This study has investigated the way to improve the communication skills emphasized in mathematics education, and analyzed the effects of Communication Oriented Mathematics Lessons on the mathematical disposition and the academic achievements. For this research, two groups of first grade students from D elementary school in Daegu city were selected which had been proved homogeneous in mathematical disposition and academic achievements via a preliminary test. The experimental group was given Communication Oriented Mathematics Lessons (COML) while the control group was given Traditional Classroom-based Instruction (TCI). COML were given along with first grade, first level mathematics for eight weeks, to improve communication skills of the students who were unfamiliar with mathematical communications. The schemes for the education include revising, summarizing, asking questions, and participating. The results of the study were summarized for mathematical disposition and academic achievements. First, COML is effective to evaluate the will to solve problems in the mathematical disposition of the students, and to make it useful for them to live their lives and to learn other subjects. Second, previous studies have shown contrary interpretations on the effects of COML. This study has found that it does not improve the students' scores on the original form of academic achievement test.

This study aims to design, develop the impact of a high school course in practical problem- focused teaching plan which will enable students to deal with an aging society, and prepare well for the aging by looking at issues the elderly face. This study set a target of analyzing the 2007 revised curriculum manual to develop instructor-led teaching and learning plans for 'Successful aging preparation'. Five common subjects were reframed on a practical problem basis through factor analysis of preliminary research regarding aging education for teenagers and the 2007 revised curriculum and textbooks of Technology Home Economics, and Human Development. The practical problem was 'What do we need to do to Successfully live an independent life in aging?', and the subjects studied to answer this question were the aging society and population changes. the nature of the elderly, aging preparation, care of the elderly, and welfare services for the elderly. These five subjects were grouped under the main categories of The Aging Society. Understanding the Elderly, and aging Preparation. The ultimate objective of the lessons was, through critical reasoning, to inquire into the causes of current problems the elderly face so that teenagers can understand aging societies and the elderly, and prepare for a Successful aging. Another objective was to seek reasonable alternatives for teenagers as they prepare for Successful and independent aging, and increase their problem-solving abilities in choosing the best course of action by considering the ripple effect of consequences of each of those alternatives. The practical problem-teaching lesson plans consisted of five classes on practical reasoning instruction. This study suggests that new high school curricula should include lessons on preparation for aging so that students can deal successfully with our aging society.

The purpose of this study was to develop and apply the practical problem-based teaching·learning process plan for 'interacting with neighbors' of home economics subject. The plan consisting of 3 lessons has been developed and implemented according to the ADDIE model. Various activity materials (7 student's activity sheets, 3 reading texts, 1 homework sheet, 3 sets of ppt, 6 videos, and 3 teacher's reading texts) as well as questionnaire were developed for the 3-session lessons. The plans were implemented by the researcher to 204 freshmen, 8 classes, of C middle school in Seoul during september, 2017. The result, of students' lower level of actual participation in interacting with neighbors comparing to their interests in, supported the need of this study. Students were satisfied with the whole 3-lessons in the aspects such as beneficial usage of the contents in their daily life and in building the sense of community, as well as adequacy of materials and activities. Students also reported that they would highly aware to the importance of interacting with neighbors and to practice the contents learned from the lessons in daily life at community. They had an opportunity to reflect one's own attitude to neighbors and recommended to teach it to other schools, too. It can be concluded that the teaching·learning process plan for 'interacting with neighbors' would raise students' housing values living together and attain the overall objective and achievement standards of 2015 home economics middle school curriculum.

The purposes of this study were to develop PBL programs for class, and to examine the effects of PBL. The 2 PBL experiencing the roles of "fashion editor" and "fashion stylist" were conducted in "Fashion & Social Culture" and "Fashion Design" parts. The objects were 29 students in Home Economics Education Department. The effects of PBL were observed through contents analysis to reflective journals. Also, self assessment and learning satisfaction were analyzed. The effectiveness of PBL presented in reflective journals were 'understanding of cooperative learning', 'related knowledge adaption', 'real experience', 'self-examination & changed self', 'problem solving ability'. Also students' self-assessment and learning satisfaction were very high in two PBL programs. However, they had difficulties in co-working and lack of time.

In 21th century moving rapidly up to the knowledge and information society, creative problem-solving abilities are preferentially required to engineers. Though there may be various approaches to develop such abilities, PBL instruction method can be an effective alternative to develop such abilities. Recognizing this, one 'JPBL' model was constructed and introduced in this study. The model was developed independently based general existing PBL models and applied to university students to analyze its effectiveness in the aspect of class satisfaction and organizational commitment. Based on results, the meaning and limitation of the model development were discussed.

This research is to develop ethical clothes consumption education program that adopts PBL which is student centered professor-learning method where the learner actively participates in lessons to recognize problems and solve them. This research also tried to see the changes in the students' ethical clothes consumption awareness and problem solving skills and self-directed learning ability after applying this program to lessons. With total of four study topic, seven ethical clothes consumption education programs were developed, and the actual lesson was conducted in controlled group and experiment group. Summary of this research is as followed: First, ethical clothes consumption education program was developed using PBL. Second, teenagers' ethical clothes consumption awareness increased much more than before the course. As both the control group and the experiment group were proven to have high ethical clothes consumption involvement and awareness, it was possible to confirm there is a need for systematic and continuous consumption education at school. Third, when a post test on changes in problem solving ability and self-directed learning ability after applying PBL based ethical clothes consumption education program was conducted, students' problem solving ability was enhanced and both factors, the awareness and behavior of self-directed learning, showed significant difference.

21C future learners are required to have creative thinking and problem-solving capability to address an issue wisely by integrating and applying knowledge and functions. The robot education that has recently been studied in primary and secondary schools was reported to be effective in satisfying the requirements. The robot education varies ranging from the existing after-school education to an integrated approach used for regular curriculums, and has actively been studied. Nevertheless, aside from positive study results, any studies on the environment where primary school students can learn robot and programming knowledge more friendly is still insufficient. Therefore, this study was intended to give students a robot class with the use of storytelling friendly to students in order for primary school students to learn robot and programming knowledge with ease. The study result showed that acquirement of programming knowledge was improved, and that the students had a positive learning attitude. In addition, it was found that the storytelling of the robot class helped provide the entire learning context and continuous learning motivation for the students.

The purpose of this study is to verify the effectiveness of the Development-oriented model (Discovery-Design-Development: DDD) for developing students' Computational Thinking skills in software education. DDD is a class model that learns the process of developing SW to solve real-life problems through three stages of Discovery, Design, and Development. In order to verify the effectiveness of the DDD, first grade students at G university who did not have SW education class were tested. As a result, the students who experienced SW development through DDD maintained the learning motivation of SW education before and after, especially the confidence area increased significantly. In addition, students also noted that the Design phase was particularly helpful in improving CT abilities and the DDD was a significant help in understanding of decomposition and algorithms.
