교수-학습 발화는 발화 턴 간에 규칙화된 인과관계가 강하고 자연 발화에서의 출현율이 낮다. 일반적으로 어휘부, 표현 제시부, 대화부로 구성되며 커리큘럼과 화제에 따라 구축된 언어자원이 필요하다. 기존의 말뭉치는 이러한 교수-학습 발화의 특징을 반영하지 않았기 때문에 한국어 교육용 튜터링 챗봇을 개발하는데에 활용도가 떨어진다. 이에 따라 이 논문에서는 자연스러운 언어 사용 수집, 도구 기반의 수집, 주제별 수집 및 분류, 점진적 구축 절차의 원칙에 따라 교수-학습의 실제 상황을 반영하는 준구어 말뭉치를 구축한다. 교실에서 발생하는 언어학습 상황을 시나리오로 구성하여 대화 흐름을 제어하고 채팅용 메신저와 유사한 형태의 도구를 통해 말뭉치를 구축한다. 이 연구는 한국어 튜터링 챗봇을 개발하기 위해 말뭉치 구축용 챗봇과 한국어 학습자, 한국어 교수자가 시나리오를 기반으로 발화문을 생성한 준구어 말뭉치를 최초로 구축한다는 데에 의의가 있다.

In his paper "Structural Equations Approach to Token Causation: The Active Route Account Revisited" Professor Sungsu Kim defends the active route account. The active route account is the theory of causation which overcomes counterexamples to the counterfactual theories of causation, while maintaining the counterfactual theorist's essential intuition that an effect depends counterfactually on a cause. Unfortunately, there are counterexamples to the active route account itself. Professor Sungsu Kim attempts to defend the active route account by rebutting those counterexamples. In this paper, I argue that his defense of the active route account is not successful.

This study analyzed problem presenting and solving activities in elementary school mathematics class to enhance insights of teachers in class for providing real meaning of learning. Following research problems were selected to provide basic information for improving to sound student oriented lesson rather than teacher oriented lessons. Protocols were made based on video information of 5th grade elementary school 'Na' level figure and measurement area 3. Congruence of figures, 4. Symmetry of figures, and 6. Areas and weight. Protocols were analyzed with numbering, comment, coding and categorizing processes. This study is an qualitative exploratory research held toward three teachers of 5th grade for problem solving activities analysis in problem presenting method, opportunity to providing method to solve problems and teachers' behavior in problem solving activities. Following conclusions were obtained through this study. First, problem presenting method, opportunity providing method to solve problems and teachers' behavior in problem solving activities were categorized in various types. Second, Effective problem presenting methods for understanding in mathematics problem solving activities are making problem solving method questions or explaining contents of problems. Then the students clearly recognize problems to solve and they can conduct searches and exploratory to solve problems. At this point, the students understood fully what their assignments were and were also able to search for methods to solve the problem. Third, actual opportunity providing method for problem solving is to provide opportunity to present activities results. Then students can experience expressing what they have explored and understood during problem solving activities as well as communications with others. At this point, the students independently completed their assignments, expressed their findings and understandings in the process, and communicated with others. Fourth, in order to direct the teachers' changes in behaviors towards a positive direction, the teacher must be able to firmly establish himself or herself as a teaching figure in order to promote students' independent actions.

The purpose of this study is to probe secondary science teachers' perception on scientific models and modeling. A total of 50 experienced science teachers were surveyed with 10 open-ended questions about several aspects of models and modeling: definition, examples, purpose, multiplicity, changeability, design/construction, evaluation and beliefs in the use of models and modeling as a teaching tool. The analysis of the data shows the following results: 1) understanding of models and modeling held by a majority of experienced secondary science teachers was far from that of experts as they concentrated on a model's superficial, representative, and visual functions, 2) when it comes to their view toward the use of a model, a model does not remain in the stage of 'doing science' but in the stage of being a subsidiary teaching tool for the teacher's explaining and the students' understanding of scientific concepts, 3) the subjects they majored in made meaningful differences in their contextual understanding of models and modeling, 4) though most of the teachers acknowledged the importance of teaching about models and modeling, even a lot of them showed a negative position toward the opinion that they are willing to apply modeling to their classes. Implications of the results were discussed in terms of intervention in order to enhance secondary science teachers' understanding and pedagogical content knowledge of models and modeling.

The purpose of this study is to analyze how a peer mentoring method affects students' problem solving abilities and class satisfaction in the context of high school quadratic curves and provide implications for teaching and learning mathematics. For this study, seventy six 11th graders in the natural sciences track participated in the peer mentoring method. After finishing the teaching method, Problem Solving Abilities Questionnaire was collected for analysis of pre-test/post-test experiments and Class Satisfaction Questionnaire was also gathered. The results show that the mentoring method positively impacts on participants' problem solving abilities and class satisfaction because its comfortable learning environments, individualized learning contents, and unconstrained learning processes motivate them through ways to improve their communication. According to the results, it is to address practical implications applied in teaching quadratic curves in high school with the value and importance of mentoring methods.

This study investigated how the unique educational contexts in the Republic of Korea (RK) impacted two science teachers' teaching practices in a public middle school and what the science teaching experience means to them. In particular, we explored how the middle school science teachers decide pedagogical approaches to use in their teaching based on classroom climate, students' attitude toward learning science, school curriculum and classroom culture. Using a phenomenological research approach, we analyzed classroom observation data and interview data to interpret the teachers' science teaching experience. Results of the study showed that the teachers' practice was dominantly affected by two external factors. First, the teachers' teaching practice was affected by the amount of science content knowledge they need to cover within a given class time. Second, the teachers' teaching practice was affected by students' attitudes toward science learning and their science preparedness in private tutoring centers. Implications of the study results are discussed in the paper.
