Researchers have suggested that students should be experienced in progress of geometric thinking set out in naive and intuitive level and deduced throughout gradual formalization rather than completed mathematics are conveyed to students for students' understanding. This study examined naive and intuitive thinking of students by investigating students' geometric problem solving without diagrams. The students showed these naive thinking: lack of recognition of relation between problem and conditions, use of intuitive judgement depending on diagrams, lacking in understanding of role of specific case, and use of unjustified assumption. This study suggests implication for instruction in geometry.

The purpose of this study was to compare Korean mothers' and fathers' reactions to their children's negative emotions. The survey with questionnaire was performed with 179 mothers and 179 fathers of children aged three to five-years-old from three child care centers in Seoul and Kyoungki Province. Parental emotion-related practices regarding children's negative emotions were assessed with an adaptation of the CCNES-R(Cortes, 2002), and parental reactions were categorized as problem-focused, emotion-focused, expressive encouragement, emotion-teaching, punitive, parental distress and minimizing. The main results were as follows. First, Korean mothers and fathers, in general, used more positive reactions than negative reactions when their children showed negative emotions, in particular problem-focused reactions were mostly used. In addition, Korean mothers were significantly higher than fathers on problem-focused and emotion-teaching reactions. Second, Korean mothers' and fathers' reactions to their children's negative emotions were significantly different depending on the educational level of mothers, mothers' job and fathers' job. But there was no significant differences in parent's reactions according to children's sex and age. The findings in this study provide implication for an association between parent's reactions to children's negative emotions and parent's socioeconomic background.

This study aims to understand the phenomenon related to private schools and present the implication for policy about private school, network text analysis about newspaper editorials in conservative and progressive media was conducted. The main results are as follows. First, in newspaper editorials, there were many issues about private university and there was a distinction between private elementary secondary school and private university. Second, in newspaper editorials, 'encouraging perspective' such as financial assistance and new private school like self-governing private high school and 'controlling perspective' such as withdrawal of problem private schools were both appeared. As a result, this study presents that the perspective for private schools needs to be re-established by 'accountability' as the educational institution and 'school capacity building' away from the past frame.

Scientific reasoning is one of the main concerns in current science education. This study have tried to answer on the question whether Korean science education has the potential to help improve of students' ability to think scientifically. Therefore, the present study investigated the relationship between reasoning patterns evident in science textbook and science examination items, and students' scientific reasoning skills across grades in Korea. 1975 subjects (1022 females and 953 males) were administered in the Lawson's Test of Scientific Reasoning skills. Forty seven science textbooks and 240 assessment instrument were analyzed by several scientific reasoning keys. Scientific reasoning patterns were adopted from Lawson's classification which characterized the patterns as the empirical-inductive and the hypothetical-deductive. This study found that reasoning patterns evident in textbook analyses and assessment instrumental items do not evidentce the potential to stimulate the development of students' reasoning skill. In order to improve the students' abilities to think and achieve, higher levels of reasoning must be included in the science textbook and examination. Further, some of scientific reasoning processes, such as generating hypotheses, designing experiments, and logical prediction, were not found in science textbooks and test items in Korean secondary schools. This study also discussed the educational implication of these results and further studies about to develop student's reasoning ability.

Recently, in rural areas have been occurred closed school due to reduce children of people who consider educational environment. In July 2009 statistic, Closed school are ut to 3,348; sale process(61%), lease(25%), neglect(14%). Closed school are not only local community education, but also to act as cultural and historical role. First of all, it will be utilized public facilities as well as welfare facilities for local residents. In this study suggests the welfare facility where is remodelled as good case so that it will use as a data when closed school need remodeling. The main contents is as follows; it is set the slope next to the school building, a classroom is remodelled 2 triple rooms which are installed Ondol and a toilet, teacher's room is converted into the canteen, corridors are converted into the kitchen. Having good condition in the area, close school is appropriate to use welfare facility and also effective to convert teacher's space into normal space, canteen, kitchen. Finally, developed 2~5 composition type of elderly facility.

The goal of this research is to development a coordination supporting script in CSCL and tried to measure of coordination supporting script's effectiveness. Therefor, in this research, after derive macro-script design principle and activity principle from former study and CSCL tool, after derive micro-script from role sign several reference, and then based on those principle developed coordination supporting script. As providing coordination supporting script or not, there will be the sense making difference of effectiveness of coordination supporting script in learning activity(shared mental model). The result of this study may have implication for the research on macro-script and micro-script and educational practice.

This study is to analyse the characteristics of Barrow's theorem on the historical standpoint of hermeneutics and to discuss the teaching-learning sequence for guiding students to reinvent the calculus according to historico-genetic principle. By the historical analysis on the Barrow's theorem, we show the geometric feature of the theorem, conjecture the Barrow's intention in dealing with it, and consider the epistemological obstacles undergone by Barrow. On a basis of this result, we suggest a purposeful and meaning-oriented teaching-learning way for students to realize the sameness of the 'integration' and 'anti-differentiation', and point out the shortcomings and supplement point in current School Mathematic Calculus.

The purpose of this paper is to analyze the elementary school mathematics textbooks according to the mathematics curriculum revised in 2007 which put emphasis on mathematics as a communication, and to find out the implication for improving the mathematics textbook of Korea. Mathematics textbooks are analyzed by five analysis criteria, which are suitability of communication activities, suitability of usage of terms and symbols, suitability of literary expressions, suitability of visual expressions and adequateness of mathematics and curriculum. As a result of analysis, it is found out that communication activities were generally reflected the intent of curriculum but there were incomplete terms usage and literary, visual expressions. So communication among authors, between authors and writers, authors and illustrators is necessary for improvement of mathematics textbooks.

There are two distinct processes, definite integral and indefinite integral, in the integral calculus. And the term 'integral' has two meanings. Most students regard indefinite integrals as definite integrals with indefinite interval. One possible reason is that calculus textbooks do not concern the meaning in the relationship between definite integral and indefinite integral. In this paper we investigated the historical development of concepts of definite integral and indefinite integral, and the relationship between the two. We have drawn pedagogical implication from the result of analysis.

The mathematics curriculum revision is currently underway based on the general curriculum revised in 2009. Two of the controversial issues in mathematics curriculum revision are 'grade band' and 'mathematical process'. To consider the introduction of those two aspects in mathematics curriculum, this study compares and analyzes international mathematics curricula focusing on grade band and mathematical process. As a result, grade band is judged to be not necessary, but mathematical process has a potential to provide practical implication for betterment of mathematics textbook and lesson.
