The purpose of this study is to analyze verbal interaction between teachers and students in order to collect qualitative data on the characteristics of the interaction to enhance teaching efficacy. Total of 12 classes of eight science teachers were observed and were interviewed. The classes were video taped and all the verbal interactions were transcribed. The transcribed content and interviews were further analyzed to draw any conclusions on the verbal interaction between teachers and students. Analysis criteria for the data on the class and interview were developed based on the literature review and applied to analyze the collected content. The analyzed data showed that verbal interactions composed of confirmation questions for memorization, students' short responses and teacher's immediate feedbacks. The results of the study also suggested that there needs to be further studies on the interactional techniques for teacher in utilizing the class materials and activities. The teachers should acknowledge the importance of the questions and feedbacks of teachers for students to stimulate their sound learning through literatures.

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.

Internet, a world wide network of computers, is considered as a sea of information because it allows people to share information beyond the barriors of time and space. However, in spite of the unmeasurable potential applications of the internet, its use in the field of biology education has been extremely limited mainly due to the scarcity of good biology-related sites. In order to provide useful guidelines for constructing user-friendly study sites, which can help high school students with different intellectual levels to study biology, comparative studies were performed on selected educational sites. Initially, hundreds of related sites were examined, and, subsequently, four distinct sites were selected not only because they are well organized, but also because each is unique in its contents. Also, a survey was carried out against the users of each site. The survey results indicated that the high school students regard the web-based biology study tools as effective teaching methods although there might be some bias in criteria for selecting target sites. In addition to the detailed biology topics and the related biology informations, multimedia data including pictures, animations and movies are found to be one of the important ingredients for desirable biology study sites. Thus, the inclusion of multimedia components should also be considered when developing a systematic biology study site. Overall, the role of the cyber space is expected to become more and more important. Since the development of the user-satisfied and self-guided sites require interdisciplinary collaborational efforts which should be made to promote extensive communication among teachers, education professionals, and computer engineers. Furthermore, the introduction of good biology study sites to the students by their teachers is also important factor for the successful web-based education.

The purpose of this study was to explore the effects of science classes on positive science experiences and science learner identity, using smart devices in a future school: C middle school. We conducted a paired t test at the beginning and end of the first school year with first-grade students at the future school to investigate positive experiences with science (Shin et al., 2017). Additionally, first and second-grade students in future schools using smart devices wrote and drew their own depictions in science classes to explore science learner identity, based on a modified analytical framework (Luehmann, 2009). The results show that significant effects on science-related career aspirations, self-concepts, and academic emotions were produced by science classes using smart devices. Science classes using smart devices helped students improve their level of agency and activity, solve problems with immediate and sufficient feedback, and experience meaningful perceptions of the nature of science. On the other hand, if students were immature in terms of their use of smart devices, they felt pressured to participate in the classes. The results of this study can be used as a foundation for designing various classroom contexts for the use of smart devices.

Though it has been known that self-efficacy is a predictor to the successful L2 learning, the majority of studies on self-efficacy cases were targeted at secondary school students. This paper aims to explore the effects of the intermediate college students' essay writing experiences on their English self-efficiency. For this purpose, pre and post course surveys were conducted on a hundred or so freshmen who took intermediate college English classes which focused on improving English reading and writing skills. Interviews with teachers were also conducted in order to find out whether the differences of their teaching styles had any meaningful impact on their students' self-efficacy. Paired t-test was run on the responses of the post-questionnaire to identify any differences in the self-efficacies of the students before and after taking the classes, and the one-way ANOVA was conducted to find out whether the different instruction types had any significant impact on the differences. The results of the both analyses confirmed the differences of self-efficacies by the two predictors at a statistically significant level. Based on the findings of this paper, various types of writing assignments and efficient procedures of teachers' feedback need to be developed further in order to design and run an effective college English course which can contribute to enhancing self-efficacy of students.

This study compares and analyzes the characteristics and effects of various educational contextual variables according to students' achievement level and gender groups based on the results of PISA 2015 science domain. PISA 2015 included additional variables about teaching-learning and affective characteristics in the field of science, because science was the main domain of PISA 2015. The results of the mediation analysis using a multiple group structural equation model showed that the environment and strategy for the teaching and learning had a positive effect on the affective characteristics, and also positively affected science achievement through the mediator of the affective characteristics. Particularly, the environment and strategy for the teaching and learning was the most effective in improving the affective characteristics for the low achievement group. It was found that the difference of the mediated effect between achievement level groups was statistically significant, but that between male and female students was not. Therefore, the appropriate the environment and strategy for the teaching and learning will need to be emphasized consistently to improve students' cognitive and affective achievement. The implications and suggestions of these results were discussed.

This study aimed to develop a music teaching-learning program for secondary students with intellectual disabilities in special education settings based on music therapy approach. Designed lesson plans included three learning domains based on the guidelines from 2008 amendments to the special education music curriculum: Perception, expression, and appreciation. Within the domains, instruction topics and its corresponding contents were re-structured as considered more appropriate and effective for implementing music classes for this population. With consideration of therapeutic goals as well as educational goals, student activities and teacher activities were designed and the activities were presented at three levels depending on students' functional levels. Integrating these instructional components into an actual plan, this study presented yearly (for 20 hours of classes) and monthly lesson plans. The developed lesson plans were reviewed and verified by related professionals including special class teachers and music therapists. As systematic and well-organized lesson plans, the results from this study would provide basic music education resources for students with intellectual disabilities in special education settings. It would also enable the discussion on the music therapy-based teaching-learning program as new methodological and strategic ideas applicable to future special education.

Using TIMSS survey data, we analyzed whether there were any significant changes in the learning environment of middle school science classes over the last 10 years. Our study selected questions from teachers and school principals' questionnaires and divided them by category: science class, teacher professional development, and school environment. The science class components were subdivided into three categories: science learning activities, evaluation, and homework. Within teacher professional development, the sub-categories included teacher training, collaboration to improve teaching, and teacher evaluation. School environment subdivided into two aspects, these being school characteristics and school system. Our research confirmed that there has been a positive change overall in learning environments. However, most classes are teacher-conducted and also teacher-oriented; the proportion of science investigation activities has declined compared against the prior ten years. Our study show that students do not engage in a range of inquiry-related activities. The questions on tests and examinations involve mostly knowledge application and understanding, although recent methods of evaluation show improvement. As for the science teachers, they participate in many professional development programs but focus on science content, science curriculum, and pedagogy. In addition, teachers do not have many opportunities to participate in the training to integrate information technology into science, science assessment, or improving students' critical thinking or inquiry skills. The teachers are satisfied with their profession, and the shortage of science resources does not seem to affect instruction.
