This study is aimed at development of pedagogical content knowledge on fraction in the elementary school mathematics. Elementary students regard fraction as the difficult topic in school mathematics. Furthermore, fraction is the fundamentally important concept in studying mathematics. So it is important to develop the pedagogical content knowledge on fraction. The reason of attention to the pedagogical content knowledge is that improving the quality of teaching is the central focus of a high quality mathematics education. Shulman suggested that various knowledges are required for teacher to improve their classes. Of course, pedagogical content knowledge is the most valuable in teaching mathematics. Pedagogical content knowledge is related to the promotion of students' understanding about the learning. Pedagogical content knowledges are categorized by five factors in this study. These are understanding about curriculum, understanding about students and students' knowledge, understanding about teachers and teachers' knowledge, understanding about the methods, contents, and management of class, and understanding about methods of assessments. I develop the pedagogical content knowledge on fraction according to the these categories. I concentrate on the two types of pedagogical content knowledges in developing. That is, I present knowledges which teachers have to know for teaching fraction effectively and materials which teachers can use during the teaching fraction. Pedagogical content knowledges guarantee teachers as the professionalists. Teachers should not teach only content knowledges but teach various knowledges including the meta-knowledges which have relation to fraction.

The purpose of this study is to investigate research trends about convergence and integrated science education through the analysis of theses published from January, 2000 to June, 2011 in the scientific journals. For the analysis of the theses, we set standards of analysis including the number of theses, integrated types, research methods, the designs of study and the objects of study. The number of theses used for the analysis were 110 volumes and these were limited to the Journal of KASE (The Korean Association for Science Education) and Journal of KESES (The Korean Society of Elementary Science Education). The results of the study are as follows. First, in the analysis of theses according to the published year, we discovered that the volumes of theses related to convergence and integrated science education were only about 10% of theses published in the journals. Second, the theses about STS education and integration type were the most common type in the integrated types, and the next things were integration type with other scientific fields, and integration type with other subjects. Third, 50% of theses have focused on the 'analysis of effect' as research methods and 45.5% of the theses have used 'quantitative research' as the designs of study. Fourth, the most common study in the theses was to target elementary school students, then it was middle school students, then high school students, literature, teachers, would-be teachers, and the general public. On the basis of the results of this research, we suggest that various studies can develop student's creativity and teacher's recognition through STEAM education and must be presented for the successful STEAM education.

The purpose of this study was to find an implication for a direction to improve professional development in mathematics by exploring elementary school teachers' perception of the need for professional development in mathematics. To this end, 4 elementary school teachers were organized into one focus group, and group discussion materials were collected and analyzed based on cases of mathematics professional development needs. As a result of the study, the elementary school teachers' perception that the need for professional development in mathematics is both unnecessary and necessary. The perception of unnecessary was influenced by the easy level of elementary school mathematics content and the ease of teaching. Also, the perception of necessary factors were considering various aspects of mathematics teaching, changing the accumulation of failures in mathematics classes, maintaining authority of students, demand for class improvement due to social change, the impact of school work, the influence of the community of professional development and peers in school, and efforts to grow as teachers. Based on these results, the author discussed ways to promote teachers' participation in mathematics professional development by considering elementary school teachers' perceptions of the need of mathematics professional development.

This study compared the perceptions of children and their mothers of the effects of school lunch programs on the children's dietary behaviors in elementary schools. Questionnaires were answered by 425 elementary school students and their 412 mothers in the Busan area. The results indicated: The school lunch program had positive effects on children's dietary behaviors such as understanding healthy meals, correcting unbalanced diets, snack intake, attitude toward the meal, table manners, and table hygiene. However, there were still some negative habits in the home related to snack time, reading books or watching television during mealtime, eating foods before seniors have started. The gender of the children and whether the mothers worked or not produced no significant differences (in most cases). Still mothers more positively perceived the effect of school lunch programs on their children's dietary behaviors than did the children themselves. Thus, the school lunch program had positive effects for a balanced diet and making good eating habits. And, therefore, teachers-as well as the dieticians- should actively regard the school lunch program as an educational activity which can produce positive effects for a balanced diet, and make every endeavor to strengthen their relationship with the home.

Science career education is for every student as well as for students who want to become scientists. In this study, we developed and applied science career education materials using TV programs which showed successful application of science in industry and business. The effects of the programs were surveyed mainly by questionnaire on 'Science Career Orientation', which have four categories.Video materials using TV programs were effective in changing science career orientation (p<0.05) of junior high school students, but only when the teacher added some cognitive explanation on the scientific concept involved. Providing only video materials were not enough to make meaningful change on science career orientation. The results implied science career education should be linked with science teaching and learning. It also showed the possibility and the way of using informal education like TV program in science career education.

This paper analyzes the level of satisfaction of two groups of teachers who were educated about artificial intelligence using App Inventor. The participants were 13 pre-service and 9 in-service elementary school teachers and the data was collected using a questionnaire. As a result of the study, in-service teachers were all more satisfied than pre-service teachers in terms of interest, difficulty, and participation in the education. In addition, the questions investigating whether education helped motivate learning of artificial intelligence and whether there is a willingness to apply it to elementary classes in the future were also more positive for in-service teachers than for pre-service teachers. In general, pre-service teachers had somewhat more negative views than in-service teachers, but they were more positive than in-service teachers in terms of whether the education helped improve their understanding of artificial intelligence and whether they were willing to participate in additional education. Analysis of the Mann-Whitney test to see if there was a significant difference in satisfaction between the two groups showed no significance. This may be because most of the students in the two groups already had block-type or text-type programming experience, so they were able to participate in the education without any special resistance or difficulty with App Inventor, resulting in high levels of satisfaction from both groups. The results of this study can provide basic data for the future development and operation of programs for artificial intelligence education for both pre-service and in-service elementary school teachers.

The purpose of this study is to investigate the recognition of food allergies and dietary attitudes in elementary school students. For the food allergy symptoms, they responded 'skin trouble' 63.6% the most. For the causing foods of allergies, they responded, 'I don't know the causing foods' 33.5%, 'I was diagnosed' 51.0%, 'I was treated' 63.9%, and therefore 'I restricted foods' 53.5%, due to 'I restricted foods through hospital diagnosis' 40.5% the most. For family history, 67.9% responded the family history matters. 70.3% responded the seasons would not affect to the symptoms. 64.1% responded the cause of food allergy is specific foods. For allergy solution, they responded, 'I don't use any treatment' 42.8% the most. For effective treatment, they responded, 'I restricted causing foods' 45.1% the most. Recognition of food allergies by food allergy experience showed a significant difference in the items such as 'have heard or known about food allergies'(p<.001), 'whether participated in consultation and training'(p<.001), 'problems of growing children when putting limits on causing foods'(p<.001), 'interests in getting information about food allergy'(p<.001), 'feeling the needs of allergy education about careful foods'(p<.01), 'wish for schools to be educated'(p<.01). Dietary attitudes by food allergy experience showed a significant difference in reason of unbalanced diet(p<.001).

The purpose of this study was to explore how primary school students develop their interest in science. A survey questionnaire was used to investigate students' interest, change of their interest, and engagement in science related activities three times a year. 201 students of two primary schools in Seoul Metropolitan City initially participated in this study. A follow-up case study was conducted with students who showed an increased interest in science. Finally, seven students were chosen in the case study. They were asked to keep a photo journal for 12 weeks, and were interviewed in every other week by one of the researchers. Among these seven participants, two (TK and QQ) were chosen for analyzing their data in this case study because they showed positive changes in developing science interest throughout the study. The results of two participants' survey, photo-journal and interview were analyzed qualitatively. First, TK, whose science interest developed from situational interest II to individual interest I, engaged in doing experiments at home, doing mathematics activities, raising pets or plants, observing phenomena, and visiting informal educational centers. He tended to participate in hands-on activities by himself in out-of-school settings. Second, QQ who developed from situational interest I to situational interest II, engaged in taking pictures as a representative activity at home and school. He tended to participate in activities with either his father or one of the researchers. Both students showed personal characteristics such as doing place-based activities, interaction with others and activity subjectivity. The goal of TK's interactions with others on the various places was to develop in cognitive domain. On the contrary, QQ's goal of interactions with others was to develop in emotional communication. This study reported the cases of characteristics of students who developed their interests in science including activities in- and out-of-school settings and their accompanying people.
