본 연구는 교사와 학생의 가치의 변화 양상을 분석하기 위해 수학학습 가치 설문지를 활용하여 15차시 수업이 진행되는 과정에서 학생들과 교사의 가치를 4차에 걸쳐 분석하였다. 그 결과 가치는 개인이 수많은 경험을 거쳐 내면화된 깊이 있는 판단 양식임에도 불구하고 수업이 진행됨에 따라 많은 변화가 나타났다. 교사는 자신이 중요하게 생각하는 가치를 무조건 강요하기 보다는 학생들이 무엇을 중요하게 생각하는지를 반영하여 자신의 목표를 수정해 나갔다. 수학적 가치의 경우, 합리주의, 객관주의, 미스터리는 교사와 학생이 서로 수렴하였고, 통제는 일관되게 유지되었으며, 개방의 경우 교사와 학생모두 상향 하였다. 수학 교육적 가치의 경우에는 이해, 즐거움, 용어, 적용의 경우 서로 수렴하였고, 성취는 일관되게 유지되었다. 또한 교사는 효과적인 수업으로 나아가기 위해 끊임없이 학생과의 가치에 대해 협상해 가면서 몇 가지 전략을 사용했다. 이러한 연구 결과를 바탕으로 진정한 의미에서 학습자 중심수업으로 나아가기 위한 한 가지 방안으로 가치가 중요한 요인이 될 수 있다는 시사점을 제공하고자 하였다.

본 연구는 개인의 소명의식이 자신뿐만 아니라 상호작용하는 타인에게도 영향을 미칠 수 있다는 선행연구를 바탕으로 학생이 지각한 교사의 소명의식이 학생에게 미치는 영향을 살펴보고자 하였다. 구체적으로 학생이 지각한 교사의 소명의식이 학생의 안녕감에 미치는 영향과 그 메커니즘을 알아보기 위해 대한민국 고등학생 494명을 대상으로 설문을 실시하고, 학생이 지각한 교사의 소명의식과 학생의 안녕감의 관계가 정서적 지지와 적응적 인지적 정서조절전략에 의해 매개되는지를 구조방정식 모형 검증을 통해 살펴보았다. 그 결과, 학생이 지각한 교사의 소명의식은 정서적 지지를 매개하여 학생의 안녕감에 정적인 영향을 주는 것으로 나타났다. 또한, 학생이 지각한 교사의 소명의식은 정서적 지지를 매개하여 학생의 적응적 인지적 정서조절전략의 사용을 높이는 것으로 나타났으며, 정서적 지지는 학생의 적응적 인지적 정서조절전략을 매개하여 학생의 안녕감 수준을 높이는 것으로 나타났다. 마지막으로, 학생이 지각한 교사의 소명의식이 안녕감에 영향을 미치는 경로에서 정서적 지지(매개변인 1)와 적응적 인지적 정서조절전략(매개변인 2)의 순차적 매개효과가 유의하였다. 이와 같은 결과를 바탕으로 연구의 이론 및 실무적 함의, 한계점 및 후속 연구에 대한 제안을 논의하였다.

This study is research on physical health and mental health(physical and mental symptom at school) in perceived school environment among adolescents. The study subjects ere selected by senior high school students in seoul and random sampling. The 3,060 subjects were selected 18 schools. The duration for survey was for Nov. 25-Dec. 13, 1998. The reliability of Questionnaire was Cronbach's $\alpha=0.95$. This study used multiple regression through Factor Analysis in SPSS programs. The major findings of this study are as follows: (1) All of Multiple Regression Models were significant. (p<0.001). (2) Physical Mental health is related to gender, personal environment, and economic status. (3) Physical Health is related to perceived school environmental variable (therapeutic teacher-student relationships, classrom climate, and school life satisfaction) among adolescents. (4) Mental Health is related to perceived school environment variables(therapeutic teacher-student relationships, classroom climate, school life satisfaction, teachers' climate, and classmates' attitudes) among adolescents. This study could be used as the basis for the development of educational program, counseling, teacher in-service training, student teacher training and the establishment of educational and health policy.

학생들의 학업 성취에 교사가 결정적인 역할을 한다. 본 연구는 학교 현장에서 이루어지고 있는 과학 수업을 과학 예비교사들이 분석하였다. 과학 교사의 수업을 분석 위한 검사 도구는 수업, 학생 행동, 교사 행동, 발문의 4가지영역으로 구성되었다. 100명의 과학 교사의 수업을 예비 교사들이 참관한 것을 분석하였다. 그 결과, 예비교사들은 과학 교사의 수업은 탐구 중심으로 이루어지지 못하고 있는 것으로 분석하였다. 교사의 성과 연령의 특성에 따라서 과학 수업에 통계적인 차이가 없는 것으로 분석되었다. 또한, 과학 수업이 개념 중심 그리고 교사 중심으로 수업이 이루어지고 있음을 분석하였다.

This study focuses on student engagement in Chinese middle school mathematics classrooms. By the recording and quantitative analysis on video case, this study explored the main acts and time of student engagement. The data showed that among the student engagements: (1) Students' responses to teacher's question occurred most frequently; (2) Collective responses were much more than the individual responses; (3) Students' responses and classroom practice spent the longest time; (4) The most frequent student engagements occurred in the aspects of classroom practice; and (5) Students rarely asked a question to teachers. The study also suggested that teacher's effective guidance could improve the level of student engagement and the content of classroom practice is very important to the quality of student engagement.

This study investigates student teacher's recognition of professionalism as they relate to self-concept and conflict. Subjects were 190 student teachers in Seoul and Gyeonggi Province. Subjects responded to self-report questionnaires. Data were analyzed by regression analysis using the SPSS computer program. The Major result of this study are as follows : First, there were significant positive relationships between self-concept and recognition of professionalism in four sub areas. Second, there were also significant negative relationships between conflict and recognition of professionalism in four sub areas. Consequently, self-concept and conflict were statistically significant factors in predicting student teacher's recognition of professionalism.

This study gives opportunity for investigating how student teachers view the teaching profession and how they transfer their pedagogical knowledge into practice. The aim of the study is to investigate the teaching skills student teachers gained in the assessment of micro teaching of their peers. The participants are 30 mathematics student teachers enrolled in the teacher training program in a state university. Document analysis and semi-structured interviews are the research instruments and inferential & descriptive statistics are used for the data analysis. The findings suggest that the qualitative and quantitative peer assessments of student teachers were graded differently which results from the difference of perceptions about teaching and different conceptualizations of the teaching qualifications.

Proof serves a critical role in mathematical practices as well as in fostering student's mathematical understanding. However, the research literature accumulates results that there are not many opportunities available for students to engage with proving-related activities and that students' understanding about proof is not promising. This unpromising state of instruction of proof calls for a novel approach to address the aforementioned issues. This study investigated an instruction of proof to explore a pedagogy to teach how to prove. The teacher utilized the way of problem posing to make proving a routine part of everyday lesson and changed the classroom culture to support student proving. The study identified the teacher's support for student proving, the key pedagogical changes that embraced proving as part of everyday lesson, and what changes the teacher made to cultivate the classroom culture to be better suited for establishing a supportive community for student proving. The results indicate that problem posing has a potential to embrace proof into everyday lesson.

Most state-of-the-art CNNs for action recognition are based on a two-stream architecture: RGB frames stream represents the appearance and the optical flow stream interprets the motion of action. However, the cost of optical flow computation is very high and then it increases action recognition latency. We introduce a design strategy for action recognition inspired by a two-stream network and teacher-student architecture. There are two sub-networks in our neural networks, the optical flow sub-network as a teacher and the RGB frames sub-network as a student. In the training stage, we distill the feature from the teacher as a baseline to train student sub-network. In the test stage, we only use the student so that the latency reduces without computing optical flow. Our experiments show that its advantages over two-stream architecture in both speed and performance.

Conducted as an ethnographic examination of science teaching and learning in an Innovative Middle School in Korea, this study employs sociocultural theory to examine how structures afford and limit student participation in an innovative school designed to promote student-centered learning. Data includes teacher and student interviews, student responses to a questionnaire, classroom observations, and analysis of video recordings of ten lessons in two in two 8th grade science classes. Using structure|agency dialectic theory, we identify and describe some structures that afford and limit teacher and student agency at the micro (science classrooms), meso (school), and macro (Korean society) levels to raise some questions about current reform measures, such as innovation schools, that seek to position classroom teachers as agents for change in science education reform in Korea. Findings suggest that while teachers and school administrators play an essential role in structuring learning opportunities at the meso and micro levels, they have limited agency to address structural constraints originating at the macro-level, which can negatively impact teaching and learning in the science classroom. We offer implications for policy and practice and argue the need for more qualitative research, informed by sociocultural theory, to inform science education reform efforts in Korea.
