  • The purpose of this study is to examine the effects of the Portfolio applied science instruction on the students' scientific affective domain and perceptions of portfolio in elementary schools. Portfolio applied science instruction of the 6th grade science unit 'Environment pollution and Nature protection' was developed for this study. Traditional instruction was implemented to the control group and portfolio applied science instruction was implemented to the experimental group. Pretests of the scientific affective domain were administered to both groups. The treatment was given for about seven weeks for both groups. Instruments about scientific affective domain were administered to both groups. A questionnaire on perception of portfolio applied science instruction was given to the experimental group after the treatment. The results were analyzed using t-test on the students' scientific affective domain. The results of this study are as follows: 1. Portfolio applied science instruction program for elementary schools was developed. Students themselves determine the portfolio learning goal in a portfolio applied science instruction. Students construct the portfolio and they evaluate themselves and other colleagues. Also teachers go on portfolio applied science instruction considering portfolio purpose, concepts, evaluation. 2. There was not a statistically meaningful difference between an experimental group and a control group o]1 the students' scientific affective domain. In three sub categories of a scientific affective domain, the science perception, the interest on science and scientific attitude, there were not statistically meaningful difference among them. 3. As the results of the questionnaire on perceptions of portfolio, they didn't understand it very well but after learning portfolio, they showed positive attitude to perceptions of portfolio. Students in portfolio applied science instruction like more the portfolio applied science instruction than general instruction. 4. Portfolio applied science instruction has an useful value as a method of teaching and evaluation. Students and teachers can produce various portfolios products in portfolio applied science instruction. As a conclusion, portfolio applied science instruction was not statistically meaningful on the students' scientific affective domain, but it gives positive effects on perceptions of portfolio in elementary schools. Therefore, portfolio has an educational value as a method of teaching and evaluation for students' growth. In the future, teachers and students must have interaction and feedback in portfolio applied science instruction.

  • The purpose of this study was to analyze the reading materials in 7th curriculum and 2009 revised high school chemistry I textbook for identifying the problems of reading material presented in science textbooks and to investigate science teachers' recognition about utilization reading materials in science textbook. For this purpose, each four 7th curriculum and 2009 revised high school chemistry I textbook were analyzed according to the number of reading materials, the type of contents and the type of students' activities. In addition, the secondary school science teachers' recognition about utilization reading materials in science textbook was investigated. The results were as follows: First, anylizing reading materials in chemistry I textbooks showed that and the rate of reading materials were presented from 7.9 to 17.1% in 7th curriculum and from 20.6 to 28.2% in 2009 revised curriculum textbook. It implies that the rate of reading materials in 2009 revised textbooks increases more than those in 7th curriculum textbook. The result of analyzing the type of contents, 'life sciences' was the largest proportion with 34.3 % in the 7th curriculum chemistry I, but 'enrichment and supplement of knowledge' was the largest proportion with 23.7% in 2009 revised curriculum. Analyzing the type of student activities, only 13% of the reading materials in 7th National Curriculum textbook was found to be inquiry type, but 35% of the reading materials in the 2009 revised curriculum. appears to be inquiry type. It suggested that the curriculum objectives was reflected in the textbook. Second, investigating recognition of teachers' perceptions of utilization science textbooks, 67% teachers responded that they used the reading materials in their science class, but teachers who didn't use the reading materials was almost 33%. A large number of teachers responded that the reading materials associated with the real-life needed for integrated education and thought that the reading materials about 'life and science' should be included in the science textbooks.

  • Middle school students' conceptual changes on physics, chemistry, biology and earth science concepts which were intentionally selected by researchers had been investigated through traditional teaching and learning by paper and pencil tests and P.O.E. The weak points had been studied by individual interviews about the problems of traditional science classroom teaching after students' testing and learning about science concepts. As results, students' conceptual changes could be hardly found through traditional teaching and learning except several concepts in biology, The weak points of traditional science classroom teaching and learning were as follows: 1) Teachers teach science as finding answers. 2) The conventional science test is not performed to find students' concepts out but to recall simple knowledge or calculus. 3) Students hesitate to ask teacher Questions in science class because of their colleagues' or teachers' blame. These mean that science teachers need specially designed teaching methods on the students' concepts and reseachers had to study about science classroom socialogy, what happened in science classrooms.

  • This study aimed to investigate changes in metamodeling recognition among chemistry teachers through a teacher educational program related to redox models and water electrolysis experiments. To this end, a science model education program was developed for 9 chemistry teachers and conducted over 10 lessons for a total of 40 hours. In addition, a pre- and post-survey was administered to determine teachers' metamodeling recognition in non-contextual and contextual situations. As a result of the study, through the science model education program, teachers showed educational effects in both non-contextual and contextual situations. In the case of non-contextual situations, the stages of scientific metamodeling knowledge development of chemistry teachers came out differently depending on the type of question. For example, the nature or purpose of the model, the modeling process, or the evaluation and improvement of the model improved from low to high, but there was no significant change because the perception of model change and diversity was already high in advance. In the case of contextual situations, the stage of scientific metamodeling knowledge development improved from objectivity to subjectivity in both the redox model theory class and the water electrolysis model experiment class. Therefore, through the 5E circular learning model-based education program, chemistry teachers' perception of metamodeling was clearly improved. However, the modeling activities of teachers in the water electrolysis model experiment class were different from the change in metamodeling perception. The types that teachers selected as additional experiments for modeling were analyzed in two ways. The first type is when they are interested in finding an ideal condition in which the ratio of hydrogen and oxygen gas is close to 2:1 through additional experiments. The second type is when additional experiments are designed with interest in why the experimental results are coming out like that. It was analyzed that the second type was the experiment necessary for modeling. In addition, modeling activities were analyzed into two types. The first was a type in which water molecules were directly decomposed in two electrodes to generate hydrogen and oxygen gas. This type was the case of regression to the textbook model regardless of the experimental results, and 6 chemistry teachers out of 8 were analyzed as this type. The second type was the type in which water reacted at the (+) electrode to generate other substances, and hydrogen ions reacted at the (-) electrode to generate hydrogen gas. Teachers who performed these modeling activities corresponded to the second type in additional experiments, and 2 chemistry teachers out of 8 corresponded to this. Therefore, it is necessary to provide an experience of activities corresponding to the second type of experiment and modeling through an educational program that provides an experience of directly modeling through experiments in order to develop modeling capabilities, unlike the development of metamodeling knowledge.

  • For STEM education science teachers usually choose topics which are related to both science and other disciplinary contents. Nevertheless it is not clear for the teachers to adopt what kind of criteria for their choices. Interdisciplinary teaching is not a mixture of science content with another one from different disciplines as resources for the content teaching. Instead the criteria and perspectives for the integration need to be clearly defined. In this study we investigated how to integrate science and other disciplines in terms of interdisciplinary teaching. Family resemblance approach by Wittgenstein, recently revised by Erduran and Dagher, was applied to comparative analysis of science, math, and physical education curriculum documents in Korea. Aim and value, methodological rules and methods, knowledge, and activities in each discipline were compared and analyzed with the view of FRA. Results of the study described alternative criteria of how to find appropriate topics for interdisciplinary teaching.

  • In this study, we examined elementary school teachers' needs for environmental education (EE) in order to effectively implement EE in the elementary school. The participants were 113 elementary school teachers in Chungcheongnam-Do. Twenty items were adapted from the Environmental Education Needs test, and the teachers were asked to respond to each item on a 5-point Likert scale. For the items of the subcategory of EE training, teachers' preferences between the on-site and the online training were also asked. Although the teachers showed relatively strong needs for most items of both the subcategories of EE service and EE training, they exhibited stronger needs for the items related to the services and/or the content of training readily applicable to EE classes. Teachers preferred the online training to the on-site training in most items whereas their preferences to the on-site training tended to be relatively high in the items such as the use of local nonformal EE site, the development and the use of outdoor EE site, and the EE teaching strategies. Educational implications for the effective EE are discussed.

  • Purpose: This descriptive study was conducted to compare the teaching status, utilization of the teaching materials, and the need to solve matters of sex education between the school health educators and teachers working in an elementary school in Busan. Method: 182 school health educators and 125 teachers participated in the research. Data was collected using a self-administered questionnaire, and analyzed by frequency and x2 -test using the SPSS WIN 10.0 Program. Results: While school health educators carried out most of the sex education in the extra curriculum and physical education class, teachers did in the regular curriculum and physical education class. Regarding the utilization of the teaching materials on sex education, although the majority of school health educators used the teacher's manual, only a few teachers used it. Most of the school health educators used the ICT teaching materials while only half of the teachers did. Regarding the methods to solve matters on sex education, school health educators responded that a sex-related subject should be combined with a health subject, and an independent sex-related subject was necessary. The teachers, however, responded that it was necessary to secure enough time for sex education, the sex-related subject combined with a health subject was necessary, and there is a need to designate a sex educator. Conclusion: School health educators utilized more teaching materials for sex education and suggested more active methods to solve matters related to sex education. Therefore, school health educators should be more active as sex educators, and the subject of sex education should be adopted as a regular course.

  • This study was conducted to gather basic data on the tasks and roles of nutrition teachers by analyzing the changes inwork importance, performance frequency, and organizational environment after dietitians were transposed to nutrition teachers. E-mail surveys were sent to 100 newly assigned nutrition teachers who previously served as dietitians in Gyeonggi province. A total of 72 teachers responded to the survey. The respondents were asked the importance and frequency of 9 work-related duties performed as a dietitian and nutrition teacher, respectively. They were also surveyed regarding their satisfaction perceptions for 5 organizational changes. The majority of respondents were 36 to 40 years old (48.6%) and had 10$\sim$20 years of work experience (58.3%). Significant differences were found for work importance after changing to the role of nutrition teacher (p<0.001). In addition, work performance frequency differences were found for the categories of nutrition education, nutrition counseling, and dietary guidance. These results were attributable to the differences in work importance and performance frequency by now being a nutrition teacher rather than a dietitian. The respondents had increased satisfaction levels after changing from dietitian to nutrition teacher (p<0.001) in terms of 'pride for change in work', 'satisfaction level for pay', and 'satisfaction level for change in the organizational environment'. In order for nutrition teachers to have effective work performance, 'personal capabilities' and 'school manager support' should be coordinated. Overall, the results of this study suggest that effective training programs should be developed for nutrition teachers they can effectively complete newly assigned work tasks.

  • The purpose of this study is to explore the relative influence of psychological well-being and social support on the burnout of infant care teachers. Participants were 194 infant care teachers from 52 infant daycare centers in Gyeong-gi-do. Psychological burnout was assessed by the Maslach Burnout Inventory(Lee, 2011), psychological well-being was measured by the Psychological well-being scale(Cho & Cha, 2001) and social support was measured by the social support questionnaire(Bak, 1985). Date were analyzed using descriptive statistics and analysis, t-test, Pearson's correlation analysis, and multiple regression analysis. The major results of this study were as follows; First, there were differences in burnout in terms of marital status, work experiences, classroom operation type and income. Second, Infant care teachers' burnout was negatively correlated with psychological well-being and social support. Third, the most influential factor on infant care teachers' burnout was purpose in life, the second most influential factor was self-acceptance, the third most influential factor was emotional support, and the least influential factor was environmental mastery. Results of this study indicate that a psychological well-being enhancement program should be developed and emotional support from a social relationship network should be enhanced in order to prevent infant care teachers' burnout.
