Recent interest in software education has naturally led to interest in computer science. Computer science is the study of theory and principle of computer and computational systems. This knowledge and concept of computer science is fundamental to software education. Recently, "Computer Science (CS) Unplugged", which is an educational method for introducing students to concepts of computer science without using a computer, has been widely used in classes around the world. CS Unplugged is a method for learning the basic principles of computer science through diverse playing activities. The problem, however, is that these CS unplugged activities take place in class without an analysis of how closely they relate to the core subjects learned in real computer science. Therefore, in this study, we will study on the comparison between the core contents of computer science and the core contents of computer science contained in the various activities of CS Unplugged.

The Chinese Geography Standards for Senior Secondary Schools(trial) was released in 2003. The Standards put forward some changes for senior geography education, the changes in geographical education are reflected explicitly and implicitly by the textbooks. The purpose of this descriptive study was to review of the improvement of Chinese senior geography education by analyzing contents organization and coherence of the new standards-based geography experimental textbooks. The results of study are as follows. The textbooks adopts a student-centered approach through the way of 'more chapter topics with slimmed contents' and by introducing four type activities, geographical inquiries. These student activities are implicity encourages students' active acquisition of geographical knowledge what they have learned in their real lives. The organic coherence of the textbooks' contents rests on the compulsory and the elective subject relating to diversification of the learning areas. The organic coherence between the compulsory and the elective subject rests on diversification of the learning areas. More, looking at the arrangement of the four basic concepts(population, resource, environment, sustainable development) among the textbooks, it was imbalanced by subject.

The purpose of this study was to investigate the way applying a school garden for the creative experience activity on the school learning program. For this study, the 27s elementary students who were the 5th and 6th grades participated in this program. And the 10units lessons programs what were consisted with the inquiry, debating, and cooperating activities were developed, and applying to classroom and school garden. The key concepts of developing program were 'rocks which were in the school garden'. he results are follows, for the creative experience activity on the school teaching/learning program, the school garden has useful value as teaching/learning field. The teaching/learning activity applying the school garden makes an offer the awareness to students that the knowledges learned in school were actually relative with their life. Also, the students are affirmatively participate to learning, debate, and cooperate activities because the school garden is very familiar environment to them. Lastly, the students are interesting in learning classes because they think that the school garden environments will reform actually to new shape of their ideas. After this learning were finishing, most of students indicated their intention with satisfaction. Some of them suggested applying the additional program using the school garden. Consequently, the school garden has the very useful value for applying program of the teaching/learning in elementary school education.

As life quality have grown today, People have been greatly interested in health. Moreover, new knowledge and concepts are being applied in the medical facility field and that makes the field expand constantly. Hereby, this research is a study on design elements of dental clinics and the research goals are to understand interior design of current dental clinics by investigation and analysis on furniture, closing materials, colors and so on, and to investigate esthetic and functional environments for dental clinics through analyzing upcoming trends of inner spaces of dental clinics. The investigation was conducted by visits to four clinics per each research area, where are in Busan area and opened after year 2000 and are located in Seoul and Busan. Though the spaces of dental clinics vary according to the characteristics of each clinic, it generally has a consultation room, a waiting room and an X-ray room. The closing materials that make patients feel at ease are used in the waiting room, and ones that make patients feel tidy and fresh are used in consultation spaces, spare spaces, and management spaces. In Seoul area, antique and harmonic colors are used, and modernistic colors are used in Busan area. Reception desks, chair units, sofas and sink storage shelfs are the common furniture in the clinic. We have learned what are mentioned above by research and investigation on the component characteristics of dental clinic spaces. Based on these, more systematical and in-depth research should be continued.

The purpose of the study is to explore the experience of bullying in the workplace of nurses. The study period was April 1 2013 to July 5 2013. The subjects were 14 nurses who had experienced bullying at their workplace. Data were analyzed using Strauss and Corbin's grounded theory methodology. With data analysis, 139 concepts, 35 subcategories, and 13 categories were generated. "Disregard of presence by negatively learned inertia" was the central phenomenon for workplace bullying of nurses, and the core category was 'struggle to regain oneself'. This study will contribute to a change in individual and organizational awareness of bullying in the workplace by presenting a dynamic process of nurses experiencing bullying. Research is required on identifying workplace bullying status, monitoring methods and program development to reduce workplace bullying of nurses.

Multiplication is able to be described by using repeated addition, a Cartesian product, a scalar operation, rectangular array and area in many various context. Multiplication in various problem situations is learned by various of the teaching method and the order of teaching more than any other mathematical concepts and operations in elementary school. Nevertheless, the context of multiplication leaves further room for improvement. The purpose of this study is to examine the similarities and differences between the conceptual aspects of multiplication through the literature and to analyze the appropriateness of the teaching method and the order of teaching through textbook analysis. As a result of the study, it was found that multiplication of a scalar operation was introduced too early and did not properly reflect of meaning of multiplication as a scalar operation. There is also a need to use the concept of the rectangular array or area as a meaning of multiplication two quantities.

Since mathematical concepts are learned through the meaning of mathematical terms in school mathematics, learners must understand and use mathematical terms appropriately. However, the meaning of mathematical terms used in real life may be perceived differently from elementary mathematics textbooks, and this difference may cause confusion in learners' understanding of mathematical terms. Therefore, this study was intended to compare and analyze the mathematical terms in elementary mathematics textbooks used in Korea and a Korean dictionary. The findings revealed that the meaning of the textbooks was similar or different, and the subject indicated by each meaning was different. In this case, in order to prevent confusion among learners, it is necessary to supplement and guide each meaning by recognizing the difference between the mathematical terms in elementary mathematics textbooks used in Korea and a Korean dictionary.

To evaluate the educational programs at Science Education Center for the Gifted (SECG) on how it had influenced its graduates, we have surveyed the graduates with questionnaires categorized into four sections: scientific motivation, self-confidence, knowledge/inquiry activities, and peer-to-peer interactions. Of the graduates who studied at SECG for more than two years and are currently attending college, we questioned 26 students and interviewed 10 students. According to our research data, most students evaluated highly the quality of education they received at SECG; especially, in the areas of science knowledge/inquiry activities and social interactions with their peers. Based on the results from the interviews, for these gifted students with highly developed aptitude in science, we concluded that interactions with real-world scientists, investigative approach to and application of newly-learned scientific concepts, and emphasis on interactive activities with other gifted students at SECG were regarded as effective in promoting motivations towards science and self-confidence.

This study is the first step for us toward improving high school students' capability of statistical inferences, such as obtaining and interpreting the confidence interval on the population mean that is currently learned in high school. We suggest 5 underlying concepts of 'discretion of contingency and inevitability', 'discretion of induction and deduction', 'likelihood principle', 'variability of a statistic' and 'statistical model', those are necessary to appreciate statistical inferences as a reliable arguing tools in spite of its occasional erroneous conclusions. We assume those 5 concepts above are to be gradually developing in their school periods and Korean mathematics textbooks of grades 1-12 were analyzed. Followings were found. For the right choice of solving methodology of the given problem, no elementary textbook but a few high school textbooks describe its difference between the contingent circumstance and the inevitable one. Formal definitions of population and sample are not introduced until high school grades, so that the developments of critical thoughts on the reliability of inductive reasoning could not be observed. On the contrary of it, strong emphasis lies on the calculation stuff of the sample data without any inference on the population prospective based upon the sample. Instead of the representative properties of a random sample, more emphasis lies on how to get a random sample. As a result of it, the fact that 'the random variability of the value of a statistic which is calculated from the sample ought to be inherited from the randomness of the sample' could neither be noticed nor be explained as well. No comparative descriptions on the statistical inferences against the mathematical(deductive) reasoning were found. Few explanations on the likelihood principle and its probabilistic applications in accordance with students' cognitive developmental growth were found. It was hard to find the explanation of a random variability of statistics and on the existence of its sampling distribution. It is worthwhile to explain it because, nevertheless obtaining the sampling distribution of a particular statistic, like a sample mean, is a very difficult job, mere noticing its existence may cause a drastic change of understanding in a statistical inference.
