The purpose of this study was to investigate the changes in teachers' recognition of science class and children for the gifted, and the process of changes in their practical knowledge after the experience of science class and conversation with colleague teachers. Two elementary teachers, teacher A and B, were selected as subject of investigation, who wanted to improve their science class. They experienced the process of self-examination during their class and from class conversations. Teacher A has 10 years of teaching experience. She has been in contact with gifted children and observed them since undergraduate. She entered the graduate school since she came to be interested in science class and children for the gifted. While teacher B has only three years of teaching experience and had a first contact with the gifted after graduate school. The results of this study are as follows. Teacher A didn't change recognition of gifted children class by class conversation in short term because she had a firm faith in good class teaching and was rich in class teaching knowledge. And, her practical knowledge was applied to the next class by changing teaching method or by supplementing her class contents in concerned part through class observation and class conversation with her colleagues. Teacher B was characterized as being lack of class confidence and concerned more about subject knowledge. She was forming a new practical knowledge along with new class teaching knowledge. Teacher B was in trouble with applying new practical knowledge to next class. From such findings, it was concluded that the process of changing or forming of practical knowledge depends on the beliefs, values, experiences, or knowledges of each teacher. A reflection on one' own class teaching could be a good way to form a practical knowledge and improve teaching speciality, when it was concerned with self-reflection of their own class, class observation, and communication with colleagues. Thus, the reflection practice could be applied to the teaching program of teachers for the gifted to form practical knowledge through trial class, self-reflection of class, and conversation with colleagues.

On the standards or elements of teaching evaluation, the Korea Institute of Curriculum and Evaluation(KICE) has carried out the following research such as : 1) development of the standards on teaching evaluation between 2004 and 2006, and 2) investigation on the elements of Teacher Knowledge. The purposes of development of evaluation standards for mathematics teaching through those studies were to improve not only mathematics teachers' professionalism but also their own teaching methods or strategies. In this study, the standards were revised and modified by analyzing the results of those studies focused on the knowledge of subject matter knowledge, knowledge of learners' understanding, teaching and learning methods and assessments, and teaching contexts. For this purpose, according to those evaluation domains of each teacher knowledge, elements on teaching evaluation focused on the teacher's knowledge were established using the instructional evaluation framework, which is developed in this study, including the four areas of knowledge obtaining, instructional planning, instructional implementation, and instructional reflection. In this study, 1st and 2nd pilot studies was accomplished for revising evaluation standards and as a result, the procedure for implementing mathematics teaching using evaluation standards was changed to evaluate teachers own teaching using the standards focused on instructional reflection and according to the degree of satisfaction on reflecting their own teaching, standards on knowledge obtaining, instructional planning, instructional implementation would be utilized. Teacher survey is accomplished two times, by the subject of seven teachers. According ot the result of the first teacher questionnaire which was consisted of the essay type of questions on the degree of understanding the content of standards, the evaluation standards were revised. According ot the result of the second teacher questionnaire which was consisted of the essay type of questions on the application of standards, the evaluation standards were revised finally and the way of how to use the standards efficiently was suggested.

This study analyzed the learning effect, through a satisfaction survey and NVivo qualitative analysis, of fashion design classes using humanities self-reflection writing. The results are as follows. First, with regard to learning satisfaction, learners perceived the class as efficient and showed overall satisfaction. Second, learners' opinions were classified into self-reflection writing, design process, new experience of expression, and the understanding of class activities. Third, in self-reflection writing, learners discovered their tendencies and values while exploring their identity through deep thinking. Fourth, in the design process, learners set the design concept consistently through writing. Fifth, in the new experience of expression, learners recognized the idea produced through writing as the result of thought and considered it a new expression method for design. Sixth, in the understanding of class activities, learners were interested in the process and considered it an activity through which to build their own style in design expression. Design class activities using self-reflection writing drew a positive response and presented the possibility of educational use. The teaching method of this study is expected to be used as a humanistic method for expressions in various design fields.

This study examined the development of a teacher's teaching practice and identified argumentation-specific pedagogical content knowledge (PCK) and the influence of the argumentation-specific PCK on teaching practice in an argumentation classroom. The teacher has a Ph.D degree in science education, a 19-year teaching career, and no experience in instructing in an argumentation classroom. The developed program consists of nine lessons regarding photosynthesis for 7th graders. The teacher participated in a collaborative reflection with researchers after each lesson once a week and five times in total, which lasted for thirty minutes. All of the lessons were video- and audio-recorded and the transcript of lessons and collaborative reflection, pre- and post-survey related to argumentation, and researchers' journals were analyzed. Analysis of the data showed that the teacher emphasized group interaction showing utterances of listening, evaluating arguments, counter-arguing/debating, and reflecting on argument process after the fourth lesson although the teacher focused on individual argumentation showing utterances of talking, knowing meaning of argument, and justifying with evidence in the first three lessons. Also, the argumentation-specific PCK, which was identified with the understanding of students, nature of argumentation and argumentation task strategy, also influenced the development of teaching practice. The teacher comprehended the students' challenges in argumentation, developed her understanding of the nature of argumentation from an individual plane to social plane, and demonstrated a deep understanding of the task strategy by voluntarily joining in modifying the argumentation tasks.

The purpose of this study is to understand how a teacher's teaching can be changed while he or she teaches the same contents in different classes. The qualitative research method was used in this study. Data were collected from classroom observations, several in-depth interviews, and stimulated-recall interviews after each class. All the data were transcribed and analyzed interpretively, and then, the results of the analysis were checked by each participating teacher. The results are as follows: First, changes appeared in each class in terms of the teaching items, tools, sequence, and time, even though the same teacher taught the same contents. It showed that the teacher's teaching practice changed immediately and intuitively in class. Second, teachers tried to implement "exploratory teaching" or "move-testing teaching" to address the emerging problems during their teaching. They then reflected on and modified their own teaching. This type of change, which happened during the teaching practice, can be an example of "Reflection-in-practice." Thus, the results of this study can provide helpful insights into how teachers might adapt and reflect in their teaching. It suggests that teachers need to recognize their subconscious teaching changes and learn "Reflection-in-practice."

Reflection has been of interest to educators as Dewey discussed it. Information about how teachers interpret and analyze their students' learning would help us understand difficulties in teaching and learning. Moreover, it can be useful for teacher education by improving teaching methods. In this study, I investigated four U.S.A. mathematics teachers in a middle school. In this paper, I discussed Assess instances among the teachers' reflections on their students' thinking and changes of the reflections as time went by.

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.

The purpose of this study is to development of a teaching-learning model for active learning in engineering education. For this, the adequacy between educational objectives and active learning activities is verified and furthermore an "active learning teaching-learning model" is suggested. This suggested teaching-learning model is expected to supplement weakness of traditional lecture-type teaching-learning activity. Based on the literature review, first, the representative activities of active learning were derived. there are twenty active learning activities, which compose of five of individual learning activity, five of pair-learning activity and five of group-learning activity, and five of alternative- learning activity. In addition, a survey on adequacy between designed active learning activities and learning outcomes were conducted to ten educational experts. Lawshe's content validity calculation method was applied to analyze the validity of this study. Second, five teaching-learning principles, such as thinking, interaction, expression, reflection, and evaluation were derived to develop an "active learning teaching-learning model" which supplements lecture-type classes and then the "TIERA teaching-learning model" which consists of five stages was designed. Finally, based on the survey on educational experts, adequate active learning activities were proposed to apply in each stage of the "TIERA teaching-learning model" and as a result the TIERA model's active learning activities were developed. The result of this study shows that some activities of active learning are appropriate to induce high cognitive learning skills from the learners even in traditional lecture-type classrooms and therefore this study suggests meaningful direction to new paradigm of teaching-learning for engineering education. This study also suggests that instructors of engineering education can turn their traditional teaching-learning activities into dynamic learning activities by utilizing "active learning teaching-learning model".
