The principal objective of this study was to assess perceptions and preferences of chungkukjang in elementary school children who used a school foodservice. In this investigation, 583 elementary school students(300 boys, 283 girls) in the Seongnam area were surveyed via questionnaire, and the collected data were analyzed using the SAS package. The results demonstrated that 82.0% of students responded that they were aware of chungkukjang. Female students were more aware of chungkulgang than were male students, and children of the nuclear families were more aware of those of the extended family. With regard to the origins of their interest in chungkulgang, 51.8% of the subjects answered 'through home education' and 35.5% learned about chungkukjang 'through mass media'. Most students recognized chungkulgang as a 'healthy food' and a 'Korean traditional food'. Approximately 44% of the students ate chungkukjang in the school foodservice once per month, and 41.7% preferred this menu. Therefore, in order to increase elementary school students' knowledge and intake of chungkulgang, the school should attempt to foster the quality of chungkulgang in nutrition education, to serve chungkukjang frequently in school foodservices, and to develop recipes for tastier chungkukjang foods for children.

This study examined the needs analysis of school-based staff development at the elementary school level in rural areas of Kyungki and Chungnam provinces. Using a modified survey, the Korean School-based Staff Development Needs Assessment Survey (KSSDNAS), adapted from the Teacher Needs Assessment Survey (TNAS) developed by Gary M. Ingersoll et al. and the Korean Teacher Needs Assessment Survey (KTNAS) developed by K. Chung, the study analyzed 192 teachers' responses. In order to analyze the data, frequency, factor analysis, cross-tabulation, and one-way ANOVA were computed. The findings of this study indicated that there were significant differences between years of teaching experience and the teachers' perceptions of school-based staff development needs. These involved "building learning objective and learning group "and" cooperation of classroom management and students' activity". However, elementary school teachers' perceptions of their school-based staff development needs were not significantly influenced by school size or school location. Most of all, it may be suggested that active teachers can improve the achievement of their rural schools by rearrangement of the subject contents and by understanding their students in rural areas.

This study is to consider the fundamental perceptions of pre-service elementary school teachers to natural environments. The recognition items of questionnaire for those environments include ones of water, atmospheric, soil, biologic and oceanic environments constituting of the earth system. From the results of the study, they affirmatively recognized biologic environment, but they showed highly negative recognitions to others. In other side, it is considered that their recognitions to natural environments were probably transferred by the things which involve press media, curricula and real lives. On the basis of the study results, systematic teaching-learning for natural environments is essential because the encouragement of eco-friendly attitude, one of main goal for environmental education, is budded from basic understandings to natural environments. Affirmatively environmental worldviews for elementary school students are important for reasons why teacher's quality and practice will is fundamental, and then teacher could change the views of the students for environmental education. So, preparing balanced attitudes, right concepts and connection to applicable knowledges for natural environments, pre-service elementary school teachers in environmental education must be pointed to organized education between human and natural environment.

In National Curriculum of Science revised in 2007, free inquiry was newly introduced to increase student's interest in science and to foster creativity by having students make their own curiosity questions and find answers by themselves. The purpose of this study is to analyze elementary school students' perceptions on free science inquiry activities applying a brain-based evolutionary approach. For this study, 106 the fifth grade students participated, and then completed a questionnaire on free inquiry activities according to a brain-based evolutionary science teaching and learning principles. The students performed a series of steps of the Diversifying, Estimating-Evaluating-Executing, and Furthering activities in each of Affective, Behavioral, and Cognitive domains (ABC-DEF approach) and constructed their own free inquiry diary, then the observations by the researcher and interviews with the students were analyzed both quantitatively and qualitatively. The major results of the study were as follows: First, the majority of the students perceived the each domain and step positively although a few of them perceived negatively. The reasons perceived as negatively were categorized into two; preference dimension of like or dislike and ability dimension of metacognitive or self-reflective capacity. Also, they perceived the free inquiry experience in the form of ABC-DEF as helpful to understand the nature of scientists' scientific activities. Based on these findings, implications for supporting authentic inquiry in school science are discussed.

The purpose of this study is to develop scientist vignettes and to explore their effects to change students' perceptions of scientists, scientific attitudes, and the nature of science. The scientist vignettes developed in this study include research cases on seven scientists, including British zoologist Jane Goodall. Each vignette consists of 4 to 6 pages in consideration of the reading level of elementary school students, and contains illustrations describing the main contents of the text. In addition, scientist vignettes contain descriptions on terms and text boxes explaining the higher concepts, and each vignette contains questions that students can think deeply based on the story of the scientist. To verify the educational effectiveness of scientist vignettes, we investigated changes in their perceptions of scientists, scientific attitudes, and the nature of science in 564 elementary school students. We conducted group interviews with four elementary school teachers. As a result of conducting pre-test and post-test using a narrative questionnaire consisting of 6 questions, students became more sophisticated in the understanding of the science and the characteristics of scientists after experiencing scientist vignettes and their understanding the nature of science changed into a more modern epistemological perspective. Also, in a group interview with teachers, teachers assessed that scientist vignettes would positively affect the understanding of science process skills and the nature of science, and forming a scientific attitude, especially in increasing understanding of the nature of science. We discussed ways to effectively utilize scientist vignettes in elementary school science education based on these result.

The purposes of this study was to analyze qualitatively changes in students' experience and perceptions in relation to studying science using portfolios and any resultant effects on the portfolio itself. Five fourth-grade elementary students from one small city participated in this study. Data was collected through interviews as well as through student portfolios containing the science content matter of two units over two weeks. Observational diaries recorded by a teacher were also used to test the reliability of data collection. All interviews with students were transcribed to develop a suitable network to categorize students' responses. Students' portfolios were analyzed in order to reveal their essential characteristics in combination with their teacher's observational diaries. The results were as follows. First, student perceptions of their portfolios were categorized into three different levels; superficial, extended, and moderate perceptions. The changes in perception could also be divided into three levels; consistent-superficial, unstable, and a progressive-extended pattern. Second, the experience of students with their portfolio were investigated in terms of the following; successfully completing the elements of the portfolio, development of evidence, interaction with peers, teachers, and parents, and the standards of evaluation used for the portfolios. Third, the perceptions and experience of working on the portfolio by students had a number of direct effects on the way in which students actually created and developed their portfolios. Finally, students with positive attitudes towards their portfolios actively participated in the portfolio experience and finally understood what it meant completely. However, students with negative attitudes regarding portfolio based work, did not leave the experience with any heightened awareness of the utility or indeed, purpose of portfolio based work.
