This was to investigate how the slow learners who specially belonged to low-SES, or North Korean defectors showed their errors in mathematical learning. To conduct the study, two groups for each minority group participated in the study volunteerly during the Winter vacation, in 2011. Based on the preliminary interviews, a total of 15 units were given, focusing on building mathematical basic concepts. As results, they had some errors in common. They both were in lack of understanding of the terminologies and not able to apply the meanings of definitions and theorems to a problem. Because of uncertainty of basic knowledge of mathematics, they easily lost their focus and were apt to make a mistake. Also, they showed clear differences. North Korean defectors were not accustomed to using or understanding the meanings of Chines or English in Korean words in expressing, writing mathematical terminologies and reading data on the context. Technical errors, and misinterpreted errors were found. However, students from the low SES showed that they were familiar with mathematical words and terminologies, but their errors mostly belonged to carelessness because of the lack of mastering mathematical concepts.

The reason why creativity becomes the important subject in 21th century is that it does an important role which solves many problems surrounding our whole life in this internationalization, globalization, knowledge-information age. But scholars who formerly researched the creativity-field explain the necessity of creativity with the internal and fundamental reasons. That is, scholars say that creative activities produce originative products and originality itself. And it is the root of which will be able to discover meaning of life and it -creativity - is successive activities that is demanded when individual life want to obtain important value by expressing one's inner world to the outside using creative resource. Recently, with the trends of present age and the educational needs, research about creativity is actively carried out and it draws out the results that creativity can be developed and enhanced through education and training. So, now many researches have focused on how to develop the creativity. Investigating those researches, we found that the recent issues of researches on creativity were changing and now they focused on creative instruction methods and behavioral factors. Especially, they were selected as the subject related to the creative education - creative instructional method and program, atmosphere in classroom, and factors of teacher. It means that the past researches which were a little bit conceptive have been changing to material ones which will be able to enhance creativity and its effect. So, in this research, we have developed the program for CPS(Creativity Problem Solving) and verified its effect.

This study started from the basis of necessity on the researches which asserts that parental rearing behavior in the modern society should change reflecting the social change of sociocultural environment. For this, parental rearing behavior of social constructivism and existing parental rearing behavior were contemplated while construct of parental rearing behavior was explored on the basis of main causes from Vygotsky's theory in order to prepare paradigm of new parental rearing behavior. As far as the method of study goes, various literature from relevant scholars were analyzed, centering various previously conducted studies pertaining to parental rearing behaviors as well as Vygotsky's theory. Also, the validity of the contents was confirmed through consult and revision from three experts. As the result, five factors were extracted. First, factor of cooperative interaction on social interaction. Secondly, emphasis on Internalization factor on social constructive behavior. Thirdly, potential development factor in zone of proximal development. Fourthly, instructional conversation factor as semiotic medium. Lastly, assistance factor as scaffolding. As a result, new paradigm of parental rearing behavior was presented and opened a prospect in developing the touchstone of parental rearing behavior pursuant to social constructivism.

In order to explore the influences of coteaching through mentoring upon the teaching professionalism of beginning science-gifted education teachers, this case study deeply investigated the change processes in the aspects of pedagogical content knowledge (PCK). Two beginning teachers planned, performed and reflected together their science instructions for science-gifted students in secondary school during four 3-hour classes. Since the second instruction, pre-, during-, and post-mentoring were conducted, we collected various data related to teachers' planning processes, videotaped all coteaching science classes, and wrote field notes. We also recorded in-depth interviews with the teachers and the whole process of mentoring. All the data were analyzed by using the constant comparative method. The results of the analyses indicated that coteaching through mentoring positively changed the teachers' PCK. Above all, we found that coteaching and mentoring strategies generated a significant synergy effect through a mutually complementary relationship. The teachers developed deep practical knowledge about the enrichment curriculum, which placed more emphasis on developing cognitive and/or affective characteristics of science-gifted students. The teachers also improved their knowledge about the characteristics of science-gifted students and the instructional strategies appropriate for developing them. Moreover, practical knowledge about assessment domains and methods used in science-gifted education were improved. Knowledge on science content necessary for effective inquiry instruction was also improved.

The purpose of this study was to analyze pre-service teachers' reflective discussion on their practical work-based teaching by focusing on the components of instruction and the connectivity of discussion. Eight after-class discussions were recorded and transcribed, and finally analyzed in terms of theoretically driven categories such as aims, teacher knowledge and learner response which also respectively reflect the actual flow of planning, implementation and evaluation of the teaching practice. The result showed that in their discussion about students, conceptual understanding and scientific skill components were most emphasized, while teaching method and strategy were most frequently addressed in the discussion about teacher knowledge. But this also revealed problems in their discussions such as the lack of discussion about inquiry and student interest, difficulties in clarifying theoretical terms and the lack of discussion about instructional models and theories. Meanwhile, pre-service teachers' discussions were limited in terms of connectivity between the components of instruction, meaning that their discussion tended to deal with each component separately rather than occurred in connection with each other. Furthermore, when connections were made during the discussion, only few components of instruction appeared. Based on this result, the paper suggests the need to develop tools to facilitate effective reflection in ways that incorporate various components of instruction and enhance connectivity between the components and between the instructions.

The purpose of this study is to investigate how to strengthen the formation of relationship competence through the lesson in the housing of the 2015 revised Technology Home Economics curriculum. In order to achieve this goal, we analyzed curriculum documents, achievement standards of curriculum, achievement standards of assessment, and assessment standards of the 2015 revised Technology Home Economics curriculum. Then, we analyzed whether or not the curriculum could be truly reflected in the school site by comparing and analyzing verbs of the assessment standards and curriculum content system. In addition, we suggested the plan to ensure that 2015 revised curriculum can be implemented well by proposing a method of teaching-learning and assessment standards to cultivate the formation of relationship competence among the housing lessons. The results of the study are as follows. First, the 2015 revised Technology Home Economics curriculum are categorized into three subject competences according to the content, but eventually show the content is not mutually exclusive with the three subject competences. It can be said to demonstrate the characteristics of human ability development, that is, one learning can't be related only to one competency. Second, it is difficult to reflect the assessing subject competencies system in school education, where evaluation is carried out based on the assessment standards. This is because the skills of the 2015 revised curriculum documents are partially reflected in the assessment standards. Therefore, this study shows that teachers need to cultivate various subject competencies. In order to overcome the fundamental limitations of the competency-centered curriculum, it is necessary to retrain the teachers as well as to improve teaching and learning methods for operating the curriculum.

Identifying students' achievement level and reflecting it on educational policy making or instructional improvement by analyzing the results of nationwide standardized assessment is an integral part of accountability in education. On the basis of this premise, we analyzed the characteristics of National Assessment of Educational Achievement (NAEA) items for middle school science subject conducted from 2010 to 2013 by using the option response rate distribution curve, the fittest graph estimated from the response rate of correct/incorrect options by achievement score. Furthermore, we classified the type of option response rate curve in terms of correct and incorrect options. Results of the analysis of option response curve showed that five types of correct option response curve (S-shaped, J-shaped, straight-shaped, F-shaped, and step-shaped) and 4 types of incorrect option response curve (down-slope, flat, mound, and up-slope) were identified. The most common type of items was the combination of S-shaped correct option response curve and down-slope incorrect option response curve, which are considered as appropriate items to discriminate the students according to achievement level. Moreover, correct option response was found to be correlated with incorrect option response. Based on the results, we also discussed some implications on teaching-learning method and classroom assessment in science education.

This study investigated the changes in teaching professionalism of beginning science-gifted education teachers through mentoring in the aspects of pedagogical content knowledge. We selected two beginning teachers whose teaching careers in science-gifted education were less than five years. The teachers planed, performed and reflected on science instructions for secondary science-gifted students through mentoring during nine class hours over three times respectively. We observed their instructions and analyzed the taped videos, the materials, the transcripts for in-depth interviews with mentees, and discussions between mentor and mentee, researcher's field notes by using the constant comparative method. This study revealed that the mentoring, although there were many limitations, positively changed the mentees' practical knowledge about the curriculum for science-gifted education, the instructional strategies for science-gifted education, the assessment in science-gifted education, the science-gifted students, and the science content. These results suggest that the mentoring will be useful in improving the teaching professionalism of beginning science-gifted education teachers and provide meaningful implications in finding the ways to use it effectively in science-gifted education.

This study clarified the big ideas related to teaching addition and subtraction of fractions with different denominators based on quantitative reasoning with unit and recursive partitioning. An analysis of this study urged us to re-consider the content related to the addition and subtraction of fraction. As such, this study analyzed textbooks and teachers' manuals developed from the fourth national mathematics curriculum to the most recent 2009 curriculum. In addition and subtraction of fractions with different denominators, it must be emphasized the followings: three-levels unit structure, fixed whole unit, necessity of common measure and recursive partitioning. An analysis of this study showed that textbooks and teachers' manuals dealt with the fact of maintaining a fixed whole unit only as being implicit. The textbooks described the reason why we need to create a common denominator in connection with the addition of similar fractions. The textbooks displayed a common denominator numerically rather than using a recursive partitioning method. Given this, it is difficult for students to connect the models and algorithms. Building on these results, this study is expected to suggest specific implications which may be taken into account in developing new instructional materials in process.
