If students can use mathematics to solve their problems and learn the mathematical knowledge through it, they may think mathematics useful and valuable. This study is for the teaching through problem solving in mathematics education, which I consider in terms of the problem-based learning and mathematical modeling. 1 think mathematical modeling is applied to teaching mathematics as a problem-based learning. So I developed the teaching model, and showed the example that students learn the formal and hierarchic mathematics through mathematical modeling.

The ethical problems related to climate changes have basically different character from the ethical problems which we have experienced until now. In order to approach ethical problems of climate changes for forseeing, mitigating and adapting many complicated situations which result from climate changes we should breake away from the point of anthropocentrism at first. Secondly, the education of the ethics of climate changes is very important in all levels of schools. It is very important and urgent to decide what and how we should teach. Finally, the sustainability has important role in the justification of why and what we should take actions against climate changes.

The purpose of this study was to develop and implement a home economics convergence education program applying problem-based learning method focusing on the middle school food and nutrition life unit, and verify the effect of this class on the problem-solving ability of students. For this, the study set up the theme of 'sustainable life' by examining the relationship with other subjects, and set the key question as 'what is the relationship with the environment of food resources, the influence of individual level, and the solution method?' was postulated. And developed the problem and the total of 8 classes. As a result of conducting the convergence education program with home economics applying problem-based learning method, the pre-test and post-test scores were 3,54 and 3.96, respectively, which showed a significant increase in problem-solving ability (p<.001). There were significant differences in the dimensions of problem-solving ability, except for problem clarification. Therefore, it was confirmed that the home economics and convergence education program applying problem-based learning method is an effective class for improving students' problem-solving ability.

Web-based distance teacher training should focus on increasing self-directed problem solving skills of trainers by problem-based instruction(PBL). Performance assessment evaluates achievement of learning goals through the practical performance learning to solve problems in the real situation. This study proposes a web-based performance assessment model for the distance teacher training. It reflects fairness and objectiveness issues of performance assessment which elementary teachers are concerned about through the survey on distance teacher training, and relieves instructors from overload of managing and scoring performance tests. The proposed model provides problem-based learning situations, interactions between individuals and groups, and web-based cooperative evaluation and the peer evaluation.

본 연구는 기존의 소프트웨어 교육 방법이 가지는 문제점을 분석하고, 이를 해결하기 위한 방안으로 존듀이와 프레네의 경험 중심 교육 방법에 기반을 둔 새로운 소프트웨어 교육 모델을 제안한다. 경험 중심 기반의 새로운 소프트웨어 교육 방법은 학습자들의 자율성을 보장하고, 학습자들 간의 상호작용을 통해 일상생활의 문제점을 해결할 수 있는 문제 해결력을 기르는데 중점을 두고 있다. 따라서 본 연구는 자유로운 사고방식으로 일상생활의 다양한 문제를 발견할 수 있는 능력과 다양한 경험을 통해 이를 해결할 수 있는 능력을 기르도록 체계화된 소프트웨어 교육 모델을 구성할 것이며 이를 통해 소프트웨어 교육의 발전에 기여하고자 한다.

This study was to compare the contents and practical problems addressed, the process of teaching-learning method, and evaluation method of Korean Home Economics curriculum and of the Oregon and Ohio's Practical Problem Focused Family & Consumer Sciences Curricula. The results are as follows. First, contents of Korean curriculum are organized by major sub-concepts of Home Economics academic discipline whereas curricular of both Oregon and Ohio states are organized by practical problems. Oregon uses the practical problems which integrate multi-subjects and Ohio uses ones which are good for the contents of the module by integrating concerns or interests which are lower or detailed level (related interests). Since it differentiates interest and module and used them based on the basic concept of Family and Consumer Science, Ohio's approach could be easier for Korean teachers and students to adopt. Second, the teaching-learning process in Korean home economics classroom is mostly teacher-centered which hinders students to develop higher order thinking skills. It is recommended to use student-centered learning activities. State of Oregon and Ohio's teaching-learning process brings up the ability of problem-solving by letting students clearly analyze practical problems proposed, solve problems by themselves through group discussions and various activities, and apply what they learn to other problems. Third, Korean evaluation system is heavily rely on summative evaluation such as written tests. It is highly recommended to facilitate various performance assessment tools. Since state of Oregon and Ohio both use practical problems, they evaluate students mainly based on their activity rather than written tests. The tools for evaluation include project documents, reports of learning activity, self-evaluation, evaluation of discussion activity, peer evaluation in a group for each students for their performance, assessment about module, and written tests as well.

As the interest in software education grew, the Ministry of Education was also required to provide software education for practical course of grades 5-6. In this study, learner-centered evaluation was applied to software education to analyze its effectiveness. It is hoped that many teachers will apply learner-centered evaluation to software education to become more effective software education in school. In a learner-centered evaluation, students can expect positive effects by actively participating in classes and engaging in active learning activities. Through learner-centered evaluation, we have taken into account the various background variables to see how students' three aspects, creativity, problem-solving ability and information-use ability change, and how learner-centered evaluation affects these abilities in software education. The result of research have shown that in software education, learner-centered evaluations have all had significant effects on creativity, problem-solving ability and information-use ability, as well as the existence of entry/scratch study experience.

Scratch, one of the educational programming languages, provides a media-rich programming environment and easy interface to users. It supports Korean language and is utilized usefully in programming classes in elementary and middle schools. However, programming causes cognitive loads to young students. Because the programming process is a complex problem solving procedure that requires logical and abstract thinking abilities. Therefore, we developed a problem based scratch programming teaching and learning model to enhance intrinsic motivation of learners and to maximize the effects of using the scratch, educational programming language. The developed problem based teaching and learning model considered elementary students' characteristics. It was implemented in fifth grade elementary school classes and the educational effects of the model was analysed. The developed model was helpful in enhancing students' problem solving potential and logical thinking abilities.
