The goal of the study was to examine pre-service teachers' emotional experiences, especially during student teaching. The following questions guided this study. First, during student teaching, what are the characteristics of emotional experiences of pre-service science teachers? Second, what are used as the emotional rules and strategies by student teacher? In this study, we tracked nine pre-service science teachers over a four-week period of the student teaching. The data sources were lesson observations, interviews, emotional journals, and video-recorded classroom lessons. Results showed that student teachers experienced various 25 different types of emotions which were reported as the primary emotions of Koreans. The main subjects for interaction for positive emotions were students. For negative emotions, students, teachers and student teachers themselves all resulted in such negative emotional experiences. When the student teachers experienced negative emotions, they followed the emotional rule that their emotions should not be expressed in front of the students. Because of this, they tried various strategies for controlling emotions, such as 'understanding students', 'finding the positive side', 'seeing good students', 'ignoring', 'holding back', 'evading', and 'giving up'. Finally, suggestions for teacher education were discussed.

The purpose of this study is to examine the problems in the teaching practice of beginning science teachers who participated in the collaborative mentoring program to improve their teaching expertise. The participants were six beginning science teachers and six mentors at middle and high school levels. From each beginning science teacher and mentor teacher, journals, one-to-one mentoring records and transcripts, interviews and questionnaires, and transcripts conducted at the beginning, middle and the end of the mentoring program were collected. Seven aspects of the beginning science teachers' problems in their teaching practice were identified. The result showed that mentee teachers didn't set up specific learning objectives and they organized and presented lesson contents without considering students' proficiency level. Also, they found it hard to prepare for the lessons irrelevant to their major field of study and they tended to use convergent questions more than divergent questions. Mentee teachers tend to give teacher-centered rather than student-centered teaching. Beginning teachers' recognition of their problems in their teaching practice tends to lead changes in their teaching practice. Some of the problems that mentee teachers showed could be overcome if they recognized the problem through the collaborative mentoring program, but if not, it tends to remain throughout mentoring program.This study also highlighted the importance of reflection on beginning science teachers' practice.

The diversity of students is getting increased in the contemporary classroom. To deal with the diversity, differentiated instruction (DI) should be considered as a way of providing alternative approaches to content, process and product according to the students' readiness, interest, and learning needs. Teachers have problems and difficulties in supporting different student's needs. In fact, teachers need proven tools including framework, guidelines or computing systems to help to practice DI in real context. According to the activity theory, tools influence on how people act and think and even their social practice, playing a crucial role in mediating the activities with people. In DI practice, there are also some studies about physical and abstract tools, but they have been not widely utilized by teachers in real schools. It means that more innovative tool to promote DI might be required. Therefore, to design a better tool to mediate the DI activities with teacher, case studies were conducted. In order to elicit the design implications, two physical and two abstract tools for DI practice were analyzed as case studies. Through the analysis of the case studies, eight design implications better to facilitate DI practice were suggested. This study has implications in suggesting design guidelines for teachers' tools to facilitate their DI practice by analyzing case studies in DI practices for an innovative tool in the educational practice.

Research in teachers' knowledge for teaching mathematics (KTM) has been gradually growing for the past several years. With various conceptualizations about what teachers need to teach mathematics, there have been studies to find out the relationship between teachers' KTM and their students' achievement. In this paper, I reviewed various conceptualizations of teacher's mathematical knowledge for teaching, and existing qualitative and quantitative studies about this relationship. Based on the review, I identified the challenges to studying this relationship mainly focusing on the existence of a phase-teaching practice-between teachers' KTM and students' learning. Considering the challenges that have been identified in the literature review, I proposed topics for future studies that would contribute to our understanding how the teachers' KTMare related to their students' achievement, and investigate further about whether and how teacher-student interaction in classroom is related to changes in teachers' KTM.

The purpose of this study is to explore characteristics and limitations of a novice teachers's responsive teaching practice, who framed argumentation productively. One novice teacher and two eighth-grade classes participated in this study. Two of the small student groups with active teacher intervention were selected as focus groups. Students engaged in argumentation activity where they built an argument for hearing if the eardrum was torn. We recorded the class and interviews with the teacher and the students, which were transcribed for use in the analysis of the teacher's responsive teaching practices and epistemological, positional framing. We discovered that teacher thought that he should position himself as a facilitator to encourage students to present ideas clearly and to reach consensus. His framing was consistent in responsive teaching practices. Positioning himself as a facilitator, after he framed the discussion as idea sharing discussion by eliciting and probing students' idea, he framed the discussion as argumentative discussion by taking up students' idea and pointing out disagreement between them. As a result, members of small group 1 engaged in argumentative discussion and reached consensus. However, the teacher's productive framing did not guarantee students' productive argumentation practice. In small group 2, he did not elicit and probe students' ideas successfully. As a result, members of small group 2 did not engaged in argumentative discussions. He responded limitedly to the lack of students' conceptions because of lack of understanding about learners. Also, he mainly attended to students' reasoning, and not to students' framing about argumentation because he considered argumentation only as a tool for conceptual learning. The result of this study will contribute to the establishment of responsive teaching in science classrooms.

In this study, 27 pre-service teachers presented virtual mathematics instruction to develop his/her own teaching practice ability. I found several attributes in their virtual mathematics instruction such as connecting contents, asking justification, encouraging students' communication, representing variously, and using ICT etc. These will be the characteristics of the future mathematics class. When peer pre-service teachers assess presenter's instruction quantitatively, there are differences in the results between expert and pre-service teachers. Pre-service teachers didn't find the elements of student self assessment or group assessment and communication activities at the virtual instruction. When they assess peers' virtual instruction qualitatively, the results are specific or new ones compared with the quantitative assessment elements. Thus I suggested some implications for the mathematics pre-service teachers' virtual instruction in the view of teacher education.

This study tried to explore and understand the meaning, and the properties of noticing. The result of this study were first, the difference in mathematical noticing is distinguished in either the object which is paid attention is different or the object is same but differently interpreted or react. The cause of each difference could be described as mathematical objects such as conceptual objects and perceptual features. Second, teachers' teaching strategies, which narrow the gap in attention and play a key role in the formation of mathematical meaning, appeared in various places. This teaching strategy was implemented to distract students' attention. This study confirmed that the mathematical attention of teachers and students in math classes will differ depending on the object to which they pay attention, and that difference will be narrowed through teacher's discourse practice and teaching strategies through communication strategies.

The purpose of this research was to investigate the relationship between the change of beginning teachers' beliefs about a lesson and that of teaching practice and argument-based inquiry using science writing. Participants were three science teachers (A, B, and C) from different middle schools. Classroom observation and interview data were collected and transcribed for analysis. A Summary Writing test was also administered to examine whether there was an improvement in students' learning. The results indicated that the interaction between the teachers and their students developed, which is concluded as an improvement in the teaching practice. Teacher A and B also reported that teacher-student interaction had improved. Teacher A and C came to understand that argument-based inquiry using science writing classes constituted learner-centered instruction. The result from the Summary Writing Test showed the impact of the changes in teaching practice and in teachers' awareness of students' learning as well as produced meaningfully higher scores than compared groups on the rhetorical structure of all the specific areas in teacher A's school and on the scientific concept at B and C's schools.
