This study is design and implementation of diagnosis module using item response theory to assess level of student's knowledge in web-based instruction systems. Item response theory uses responses to items on a test or survey questionnaire to simultaneously locate both the items on the latent trait defined by the set of items while simultaneously scaling each item on the very same dimension. Existing method of measurement in web-based instruction system provided dichromatic learning after to be assess just with the total scores of exam. This measurement has an error that do not consider the level of student's knowledge. Moreover, this method can't perform an exact diagnosis of student knowledge and make student modeling to construct intelligent tutoring system. In this study, we present that design and implement a diagnosis module using item response theory to assess level of student's knowledge in web-based instruction systems

Considerable interest has been directed toward utilizing virtual environment-based simulations for teacher education which provide authentic experience of classroom environment and repetitive training. Emotional Interaction should be considered for more advanced simulation learning performance. Since emotion is important factors in creative thinking, inspiration, concentration, and learning motivation, identifying learners' emotional interactions and applying these results to teaching simulation is essential activities. In this context, this study aims to identify the objective data for the empathetic response through the movement of the learner's EEG (Electroencephalogram) and eye-tracking, and to provide clues for designing emotional teaching simulation. The results of this study indicated that intended empathetic response was provided and in terms of valence (positive and negative) states and situational interest played an important role in determining areas of interest. The results of this study are expected to provide guidelines for the design of emotional interactions in simulations for teacher education as follow; (a) the development of avatars capable of expressing sophisticated emotions and (b) the development of scenarios suitable for situations that cause emotional reactions.

The classification is an important activity that is directly related to concept formation. Thus it will need to be made meaningful learning to classification through learner-centered teaching. But we doubts weather teaching and learning to the classification are reflected in the constructivist philosophy of 'learner-centered' well or not. The purpose of this study was to analyze critically the content of elementary textbooks and guidebook for teachers relating to the classification of angles and triangles in terms of constructivism. As a result, there is a problem in the classification of angles that are not provided a reasonable chance to set criteria by agreement of the communities. There is a problem in the classification of triangles that has the characteristics of radical development in terms of diversity. In addition, response of students was predicted like anyone who already acquired knowledge. And it has the shortcomings that the opportunity to have a choice and a discussion to hierarchical and partition classification are not provided. The followings are proposed based on such features; faithful reflection of 'Learner-centered' principle, careful prediction of student response, teaching that focus on process than results.

Meaningful learning occurs through an active process of engaging with the content in a lively interaction between teacher and student. In this study, we explored teachers' learning, challenges, and changes as they learned and practiced responsive teaching (RT), a practice that supports students to put their ideas at the center of their lessons. As a result, we found that teachers initially embraced RT from different perspectives and struggled to implement it in ways they understood. We then explored RT more deeply by focusing on the case of a teacher who was teaching science herself, and found that her experience was both rewarding and confusing. However, by the end of the learning process, the teachers were able to define RT in their own ways, which strengthened their commitment to implementing RT in elementary science education. Based on this teacher learning process, it was suggested that teachers should be viewed as curriculum experts, that they should learn and explore collaboratively through a community of teachers, and that they should be researchers who continue to explore various practices in the field.

This paper proposes an adaptive tutoring system that provides learning materials dynamically according to the learners' teaming character and ability. Our system, in which a learning phase and a test phase are linked together, supports the personalized instruction-learning by providing the teaming materials by level in the learning phase according to the teaming ability estimated in the test phase. We design and implement a tutoring system consisted of an evaluation component and a learning component. An evaluation component uses a computerized adaptive test(CAT) based on item response theory to evaluate learners' ability while a learning component employs fuzzy level set theory so that teaming contents are provided to learners according to learners' level.

The purpose of this research is to develop an effective teaching-learning model and suggest efficient methods for improving the learning abilities in mathematics of the students of engineering college. For this purpose, we examined their learning styles and learning attitudes toward Mathematics, which are important factors in teaching-learning process, and analyzed the relation between them. As a result, we found that participants had a disposition of being dependent and highly participating, so we made an effort to develop a teaching-learning model which can make the students active and highly involved in. After applying the developed teaching-learning model to Engineering Mathematics class for one semester, we conducted survey of the participants' responses. In conclusion, we found that this model is very helpful for Engineering students to utilize a self-directed learning by diagnosing and adjusting their learning process in Meta-cognitive way. Also, it is confirmed that this model has a considerable influence in which students can actively participate in class and have positive attitude to Mathematics learning.

This study aimed at designing an effective earth science instruction which would help to improve students' scientific creativity using the questioning strategies. The developed questioning strategies were applied to 153 students of $10^{th}{\sim}11^{th}$ grades from March, 2004 to February, 2006. The Reaction Evaluation of Educational Program was used for students' reponses on these questioning strategies. And the Creativity Test developed by the Korea Institute for Aptitude Test was used for the changes of students' scientific creativity. The students responded that these questioning strategies improved students' scientific creativity, and those did not promoted interaction between the teacher and the students. After implementing these questioning strategies, students' analogical ability of language was evaluated the largest score among the 6 categories of scientific creativity. The survey about students' scientific creativity showed that there are meaningful differences between before and after implementing these questioning strategies : analogical ability of figure, analogical ability of language, reading comprehension ability.

지난 코로나 상황 동안 비대면 수업을 진행했고, 학생들은 빠르게 적응했다. 온라인 수업은 학습자가 이해될 때까지 반복 학습이 가능하고, 시간과 공간의 제약 없이 자기 주도적으로 학습할 수 있다는 장점이 있지만, 온라인상이라는 특징 때문에 교수자와 학습자 간 상호작용이 부족하다는 한계점이 존재한다. 하지만 이점은 차후에 비대면 수업의 지속적인 활용 및 확대를 제한하는 요인이 될 수 있다. 본 논문에서는 상호작용을 높일 수 있는 웹 기반 에듀테크 시스템을 제안한다. 온라인 수업의 강의 영상을 세부적인 내용을 나누는 Section을 통해 다른 학생들이 질문했던 Q&A 데이터를 모아서 생성된 Section-FAQ를 열람할 수 있고, 그 Q&A에 반응해서 상호작용이 가능하다. 또한 교수자에게 Q&A를 보낼 때 영상의 Section 정보와 강의시간 정보를 같이 전송하여 강의 영상을 확인하지 않고, 빠른 답변이 가능하도록 설계했다. 본 논문에서 제안하는 온라인 수업의 상호작용 향상을 위한 웹 기반 에듀테크 시스템을 통해 온라인상에서 교수자의 역할을 대신해주고 비대면 수업의 단점을 해소해주면서, 교수자과 학습자 간의 상호작용을 높여 수업의 이해도를 높이고 학습자들의 학업성취를 높일 수 있을 것이다.

This case study contributes to the efforts on identifying the essential features of responsive teaching practice where students' mathematical thinking is central in instructional interactions. We firstly conceptualize responsive teaching as a type of teachers' instructional decisions based on noticing literature, and agree on the claim which teachers' responsive decisions should be accounted in classroom interactional contexts where teacher, students and content are actively interacting with each other. Building on this responsive teaching model, we analyze classroom observation data of a 7th grade teacher who implemented a lesson package specifically designed to respond to students' mathematical thinking, called Formative Assessment Lessons. Our findings suggest the characteristics of responsive teaching practice and identify the relationship between noticing and responsive teaching as: (a) noticing on students' current status of mathematical thinking by eliciting and anticipating, (b) noticing on students' potential conceptual development with follow-up questions, and (c) noticing for all students' conceptual development by orchestrating productive discussions. This study sheds light on the actual teachable moments in the practice of mathematics teachers and explains what, when and how to support teachers to improve their classroom practice focusing on supporting all students' mathematical conceptual development.
