In this study the effects of science teaming with the level of inquiry requirement in elementary school science experiment instruction were investigated on cognitive domain. We assigned seventy-three students of the fifth grade into two groups according to the levels of inquiry requirement. After each instruction was implemented, the characteristics of the students' tearning science on cognitive domain were compared and analyzed with the levels of them. The higher level (HL) inquiry-required instruction was more effective in increasing and maintaining the memory on the science teaming than the lower level (LL). Especially, in the aspects of the experimental methods and taking cares which the students engage and perform actively rather than do passively, the memory scores of HL group were higher than those of LL. In addition, the memory scores and the degree of maintenance were higher among students who perceived the instruction as easy and interesting. In conclusion, the HL of instruction could stimulate the students to challenge the problems, thereby make them construct meaning actively and improve the amount and degree of maintenance of memory on science teaming.

The purpose of this study was to investigate the mediating effects of self-regulation abilities on the relationships between parental attachment, peer attachment, teacher attachment and children's happiness in elementary school students in higher grades. The subjects of this study were selected from 4th-6th grade students residing in Dae-gu and Kyung-buk using questionnaires from May 1st to July 1st in 2014. The statistical analysis program(SPSS) was used for analyzing the collected data from the research in correlation analysis. To examine the mediating effects of self-regulation abilities on the relationship between parental attachment, peer attachment and teacher attachment and children's happiness, the Baron and Kenny(1986) model was used.. The results are as follows. First, in the case of father attachment, mother attachment, peer attachment, and teacher attachment, self-regulation abilities and children's happiness, as perceived by higher grade elementary school children positive correlations were observed. Second, in terms of relative effects of father attachment, mother attachment, peer attachment and teacher attachment on children's happiness, mother attachment was observed to have the most effect on children's happiness. Third, self-regulation abilities, as perceived by the children, mediated the effect of father attachment, mother attachment, peer attachment, and teacher attachment amongst higher grade elementary school students and the subsequent affect on children's happiness.

The purpose of this research was to investigate the effect of using digital science textbook on the scientific problem solving of elementary school students. For this research, an instrument to measure student's problem-solving skills was developed. The pretest and posttest scores of one hundred and six 5th grade students' problem-solving skills were analyzed and also the responses of three students who were selected by their levels in the problem-solving science digital textbook class were qualitatively analyzed. The results of this study were as follows; the scores of problem solving skills of science digital textbook groups were higher than that of traditional paper textbook group(p<.05). In the qualitative analysis of the students' reponses in a digital textbook class according to their achievement level, low-achievers' problem-solving skills were much more improved than high- and mid-achievers' skills. In conclusion, science digital textbook has a potential to improve students' scientific problem solving skills, and this possibility will be much higher when science digital textbook is used with teachers' intended instructional goals and strategies like problem-solving lessons.

The purpose of this study was to investigate effects of discussion using newspapers on fifth grade elementary school students' academic achievement and affective characteristics related to science. Additionally, this study intended to examine students' ideas about newspaper utilization, discussion based learning and science with questionnaire. The subjects were 59 fifth grade students from two classes. NIE was used in the experimental group and traditional teaching methods in the control group. In pretest and posttest sessions, both groups were evaluated by the academic achievement test, and an affective characteristics related science test. The results of this study showed that the academic achievement of the experimental group which applied discussion using newspapers was significantly higher than that of the control group which applied traditional instruction, especially in terms of knowledge and understanding. Additionally, the results showed that discussion using newspapers had a positive effect on affective domains such as perception, interest and attendance for science classes. In particular, the post-results of the experimental group were higher than pre-results, on the other hand, those of the control group were lower than preresults in all affective domains. It appeared that students had positive thoughts about newspaper utilization, discussion based learning, and science. The half of students who had low academic achievement showed negative reactions for discussion based learning.

Purpose: This study is to examine the relationship between safety awareness and safety accident occurrence with elementary school students. Materials and methods: It selected 10 elementary schools under the supervision of Jeonnam Board of Education and sampled 700 students randomly from 2-3 classes in the 5th and the 6th grade. One preliminary survey was conducted to revise and complement the contents and forms of questionnaire with 70 students of a school from Apr. 1 to 6, 2004 and this study was conducted from Apr. 10 to 30, 2004. Total 700 questionnaires were distributed and 681 were collected (97%) and 602 were used for final analysis except 79 lacking responses. Data collected were analyzed with SPSS statistical program. Results: The average score of safety awareness of subjects by area was high as 2.72 points out of a possible 3. Area showing the highest safety awareness was safety from fire. Girl students had higher safety awareness than boy students. The fifth graders had higher safety awareness than the sixth graders. In safety awareness by the number of siblings, single son or single daughter showed the highest safety awareness. 53.2% of the subjects experienced accident for one year, the frequency of accident was mostly once and most of accidents were occurred at school. Accidents for the last year were higher in boy students, the sixth graders. According to relationship between safety awareness and safety accident, group with lower safety awareness in school safety(P < .022), traffic safety(P < .016), fire safety(P < .019), home safety(P < .007) and accident treatment and first aid(P < .003) had higher safety accidents than that with higher safety awareness. Conclusion: Development of safety education program by grade, that of parents safety education program, field experience and practice with students, teachers and parents and various safety education programs should be substantially and repeatedly accomplished for prevention education of safety accidents. In addition, to prevent and cope with safety accidents, safety education should be reflected on normal education, safety education textbook be developed, special safety education teachers be employed for safety education.
