The objective of this study is to analyze the effects 6th grade mathematics lessons applying story making have on the mathematics achievement and attitude toward mathematics. For this study, using two examination devices for measuring mathematical attitudes and mathematics learning achievement, a pre-test and post-test were conducted. In the pre-test, it was found that the two groups are identical groups. The post-test was used for verifying the research problems and the results of post-test were analyzed using t-test. The findings of this study are below. First, lessons applying story making influenced the mathematics achievement of children. This implies that lessons applying story making are more effective for improving a mathematics achievement than a general teaching and learning method. Also, when carrying out the t-test of pre-test and post-test results of learning achievement in experimental groups, there was a significant change as well. It is therefore supposed that lessons applying story making have positive effect on the mathematics achievement of children. Second, lessons applying story making influenced the mathematical attitudes of children. This implies that the lessons are more effective for improving mathematical attitude than a general teaching and learning method. Also, when carrying out the t-test of pre-test and post-test results of mathematical attitudes in experimental groups, there was a significant change as well. It is therefore supposed that lessons applying story making have positive effect on mathematical attitudes of children. From the results, it was found that mathematics lessons applying story making can be used to change the mathematics achievement and mathematical attitudes of students positively.

The purpose of the study is to visualize the concept of water circulation in elementary school students through science behavioral system. Elementary school students found it difficult to understand concepts related to the water cycle. Most of the elementary school children think it rains because the clouds are heavier. It is most difficult to explain invisible concepts to elementary school children. Also, experiments in current textbooks are likely to disrupt scientific concepts. Accordingly, conventional water cycle, dew, fog, and cloud experiments were integrated into one system. The researchers then developed a device that allowed students to see the water's circulation at a glance. It is intended to enable integrated thinking on evaporation, condensation and precipitation. In addition, a instruction program to guide students using the system has been developed to demonstrate its effectiveness. Employing a quasi-experimental design, the participants were measured on their concepts of evaporation, condensation, and water circulation before and after participation. The findings indicated that the experiment is more effective in changing the concepts of evaporation, condensation, and water circulation than in previous experiments. Also, the optimal conditions for making use of the device were found, and there were no various experimental parameters, such as condensation.

Notwithstanding various discourses among scholars on the unique characteristics of comics, in Korea there is nevertheless a scarcity of quality research on the subject. Therefore, to promote quality research, it is important to consider how to best use source materials in the field of comics scholarship. Source materials can generally be categorized into three types: pre-existing comics, scholar-generated comics and user-generated comics. For this study, user-generated comics are the primary source materials, specifically comics created by mothers of children with disabilities. It is intended that this research will contribute to the future direction of education for mothers who suffer from a relative sense of alienation as the primary caregivers of children with special needs. Although therapeutic arts and cultural programs make a tremendous difference in the lives of these mothers, teaching methodology and educational opportunities are extremely limited. Furthermore, existing scholarship focuses primarily on either the psychological transformation of the individual or a phenomenological approach for parents to understand and deal with the problematic behavior of children with disabilities. However, this research does little to help improve learning programs for these parents. Against this backdrop, this research sets out to consider the potentiality and effectiveness of using comics in the education of mothers of children with disabilities. These mothers, by creating comics, develop better awareness of themselves in a positive and enriching way. It is therefore hoped that this research provides a useful analysis for developing the potentiality and effectiveness of these programs.

The purpose of this study was to find out the feature of children's play according to a player number restriction rule in the free choice activities. And it is expected that the result of this study will contribute to improving the management of free choice activities. The participants of this study were a homeroom teacher, professor as a co-researcher and 25 4-year-old children of a private kindergarten. The data were collected by observation, children interview and reflective journal of the teacher from July to October in 2014. The results indicated that the children were stressed out with using name cards for presenting center selection, showed overcompetitive behaviors, and frequently violated the rules. The researchers found that the restriction rule had some dysfunctions, which were interferences of moral development, social-emotional development, self-regulation development, preventing safety-accident and free choice behavior. The researcher as a teacher abandoned the player number restriction rule, and observed the children's play. As a result, children's self-regulation abilities on physical space, play and conflicts improved and the teacher changed her strategy when managing free choice activities. Based on the results, the needs of various restriction rules and appropriate methods for applying the rules in free choice activities were further discussed.

Textbooks corresponding to curriculum goals are necessary because they are specific products of curriculum and are the most important materials for teaching, learning, and evaluation. In particular, learning objectives written in textbooks should be clearly described because they play a role in promoting learning by showing learning goals to learners clearly. This study analyzed the characteristics of verbs used as predicate of learning objectives written in high school physics I and II textbooks of Korea and compared them with physics textbooks of Singapore and the United States. Results show that Korean textbooks have less kinds of verbs compared to those of Singapore and the United States, and the verbs with abstract and comprehensive meaning such as 'understand' and 'know' were mainly used. In American textbooks, it was noticeable that no verbs have been used by more than 10%. When classifying the learning objectives in the two Korean textbooks, cognitive domain accounted for 98 to 99%, and inquiry domain accounted for only 1% to 2%. With regard to physics textbooks of the United States, inquiry domain accounted for a large proportion of domains in learning objectives compared with physics textbooks of Korea and Singapore. Physics textbooks of Singapore were similar to those of Korea in that learning objectives were biased toward cognitive domain, but differed from those of Korea in that learning objectives were specifically described using action verbs.

Recently in order to ensure future competitiveness in schooling a paradigm shift which focuses on key competency is demanded. In these circumstances, there are lots of researches on competency in other subjects. However, in informatics the number of researches relate to competency is lacking. Thus, the purpose of this study is to develop competency model for teacher of informatics in high school. For achieving this purpose, we develop research methods and procedures, and conduct several researches such as Focus Group Interview and surveys. Overall research process of this study is as follows: First, we develop competencies of informatics teachers, which consist of 6 categories, 17 competencies, and 66 behavioral indexes as a draft. Second, we verify the content validity of the competencies through FGI, and revise the competencies into 5 categories, 11 competency-units, and 159 behavioral indexes. Third, we conduct a survey for verification of the revised content validity again to informatics teachers, professors and researches. As a result, the major findings of the survey reveal that the Conbarch's ${\alpha}$ of each competency-units is over .9, and that the appropriateness of all items is over 3.5. According to this result, we confirm our competency model for teacher of informatics in secondary education.

Publication Industry of scientific technology is showing tendency of decreasing in sales, which clearly draws down curve since 2000. The printing culture is declining whether it is because of trend avoiding pure science or technological science and engineering, advancement of mass media or increasing frequency of using internet. Nevertheless, researcher considered car industry in publication industry as a life-long purpose for study. For this reason, the researcher tried to find the variables of the marketing which give impact on the customers such as student group and consumer who buys cars, when buying professional books. The found variables are expected to have a huge impact on the publication industry of professional books. As a result of research, in the area of the vision and motive, most said that they have "chosen a major in car because they liked car in usual base." In the stage of recognizing the problem, they buy the books when it is inevitably necessary. In the stage of searching for the information, they get information from advertisements, friends, professors, internet or sales clerk in book stores. In the stage of evaluation, they look for the title and the publication date of the books. In addition, in the stage of deciding purchase, "buy immediately" was the most frequent answer while impulsive purchase is the least frequent answer. In the stage of evaluating after purchase, many of them mostly are satisfied with their purchase.

Productive struggle is a student's persevering effort to understand mathematical concepts and solve challenging problems that are not easily solved, but the problem can lead to curiosity. Productive struggle is a key component of students' learning mathematics with a conceptual understanding, and supporting it in learning mathematics is one of the most effective mathematics teaching practices. In comparison to research on students' productive struggles, there is little research on preservice mathematics teachers' productive struggles. Thus, this study focused on the productive struggles that preservice mathematics teachers face in solving a non-routine mathematics problem. Polya's four-step problem-solving process was used to analyze the collected data. Examples of preservice teachers' productive struggles were analyzed in terms of each stage of the problem-solving process. The analysis showed that limited prior knowledge of the preservice teachers caused productive struggle in the stages of understanding, planning, and carrying out, and it had a significant influence on the problem-solving process overall. Moreover, preservice teachers' experiences of the pleasure of learning by going through productive struggle in solving problems encouraged them to support the use of productive struggle for effective mathematics learning for students, in the future. Therefore, the study's results are expected to help preservice teachers develop their professional expertise by taking the opportunity to engage in learning mathematics through productive struggle.

This single-blinded, nonequivalent control group pretest-posttest study was undertaken to evaluate the effectiveness of simulation education on clinical judgement, collaboration, communication skills, and perceived education practices and simulation design characteristics among student nurses in Korea. Participants were 47 students (19 in the experimental group and 28 in the control group) recruited by convenience sampling. The simulation based clinical reasoning education consisted of seven weekly, 120-minute high fidelity simulations. All participants completed the pretest and 7-week post measurements of a clinical judgment, collaboration, and communication skills with 4-week post measurement of collaboration, and participants in the experimental group provided a measurements of perceived education practices and simulation design characteristics. Data were analyzed using repeated measured ANOVA, and mixed linear model with SAS 9.2. Significant improvements were found in the experimental group for clinical judgment, collaboration, communication skill, and perceived education practices and simulation design characteristics. The study results show the impact of the perceived education practices and simulation design characteristics on facilitating the effectiveness of simulation education. The findings suggest a feasible and sound teaching method for student nurses and the need for further studies with a larger sample.

One's Clothing Satisfaction, has a great influence on his role behavior in a society. Especially, as for the teacher's and the professors whose role is teaching, it can not be too emphaszed. Above all, high school girls and college women are the most likely to be influenced by their teachers' clothing behavior, to whom they pay their respect in every way. From this point of view, this study was aimed at explaining, the correlation between the teachers/professors' clothing behaviors and the learning efficiency. On clothing behaviors assessed 30 items related with the learning efficiency, selected from the instruments of preceding studies, and modified by the factors dealing with modesty, color, and design. The questionnaires were composed of two major categories: those for students and for teachers/progessors. The subjects of this study were included students and teachers/professors of high school and universities in Seoul. The data were analyzed statically by mean, standard Deviation, and F-test. The results of this study were summerized as follows; 1. The clothing behaviors of the teachers/professors influenced on the learning efficiency. Namely teachers' clothing satisfaction is in direct proportion to them teaching efficiency and students' learning efficiency. 2. Among the clothing behavior variables, modesty had a great influence on the learning efficiency, especially as for that of teachers more than professors. 3. The influence of the teachers'/professors' clothing behaviors on the learning efficiency showed no significance between high school girls and college women, but some significance between the grades of collegians. 4. As for the teachers'/professors' clothing behavior, male teachers/professors gave priority to design and female teachers/professors to modesty, color showed no significance between them irrespective of age. 5. As for the clothing behavior variabels, both the teachers/professors and the students showed some significance. In class the teachers/professors highly responded to their own clothing behaviors than the students. 6. According to priority the most favorable clothing colors for male teachers/professors are navy blue, gray, indigo blue, and black, and the most disgusting ones red, mud yellow, violet, pink, and green. The most favorable clothing colors for female teachers/professors are beign, white, pale yellow, and black, and the most disgusting ones red, mud yellow, and yellow and yellow according to priority. It is that teachers/professors should wear modestly and in color harmony to invite the desirable students' will to study. Teachers'/professors' colorful appearance and heavy toilet bring about a drop in the students' will to study.
