this study, the teaching methods of three science teachers for lead-iodide precipitation reaction experiment were compared. The difference of 9th grade students' understanding was searched according to the science teachers teaching styles, also. Among the three teachers, Teacher A taught students based on the science textbook and allowed students to think themselves and to get out conclusion by the experiment. Teacher B and Teacher C gave students a lot of explanations related to interpretation of the experiment. The percentage of no response on the experiment report of Teacher A was higher than those of Teacher B and Teacher C. But the students of Teacher B and Teacher C tended to have limited thoughts because of the teachers explanations. In spite of the difference, it was common phenomenon that few students understood concepts through the experiment. A lot of students were interested in the experiment, but it was hard to understand Law of definite proportions according to the experiment.

The purpose of this study was to research the effects of students' evaluation results on teachers' teaching activities. The subjects were 431 elementary school students of 4th, 5th and 6th grade, and 14 teachers of 7 schools located in Seoul, Cheongju, and Daejeon city. The experimental design included pre and post-tests with the control group. Our results found that most of the students had positive thoughts towards science classes. In particular, activities where the teachers provided support in the conduct of experiments and the learning atmosphere generally were evaluated higher than other activities. However, unrestricted experiments were evaluated lower by the students. The feedback from the students' evaluation results of their teachers affected the teachers' teaching activities statistically. The teachers' support during experiments, unrestricted activity during experiments, and evaluation activities were changed positively following the students' feedback. However, the loaming atmosphere and unrestricted activity during experiments were observed to change negatively when the teachers were not given the students' feedback.

This study is to recognize importance of casing anxiety on mathematics for underachievers and to examine a plan to solve a problem with anxiety, by analyzing factors which make underachievers anxious on the mathematics. First, we analyze factors which make mathematical underachievers anxious on the mathematics. Second, we compare and analyze a level of anxiety on the mathematics and factors which cause anxiety on the mathematics according to their grade and gender. This study's participants were 308 mathematical underachievers at 4th, 5th, and 6th grade, studying at six different elementary schools in three different areas. The results of factors which make mathematical underachievers anxious on the mathematics obtained from the survey are as follows. First, in the top-category factor, mathematical underachievers are influenced by following factors in order, which are a mathematic subject, learner's attitude, environment, and a teacher. Second, in the factor of making students anxious on the mathematics according tn their grade, although the mathematic anxiety of students at 6th grade is higher than students at 4th and 5th grade, in the anxiety differences between the different grades. Third, in the factors which make the students anxious on the mathematics according to their gender, female students show more anxiety than male students. In summary, an anxiety of the underachievers at the elementary schools are different in the top and sub-category factor, according to their grades and their gender. It is shown that the underachievers feel more anxiety compared to normal elementary schools, and therefore the anxiety on the mathematics is one of the causes of under-achievement of the mathematics.

Purpose : This study is descriptive correlation research to provide basic materials for developing program which can give practical assistance in preventing and managing obesity through more comprehensive approaches of influential factors on obesity found in existing literatures. Methods : Data were collected from the 4th, 5th and 6th graders at 2 elementary schools in Gwangju Metropolitan City and 4 elementary schools in Jeollanamdo province using questionnaire and students' physical examination results from June 15 to July 27, 2006 and data obtained from 1,866 students were used for analysis. Data collected were analyzed with technical statistics and correlation analysis using SPSS/PC(version 12.0). Results : 1. Obesity level of elementary school students was examined as follows; 33.2% had low weight, 44.3% normal, 10.8% overweight and 11.7% obese. 14.8% of boys and 8.6% of girls, 13.5% of the 4th graders, 12.1% of the 5th graders and 9.2% of the 6th graders, and 13.7% of urban students and 9.6% of rural students were obese. 2. According to general characteristics and obesity of the subjects, there were significant differences by sex(${\chi}^2=29.55$, p= .000), grade(${\chi}^2=12.84$, p= .046), region(${\chi}^2=41.96$, p= .000) and pocket money(${\chi}^2=33.43$, p= .001). 3. As genetic factors, all variables including sibling's obesity r= .128(p= .000), mother's obesity r= .098(p= .000) and father's obesity r= .081(p= .001) had influence on children's obesity. 4. Concerning environmental factors, there was positive correlation between eating habits r=- .052(p= .02) and school record r=- .048(p= .04) and there was negative correlation between internet using time r= .050(p= .03) and conflict with parents r= .048(p= .04). 5. Self-respect as psychological factor had negative correlation as r=- .048(p= .04). Conclusion : Consequently, the influential factors on obesity of elementary school students were as follows. Obesity was higher in boys than in girls, in urban areas than in rural areas, in lower grade than in higher grade, in children with obese siblings, obese father and mother, irregular and wrong eating habits, frequent internet uses, parents in conflict and lower school record and self-respect. Therefore, since it was found that these variables were more exact causes to increase children's obesity, development of various obesity mediation programs considering these variables at home, school and society is urgently required.

The educational effect of movie is very high. This paper suggests a practical scheme applying multimedia materials to some subject classes. At present film education consists of 3 methods, integrated method, regular method, and professional method in the 7th curriculum. The simplest method is integrated method. Most previous researches tried to apply to middle or high schools, or only one subject class. So we apply integrated method into 5th grade elementary students. At first teaching schedule is constructed on Korean, Social, Science, Ethics, and Art classes, and then movie materials are applied. Finally we let students write study book. Study book says that students take great interest and can promote the thought ability.

In order to study the effect of the 'General Science' course implemented under the 6th science curriculum, high school students' views about the relationship between science/technology and society and their perceptions of science classroom environment were investigated. Four classes (n = 211) were selected from those completed the 'Science I' course under the 5th science curriculum, and 4 another classes (n = 216) which took the 'General Science' course under the 6th science curriculum were selected. In order to compare students' views about the relationship between science /technology and society. 10 items were selected from the VOSTS (Views On Science-Technology-Society) while considering the 6th science curriculum and the 'General Science' textbooks, and administered at the end of the 'Science I' course and at the beginning and end of the 'General Science' course. In order to compare the perceptions of science classroom environment, the Perceptions of Science Classroom Environment Questionnaire, which was prepared from the Individualized Classroom Environment Questionnaire. the Science Laboratory Environment Inventory, and the Classroom Environment Scale. was also administered at the end of the 'Science I' course and the 'General Science' course. The results indicated that the mean VOSTS score of the 6th-curriculum group was lower than that of the 5th-curriculum group, although the difference was not statistically significant. The decrease in the VOSTS score of the 6th-curriculum group during the 'General Science' course was statistically significant. It was also found that unrealistic views such as 'technology is the application of science', and 'corporations should control science/technology' had been formed during the course. However, the 6th-curriculum group had more positive perceptions of science classroom environment. Educational implications are discussed.

This study was conducted in order to investigate the effect of students' attitudes to internet media language and orthographic knowledge on their use of internet media language. The participants were 989 students in the 4th to 11th grades in Kyunggi-do. It was found that the participants used more internet media language in internet literacy than for general writing. Elementary students exhibited significantly less orthographic knowledge and used more internet media language to write on the internet than older students. Students' attitudes to internet media language went a long way to explaining their self-assessment on the frequency of using internet media language and their genuine use of internet media language on the internet. Their orthographic knowledge, however, was not a significant predictor for their use of internet media language.
