The school foodservice was quantitatively extended by policy of government all the while. There was carried out the survey of customer satisfaction about school foodservice by the ministry of education, science, and technology since 2006 years. Therefore, the purpose of this study was to grasp an improvement of the scores of school foodservice' quality attributes and satisfaction as compared with the preceding year by respondents and school type (elementary school, middle school, and high school). An annual survey was practiced to respondents (students, parents, and faculty) on september 2007 years and 2008 years in 16 cities and provinces. The statistics was analyzed to descriptive analysis and t-test for SPSS 12.0. The scores of school foodservice' quality attributes and overall customer satisfaction were almost increased to students, parents, and faculty and especially, big elevation in middle school. There was big increased the quality attributes such as 'providing information on foodservice', 'pleasant foodservice environment', 'kindness offered by employee' in elementary school, middle school, and high school to total respondents. An overall satisfaction in school foodservice was improved from 69.2 score to 71.9 score. On students, scores of overall satisfaction was increased from 72.9 to 74.0 as students of elementary school and from 61.5 to 65.8 as students of middle school (p < .001). Therefore, for improvement and development of school foodservice, there should be a necessary for an operator of school foodservice and an office of education to make an effort.

Probability plays a very important role in modern society as an essential tool for solving various kinds of problems from our real life or scientific province. However, most of precedent studies on probability pointed out that many students had difficulties in understanding the nature of it, and that probability teaching method in the classroom is easily led only to calculation system, which is isolated from practical applications. In this paper, I make a close study further onto these themes, by analyzing the 8th grade textbooks through these following questions; how do the textbooks deal with calculation of probability that certain two events occur at the same time? On the practical basis, how do they make use of probability as a problem-solving instrument in both actual life and scientific fields? After these, I try to extract some features and issues of probability teaching method in current Korean textbooks.

Using the 3rd to the 6th wave data from the Korean Children and Youth Panel Survey(KCYPS), we examined the effects of academic characteristics and social relations on the trajectories of the life satisfaction among adolescents. OLS results showed that male students were more satisfied with their lives than female students in the 3rd grade of middle school. As academic characteristics, academic achievement and the level of class adjustment improved life satisfaction but the amount of learning time spent had a negative effect on life satisfaction. However, the effect of academic achievement lost its statistical significance after including variables of social relations. Relationships with parents, teachers, and friends had positive effects on life satisfaction. The longitudinal analysis using the fixed effect estimation also showed a similar result of the associations among the variables to that in the OLS analysis. The life satisfaction gap between male and female students narrowed over time from the 3rd grade of middle school to the 2nd grade of high school. The effects of relationships with parents and friends showed significant effects on both female and male students, but the relationship with their teachers was significant only for female students. Based on the results, we discussed the issues of Korean education related to the life satisfaction among adolescents.

The purposes of this study were to analyze problems in the experiments for comparing properties of a mixture with a compound of iron and sulfur and then to suggest the improved experiments. For this study, the experimental methods in 9th science textbooks described were analyzed and middle school science teachers were asked to conduct the experiment according to the process of the textbook and to point problems of the experiment. Two alternative experiments, which improves the problems of the toxic and provocative experiment and of distinction between a mixture and a compound by magnetic properties, were proposed. The two experiments were applied to the 10 science teachers and 60 students from a “S” middle school. They responded that the experiments were suitable for comparing properties of a mixture and a compound and helpful to understand the concept.

The purpose of this study was to examine and analyze the cognitive demand of the mathematical tasks suggested in the middle school textbooks. In particular, it aimed to reveal the overall picture of the level of cognitive demand of the mathematical tasks on function in the textbooks. We adopted the framework for mathematical task analysis suggested by Stein & Smith (1998) and analyzed the mathematical tasks accordingly. The findings from the analysis showed that 95 percent of the mathematical tasks were at low level and the rest at high level in terms of cognitive demand. Most of the mathematical tasks in the textbooks were algorithmic and focused on producing correct answers by using procedures. In particular, the high level tasks were presented at the end of each chapter or unit for wrap up rather than as key resources.

The purpose of the study was to investigate how to improve students' information literacy and problem solving abilities in the computer subject. A web-based problem-based learning (PBL) for computer subject for the 8th graders in middle school are designed and developed. In addition. the process of learners' problem solving on problems produced from PBL model was analysed 10 investigate the way how to evaluate learners' responses and products during two semester.

The purpose of this study was to investigate the effects of instruction applying 3D Planetarium Software (Starry Night Pro 6.0) in terms of the learners' science achievement, changes of attitude (attitude toward science as well as scientific attitude), and self-directed learning ability. Participants were 198 $8^{th}$ graders. This study adopted a quasi-experimental research design in which experimental group was taught with 3D planetarium software vs. control group with traditional lecture-centered teaching method for 6 hours. The effects were investigated by independent sample t-test and paired sample t-test The results are as follows. The instruction using 3D planetarium software was more effective than the traditional lecture-centered curriculum in science achievement and self-directed learning ability. However, there were not meaningful differences in analyzing attitudes related science, the results that were so effective in elevation for self-directed learning could be gained. Students were interested in instruction applying 3D planetarium software, which was helpful for them to understand the content knowledge. Results showed that instruction with 3D planetarium software applied was effective in $8^{th}$ grade science learning.

This study is basic research about actualizing mathematical teaching and learning based on storytelling that is raised for reforming school mathematics education. We have developed mathematics textbook model for 2nd grade in middle school based on storytelling. It was applied in the middle school classroom and the results were analyzed. In order to develop the mathematics textbook model, the procedures and methods of development were extracted from the literature. And mathematics textbook model was developed in accordance with the process and methods. To apply it in school 20 hours of instruction were carried out. For the analysis of the results, we conducted a questionnaire survey, the teachers' interview, the affective test and math anxiety test. Through the results of this study, we will be able to check the possibility of storytelling in mathematics class. And it will be also the foundation of mathematics teaching and learning based on storytelling in middle school.

Software developing education teaches students computer programming, which allows them to actively use IT and talk to computers. In this study, we analyzed computer science curriculum in the United Kingdom, the United States, India, and Estonia. In order to teach 1st - 9th grade students computer programming, we suggested the learning objectives, instructional design, and evaluation methods in software developing education focusing on Information Science. The objectives were divided into four phases, which were determined by age and grade level. Then, we determined 2-3 outcomes for each phase.
