This study investigated the aspects of how three preservice elementary school teachers conducted the data-text transforming discourses in their science simulation teaching and how their epistemological conversations worked for learners' construction of scientific knowledge. Three preservice teachers, who had presented simulation teaching on the seasonal change of constellations, participated in the study. The results revealed that one preservice teacher, who had implemented the transforming discourses of data-to-evidence and model-to-explanation, appeared to facilitate learners' knowledge construction. The other two preservice teachers had difficulty helping learners construct science knowledge due to their lack of transforming discourses. What we should consider for improving preservice elementary school teachers' teaching competencies was discussed based on a detailed comparison of three cases of preservice teachers' data-text transforming.

This study explores the impact of a flipped classroom, in terms of self-efficacy, for elementary pre-service teachers in US teacher education programs. This research project explores how ESL microteaching activity in the flipped classroom shapes teacher-candidates' self-efficacy regarding teaching culturally and linguistically diverse (CLD) students. By analyzing ESL microteaching videos, pre-service teachers' reflection papers, and individual interviews with the course instructors, the study results show how pre-service teachers enhance their self-efficacy in teaching CLD English language learners in mainstream content subject classrooms. Moreover, the researchers provide suggestions on how teacher educators can utilize the flipped classroom to create an authentic and meaningful learning experience, such as using ESL microteaching for pre-service teachers to shape their self-efficacy in order to be well-prepared for CLD English language learners. The implication is that Korean pre-service teachers should be prepared to teach CLD students in their mainstream classrooms.

In contrast with the earlier remote education that simply recorded off-line classes, modern remote education emphasizes on offering additional functions that could maximize learning efficiency. Usage of such multimedia information as the texts, graphics, sounds, animations is considered fundamental element in offering the additional functions. This paper designs and implements an encoder/decoder that could accommodate the multimedia information with emphasis on demonstrating execution files. Instructors can demonstrate my type of execution files or application data files, and the remote learners can freely try running the corresponding execution files by themselves. Consequently, a high-level of learning efficiency can be achieved by the proposed encoder/decoder.

This paper discusses the effect that classroom demonstrations have on students' conceptual understanding in concepts in introductory physics. We used the same conceptual survey to probe the students' understanding on certain concepts before and after taking the course. We introduce Hake's , which is used to evaluate the effect of various kind of teaching methods, suggested by physics education research groups, on conceptual understanding of students who took the class. The effect of physics class using demonstration turned to be better than the traditional lecture, higher for students who graduated from science schools with higher prior knowledge and demonstration experience. Authors suggest to use to probe concepts which need more attention.

In order to nurture talents who will lead the digital convergence era of the 4th industrial revolution that creates new knowledge and industries, research is being conducted on teaching methods that can improve the understanding of non-majors' SW concept, computational thinking ability, and convergence with majors is becoming Non-majors face difficulties in understanding and understanding the SW development environment, relevance to their major, and ability to converge. We used software education that is relatively easy to access for non-majors, and applied a demonstration-oriented model (DMM) that can be applied to beginners in SW education to understand the components and logical flow of ideas related to applications and majors used in real life. A convergence SW Learning method that combines repetitive implementation through instructor's demonstration and learner's modeling and learning motivational factors was proposed. In the experiment applying the teaching and learning method proposed in this paper, meaningful results were shown in terms of learning motivation and academic achievement in SW education.

In this study, we applied a web-based education system to the teaching-demonstrations of the pre-service teachers and identified the usefulness of the system as a method supporting constructive education for pre-service teachers. The pre-service teachers performed the web-based activities for the teaching-demonstrations, and we interviewed them after the teaching-demonstrations. On the basis of the results, we found three situations showing the usefulness of the web-based education system. First, the pre-service teachers examined the materials on the constructive teaching-learning theories and constructed the related theoretical knowledge. At this point the web-based discussion board supported the environment where they thought deeply and investigated the theories carefully. Second, they experienced interaction with others and the academic adviser in the processes of preparing the teaching-demonstrations. This interaction was supported by web-based discussion board, and they were able to form the practical knowledge related to the planning and building constructive teaching. Third, they reflected on their own teaching after the teaching-demonstrations. At this point, the web-based discussion board was able to facilitate the interaction for the reflective thinking processes. In this study, we identified that the web-based education system could provide an effective environment where the pre-service teachers could learn constructive teaching-learning methods.

In the SW education of non-majors who encounter liberal arts education experience difficulties in the SW development environment and understanding they encounter for the first time, relevance to their major, and convergence thinking ability. In order to compensate for the difficulties of non-major learners in liberal arts education, a relatively easily accessible software was used to utilize a demonstration-oriented model that can be applied to beginners in SW education. In order to understand the logical flow of applications and problem solving used in real life, we proposed a convergence SW teaching method that combines repeated implementation through demonstration by the instructor and imitation of the learner, and learning indicators to increase the learning satisfaction and achievement of the learner. In the experiment applying the teaching and learning method proposed in this paper, meaningful results were shown when evaluating the learning effect, academic achievement, learning satisfaction, and teaching and learning method aspects of SW education.

Developing pedagogical content knowledge (PCK) has been emphasized as one of the requirements for science teacher's professionalism, and it should be done from systematic teacher training courses. In this study, we investigated the components considered in planning instruction and the difficulties encountered in implementing it in PCK held by secondary pre-service teachers. Twenty-seven juniors at a college of education in Seoul were asked to perform teaching demonstrations using scientific instruction models. They were also requested to write reflective journals and interview. Analyses of the results revealed that teaching strategies and learners' cognitive affective aspects were considered by most secondary pre-service teachers, whereas curriculum and assessment were regarded by few of them. For examples, choosing instruction models and organizing instructions were concerned in teaching strategies. They also considered learners' cognitive affective aspects for selecting experiments as main activities. Only few considered learners' prior-knowledge. Most difficulties encountered in planning instruction and implementing it appeared in teaching strategies. Educational implications of these findings are discussed.

The purpose of this study was to investigate the enhancing creative competency and changes in academic challenge for the pre-service teachers. For this purpose, 94 pre-service teachers participated in project learning through the preparation of the convergence instruction and the class demonstration during one semester. The pre and post questionnaire survey was conducted the measurement of creative leader competence and K-NSSE for academic challenge. Analysis of data was performed using the IBM SPSS 18.0 program for the corresponding sample t test. The creative competency included 'higher mental thinking', 'problem solving', 'curiosity', 'sensitivity' 'task commitment', 'the pursuit of social value', and 'co-operations and considerations'. This results was significant(p< .05). Academic challenge, high-order learning domain and learning strategies domain were significant(p< .05). Based on this, in order to generalize the convergence education and convergence lesson, it is necessary to design various convergence lessons and practice study to make a plan and practice it. In addition, the implications for the necessity of correcting and supplementing the effects after repeated convergence lessons were discussed.

This study aimed at finding points of improvement in teaching expertise by analyzing the question patterns that appeared during teaching demonstrations which applied science teaching models prepared by a pre-service biology teacher. The question analysis frame for analyzing question types were categorized largely into the question types of Category 1 (questions in cognitive domain, questions with research function, questions in affective domain), Category 2 (repeated questions, questions for narrowing the range, practice questions), and Category 3 (questions on student activity progress, memory questions, and thinking questions). The results of analyzing question patterns from five different science teaching models revealed a high frequency of questions in the fields of cognition and memory. For the circular learning model, questions from the cognitive field appeared the most often, while, student activity progressive questions in particular were used mostly in the 'preliminary concept introduction stage' of the circular learning model and the 'secondary exploratory stage', in which experiments were conducted, and displayed the characteristics of these stages. The discovery learning model combined the courses of observation, measurement, classification and generalization, but, during teaching demonstrations, memory questions turned up the most, while the portion of inquisitive function questions was low. There were many questions from the inquisitive learning model, and, compared to other learning models, many exploratory function questions turned up during the 'experiment planning stage' and 'experiment stage'. Definitional questions and thought questions for the STS learning model turned up more than other learning models. During the change of concept learning model, the five concepts of students were stimulated and the modification of scientific concepts was very much aided by using many memory questions.
