The contents of high school 'Common science' textbooks was analyzed qualitatively and quantitatively. Seven common science textbooks were selected and its contents, structure, inquiry, activities, appendix and its characteristics were investigated, and analyzed using the Goal Clusters of Project Synthesis and Romey's indices of text evaluation were calculated. The contents of each unit are not much different among textbooks because they are written according to the curriculum ordinance and textbook guidelines of the Ministry of Education. The textbooks was consist of $471{\sim}519$ pages. It was distribute similarly among the chapter of 'materials', 'forces', lives' and 'earth'. The chapter of 'energy' and 'environment' was treat significantly. The contents and structure of common science is a mere physical consolidation. I make an alternative plan that a topic form. Inquiry activities used in the textbooks are 11 type, however most of that is interpretation of data, experiment, survey and discussion. Ninety six percents of the experiment, belong to the 1st level, four percents of that belong to the 2nd level of the Schwab's inquiry level and there are no activities of the 3rd level. Little attention is given to Goal Cluster I, II, IV in the common science textbooks currently employed. Its content should be broadened to include all Goal Clusters of Project Synthesis. Homey's indices representing the degrees of student involvement. are $0.57{\sim}1.14$ for sentence analysis, $0.60{\sim}1.67$ for figure and diagram analysis, $0.67{\sim}1.50$ for analysis of questions at chapter ends, respectively, student activity per page investigated being $0.6{\sim}0.9$. But chapter summaries cease to repeats the conclusions of the chapter also it be rather formally and inattentively written.

The present study proposes and examines a new type of multiple-choice math test. In this format, the options are the intermediate derivatives of the math problem solution process rather than the final answers. This idea originates from the studies on the effect of worked-out examples. In these studies, it has been shown that students learn better when they were presented with worked-out examples than when presented with final answers by themselves. In line with these findings, we introduced the intermediate derivatives of the solution process as the options of multiple-choice items so that the test-taker will have a chance to examine the solution process. The test was implemented as a computerized test in which students can solve problems in a short answer format, and then pick a multiple-choice option which appears when requested. The experimental group had multiple-choice options which were intermediate derivatives of the solution process, and the control group had the final answers as the options as in most multiple-choice tests. The participants were 6th graders in elementary school. The posttest results revealed that the average score of the experimental group was higher than that of the control group. The results suggest that tests that use intermediate derivatives of the problem solution process as options can be used as learning tools in the classrooms. Finally, directions for further studies were discussed.

Contemporary belief is that the creative talented can create new knowledge and lead national development, so lots of countries in the world have interest in Gifted Education. As we well know, U.S.A., England, Russia, Germany, Australia, Israel, and Singapore enforce related laws in Gifted Education to offer Gifted Classes, and our government has also created an Improvement Act in January, 2000 and Enforcement Ordinance for Gifted Improvement Act was also announced in April, 2002. Through this initiation Gifted Education can be possible. Enforcement Ordinance was revised in October, 2008. The main purpose of this revision was to expand the opportunity of Gifted Education to students with special education needs. One of these programs is, the opportunity of Gifted Education to be offered to lots of the Gifted by establishing Special Classes at each school. Also, it is important that the quality of Gifted Education should be combined with the expansion of opportunity for the Gifted. Social opinion is that it will be reckless only to expand the opportunity for the Gifted Education, therefore, assessment on the Teaching and Learning Program for the Gifted is indispensible. In this study, 3 middle schools were selected for the Teaching and Learning Programs in mathematics. Each 1st Grade was reviewed and analyzed through comparative tables between Regular and Gifted Education Programs. Also reviewed was the content of what should be taught, and programs were evaluated on assessment standards which were revised and modified from the present teaching and learning programs in mathematics. Below, research issues were set up to assess the formation of content areas and appropriateness for Teaching and Learning Programs for the Gifted in mathematics. A. Is the formation of special class content areas complying with the 7th national curriculum? 1. Which content areas of regular curriculum is applied in this program? 2. Among Enrichment and Selection in Curriculum for the Gifted, which one is applied in this programs? 3. Are the content areas organized and performed properly? B. Are the Programs for the Gifted appropriate? 1. Are the Educational goals of the Programs aligned with that of Gifted Education in mathematics? 2. Does the content of each program reflect characteristics of mathematical Gifted students and express their mathematical talents? 3. Are Teaching and Learning models and methods diverse enough to express their talents? 4. Can the assessment on each program reflect the Learning goals and content, and enhance Gifted students' thinking ability? The conclusions are as follows: First, the best contents to be taught to the mathematical Gifted were found to be the Numeration, Arithmetic, Geometry, Measurement, Probability, Statistics, Letter and Expression. Also, Enrichment area and Selection area within the curriculum for the Gifted were offered in many ways so that their Giftedness could be fully enhanced. Second, the educational goals of Teaching and Learning Programs for the mathematical Gifted students were in accordance with the directions of mathematical education and philosophy. Also, it reflected that their research ability was successful in reaching the educational goals of improving creativity, thinking ability, problem-solving ability, all of which are required in the set curriculum. In order to accomplish the goals, visualization, symbolization, phasing and exploring strategies were used effectively. Many different of lecturing types, cooperative learning, discovery learning were applied to accomplish the Teaching and Learning model goals. For Teaching and Learning activities, various strategies and models were used to express the students' talents. These activities included experiments, exploration, application, estimation, guess, discussion (conjecture and refutation) reconsideration and so on. There were no mention to the students about evaluation and paper exams. While the program activities were being performed, educational goals and assessment methods were reflected, that is, products, performance assessment, and portfolio were mainly used rather than just paper assessment.

The purpose of this study is to identify the teaching professionalism of the two teachers for secondary science-gifted students in perspective of teaching orientations. Both teachers have been taught biology to secondary science-gifted students for more than six years and they have received in-service training in gifted education. Teachers' orientations were investigated through in-depth interviews and observing lessons. For the data collection, videotapes were recorded during two lessons and two in-depth interviews for each participant were conducted. All recorded data were carefully transcribed and analyzed. Some unique characteristics of teaching were identified from the class instruction of each participant. Both teachers revealed 'Open Inquiry' orientation. This was reflected by their educational goals and beliefs that they should help science-gifted students to grow themselves as scientists by enhancing their inquisitiveness and creative problem solving ability. However, each teacher had shown different teaching orientations such as 'Academic Rigor' and 'Discovery' that seemed to have influence on the level or the range of subject matter covered in the classes. Teachers' science teaching orientations have been changed by their subject of teaching and their experiences in teaching the gifted. In the process, teachers' educational philosophy about gifted education plays an important role in teaching orientation. Based on the ongoing teachers' efforts for enhancing his/her professionalism, the teachers seemed to critically review theoretical knowledge of the science teachers in gifted education through self-reflection on their own teaching methods. When teacher's educational philosophy about gifted education was established and internalized, science teaching orientations in teaching practice seemed to be consistent with his/her goal of teaching.

The purpose of this research is to investigate the actual conditions of primary school science teaching and ways to improve it. In elementary science teaching, teachers themselves tend to have science misconceptions and insufficient science content knowledge. Experienced teachers argued that it could be hard for elementary teachers with lack of science content knowledge to provide their students with meaningful learning experiences of science. Based on the general characteristics of elementary teaching and the awareness of elementary teachers' insufficient science content knowledge, we explored the real situation of the elementary science classroom. We conducted open-ended interviews with teachers and focus group discussions on a regular basis to analyze and compare classes of five primary school teachers. Data analysis focused on why elementary students avoid science classes in upper grades of elementary school and why elementary science classes always need hands-on activities. We also discussed ways to turn hands-on investigation into minds-on investigation by connecting it to important ideas in science. Based on the results, we suggested ways to improve inservice teacher training such as designing supplementary in-service training focused on content knowledge for primary school teachers, setting up professional exchange or collaboration between primary and secondary teachers, and introducing subject-specialized teachers for the fifth and sixth graders of primary school. In particular, considering elementary teachers' insufficient science content knowledge, employing science subject matter specialists in the elementary school could be a useful strategy.

The previous study has assumed that dialogue and debate could not have been activated by the hierachical Confucian norm and political authoritarianism in Korean society. Political democracy has developed in Korean society since 1987. But many observers have pointed out that the culture of debate still remained undeveloped in Korean society. This study assumes that the key factor of determining the quantity and frequency of debate is the polilitical factor such as authoritarianism, but the determining one of qualitative dimension such as debate competence derived from the epistemological tradition. In order to ascertian this hypothesis, this study explored the epistemological basis of Confucian thoughts in comparison with the classical Greek thoughts. In classical Greek society, philosophers considered that the purpose of debate is to find and to ascertain the truth. Bur Confucian scholors didn't look upon questioning the truth. Instead they considered practicing or doing of the truth worthful. Therefore, in a society which were much influenced by the Confucian thought, the culture of debate could not have been developed.

Social enterprises have been concerned with the social problems and their market survival, simultaneously. They show diverse types of organizational identities in order to pursue such hybrid goals. This study examines how the social enterprises shape their identities. In particular, it focuses on regional and industry environments that influence the types of the organizational identities of the social enterprises. This study categorizes 219 social enterprises, founded in the environmental sector, into social oriented single identity, business oriented single identity, and mixed identity enterprises using the 2014 and 2015 Social Enterprise Directory published by Korea Social Enterprise Promotion Agency. Findings are as follows: First, there are more social enterprises with a single identity in the metropolitan environment, compared to ones in the non-metropolitan environment, and social enterprises with a mixed identity are more likely to be established in the non-metropolitan environment than ones in the metropolitan environment. Second, there are more social enterprises with a social oriented single identity in the emerging industry environment than ones in the mature industry environment. Also, more social enterprises with a business oriented single identity are formed in the mature industry environment than ones in the emerging industry environment.

The aims of this study is figure out the characteristics of justification patterns and mathematical representation which are derived from 14 mathematically gifted middle school students in the process of solving the spatial tasks on Archimedean solid. This study shows that mathematically gifted students apply different types of justification such as empirical, or deductive justification and partial or whole justification. It would be necessary to pay attention to the value of informal justification, by comparing the response of student who understood the entire transformation process and provided a reasonable explanation considering all component factors although presenting informal justification and that of student who showed formalization process based on partial analysis. Visual representation plays an valuable role in finding out the Idea of solving the problem and grasping the entire structure of the problem. We found that gifted students tried to create elaborated symbols by consolidating mathematical concepts into symbolic re-presentations and modifying them while gradually developing symbolic representations. This study on justification patterns and mathematical representation of mathematically gifted students dealing with spatial geometry tasks provided an opportunity for understanding their the characteristics of spacial geometrical thinking and expending their thinking.

In recent years, parents of students and government have been taking a growing interest in education for the gifted students and there are many research reports about the gifted education. Most of the reports, however, focuses on the conceptional feature of the gifted education program such as organization, operation, management, evaluation, etc,. In other words, there are very few researches on instructional materials for gifted students even though the materials is a critical factor for successful education programs. So, this paper introduces a lecture notes used in a personal education for gifted students to contribute in developing education contents in computer science area. The instructional materials titled as "The Necessity and Application of Matrix in Computer Science" is based on linear equation to usher the students into creative problem recognition and groping for solutions. Also, the instructional materials is useful for students to understand the tight mathematics-computer science relationship and the basic concept of liner algebra.

J. Bernoulli first discovered the method which one can produce those formulae for the sum $S_n(k)=\sum_{{\iota}=1}^n\;{\iota}^k$ for any natural numbers k. After then, there has been increasing interest in Bernoulli and Euler numbers associated with Riemann zeta functions. Recently, Kim have been studied extended q-Bernoulli numbers and q-Euler numbers associated with p-adic q-integral on $\mathbb{Z}_p$, and sums of powers of consecutive q-integers, etc. In this paper, we investigate for the historical background and evolution process of the sums of powers of consecutive q-integers and discuss for Euler zeta functions subjects which are studying related to these areas in the recent.
