  • The purpose of this study was to investigate the recognition of middle school students on 'Thinking Science' activities and the influence on the understanding of the gas particles behavior concepts. For this study 125 students of four classes first grade in middle school were divided into two groups, the experimental and the control group. The SRT II test was carried out to identify the cognitive level of the students. The logical factors, needed to understand of the gas particles behavior concepts, were extracted. And the 9 'Thinking Science' activities designed to develop these factors were chosen and then implemented to the students of the experimental group. After the lesson for the gas particles behaviors, the achievement test of understanding of the gas particles behavior concepts and the survey of the students' recognition on 'Thinking Science' activities were administered. According to the results of the achievement test, there was not significant difference between the two groups on the whole. But only mature concrete operational students in the experimental group got high scores than those in the control group in analyzing the effect size. According to the results of the ANCOVA analysis, there was significant difference between the two girls' group. When students in the experimental group had a positive perceptions about 'Thinking Science' activities, they got higher achievement scores. This implied that there was a correlation between perception about 'Thinking Science' activities and their achievement in the gas particles behavior concepts. Especially, students with positive perception in mature concrete operational period got higher scores in science achievement. After the 'Thinking Science' activities, there was a high perceptions about improving in scientific thinking.

  • This study researches an obesity index and the realities of physical activity of elementary school children and provide basic data to instruct correct physical activity for low weight and obese children. The subject was 813 Elementary School Children of grade 4-6 in Kyungju and data were collected with a Physical Activity Questionnaire from YHS, USA. The collected data were analyzed with real number, percentage, average and standard deviation techniques. The range was by SPSS WIN. Both of them were in the normal range, between -38.3 and 77.7, between low weight and obesity. The results are as follows : 1. An Obesity index according to grade and sex: the average obesity index of 423 boys was $7.56{\pm}15.7$, for girls it was $2.56{\pm}14.3$. Both of them were in the normal range, between -38.3 and 77.7. There were low weight($-38.85{\pm}0.9$) students as well as obese, including extremely low weight children ($-38.85{\pm}0.9$) and extremely obese children. 2. On the whole, in the Frequency of the 25 item physical activities breakdown, children reported to watch TV 1. ($2.7{\pm}0.6$), or do homework($2.1{\pm}0.9$), more than three-fourths of the week, male children, however, played more football($2.0{\pm}0.9$). As male obese children do less MET5, MET8(highly active activity) than male normal children, it was also discovered that low weight children do more severe activity in MET8(high activity). In female cases, it was revealed that neither do highly intense activity. 3. In physical activity, male children received higher points than female children with $92.94{\pm}37.95$ to $74.46{\pm}29.50$. On the whole, male and female obese children had lower score than normal children. 4. As for attitude toward physical activity, male children($31.96{\pm}4.37$) had a positive attitude than female children ($29.57{\pm}3.89$), but obese male children had a negative attitude regarding activity viewed as normal. Therefore, in preventing obesity in elementary school children the treating of under-weight children should be included in the obesity program so as to prevent mal-nutrition or deficiency. It is needed to instruct obese children to carry out intensive work-outs at least 3 times a week through systematic programs. It is also needed that parents and teachers educate elementary school children from an early age with information on the frequency and intensity of work-outs to prevent obesity. It is also desirable that children be educated to carry out physical activities that address their specific needs. As a result of this study, obesity management must be started from elementary school and children should be instructed to act in high-intensity actirities when they spend leisure time.

  • This study investigated the perception of pre - service teachers in order to find out how paper textbooks are used in high school classes and what improvement is needed. Firstly, the results of analyzing the perception about the utilization of textbooks are as follows. First, in the case of Korean language, social studies, mathematics, science, and English, textbooks were used most frequently, and most of the respondents did not use textbooks for arts and physical education subjects. Secondly, Korean language, social studies, mathematics, science, and English textbooks are most frequently used as teaching materials. Third, in the case of Korean, social, mathematics, science, and English subjects, in addition to textbooks, problem collections were used most frequently and arts and physical education subjects showed the most use of prints. Next, the results of analyzing the perception of the improvement method of the textbooks are as follows. First, in the high school class, the response rate was high in that Korean, social, mathematics, science, and English classes needed a textbook. Most of the respondents answered that they were not necessary for the textbooks of arts and physical education subjects. Second, in order to improve the textbooks, the most demanding textbooks focused on the core basic contents, followed by self - directed learning activities, competency centered contents selection, cooperative learning activities, and teacher self - development. The demand for digital textbooks was low.

  • In this study, we studied some examples using GSP(Geometer's SketchPad) in the process of problem solving that is explained by G. polya. After reconsidering examples, we tried to show that using GSP can help student's intuitive thinking, investigative activities, reflective thinking. Especially, in the three phase of problem solving(understanding the problem, devising a plan, looking back), mathematics teachers may using GSP in order to helping student's understanding. Besides, we tried to suggest the direction to use GSP more adequately in the teaching and Beaming mathematics. First of all, Mathematics teachers using GSP in their class must have ideas how to use it. And they have to be careful on the didactical transposition of mathematical knowledge in the computer-based learning. They also have to lead students move from activities with GSP materials to carrying out the problem solving plan and reflection activities.

  • Two hundred and sixty-six mothers with preschool and primary school children filled out TV diaries for three days around the TV turning-off campaign day initiated by YMCA. TV diaries were designed to record the TV programs watched by family members as well as the focused child's activities every 15 min. 121 families participated in the campaign voluntarily and 145 families served as the control group. The campaign group watched less than the control group even before the campaign day and differed in several family backgrounds primarily due to the difference of family members' ages in both groups. Despite participating in the campaign, 53.9% of the families among the campaign group watched TV and 35.5% of the children in these families watched TV on the campaign day. TV watching time measured by the questionnaire was significantly higher than the estimates by diary method. Participating children in the campaign increased in activities such as reading, indoor play, as well as video watching. In the campaign group, TV watching time on the next day of the campaign increased slightly than the day before it. Preschool and primary school children's activities as well as the watched TV programs were analyzed separately for two groups. In addition, total TV on-time and coviewing patterns by the focused child with the family members were analyzed in relation to the child's other TV watching patterns as well as their related variables.

  • The purpose of this study is to find out how SNS marketing activities affect brand recognition, brand familiarity, and purchase intention for consumers who have purchased products from franchise chicken stores, including whether there is a moderating effect according to gender. SNS marketing activities were set up by configuring three attributes which are, SNS advertising, SNS information, and SNS events as sub-factors. For empirical analysis, a survey was conducted on SNS users, and SPSS/AMOS statistical programs were employed for the data analysis. First, the result of the empirical analysis showed that SNS advertising, SNS information, and SNS events have a significant positive effect on brand recognition. Second, it was found that the SNS events had a significant positive effect on brand familiarity. Third, it was found that SNS advertising has a significant positive effect on purchase intention. Fourth, it was observed that brand recognition has a significant positive effect on brand familiarity. Fifth, it was found that brand recognition and brand familiarity have a significant positive effect on purchase intention. Sixth, it was found that gender plays a significant role in the relationship between these constructs. Therefore, it can be assumed that the hypothesis presented in this study is sufficiently proven.
