This research investigated the eating out and snack intakes situation of five hundred eighty five $5^{th}\;and\;6^{th}$ graders living in the city and rural parts of Jeonbuk province. The results of this study are as followed: Nuclear families in urban area and rural community are 84.5% and 64.7% respectively. On the other hand, extended families are 7.9% in urban area and 18% in rural communities. Out of all the households, 34.3% (urban: 37.2%, rural community: 31.5%) answered they like to eat out. Over 50.3% preferred eating Korean style food and the reason was 'the taste': urban (71.4%) and rural community (67.8%). People living in urban communities seemed to eat out more frequently than rural places and $3{\sim}4$ times a month was the average. Usually people seemed to eat out during the weekends and in the evening time 84.3% (after 7:00 p.m.). Based on each family's living standard, people answered 'we hardly ever eat out' for those in the lower class (59.1%), the middle class said once or twice a week (47.1%), and the upper class (35.7%). It was obvious that people in the middle and upper class tend to eat out more frequently than those in the lower class. The most common period of time which snacks were taken was after school (38.5%), on the way back from educational institute (35.0%) and the choices of snacks which they purchased were frozen sweets (56.4%)chips & cookies (25.2%) beverages (9.9%) Fast foods (4.6%) and fried foods (3.9%) in order. Urban children seem to eat more frozen sweets and rural children ate more chips & cookies. Also, amount of snacks between meals showed a higher percentage to those who had more pocket money, The type of snacks were fruits (37.1%) chips and cookies et cetera (19.2%) instant foods (12.8%) dairy products (11.1%) confectionary (10.3%) fried foods (5.1%) in order. The result shows that urban children eat out more frequently than those in rural areas, Eating around 7:00 p.m. was most common and the middle and upper class tend to eat out more frequently than those in the lower class, Also, snacks were most often bought before and after school. After 10:00 p.m frozen goods and chips were the most preferred choice. Specially, the reason for eating fast foods was because of the pleasing taste. From this study, it is clear that eating out and having snacks became pervasive into our lives in both urban and rural areas. Hereafter, an appropriate eating habit should be correctly educated to elementary students by spoken words and textbooks in a curriculum. In reality, snacks are classified as being the leading factor of obesity. Therefore more products containing balanced nutrition should newly develop rather than snacks with high fat content.

The purpose of this research was to examine the problems, confidence and satisfaction of teachers on the subject ${\ulcorner}technology and home economics{\lrcorner}$ in the 7th national curriculm. For this research, questionnaires were sent by post to teachers who teach technology and home economics in middle schools and high schools. The collected questionnaires were technically analyzed by SPSS/WIN 10.0 program, which measured frequency, percentage, average, standard deviation. According to the types of data, they were also analyzed by t-test and cross tabulation analyses. The results of this research were summarized as follows. 1) There were two teaching types of technology and home economics: the partial charge and the whole charge teaching according to teachers' majors, and both types occurred in similar percentage. The partial charge teaching means that teachers majoring in technology teach only the technology part and teachers majoring in home economics teach only the home economics part when they teach the same subject, technology and home economics. These days the partial charge teaching more often occurs in national or public schools than in private schools, and in coeducational schools than in girls' or boys' schools. 2) The major problems of teaching technology and home economics were caused in order by teachers' lack of skills and knowledge which we not their own major, the lack of students' interests and teaching materials, and burden of tests. 3) Teachers' confidence in teaching the contents of the subject, technology and home economics, made a significant difference according to their majors. Teachers whose major was technology felt more confident when they taught the chapters of the textbooks related to their major, technology, while teachers whose major was home economics felt more confident when they taught the chapters of the textbooks related to their major, home economics. According to implementation types, the partial charge teaching gave higher confidence to the teachers than the whole charge one in teaching almost all the chapters of the textbook. 4) According to implementation types, teachers' satisfaction was showed to be higher in the partial charge teaching than in the whole charge one.

The purpose for this study is to inquire into the effects of teaching methods in the class on the conceptual change of atmospheric pressure for middle school students. After analyzing the concept of atmospheric pressure in the middle school science textbooks on the present 7th Curriculum, classes were performed adopting classified Method A and Method B. For Method A, the textbook used that explains the concept in the view of weight. For Method B, the textbook used approaching to the concept in the views of molecular movement as well as of weight. This study consists of four classes in the third grade students of middle school in Busan, which were divided into the Method A group and the Method B group. The result of the study carried out pre-post each of these classes on the learning achievement and on the conceptual change of atmospheric pressure. The result of this study were as follows: First, the effect on the learning achievement was displayed the average score of the Method B was showing meaningful difference comparing to the Method A. Second, the effect on the conceptual change measured by verifying the score for the difference among the averages for each sub-scale three out of four conceptual factors, 'the direction of atmospheric influence and the reason', 'the principle of atmospheric action' and 'the atmospheric changes by the temperature rise on the surface of the earth and the reason', showed meaningful improvement. But, the one left factor, 'the distribution of atmospheric pressure by altitudes and the reason', displayed no meaningful difference. Third, The concept of atmospheric pressure is better defined as the pressure created by the movement of air particles, in the view of kinetic theory of gas, rather than explained by the notion of the weight of air.

The purpose of this study was to analyze the contents and designs of the developed 22 teaching and programs for the gifted students in elementary mathematics. The focus of the analysis were the participants and the characteristics of the contents, and were to reflect them on the areas of the 7th elementary mathematics curriculum and Renzulli's Enrichment Triad Model. The results of the study as follows: First, the programs for the low grade gifted students are very few compared to those of the high grade students. For earlier development of the young gifted students, we need to develop more programs for the young gifted students. Second, there are many programs in the area of geometry, whereas few programs are developed in the area of measurement. We need to develop programs in the various areas such as measurement, probability and statistics, and patterns and representations. Third, most programs do not follow the steps of the Renzulli's Enrichment Triad Model, and the frequency of appearance of the steps are the 1st, 2nd, and 3rd enrichments, sequentially. We need to develop hierarchical programs in which the sequency and relations are well orchestrated. Fourth, the frequency of appearance is as follows as sequentially: types of exploration of topics, creative problem solving, using materials, project types, and types of games and puzzles. In the development of structure of the program, the following factors should be considered: name of the chapter, overview of the chapter, objectives, contents by steps, evaluation, reading materials, and extra materials.

Korean 7th national curriculum gave the right to elect the advanced subject such as physics II, chemistry II. Students could elect the subject by their aptitude and interest. But, actually, the choice was constrained by school circumstances such as the number of teacher and the number of class. high school students. We investigated the demand about school science and perception about scientifically specialized high school in which the students could have all advanced science subjects by the survey of 336 middle school students including 148 students in the science education center for the gifted, 220 high school students, and 70 science teachers in capital region. As results of this study, most of the high school opened chemistry and biology advanced subjects, but only 37.1% of them opend physics advanced subject. This constrained students' right of elect the subject by their interest. While most of middle school and high school students normally demanded the more experiment in the class and the easier science content, the students in the science education center for the gifted demanded more science class time. The students who wanted to have science career had very positive recognition of scientifically specialized high school and science teachers agreed to running the scientifically specialized high school.

Mathematics anxiety is likely to be a drag on mathematics learning if that is left alone, and it is important to grasp the cause of mathematics anxiety and devise how to get rid of it. The purpose of this study was to examine the cause of mathematics anxiety among elementary school children, to develop a math-friendly activity program geared toward easing mathematics anxiety and to check the effect of the developed program on the alleviation of mathematics anxiety. The subjects in this study were 32 students in a fourth-grade class in I elementary school located in Dongdaemoon-gu, Seoul. A math-friendly activity program was designed to alleviate the mathematics anxiety of the five subfactors-test anxiety, time constraints, comprehension, learning motivation and parent attitude-on which the students scored higher than their pretest collective averages. The mathematics anxiety pretest data, the objectives and content system of the current 7th national mathematics curriculum and the mathematics textbooks for 4-A and 4-B were analyzed to develop the math-friendly activity program that consisted of psychological remedy (positive thinking training) and non-psychological remedy (mathematics activities). After the program was implemented, we analyze the pretest and posttest mathematics anxiety data to determine the effect of the program. As a result, the collective averages of every student on math anxiety and its subfactors were lower in the posttest than in the pretest.

The purpose of this study was to examine the effect of instruction for the development of analytical rubrics based on teacher-student compromise, which would be applied to performance assessment about the ninth-grade housing unit of the 7th national curriculum. In order to find out the influence of the rubric development instruction on learning motivation, two different third-year classes in a middle school were selected respectively as an experimental group and a control group. The way of presenting the rubrics and learning motivation were respectively selected as independent and dependent variables. Both groups took two lessons and a pretest-posttest on learning motivation. As for the analytic rubric for the individual task performance in the housing unit, three evaluation items were selected. As a result, the instruction for the learner-involved development of analytical rubrics for the housing segment had a positive effect on the confidence and satisfaction of the middle schoolers, which were two out of four sub-factors of learning motivation. Open-ended questions showed that the instruction got to build confidence in the course of being aware of the evaluation criteria and fulfilling the given tasks.
