The classification is an important activity that is directly related to concept formation. Thus it will need to be made meaningful learning to classification through learner-centered teaching. But we doubts weather teaching and learning to the classification are reflected in the constructivist philosophy of 'learner-centered' well or not. The purpose of this study was to analyze critically the content of elementary textbooks and guidebook for teachers relating to the classification of angles and triangles in terms of constructivism. As a result, there is a problem in the classification of angles that are not provided a reasonable chance to set criteria by agreement of the communities. There is a problem in the classification of triangles that has the characteristics of radical development in terms of diversity. In addition, response of students was predicted like anyone who already acquired knowledge. And it has the shortcomings that the opportunity to have a choice and a discussion to hierarchical and partition classification are not provided. The followings are proposed based on such features; faithful reflection of 'Learner-centered' principle, careful prediction of student response, teaching that focus on process than results.

This study was performed to investigate the dietary habit based on residence types of male college students who registered nutrition course for nonmajor. Self reports on dietary habit and one-day dietary records were obtained from 158 male college students in Chungbuk area. The distribution of residence type of male college student was as follows; self-boarding(43.0%), home(41.1%), boarding with meal(12.7%), and others(3.2%). The mean age of subjects were $22.6{\pm}2.5$, and the mean height and weight were $175.0{\pm}5.6cm\;and\;69.1{\pm}9.3kg$, respectively. The dietary habit of male college students considered to be taken more care of, showing indifference to dietary balance, irregularity of meal, and skipping breakfast. One-day dietary records by 24hr recall methods also showed less diverse food intake(mean DVS, 12.7; mean DDS, 3.92). Especially, the students with self boarding residence were more likely not to eat properly, including indifference to dietary balance, irregularity of meal, skipping breakfast, frequent dining-out, high experience of smoking and drinking, and low DVS and DDS. Also the students with self boarding residence seemed not to make a good choice for food, showing high food intake frequency score in canned food, fast food and instant ramyun, while low score in fruit and fishes. More attention should be taken for self-boarding students to recognize the problems in their own dietary behavior, and more practical suggestion to improve their dietary status would be necessary.

Mathematics is extreme the differences of the scholarly attainments in comparison with other subjects at a middle school. Specially, the students at islands and places leave much to be desired the scholarly attainments standards of mathematics. Therefore, every school takes movement class according to level these days. And the small schools put in effect the cooperation of group work through the small groups. These classes are effective at the scholarly attainments extension to some degree, but each student is extreme the differences of scholarly attainments. On this, the small school was the subject of study at the present research and put in effect the cooperation of group work through the small groups. The students were divided in three groups; the top class, average, the low class, And they were offered the fitting textbooks matching the cooperation of group work and the opportunities of discovery learning fitting an individual ability and standard. Consequently, some educational materials were made, for example, question papers, commonness learning materials, choice learning materials. These materials were put in effect to the students to be able to succeed discovery learning. With this, the students were investigated an interest of mathematics and the influence giving at the studies attainment. And the students were put in effect the cooperation of group work through the small groups to improve uniformity and sturdiness of the mathematical education. The conclusion at the present research is as follows. 1) When the students put in effect the cooperation of group work through the small groups, the scholarly attainments of mathematics totally didn't display useful changes as improvement. However, the students of average and the low class gradually seemed to improve the scholarly attainments of mathematics as the help of the top class positively. 2) An individual and cooperation learning in the method of the cooperation of group work through the small groups displayed many changes at the learning attitude of the students by means of discovery learning thanks to the learning heads. 3) When the investigator put in effect the cooperation of group work through rather the small groups than the large groups, the numbers of the students experiencing interest about mathematics increased in 26% and this learning method should continue to progress.

The purpose of this study was to examine the needs of learners in an advanced major course in a bid to strike a balance between theory and practice. And it's also meant to suggest an actual case of that effort in an advanced course. As a result of analyzing the collected data, the largest number of the learners who signed up for the advanced course chose that course to earn a bachelor's degree, and the second greatest group did that to bolster their expertise. The name of the college that offered that course (41.4%) had the most impact on their choice of it, followed by accessibility(28.6%). The most common thing they practiced in the oral health education course as one of major courses was forming a lesson plan, followed by teaching at schools and kindergartens, trial student teaching, producing PPT, making OHP materials, making a bulletin board and producing leaflets. During clinical activities for oral health education, the largest group considered it necessary to learn about more theories on educational psychology(54%), followed by the production of teaching media(29.9%) and teaching methods(25.3%). Likewise, the greatest group found it more necessary to practice educational psychology(42.5%), followed by the utilization of media(37.9%) and teaching methods(28.7%). An one-on-one interview was implemented before and after their classes to obtain more detailed information on their needs, and what their needs were in relation to the given curriculum was eventually confirmed, which made it possible to offer better education in response to their needs.

The present study investigates the seventh and the eighth graders' perception of Free Learning Semester Programs offered by libraries by developing a survey questionnaire on students' needs for Free Learning Semester Programs of Libraries. The skills that middle school students want to improve in Free Learning Semesters are career exploration skills, and the type of Free Learning Semester that is most intensively implemented is career exploration activities. Programs are often offered in the form of experiential classes. Regarding the activities that the students want to participate during Free Learning Semester, the most preferred activities included field experience activity in the career exploration domain, cooking class in the student choice program, smartphone app development in club activities, design activity in the art domain, the badminton in the physical education domain, and using iPad in the information use skills. In addition, among the library programs in coordination with Free Learning Semester, the students liked the occupational experience program most. Future studies need to include the development and implementation of Free Learning Semester Programs based on students' opinions, and investigate their satisfaction with the Free Learning Semester Programs offered by libraries.

This study attempted to analyze and confirm the correlation between self-concept and the degree of satisfaction on clinical practice. The subjects of the survey were 194 junior and senior students selected from S universities by questionaire from Nov. 1 to Nov. 30, 1983 in Seoul. The collected data was analyzed by t-test, AN-OVA, Pearson correlation according to purpose of study. The results were as follows: 1. Self-concept by religion was significant (F = 4.51, df=4/185, p= .002). 2. In the motives of selecting the nursing, most of students chose the nursing depending on their altruism(62.9%), ability and aptitude(57.7%) and better opportunity of studying abroad and Setting a job(49.5％） respectively. 3. The degree of clinical practice satisfaction was low as 2.80 of a total score 4.0. The degree of satisfaction of contents(3.33) revealed to be high. Compared with the degree of satisfaction on instruction(2.77), practice hours(2.83), practice environment (3.65), and clinical evaluation(2.60) revealed to be low. Religion and choice order of the admission were not significant in satisfaction of clinical practice(t=.37, p=.715). The main hypothesis that“The more positive self concept will be, the higher the degree of satisfaction on clinical practice will be”was not supported (r= .0509, p=.240). The first sub-hypothesis that“The more positive the cognitive self-concept will be, the higher the degree of satisfaction will be”was partially supported. Because favorite-isolated self-concept was significantly correlated with the satisfaction (r=.1189, P=.005). The second sub·hypothesis that“The more positive the evaluational self-concept will be, the higher the degree of satisfaction on clinical practice will be”was not supported. As a above results, self-concept was not influenced to the degree of satisfaction on clinical practice, therefore it is required that environment, instruction method and evaluation for clinical practice should be refined and improved by clinical administrators and nursing faculties for nor-sing student's satisfaction on clinical practice.

Purpose: This study aims to analyze the effectiveness of Tai chi exercise for improving balance and its tendency and helps to identify directions for future research. Method: 19 articles from Medline search of foreign journals(1981-2003) and 5 from Korean nursing journals (1981-2003) were surveyed. The contents analyses were focused on outcome measures and relative factors regarding balance. Result: Variable measures for balance were used in Tai Chi studies relating to balance. They included the functional measures such as 14 single-leg stance, 7 walking in physiological measures and 7 laboratory-based balance measures were done with platform stability test. The measure of effective Tai Chi exercise depended on the health status of subjects and the methods. Health status of subjects were only on physically inactive older adults in 17 articles and arthritis patients in 7 articles in the Tai Chi study. The significant effects of Tai Chi exercise on balance was revealed after 10weeks duration. Conclusion: Considering the results, Tai Chi exercise is more effective than any other studies for walking balance. But the reports on the outcome are inconsistent with wide variations in the choice of balance measures. It is suggested that future studies analyze systemic change through meta analysis and have a wide variety of subjects who need postural control and balance control. The methods of measures should be distinct from the balance state of subjects for the effectiveness of Tai chi exercise.

In 2005, descriptive assessment was introduced to increase students’ higher mental ability like problem-solving ability and creativity. Every year the ratio of descriptive assessment increases and it is regarded as an alternative evaluation to a multiple-choice item which measures simplicity knowledge. Externally the descriptive assessment took a root in school, but we can’t say definitely that it meets its original goal. In this paper, science descriptive assessment items of 5 middle schools in Gyeonggi-do were analysed; examiners was interviewed about how well they understood the characteristic of the assessment items. According to the analysis, characteristic of the items are ① unequal distribution of unit, ② difference of item’s type by unit, and ③ disappearance of measuring higher mental ability. It is considered that there are several factors of these characteristic - the lack of teachers’ ability to make assessment item; understanding of assessment instrument. These factors can be explained by the lack of assessment expertise. So the society’s effort is needed to raise teacher’s ability for the descriptive assessment.

Purpose: The aim of the study was to investigate nursing students' awareness of nursing and future career according to school years and gender. Method: Data was collected using a self-report questionnaire from October to December, 2007. Participants were 279 second year and 250 fourth year nursing students from 6 universities located in Seoul, Gyeonggi-do, Chungcheong-do, Gangwon-do, Jeonla-do, and Gyeongsang-do. Result: 1) The senior showed higher scores in 'a job with plenty of spare time', and 'good possibilities to be promoted' than the sophomore. Otherwise the senior students showed lower score in 'possibilities for part-time working' than the sophomore. 2) The senior showed higher scores in 'cooperative relationship', 'physical health', and 'contribution to nursing' than the sophomore. But in 'nursing skill', the senior showed lower score than the sophomore. 3) There were significant differences in wanting department, wanting graduate school, and major obstacles for the longer working between the sophomore and senior. 4) Male students were lower academic performance than female. 5) There were significant differences 'a job with social reputation', and 'contribution to nursing' by gender. Conclusion: These results suggest it's important that nursing educators make nursing students improve their job professionalism and guide nursing students' future career in view of students' gender and school year.

When they chose their major, the most influential was their parents and relatives, the largest number of 435(43.5%) replied, About the motivation for selection their jajor, 454(45.4%) answered the most it seemed to be a bright future specialty. On that question, more freshmen(51.0%) answered theyu expected good trend than sophomores and juniors and more women students(48.8%) did so than men ones.(P<.05) 2. While 619(61.8%) were familiar with major before applying, only 68(6.85%) knew their major very well at that time. More freshmen(62.5%) applied in the state of well-knowing what their major is than sophomores and juniors did.(P<.01) More women students(40.9%) applied not knowing it than the counterpart. About the time for choice, 795(79.5%) answered the most one of application days. More women students(81.0%) chose their major during the application time(P<.01) 3. The satisfaction survey shows 438(43.8%) are satisfied and 165(16.5%) are not. More men students(47.2%) are satisfied.(P<.01) The factor their satisfaction is their major come together with aptitude(44.7%), 196ppl), and the dissatisfaction factor is the difficulty of the theory and practice.(30.8%, 171ppl) 4. If they could change their major, 454(46.6%) wouldn't do so, while 541(54.4%) would shift their major to other fields. More freshmen(49.5%) wouldn't change than sophomores and juniors. Neither did more men students(4938%) than women. Within the same grade, there's no meaninful difference.(P<.01) 5. On the satisfaction in the lectures of the professors of their major, 464(46.5%) said the lecutres are excellent, 102(10.2%), they are not.
