The purpose of this study were to investigate middle and high school students' food habits and food attitudes, and to assess student's nutrient consumption. A self-administered questionnaire was developed based on review of literature. The questionnaire consisted of three sections (food habits, food attitudes, and food consumption). The questionnaires were distributed to 4,050 students enrolled in 34 middle and high schools located in Seoul, Gyeonggi, and Gyeongnam provinces. A final response rate was 88.2% (3,570) excluding responses that had significant missing data. Data of the food habits and food attitudes were analyzed with descriptive analysis, $x^2$-test, and t-test using SPSS WIN(ver.11.0). The student's self-reported food consumption data was converted into nutrient consumption using conversion factor. Many middle and high school students skipped breakfast and/or dinner. Approximately 29% of the students did not eat vegetables and fruits. Scores of the middle school student's attitudes(19.1) towards foods were significantly higher than those of the high school student's attitudes(18.7)(p<.001). Student's nutrient intakes were estimated according to the student's self-reported food consumption data. The nutrient intakes were compared with DRIs(Dietary Reference Intakes: DRIs) for their age groups. The result of EAR(Estimated Average Requirement: EAR) cut-point method demonstrated 57.7% of middle school boys, 64.4% of middle school girls, 70.2% of high school boys, and 71.0% of high school girls did not meet EAR for Calcium. Additionally, it showed that 39.0% of middle school boys, 23.7% of middle school girls, 58.4% of high school boys, and 24.4% of high school girls did not consume EAR for Vitamin $B_1$. 25.7% of middle school boys did not meet EAR for Vitamin $B_2$, while 44.4% high school boys did not satisfy EAR for Vitamin $B_2$.

It is desirable that the minimal standards of total collection is 5 books and 3 AV for a student in elementary schools, 7 books and 5 AV for a student in middle schools, 10 books and 7 AV for a student in high schools. 3. Annual growth is 0.5 for a student in elementary schools, 1 for a student in middle schools and 1.5 copy for a student in high schools. And, the number of minimal serials is 20 titles in elementary schools, 30 titles in middle schools and 50 tides in high schools. 4. Besides, basic collection, with the advances of technology, the school library collection should include new formats and delivery systems such as CD, video discs, videotex, computer software, satellite transmission etc. 5. The recommendable annual ratio of withdrawl is 3 to 5% for update and functional materials.

The purpose of this action research project was to study the effects of incorporating coding into the middle school math classroom affected student dispositions with math and their understanding of mathematical concepts. The project, involving a total of 107 US middle school students, used five data sources to examine these effects: a survey, a chart measuring student engagement, a pre- and post-assessment before and after the coding project, and teacher observation with reflection forms. After analyzing the data, it was found that incorporating coding into the middle school math classroom could have a positive impact on student math dispositions and their understanding of math concepts.

Conducted as an ethnographic examination of science teaching and learning in an Innovative Middle School in Korea, this study employs sociocultural theory to examine how structures afford and limit student participation in an innovative school designed to promote student-centered learning. Data includes teacher and student interviews, student responses to a questionnaire, classroom observations, and analysis of video recordings of ten lessons in two in two 8th grade science classes. Using structure|agency dialectic theory, we identify and describe some structures that afford and limit teacher and student agency at the micro (science classrooms), meso (school), and macro (Korean society) levels to raise some questions about current reform measures, such as innovation schools, that seek to position classroom teachers as agents for change in science education reform in Korea. Findings suggest that while teachers and school administrators play an essential role in structuring learning opportunities at the meso and micro levels, they have limited agency to address structural constraints originating at the macro-level, which can negatively impact teaching and learning in the science classroom. We offer implications for policy and practice and argue the need for more qualitative research, informed by sociocultural theory, to inform science education reform efforts in Korea.

In this paper we make an experiment in order to test whether the teaching method with the Zone of Proximal Development (ZPD) developed by Vygotsky can be more effective and well applied in the middle school pratces. Based on this investigation, we conclude that ZPD help to efficiently enhance the study of students, in particular, the inferior student group. Moreover, if we divide the student by more precise stoups, the ZPD will be more effective on teaching and learning in middle school. Lastly, we arrive at the conclusion that a continuous teaching with ZPD will improve the student attitude positively in solving mathematical problem even it does not appeared apparently on this test.
