In this study, the types and the characteristics of students' responses to anomalous data were investigated. The criteria for classifying students' responses were 'acceptance of validity of anomalous data', 'acceptance of inconsistency between anomalous data and initial theory', and 'change of belief in initial theory'. Seven types of responses were identified as follows: Rejection, reinterpretation, exclusion, uncertainty, peripheral theory change, partial belief change, and theory change. Absolute belief in the intial theory and doubts about methodological accuracy were found to be the major reasons for rejecting anomalous data. The students did not accept the inconsistency between anomalous data and initial theory because they ignored the experimental procedures and focused on the similarity of the experimental results.

This study considered Elementary school textbook and teacher's manual in Korea in terms of theories on counting. First we considered the meaning of counting in elementary school mathematics based on many preceding researches. And we compared textbooks in Korea with foreign textbooks in Singapore, China, USA. As a result, compared with Korea, these foreign textbooks reflect the theories on counting more actively. First of all, they consider counting to be an important basis for the four operations. Teacher's manual in Korea introduces the theories on counting, but the content was limited and thread was not clear. Based on these consideration, We discussed reflection of elementary school textbook in terms of theories on counting.

This article explores early childhood teachers' practices from bottom-up perspectives on the relationship between theory and practice. Results of the review of literature are as follows: 1) From top-down perspectives early childhood teachers' practices and their classroom behaviors have been traditionally defined within the framework of theories of child development, the notion of developmentally appropriate practice, and designed program models; 2) From bottom-up perspectives researchers have a focus on how teachers' practices lead theories and how they construct the act of teaching through reflective thinking; 3) empirical research on preservice and inservice teachers demonstrates that preservice teachers develop their own theories of teaching from their previously held assumptions, gained knowledge from preparation programs, and their individual experiences. It also shows that inservice teachers construct teaching through their implicit knowledge and the use of strategies to negotiate problems. Implications for future studies on teachers's practices are discussed.

There are so many research literatures on conceptual change theory and the nature of concepts such as p-prims, mental model, ontological belief, and cognitive structure. Conceptual change means learning (Vosniadou, 1999; Duit;1999). It is necessary to review and elaborate existing conceptual change theories in order to explain the learning process and its implications. Therefore, we derived from reviewing literatures that learners construct new conceptual structure in response to given contexts at the same time activating their beliefs. We reviewed some mental theories that integrated cognitive and affective components and were based on framework/specific theory or information processing theory. We suggest learners' framework of conceptual structure and conflict model of conceptual structure. We expect to obtain effective ways of science teaching and learning and implications for cognitive conflict and conceptual change from using conceptual structure later.

This study investigeted secondary math teachers' difficulties of technology in geometry class with grounded theory by Strauss and Corbin. 178 secondary math teachers attending the professional development program on technology-based geometry teaching at eight locations in January 2014, participated in this study with informed consents. Data was collected with an open-ended questionnaire survey. In line with grounded theory, open, axial and selective coding were applied to data analysis. According to the results of this study, teachers were found to experience resistance in using technology due to new learning and changes, with knowledge and awareness of technology effectively interacting to lessen such resistance. In using technology, teachers were found to go through the 'access-resistance-unaccepted use-acceptance' stages. Teachers having difficulties in using technology included the following four types: 'inaccessible, denial of acceptance, discontinuation of use, and acceptance 'These findings suggest novel perspectives towards teachers having difficulties in using technology, providing implications for teachers' professional development.

Many researches have reported that it is difficult to solve students' difficulties in learning science with teaching models focused on certain aspects because of various reasons. Recently, in science education research, the integrated perceptive has been to put emphasis on understanding complex situations of real teaching and learning. In this research context, the integrated mental model theory that were considered as a whole factor related to learning has been studied by integrating previous studies that related to students' conceptions and learning in various fields. Thus, it is needed that the teaching model be based on the integrated mental model theory to help students to solve their difficulties. The purpose of this research was to develop a new teaching model based on the integrated mental model theory to address this issue. We reviewed current studies on student difficulties and teaching models. After this, we developed 4M learning cycle teaching model. In this paper, we described the process of developing a new teaching model and discussed how to apply this teaching model to the practices. We also discussed the effects of 4M learning cycle teaching model based on the integrated mental model theory in learning science with its implications.

The aims of this study are to investigate how Kepler found a scientific problem for the retinal image theory and how abductive reasoning was used in his theory development, and to find implications for teaching creativity in science class from his thinking processes in the scientific discovery. Through the analysis of the related literatures, it was found that Kepler's problem finding in his retinal image theory came from the critical analysis of contemporary theories of vision, based on his relevant knowledge of optics, as he formulated his own hypothesis to build a new theory in eye vision employing optical phenomenon in spherical lens, which is a kind of abductive reasoning. From the results, three suggestions are proposed, that: (a) in the development of creativity teaching material, the situations like Kepler's problem finding need to be included in the programs; (b) it should be taught that relevant scientific knowledge is important for problem finding and hypothesis formulating; and (c) the experience of successful problem solving by themselves could help them find new scientific problem(s).

This thesis presents the methods and tool development of performance assessment as final stage for information literacy instruction of teacher-librarians. The evaluation is an important part in information literacy instruction of teacher-librarians in the school libraries. But until now, there is little research on evaluation methodologies in the instructional activities of teacher-librarians. There is only evaluation domain presented in the primary and secondary 'Information and the Library' curriculum. To develop an evaluation model as a base for measuring performance assessment related to teacher-librarians is important. The goal of this thesis is to provide teacher-librarians with basic principles to develop many kinds of performance assessment tools in their own instructional activities.

2005년 1월, 정부혁신지방분권위원회의 ${\ulcorner}$국가통계인프라 강화 방안${\lrcorner}$ 의 내용을 보면 통계청의 지방통계사무소를 지역통계센터로 개편하여 지역통계의 기획, 표본설계 등에 관한 기술지원을 담당하는 것으로 기술되어 있다. 향후 모든 기관의 통계조사업무를 수탁, 대행하는 기관으로의 발전을 목적으로 한다. 통계청에서는 이 역할을 담당할 인재를 양성하기 위한 교육과정을 통계교육원에 요청하여 개설한 바, 상반기와 하반기 2회 실시하였다. 교육과정명은 ${\ulcorner}$통계개발기획과정${\lrcorner}$ 으로 2주간 실시하였고, 교육대상자는 현재 지방청 및 지방사무소에 근무하는 직원으로 한정하였다. 교육과목으로는 이론과 실무가 접목되고, 교육 이수 후에 바로현장에서 활용 가능하도록 구성하였으나 결과론적으로 보았을 때 추가되어야 할 교육내용들이 나타났다. 조사기획 즉, 조사방법과 조사기획서 작성에 치중한 교육내용은 향후 지역통계센터에서 어떤 역할을 부여받느냐에 따라서 좀 더 체계화되지 않을까 생각된다. 전체 팀원들을 위해서는 일련의 조사기획에 대한 이론과 실무경험이 중요하다. 또한 지방자치단체의 통계DB구축에 도움을 주기 위해서는 그 부분에 대한 이해도 필요할 것으로 판단된다. 특히 관리자에게는 리더십과 관리능력 그리고 대인과의 커뮤니케이션 스킬, 분석능력 등이 추가적으로 필요할 것으로 생각되었다.
