The purpose of this study is to develop teaching learning process plans with problem-based learning using book-making applying to the "Dressing and Self Expression" unit and evaluate its effect in middle school home economics for first grade. We developed teaching learning process plans with problem-based learning using book-making including 9 teaching materials for teachers and 15 learning materials for students. Further, we conducted and investigated pre- and post-tests in a form of questionnaires in 167 students from a girls' middle school in Pusan. Teaching learning process plans with problem-based learning using book-making showed positive results in body satisfaction, such as reduction in distortion or less dissatisfaction regarding students' body images. Also, they were found to be less affected by sociocultural attitude towards appearance. The estimation of students included the positive contents that the class was interested with various materials and it provided them with a chance to understand their body. Meanwhile, minor comments pointed out lack of time and complained of the amount of assignments. With these results, we found that teaching learning process plans with problem-based learning using book-making was an appropriate model to achieve the purpose of this study and we suggested that this class might be applied to other units of middle school home economics.

The purpose of this study was to analyze the interactive patterns between teacher and students in middle school earthh science classroom, identify difference of discourse types between earthh science classes taught by majored and non-majored teacher, find the relationship between the discourse pattern and the type of teachers' questions. For that purpose, the participants in this study included four teachers and their students of three middle schools in Seoul. The data consisted of two parts. First, we categorized interaction between teacher and students into the types of discourses by the use of Mortimer and Scott's analytical framework(2003). Second, we classified teachers' questions into four different types of question based on MNeill & Pimentel's classification scheme(2009) to examine for the relationship between the discourse pattern and the type of teachers' questions. As a result, all teachers used interactive/authoritative discourse most in middle school earth science class. Therefore, there was more authoritative discourse to non-majored teacher in comparison with majored teacher. And study demonstrated that the discourse pattern was more related to feedback about student's response rather than the type of teachers' question. In other words, the dialogic discourse showed up more frequently when the teacher used delayed feedback with positive and accepting attitude.

Various data and methods are necessary to help students understand the science subject, and have interest in it. Most students like cartoons, and more easily memorize their contents. The purpose of this study was to verify the effects of science cartoon reading on the academic achiements, the levels of interests in science and scientific attitudes of elementary students The study subjects were four classes of the 6th grade of G elementary school in U city. Two classes were experimental group and the others were comparison group. The students of the experimental classes were encouraged to read science cartoon related to class contents at the beginning and ending for 5 minutes respectively in instructional time. And those of the comparison classes received general science lesson. The results of this study were as follows. First, the experimental classes encouraged to read science cartoon marked higher average score than comparison classes in post-test and the difference was meaningful (p<.05). This meant science cartoon reading treatment had the effect of improvement of the levels of interest in science of student. Second, the experimental classes marked higher average score than comparison classes in post-test but didn't show meaningful difference. This meant science cartoon reading treatment didn't have the effect of improvement of academic achievement of students in our study. Third, the experimental classes marked higher average score than comparison classes in post-test and showed the meaningful difference(p<.05). This meant science cartoon reading treatment had the effect of improvement of scientific attitudes of students. From the results thus far, we could tell that science cartoon reading had positive effects on the levels of interest in science and scientific attitudes of students in our study.

Onto the world-fastest ageing of society, the world-lowest fertility rate prompted a development of various policies and programs for a betterment of the population in Korea. Since the vulnerability of young children of low socio-economic class to malnutrition was clearly shown at the in-depth analysis of the 2001 Korea National Health and Nutrition Examination Survey data, an effort to devise supplemental nutrition care program for pregnant/breastfeeding women, infants and preschool children was initiated. The program was designed to offer nutrition education tailored to fit the needs of the participants and special supplementary foods, using USDA WIC program as a benchmark. Based on the dietary intake of those age groups, target nutrients were selected and their major food sources were searched through nutrient content of foods and dietary pattern analysis. As a result, we developed 6 kinds of food packages using combinations of 11 different food items. The amount of each item in a food package was determined to supplement the intake deficit in target nutrients. Nutrition education in $NutriPlus^+$ aims to improve the nutrition knowledge, attitude, and dietary behaviors of the participants, and is provided through group lessons, individual counseling sessions and home visits. Breastfeeding is promoted with top priority in education for the health of both mother and baby. The eligibility guidelines were set for residency, household income, age, pregnancy/breastfeeding and nutritional risk such as anemia, stunting, underweight, and/or inadequate nutrient intake. Income eligibility was defined as household income less than 200 percent of the Korean poverty guidelines. A pilot study to examine the feasibility of program implementation was run in 3 public health centers in 2005 and expanded to 15 and 20 in the following 2 years. The result of 3-year pilot study will be reported separately along with the ultimate nationwide implementation of the $NutriPlus^+$ in 2008.

In this study, we investigated how the scientific problem-finding ability of pre-service teachers is improved through open-situation scientific problem-making activity. We organized two experimental groups and a control group by degree of participation. The 1st experimental group is an actively participating class, while the 2nd experimental group is a passively participating class. We developed and applied a worksheet for training in problem-making. The pre-service teachers filled in the worksheet for problem-making once a week for seven weeks, then the lecturer gave feedback for every worksheet. We developed and applied a problem finding test in an open-situation to measure their problem finding ability at pre- and post-training. As a result of the training, problem level and diversity improved for pre-service teachers through continuous problem-making activities and feedback. The 1st experiment group significantly improved on the quality and quantity of problems. Especially in the originality, elaboration, verifiability, and variables' category, the 1st experimental group significantly improved compared to the control group and the 2nd experimental group. On the other hand, the quality and quantity of problems of the 2nd experimental group decreased. These results provide a basis for correlation between training attitude and improvement of problem-finding ability. Based on the result of this study, continuous problem-making training and feedbacks are helpful in improving the problem-finding ability of pre-service teachers.

In this study, in regard to the change of the paradigm to STEAM (Science, Technology, Engineering, Arts, and Mathematics), we have looked into the ways to apply scientific inquiry through the arts, discussed the educational implications for the ways to step forth with the science and the arts in educational field. In the development of the strategies related to the optical illusion arts, to make sure that the design-oriented science education to reach its goal to make effective teaching, students need to be understood in the method of the artistic designs. Totally it had two rounds for inspection about operation of the convergence with curriculum. As a result, students changed attitude to concentrate in class naturally while doing their art work, participating in person rather than simply looking. It is caused by the scientific approach to strategy of illusion arts. In addition, we could see that students change into a proactive manner as well as teachers comments that they are communicate and make a complete the work with others. A lot of researches give that science can provide the ideas as a method to arts, arts can provide creative ideas to science, but it is still lacking that research can be applied to education specifically on how to. An efforts in the number of collaborative research will continue to introduce, as this study STEAM of science and arts in the field of education be shifted paradigm.

The purpose of this study is to compare and analyze the effects of teaching based on learning-communities approach to mathematics for 7th grade students. Two classes of 7th graders at two different middle schools in same city were selected as the experimental group and the control group respectively. Students in the experimental group learned mathematics in a learning-community while their counterparts in the control group received the traditional whole-class instruction employed in most schools. The results are as follows. Firstly, there was no statistically significant difference in mathematics achievement between the experimental group and the control group. Secondly, between the two groups, there were statistically significant differences in students' attitudes toward mathematics. Participants enjoyed the learning process itself by asking difficult questions to one another, sharing their ideas freely and figuring problems out for themselves. During these active participations, they displayed more confidence and interest in learning mathematics.

Traditional music should be succeeded and developed through the systematic education since music represents culture and history of one country. In Korea, even through the importance of Korean traditional music has been emphasized through the seven times of revision of national curriculum, music education has been still Western-oriented. This study aims to make students have experience Uttari Samul-nori and investigate the perception changes about the Korean traditional music. It is ultimately expected that students inherit the Korean traditional music and further recreate our own traditional culture. Samul-nori class was organized in the regular music curriculum twice a week, for 10 hours and various activities were tried during that time. 1st-year high school students participated in this research and they were allowed to play Samul instruments directly and play the basic rhythm suggested in the newly designed curriculum. Before and after the research, the questionnaires were sent to examine the attitude changes toward the Korean traditional music. The result of the questionnaire are as follows: First, Samul-nori activities affect positively the students' interest in the Korean traditional music and Samul-nori itself. Second, Danso(short bamboo flute) education which has been implemented most frequently during the Korean music education, is not satisfactory to the students. Third, students were satisfied with the new teaching method of Samul-nori and most students wanted to continue to take Samul-nori class. Last, students recognized the importance of Korean traditional music education after the research activities.
