This study analyzed the effects of 'app-based learning of observing and recording living things' on elementary school students' science-related attitudes. Samples of the study were composed of 24 sixth-grade students attending the science club of N elementary school in Seoul, Korea. The learning was conducted for 12 times over 7 months. 'TOSRA(Test of science-related attitude)' was used to quantitatively analyze the science-related attitudes of elementary school students. To find out more detailed characteristics, records of interview were also gathered and analyzed. The main results of this study are as follows. First, for the paired t-test of science-related attitudes, a statistically significant difference between the pre and post was found. As results of the interview, it was revealed that 'experiences of outdoor activities' greatly influenced the increase of science-related attitudes of the students. Second, in ANCOVA, according to 'gender' there was no statistically significant difference in score of science-related attitudes. But, there was statistically significant difference in science-related attitudes according to 'preferred science subjects' and 'whether individual interest has occurred about observing and recording living'. Based on the results of this study, implications for research of elementary biology education are discussed.

The goal of this study is to examine the sociality and school adjustment of elementary school lower-class students. The following research hypotheses were set up and addressed: Hypothesis 1: There would be significant differences in sociality of the elementary school lower-class students according to activity - making friends group counseling Program. Hypothesis 2: There would be significant differences in school adjustment of the elementary school lower-class students according to activity - making friends group counseling Program. The subjects for the study were 20 first grade students attending N elementary school in Daejeon area. The students were assigned to the two groups-experimental group(N=10) and controlled group(N=10). The experimental group received 10 sessions of the activity - making Friends group counseling program for 40 minutes by 2 times every week, and the controlled group didn't do anything. To verify the hypotheses, two tests(sociality and school adjustment tests) were administered for the pretest and post-test. Means and standard deviations obtained from these tests were analyzed with factorial covariance test using SPSSWIN(10.0). The results were as follows: Hypothesis 1 was confirmed. The scores of experimental group were significantly higher than those of controlled group in sociability, cooperation and independence, but not in observance. Hypothesis 2 was confirmed. The scores of experimental group were significantly higher than those of controlled group in teacher-student relationship, student-student relationship and classes, but not in the keeping rules. The conclusion of the result is that the program have a good effect on the elementary school lower-class students' sociality and school adjustment. Above all, along with long-term adaptability of the research, continuous studies are required.

This study analyzed the attributes of the conceptions of $3^{rd}$ to $6^{th}$ grade elementary school students on three states of matter and investigated the characteristics of the classified results of various examples of matter by grades. Through discussion activities, we confirmed the stabilization of conception attributions. For this study, 113 participants from two $3^{rd}$ to $6^{th}$ grade elementary school classes were selected. The concentration analysis (C-factor) and normalized gain (G-factor) of the conceptions for the quantitative analysis of the conception changes were used. The elementary school students retained different percentages of the attributes for states of matter. The characteristic of the grades were different between the 3rd grade and other grades. Based on these results, we pointed out the problems with the present teaching methods in science textbooks and stated the advantages of the effects of the representation of mixtures.

The purpose of this study is to understand the public education system in Korea, that features many pre-taught students, and to figure out how elementary school teachers teach them. To accomplish this study, 204 elementary school teachers in Seoul participated in a survey and the frequency and percentage were made. In addition, to add more depth to this study 5 elementary school teachers had several interviews. We obtained the following results. First, elementary school teachers generally think that the situation with many pre-taught students have had a bad effect on public education and pre-taught students are drilled but cannot understand what they have learnt. They also answered that they have low morale when teaching pre-taught students. Second, a large number of elementary school teachers think the situation with many of the pre-taught students does not help the public math education system, which influences the teachers' teaching style. Teachers who answered negative on pre-taught students are running their math classes focusing on understanding math concepts and activities. On the other hand, few teachers who answered positive on pre-taught students did not care about the situation with many pre-taught students.

In this study, we investigated preservice elementary school teachers' awareness of students' misconceptions about several science topics, and the variables influencing their awareness. Seniors (N=106) from an university of education were asked to predict elementary school students' misconceptions on science topics such as phase changes and dissolution. Their conceptions about teaching and learning were also measured. The results indicated that the preservice teachers' predictions about the kinds and/or the ratios of students' misconceptions were different from those reported in previous studies. The low level preservice teachers in terms of the degrees of possessing traditional conception about teaching and learning predicted more students' common misconceptions. The degrees of preservice teachers' constructivist conception about teaching and learning and their major, however, did not significantly influence the numbers of common misconceptions predicted.

The objective of this study was to investigate the effect of occasional mid-morning snacks (MMS) on dietary behaviors and school life among elementary students. The students, mothers, and teachers from two elementary schools in Seoul were selected. The schools have been provided a steamed sweet-potato or potato, or a piece of rice-cake or cake with a pack of milk as MMS 3-4 times a month for more than 3 years. Most students were satisfied with the MMS. Mothers and teachers reported that their children or students were happier, more active, and more energetic in school with MMS. Furthermore, the students answered that they could drink milk better on the day when the school provided MMS. Many students felt that it was relevant to serve a simple menu at lunch time if they were served MMS. Also, students became more interested in school meals or foods with MMS. In addition, mothers who had jobs wanted more frequent MMS. The degree of satisfaction about MMS of the teachers was higher than that of students or mothers. Many teachers thought that their students drank milk better with MMS and further, that it made students to drink more milk on other days. In conclusion, MMS had positive effects on the dietary behavior and school life of elementary students. Therefore, it can be a good option for eliminating skipping breakfast because it provides more nutrition, makes students drink more milk, and allows students to enjoy school activities more.

The purpose of this study was to develop a risk communication material on artificial food color additives for elementary school students. The development was based on a previous study on the perception and information needs of elementary school students on artificial food colors including that the students usually were interested in artificial food colors, but didn't know about those well, and they wanted to get information on the safety of their intake, function and necessity of food color additives. Based on the above results, a comic book on artificial food colors was developed as a risk communication material for the elementary school students by brainstorming and consultation with experts. The book was titled as 'Variegated artificial food colors! Understanding and Eating'. It contained basic information on food additives focused on artificial food colors including definition, function, calculation of ADI, usage of artificial food colors, quizzes and useful web sites, etc. The results of field evaluation for the developed material by 101 elementary school students were very positive in getting the correct information, understanding artificial food colors and having proper attitude for healthy dietary life. Therefore, the developed material could be used to help elementary school students have proper perception on artificial food colors and facilitate the risk communication on food additives.

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 research aimed to obtain basic data for elementary school students to form proper concepts by comparing the science gifted students and the ordinary students of elementary school with regard to the groundwater concept, formation process, existence forms, and movement. The research subjects were 65 fifth and sixth graders of the elementary school students and the spatial ability test was conducted on the subjects, and 4 science gifted students and 8 ordinary students chosen from the subjects were analyzed using half-structured interview data and ground water drawing drawn by the students. The conclusion derived in accordance with the research purpose is summarized as follows. It was found that there were no great differences in the answers to the question asking what groundwater is between the science gifted elementary school students with high spatial ability and the ordinary elementary school students with moderate spatial ability. The ordinary students with low spatial ability tended to regard groundwater as the concept of water and sewage. In the concept of the formation process of groundwater, the science gifted elementary school students with high spatial ability explained it by citing diverse surface water such as rainfall, river water, lake, and waterfall, and the ordinary elementary school students with moderate spatial ability all mentioned only rainfall and river water and could not explain diverse spatial factors. The ordinary elementary school students with low spatial ability mentioned rainfall and river water and perceived that groundwater was formed artificially. In the concept regarding the existence form of groundwater, the ordinary elementary school students with low spatial ability could not think of space perception that small pore space exists in earth or soil in the ground. The science gifted elementary school students with high spatial ability knew that groundwater exists in pore space with regarding groundwater movement, the ordinary elementary school students with low spatial ability thought that there was no groundwater movement and that it could be moved only by artificial facilities. There were differences in the perception of pore space and in the perception of existence and non-existence of groundwater movement accordingly, but for most of the elementary school students, the concept of groundwater was formed differently from the scientific concept. It is considered that most of the elementary school students formed erroneous concept about groundwater and could not connect ground water under the surface of the earth with the substances forming its surroundings with regard to the concept of groundwater.
