Mental arithmetic has recently gained a higher profile in primary school mathematics. The study aims to reflect didactical background of mental arithmetic in number and operations curriculum for primary school mathematics. In order to attain these purposes, the present paper describes the meaning of mathematical literacy and didactical background of mental arithmetic on which have been laid emphasis in relation to mathematical literacy in many countries. Also it shows current suggestions for mental arithmetic instruction in Everyday Mathematics Project in USA, Numeracy Number Project in Great Britain, TAL project based on Realistic Mathematics Education in the Netherlands, and mathe 2000 project in German in order to gain practical ideas for teaching mental arithmetic. Furthermore, it discusses mental strategies of students and didactical models for improving mental arithmetic instruction based on the results of many researches. Under these theoretical foundations, it is analyzed how mental arithmetic is developed in our number and operations curriculum, focused on mental strategies and didactical models. Finally, implications for improving our mental arithmetic instruction are discussed.

The aim of this study is to look into the didactical background for teaching proportional reasoning in elementary school mathematics and offer suggestions to improve teaching proportional reasoning in the future. In order to attain these purposes, this study extracted and examined key ideas with respect to the didactical background on teaching proportional reasoning through a theoretical consideration regarding various studies on proportional reasoning. Based on such examination, this study compared and analyzed textbooks used in the United States, the United Kingdom, and South Korea. In the light of such theoretical consideration and analytical results, this study provided suggestions for improving teaching proportional reasoning in elementary schools in Korea as follows: giving much weight on proportional reasoning, emphasizing multiplicative comparison and discerning between additive comparison and multiplicative comparison, underlining the ratio concept as an equivalent relation, balancing between comparisons tasks and missing value tasks inclusive of quantitative and qualitative, algebraic and geometrical aspects, emphasizing informal strategies of students before teaching cross-product method, and utilizing informal and pre-formal models actively.

The purpose of the present study was to examine the emotional characteristics related to gifted children's happiness, such as happiness index, optimism, psychological wellbeing, and school education happiness. For the study, 201 gifted students who were currently enrolled in gifted education centers, 124 potentially gifted students who were nominated by teachers for their scientific interests and high performances, and 141 general middle school students participated in the study. The results indicated that both the gifted and the potentially gifted students showed significantly higher emotional characteristics related to happiness compared to the general students. There was no significant difference between the gifted and the potentially gifted in the diverse aspects of happiness. Interestingly, significant interaction between gender and giftedness was found. Girls were happier when they were identified as the gifted, compared to the boys. Variables related to the happiness were also investigated, and the results indicated that the peer relationship and the family happiness were the most important variables that explained gifted children's happiness in general.

This study aims to analyze school management consultants' competency from the perspective of professional and prospective consultants and to draw implications for their competency building and work. To achieve the purpose of this study, an importance survey and a retention survey of school management consultants' competency were performed. The main results are as follows: school management consultants' key competencies are concept, background and principle of school management consulting, process and method of school management consulting, contents of school management, listening and empathy, communication, problem solving, teamwork and collaboration, interpersonal skills, authenticity, commitment. Professional and prospective consultants' perception of school management consultants' competency were different, and importance and retention of prospective consultants' competency changed through the consulting experience. It is significant that the result of this study can be reflected in school management consultants' training and qualification and conform the 'learning' principle of school management consulting.

This study is to find out experiments of Earth's revolution and which experiment is effective by school level. Researcher investigated and developed eight experiments for students to learn Earth's revolution. Twenty six pre-service teachers did these experiments, discuss about them, chose an effective experiment of Earth's revolution and wrote the reason why. As a result, they thought that an experiment of seasonal constellations is effective for elementary school students, an experiment of seasonal star's spectrum is effective for secondary school students and an experiment of the superior planets' retrograde motion is effective for university students. Pre-service teachers gave reasons such as hands-on experience, connection with textbooks, background knowledge and higher-level thinking.

The purpose of this study was to explore the status of 'Gesamtschule' (eng. Comprehensive school) in Germany and to suggest future direction for Korean education. To achieve this purpose, this study explored 1)the background of adopting Gesamtschule and its developing process; 2)Change of school structure since 2000 and the status of Gesmatschule. Results of this study indicated that 1)Changing school structure in Germany focused on closing educational gap caused by social class differentials; 2)Gesamtschule and other school model, similar with Gesamtschule are spreading widely in relation to change of school structure in secondary education; 3)Expanding this school model contributed to closing educational gap by analysing of recent results of PISA. This study suggested that efforts for closing educational gab in korean school should not only concentrate on supporting students, but also accompany discussion about change of school structure.

The purpose of this research is to identify internal and external factors that affect specialized technical high school students' career decision status. It then uses career decision types to predict the variables which have the impact on emotional aspects of specialized technical high school student who feel comfortable or uncomfortable after career decision in order to help specialized technical high school students choose their career. The subject of this study consist a total of 809 male and female students attending specialized technical high school located in South Korea. Data were analyzed to investigate the types of career decision status of specialized technical high school students using the SPSS 21.0 program. The results obtained through the study were as follows. Types of career decision status of specialized technical high school students were divided into four groups based on career decision status and types of emotional state. Results showed the decision-comfort(51.3%), decision-discomfort(25.6%), indecision- discomfort(15.3%), indecision-comfort(1.3%) in order. Social support were selected as variables affecting the comfort and discomfort of two groups and the determining factor which distinguished four groups. Result of the analysis showed that social support has statistically significant impact on whether it was decision or not and comfort or not. But career decision-making self-efficacy has no big impact on career decision types. Taking all results of this study together, we can see that specialized technical high school students feel comfortable and they decide the career, but still many students feel uncomfortable on their decision after deciding their career. It suggests the need of development and operation of program about emotional status of career decision which can help specialized technical high school students prepare their career comfortably after they decide on the career, and the need of segmented career counseling approach including social support group.
