The purpose of this study was to investigate the change of teacher-student interaction in a beginner secondary science teachers' class through collaborative mentoring program. Three experienced science teachers as mentors and three beginner science teachers as mentees were participated in this study. Mentors have been teaching science secondary school for more than 13 years with specialty in science education, and mentees have been teaching less than three years in secondary schools. They were matched one-toone on grounded characteristics that were revealed from pre-interview. Data collection consisted of lesson plans of mentees' classes, videotaped lessons of mentees, consultation meetings between mentors and mentees, and interviews with mentees as well as mentors. The consultation meetings and interviews were audiotaped and then transcribed with the videotaped lessons. To examine the change in teacher-student interactions, the lesson observed after four sessions of mentoring was compared to the lesson before mentoring on the basis of the analytical framework that was developed based on the interpretative approach. The analytical framework addresses the four aspects of teacher-student interaction, which include beginner of interaction (initiation), the types of the question, the student response and the feedback. After four sessions of collaborative mentoring, the beginner science teacher's classroom interactions were initiated by students more often. Teachers' questions increasingly turned into thought-provoking queries that required higherorder thinking. The students responded in the form of statements instead of asking question more frequently. Also, teachers provided more delayed feedback than immediate feedback. These changes of interaction patterns showed that students took a leading role in classroom interaction and they were encouraged to think. From this result, we argue that the beginner science teachers developed the ability to make students think and to support them in coming to an understanding of knowledge through a collaborative mentoring program.

The students' feedback is important to measure and improve teaching performance. Many teacher performance evaluation systems are based on responses to closed question, but the free text answers can contain useful information which had to be explored. In this paper we present a lexicon-based sentiment analysis to explore students' text feedback. The data was collected from a system for the evaluation of teachers by students developed and used in our university. The students comments are in Romanian language so we built a Romanian sentiment word lexicon. We used this to categorize the feeback text as positive, negative or neutral. In addition, we added a new polarity - indifferent - in order to categorize blank and "I don't answer" responses.

The purpose of the study is to develop a science writing program for middle school students and to analyze the effects of this program. The program consists of twenty-one 10-minute long sessions in 2 chapters (stimulus and response; the structure and function of plants) from the $2^{nd}$ year middle school textbooks. The team selected themes in science writing that can cultivate multiple facets of creativity in students: flexibility, originality and elaboration. The format of the science writing was diverse. The program was conducted through worksheets, and there was separate section within the worksheet for teacher to give feedback to students. The science writing program with teacher's feedback improved students' scientific creativity(p<.01). It seems like teacher's feedback is critical in checking students' concept and boosting students' creativity. The program is statistically effective in improving students' flexibility(p<.01), however it is not the case for improving on their originality and ability to elaborate(p>.05). We assumed that the relatively extensive portion of the writing was not suitable to improve students' ability to elaborate their ideas further as well as fostering originality. In order to improve the students' creativity and ability to elaborate, there is a need to adjust the amount of science writing, content, time.

To extend the potential benefits of error, the current study examined factors that affect students' error perception in the classroom. An experimental design was used to measure relations of classroom goal structure, feedback, and social relationships on students' perception of error. A total of 316 fourth-, fifth-, and sixth-grade elementary students participated as part of their regular class curriculum. Self-reported questionnaires were administered to measure students' perception of errors and relationships with teacher and peers, and then students were manipulated by classroom goal structure and feedback. Multiple regression analysis results suggested that students' perception of learning from error was affected mostly by relationships with peers, followed by relationships with teacher and the type of feedback. Students' perception of risk taking for error was also affected by relationships with peers and teacher, followed by the classroom goal structure. However, classroom goal structure and feedback did not affect their perception of thinking about error to improve their learning as well as error strain. These results imply how the classroom climate should be structured to improve perception of errors to improve student's learning.

Based on an ecological model of teacher agency, the purpose of this study was to examine the relevance of HE (home economics) subjects and CSE (comprehensive sexuality education) for HE teachers, and their implementation in HE classes. To achieve this, a survey was conducted with HE teachers nationwide for which 243 responses were collected, and interviews were conducted with five HE teachers who were actively practicing CSE. The results of the survey and interview were as follows. First, HE teachers strongly recognized the relevance of HE subjects and the topic of CSE with an average score of 4.63 (out of 5 points), and practiced CSE at an average of 72.23% (97.12%~43.21%) in their class. Second, based on the ecological approach model of teacher agency, the factors facilitating the CSE practice of HE teachers included: childbirth and parenting experienced as parents, experiences of students encountering sexual problems in school, the philosophy and content of HE subjects, positive feedback from students and support from fellow teachers, and intention to help students in their lives. Conversely, HE teachers cited a lack of sexual education experience as learners, complaints from parents, weakness of HE teacher networks, lack of specific statements in curriculum and textbooks, insufficient class content and teacher training, and lack of absolute class time. This study is significant in revealing that CSE is highly relevant to the contents of HE subjects and is already being practiced in HE classes.

Kinect sensors have the ability to recognize the behavior and voice of the user. Due to its low-cost and high accessibility, Kinect sensors have been used in various fields, including healthcare, education and so on. In this paper, we propose to use Kinect in piano education. Specifically, the proposed method first recognizes the coordinate values of user's posture, compares them with coordinate values of teacher's posture and provide real-time feedbacks to the user. This enables user to keep the correct posture even when he is learning piano without a teacher. However, since the piano education is a long process, it is difficult to achieve the correct posture as a teacher immediately. Thus, we propose a user-oriented method to measure the error tolerance rate. The proposed method is the first feedback based piano education system that uses Kinect sensors.

This study is a report about the two summer camps of 2009 and 2010, which were held by some gifted classes of Liberal Arts areas in Chungnam Province. The students' self- directed methods, making an own project topic and an outline plan for that by students themselves before the camp, raised up the students' satisfaction of the camp effectively. Staying with their peer students and teachers for 3 days gave the gifted students a chance for relationship, self-confidence, and self-sufficiency. These joint summer camps provided the students with cognitive development, motivations and a chance to meet other gifted students. Teachers' preparation for the camp, their concrete feedback to each student's project, and students' time spending on one's own camp project were correlated with the students' satisfaction of the camp program. Experience of teacher training in gifted education made significant differences in understanding gifted students and expectations of students' social and emotional development throughout and after the camp.

The Web programming techniques like CGI and server-sided script languages such as ASP, PHP and JSP have been used for developing on-line Web-based learning systems on SQL. But, the systems developed by using those techniques are dependent on the platforms on which the target DBMS's are located. Therefore, they can be hardly reused and maintained. In addition, it is not easy for them to provide a learner with the feedback information on processing his/her query and to give a teacher an opportunity of monitoring and guiding learner's learning process. In this paper, we propose an SQL learning system on the Web by using Java Applet and JDBC, which is independent on the target DBMS's. Moreover, it gives feedback information on learner's queries so that a teacher can monitor the learning process and teach them efficiently.

Current performance evaluation of the natural science section mainly focuses on teacher evaluation, which causes slow feedback on the evaluation result and little evaluation on colleagues due to limits of time and space. In addition, report performance evaluation, which is a main target of the evaluation in the natural science section, is conducted mostly based on records of experiments and observation without any systematic forms. Such performance evaluation cannot meet expectation on the evaluation for a self-adjustment through instant feedback on the evaluation result and improvement of motivation through sharing common performance standard. Therefore, the study here completes an experiment/research report through information sharing and discussion among colleague learners based on the web and uses it for colleague or teacher evaluation. In addition, it is intended to recognize needs of learners and develop a performance evaluation system that can provide learners with appropriate feedback through the result.
