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.

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 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.
