In this study, the educational effect was investigated by providing a teaching program so that pre-service chemistry teachers could apply model ignorance education to teacher training practice. The teaching program was constructed in consideration of the sensemaking concept proposed in the study of Odden & Russ and the process of teacher sensemaking proposed by Asli et al. The subjects of this study were 23 pre-service teachers in the 4th year of chemistry education department at a teacher training university in the central region of Korea. In order to form a sensemaking for the model's ignorance education, the teaching program consisted of four stages; the initial idea generation stage, cognition of model's ignorance stage in a inconsistent situation, the lesson strategy construction stage for model ignorance education, and lesson plan & practice stage during teacher training practice. In the first stage of this program, pre-service teachers' initial ideas about the Arrhenius model and Bronsted-Lowry model of acid-base reaction, and the electron transfer model of the oxidation-reduction reaction were investigated. In the second stage, inconsistant situation that cannot be explained by the knowledge of model was presented to recognize the ignorance of the model. The third stage was to develop the teaching ability of model's ignorance through textbook analysis and lesson strategy composition activities. As a final stage, during the teacher training practice, the pre-service teachers were asked to plan and practice the implementation of the model's ignorance education. Through the teaching program to form a sensemaking for ignorance education of the models, pre-service teachers had come to recognize the ignorance of the model, acquired ability to organize and execute lesson strategies reflecting model ignorance, and acquired recognition of the educational value and necessity of teaching the ignorance of models.

One of the main roles of the science teacher is to help students become active agents in their learning of science. This study described how an elementary science teacher used students' emotional resources to conduct emotionally responsive teaching and what were the learning outcomes of this approach. The participants of the study included the teacher himself and his 6^th grade students, and emotionally responsive teaching was applied in the science unit of 'Various Living Things and Our Human Lives'. Multiple types of data, including the teacher's teaching logs, video recordings of the lessons in the unit, and interviews with the students, were collected. The data were analyzed qualitatively, and the results were described using a self-study method. The teacher took advantage of three kinds of students' emotional resources (i.e., character drawing, t-shirt design, and raps) to organize his emotionally responsive teaching. The learning outcome included the students' positive emotions and active participation in science lessons, their epistemic practices such as explorations and justifications of knowledge, and the students' reconstruction of knowledge in consideration of their everyday lives. It was suggested that emotionally responsive teaching can promote elementary school students' active participation in science learning, resulting in meaningful learning outcomes in emotional, cognitive, and conceptual aspects. Further studies should thus be conducted to understand the characteristics of emotionally responsive teaching and its detailed teaching strategies.

In this study, I hoped to reveal the understanding of pre-service elementary teachers about proportional reasoning and the traits of proportional reasoning strategy used by pre-service elementary teachers. The results of this study are as follows. Pre-service elementary teachers should deal with various proportional reasoning tasks and make a conscious effort to analyze proportional reasoning task and investigate various proportional reasoning strategies through teacher education program. It is necessary that pre-service elementary teachers supplement the lacking tasks such as qualitative reasoning and distinction between proportional situation and non-proportional situation. Finally, It is suggested to preform the future research on teachers' errors and mis-conceptions of proportional reasoning.

This study was on autobiographical traditions, in particular, autobiographies of teachers. First, autobiographical method was suggested as a kind of qualitative inquiry on the teaching mathematics. Second, as a case of autobiographical method, autobiographies of an elementary school teacher were presented. In the case, the author of autobiographies was also a researcher. It showed the struggles of elementary school teacher to know and to practice her teaching mathematical patterns. Autobiographies of teachers can be used as good sources for reflection of teachers, and also as a method for teachers education. And then, for communicating with teaching strategies among teachers in communities, they can be used. One the other hand, autobiographies of teachers can be powerful materials for researches on teaching.

Professionalizing the teaching workforce has been recognized as one of the primary factors to reforming public education. In response to this challenge, it has been emphasized that an educational leader's role is to support professional learning communities more effectively. Although the academia of educational administration has increasingly drawn the significance of a teacher's professional development, understanding of an educational leader's role and contribution to this effort is quite limited and unclear. This article examines what factors and barriers affect teachers' participation in professional learning communities from the voices and experiences of teachers. The analysis found 1) identification, 2) autonomous will, 3) practical solution for factors to participation and 1) lack of theoretical foundation, 2) financial burden, 3) insufficient time for barriers to participation. In conclusion, the author suggests the strategies for an educational leader who has an important role in developing a teacher's professionalism: 1) create a strong network of university professors and other experts for career advice, 2) make an institutional effort to stimulate teachers' motivation to learn; 3) decrease the teachers' workload, 4) build a synthesized and consolidated system to establish communities.

This study analyzes the difficulties that student teachers, beginning teachers and experienced teachers face in the field of kindergarten, and urgent support requests. The total of participants was 372 of this number, 122 were student teachers, 118 were beginning teachers and 132 were experienced teachers. The results showed the difference in difficulties and the needed support requests among student teachers, beginning teachers and experienced teachers. Student teachers had the difficulty of time management, but beginning teachers and experienced teachers had trouble due to the nonexistence of assistant teachers. Student teachers required teaching strategies for starting relationships with children within responsibility. Beginning teachers and experienced teachers regarded the plan, practice, and evaluation of a program as the most needed support request. Collectively, the results revealed that expansion of the practice period is necessary for student teachers so that they can gain experience with children, parents, and the children's education institution with various opportunities as a learning course.

The purpose of the present study is to compare Korean EFL learners' speech corpus (i.e. oral productions) with their composition corpus (i.e. written productions). Four college students participated in the study. The composition corpus was collected through a writing assignment, and the speech corpus was gathered by audio-taping their oral presentations. The results of the data analysis indicate that (i) As for error frequency, young adult low-intermediate Korean EFL learners showed high frequency in determiners (mostly, indefinite articles), vocabulary (mostly, semantic errors), and prepositions. The frequency order did not show much difference between the speech corpus and the composition corpus; and (ii) When comparing the oral productions with the written productions, there were not many differences between them in terms of the contents, a style (i.e., colloquial vs. literary), vocabulary selection, and error types and frequency. Therefore, it is assumed that the proficiency in oral presentation of EFL learners at this learning stage heavily depends on how much/how well they are able to write. In other words, EFL learners' writing and speaking skills are closely co-related. It implies that the teacher does not need to separate teaching how to speak from teaching how to write. The teacher may use the same methods or strategies to help the learners improve their English speaking and writing skills. Furthermore, it will be more effective to teach writing before speaking since they have more opportunities to write than speak in the EFL contexts.

In this study, we discuss pedagogical content knowledge (PCK) of pre-service environment teachers since PCK is one of the most important professional competencies for teachers. In Republic of Korea, environmental education is taught as an independent subject in middle and high schools. Thus, pedagogical content knowledge (PCK) of environment teachers plays an important role for quality EE at schools. The purpose of this study is to find out the PCK(Pedagogical Content Knowledge) of pre-service environment teachers. Researchers collected and analyzed data from four environmental education department. Study method used a questionnaire for eighty-two pre-service environment teachers. The study results are as follows. Seven part of PCK(Knowledge of Instructional Strategies, Knowledge of Representation, Knowledge of Subject Matter, Knowledge of Evaluation, Knowledge of Students, Knowledge of Curriculum, Knowledge of Environmental Context) exists the significant difference in pre-service environment teachers. The highest part is the Knowledge of Environmental Context and the lowest part is the Knowledge of Evaluation in pre-service teachers. So the curriculum of environmental education department will be changing that emphasize the Knowledge of Evaluation and the Knowledge of Students.

The purpose of this study is to reconceptualize the homeroom management and classroom management for secondary school teachers. The result of the study is as follows: First, the homeroom management that has been usually miss-presented as 'classroom management' in Korea is the concept comprizing the elements of homeroom management and those of teaching management together. Second is the re-conceptualization of classroom management. As the sub-concepts of classroom management, the homeroom (classroom) management and the teaching (classroom) management are also suggested. The classroom management is defined as 'the conduct or ability to accomplish the educational activities successfully'. Meanwhile, the homeroom (classroom) management is defined as 'the homeroom teacher's conduct or ability to successfully accomplish the educational activities for class students' and the teaching (classroom) management as 'the subject teacher's conduct or ability to successfully accomplish the educational activities for the class'. Therefore, the teachers are asked to have the ability for classroom management - that is, both the homeroom (classroom) management ability as the homeroom teachers and the teaching (classroom) management ability as the subject teachers. Based on the results, this study suggests some school policies such as the sharing of effective classroom management strategies through the change of teachers' culture and the improving of working environment for better concentration to the classroom management.

For preservice teachers' instrumental-to-relational pedagogical content knowledge transformations, this research designed several didactical tasks based on Kinach's cognitive strategies. The researcher identified preservice teachers' understanding about what is a definition and how to teach it. By challenging their fixed ideas about definitions, the researcher could motivate them to embrace the new teaching approach which guides reinvention of definitions. The PCK development was not the simple process of filling their tabular rasa PCK with theories of mathematics education, but the dialectical process of identifying, challenging, changing and extending preservice teachers' existent PCK. This research will contribute to explore new directions of mathematics teachers' PCK development and the method of teacher education.
