' attitudes change and applicability. From this study, the result were following. The change of students' perceptions was revealed by questionnaire and the teachers' description. And the applicability of this teaching method was indicated by the teachers' opinion. From these findings, the method was found as applicable teaching method to teach scientific inquiry including scientific argumentation in school science.

The 'Integrated Inquiry' unit is a new addition in the 5th~6th grade science textbooks, and was developed for the 2009 revised national curriculum. The unit deals with six integrated inquiry process skills: problem cognition, formulating hypotheses, controlling variables, transforming and interpreting data, drawing results, and generalization. The purpose of this study is to investigate the perceptions and the teaching practices of elementary school teachers on this unit in their school curriculum and where improvements can be made. Data was collected from questionnaires filled out by 92 elementary school teachers. The results are as follows: First, teachers do have a positive perception on the importance of teaching integrated process skills. Second, with that being true, this unit ended up receiving both positive and negative reviews by teachers. This research found that there were good and bad responses on the educational aspects of this unit in three particular areas: dealing with the development of integrated inquiry process skills, facilitating science learning in other units, and implementing open inquiry. Third, teachers have difficulties particularly in problem cognition, formulating hypotheses, controlling variables, transforming and interpreting data, generalization, and drawing results. There is a lack of student understanding as well as a lack of professionalism for teachers on this unit, and many issues related to the composition of the textbook. This study may have important implications for making improvements in this unit and teaching integrated process skills.

관계추출기의 학습을 위해서는 많은 학습 데이터가 필요한데, 사람이 모으게 되면 많은 비용이 필요하여 원격 지도 학습을 이용한 데이터 수집이 많은 연구에서 사용되고 있다. 원격 지도 학습은 지식베이스를 기반으로 학습 데이터를 자동으로 만들어 내는 방식이기에 비용이 거의 들지 않지만, 지식베이스의 질과 양에 영향을 받는다. 본 연구는 원격 지도 학습을 기본으로 관계추출기의 성능을 향상 시키고, 지식베이스를 확장하는 방안으로 반복학습을 제안한다. 실험을 적은 비용으로 빠르게 진행하기 위해 반복학습을 자동화 하는 시스템을 설계하여 실험을 하였고, 이 시스템으로 관계추출기의 성능이 향상 될 수 있는 가능성을 보였으며, 반복학습을 통한 지식베이스의 확장 방안을 제시한다.

In this paper, we propose an optimal deep learning network architecture for main object location detection through weak supervised learning. The proposed network adds convolution blocks for improving the localization accuracy of the main object through weakly-supervised learning. The additional deep learning network consists of five additional blocks that add a composite product layer based on VGG-16. And the proposed network was trained by the method of weakly-supervised learning that does not require real location information for objects. In addition, Grad-CAM to compensate for the weakness of GAP in CAM, which is one of weak supervised learning methods, was used. The proposed network was tested through the CUB-200-2011 data set, we could obtain 50.13% in top-1 localization error. Also, the proposed network shows higher accuracy in detecting the main object than the existing method.

The purpose of this study is to develop a instructive strategy model of cooperative learning for practical class in technical high school. To achieve this purpose, this study has conducted related literature investigation and interviewed with professionals for reconstruction of practice contents. As a result, 15 steps instructional strategy model of cooperative learning was designed and this model based on traditional 4 steps model, Jigsaw and STAD model which have been verified as effect. To complete the final project, all the team members must cooperate themselves and tutor their peers with learning guides which are constructed as a modular system. This instructional strategy model which is correlated with modular instruction, peer tutoring and cooperative learning is expected to enhance students' school work of psychomotor domain as well as cognitive domain and affective domain.
