This study investigated the analysis of examples that gifted students' realizing the learning objectives through teaching method of the teacher's questions and advice. 6 gifted students were selected to be examined with 'magic square' in class. The teacher emphasized the learning objectives without directly proposing. Whereas, the teacher proposed the learning objectives by questioning and giving advice to students. After the class, the 6 gifted students were surveyed to answer about realizing the learning objectives of mathematics (about contents, process, and attitude in mathematics learning objectives). Mathematical gifted students thought about the process that consists of deductive thinking, analogic thinking, extensive thinking, creative thinking, and critical thinking. But, they underestimated the deductive thinking. So the teacher should develop the questions and advice to teach the mathematical gifted students according to the level of them. The high level of mathematical gifted students were able to realize the value and the importance of the mathematical attitude, while the low level of mathematical gifted students were able to realize them little. For this reason, the teacher should apprehend the level of the students, and propose materials and contents of the learning. The teacher should also make the gifted students realize value, will, and personality of mathematics by questions and advice. Lastly, like it is needed in general classes, there should be a constant researches and improvements about questions of the teacher that are appropriate to each student's learning abilities and cognition ability.

The purpose of this study is to analyze the aspects of teacher librarians' book recommendation services for individual readers. For this purpose, data were collected through in-depth interviews with the teacher librarians of elementary school. Through the analysis of the collected data, the process of the teacher librarians' book recommendation, the main characteristics of the book recommendation, and the factors considering in the book recommendation, as well as information on major issues that arise in the book recommendation activity were derived and presented. Specifically, it was confirmed that the teacher librarians's book recommendation process was implemented in the following stages: questioning and interviewing, book recommendation, and follow-up. And, it was investigated that the factors considered when recommending books were students' interest, reading history, book fun, reading level, book level, teacher, class, and curriculum. In addition, it was confirmed that differences occurred in the experiences and perceptions of teacher librarians in the process of considering these factors. These results can provide the implications for resolving the problems of the teacher librarians who perform book recommendation services.
In this paper, some factors such as the perspective of children, instructional materials(especially activities in textbooks for elementary school mathematics), and teacher's questioning styles are discussed as ones influenced on students' immersion in leaner-centered instruction. This discussion is based on the author's two implementations of the kind of two instructions. About the first theme, constructivists assert that even children who are in elementary school can have reflective abstracting ability. Teachers' asking questions with the belief differ from ones with traditional perspective of children, which is relevant the third factor. They value and respect learners' thinking outcomes, even though they are not sometimes wrong and have errors. Also, they have them opportunities to think different from others and to ask how they get their answers. To do these, they frequently ask open-ended questions, not closed. All of them is possible through the activities provided in textbooks. Some characteristics which can prompt such teacher's questions using activities in elementary mathematics textbooks are discussed.
This study used a Chatbot, a generative artificial intelligence (AI), to analyze the interaction between the Chatbot and students when exploring critical minerals from an epistemological aspect. The results, issues to be kept in mind in the teaching and learning process using AI were discussed in terms of the role of the teacher, the goals of education, and the characteristics of knowledge. For this study, we conducted a three-session science education program using a Chatbot for 19 high school students and analyzed the reports written by the students. As a result, in terms of form, the students' questions included search-type questions and non-search-type questions, and in terms of content, in addition to various questions asking about the characteristics of the target, there were also questions requiring a judgment by combining various data. In general, students had a questioning strategy that distinguished what they should aim for and what they should avoid. The Chatbot's answer had a certain form and consisted of three parts: an introduction, a body, and a conclusion. In particular, the conclusion included commentary or opinions with opinions on the content, and in this, value judgments and the nature of science were revealed. The interaction between the Chatbot and the student was clearly evident in the process in which the student organized questions in response to the Chatbot's answers. Depending on whether they were based on the answer, independent or derived questions appeared, and depending on the direction of comprehensiveness and specificity, superordinate, subordinate, or parallel questions appeared. Students also responded to the chatbot's answers with questions that included critical thinking skills. Based on these results, we discovered that there are inherent limitations between Chatbots and students, unlike general classes where teachers and students interact. In other words, there is 'limited interaction' and the teacher's role to complement this was discussed, and the goals of learning using AI and the characteristics of the knowledge they provide were also discussed.
In most classrooms, teachers talk more than students. Teachers have been thought to be knowledge-donors and students have been thought to be knowledge-acceptors, so teacher-talks were thought to be more important than student-talks. But student-talks are very important to the students: not only to the students who speak out their opinions or answer to the questions given to them, but also to the others who say nothing in the class. Many students in Korea are not so fond of speaking out something to all the class, so some teachers are using a strategy: to say something as if he for she) is a student in the classroom. What teachers talk are not the words of the teacher-talks. They are only talked by the teachers, but they function like student-talks. To study this type of talks are needed to help both teachers and students but there are not much research about this. So in this paper we a) name it Pseudo Student Talk (PST), b) define it as 'a kind of talks that are not talked by students of the class but its functions are very similar to the student-talks', c) classify PST in 'EBS 2005 science class for 7th grade' according to types of student talks (categorized by Lemke, 1990), and d) show the usage of each kind of PST.

In this study, we investigated the changes in beginning chemistry teachers' teaching practice without mentoring program and after the implementation of mentoring program. Participants in our study included two chemistry teachers who have less than one year of teaching experience and three mentor teachers. We collected data such as video recordings of teacher's classes, interview, and recordings of mentoring after each class. The results show there were slight changes in teaching contents, teaching procedure, and explanation method without mentoring. On the other hand, there were a lot of significant improvement in classroom environment, teaching contents and teaching procedure, teaching-learning techniques, questioning and feedback, and explanation method after mentoring has been implemented. However, there were no easy changes in the teaching style, understanding of students, and ways of interaction with students in connection with teaching purposes. Based on the results of this study, we explored the possibilities of instructional improvement through mentoring on beginning chemistry teacher's teaching practice. Therefore, we consider that more systematic and long-term mentoring is necessary to improve professionalism in teaching beginning teachers. In particular, we propose mentoring programs reflecting the individual needs of beginning teachers.
This paper presents cross-national perspectives on challenges in implementing current mathematics education reform ideals. This paper includes detailed qualitative descriptions of mathematics instruction from unevenly successful second-grade classrooms both in Koran and in the U. S with regared to reform recommendations. Despits dramatic differences in mathematics achivement between Korean and the U.S student. problems in both countries with regard to mathematics education are perceived to be very similar. The shared problems have a common origin in teacher-centered instruction. Educational leaders in both countries have persistently attempted to change the teacher-centered pedagogy to a student-centered approach. Many teachers report familiarity with and adherence to reform ideas, but their actual classroom teaching practices do not reflect the full implications of the reform ideals. Given the challenges in implementing reform, this study explored the breakdown that may occur between teachers adoption of reform objectives and their successful incorporation of reform ideals by comparing and contrasting two reform-oriented classrooms in both countries. This comparison and contrast provided a unique opportunity to reflect on possible subtle but crucial issues with regard to reform implementation. Thus, this study departed from past international comparisons in which the common objective has been to compare general social norma of typical mathematics classes across countries. This study was and exploratory, qualitative, comparative case study using grounded theory methodology based on constant comparative analysis for which the primary data sources were classroom video recordings and transcripts. The Korean portion of this study was conducted by the team of four researchers, including the author. The U.S portion of this study and a brief joint analysis were conducted by the author. This study compared and contrasted the classroom general social norms and sociomathematical norms of two Korean and two U.S second-grade teachers who aspired to implement reform. The two classrooms in each country were chosen because of their unequal success in activating the reform recommendation. Four mathematics lessons were videotaped from Korean classes, whereas fourteen lessons were videotaped from the U.S. classes. Intensive interviews were conducted with each teacher. The two classes within each country established similar participation patterns but very different sociomathematical norms. In both classes open-ended questioning, collaborative group work, and students own problem solving constituted the primary modes of classroom participation. However in one class mathematical significance was constituted as using standard algorithm with accuracy, whereas the other established a focus on providing reasonable and convincing arguments. Given these different mathematical foci, the students in the latter class had more opportunities to develop conceptual understanding than their counterparts. The similarities and differences to between the two teaching practices within each country clearly show that students learning opportunities do not arise social norms of a classroom community. Instead, they are closely related to its sociomathematical norms. Thus this study suggests that reform efforts highlight the importance of sociomathematical norms that established in the classroom microculture. This study also provides a more caution for the Korean reform movement than for its U.S. counterpart.
This study aims to investigate the characteristics of verbal interaction in science class demonstrations conducted by elementary school pre-service teachers. Specifically, the study intends to examine the use of elements of verbal interaction and the progression of these interactions. Additionally, the study intends to analyze the perception of pre-service teachers about effective questioning and feedback and to determine the correlation between the proportions of the types of questioning and feedback positively perceived by the pre-service teachers and of the types of questioning and feedback used during class demonstration. Toward this end, the study analyzed the science class demonstration videos and class evaluation sheets submitted by 38 fourth-year students at the S University of Education. The results are as follows. First, pre-service elementary school teachers generally use close-ended questions during science class demonstrations. Moreover, they predicted that students would primarily provide the correct responses and would not engage in extended interaction by providing immediate feedback for the responses of the majority of the students. Second, pre-service elementary school teachers perceived the utilization of close-ended questions and immediate feedback in science class demonstrations more favorably than they did that of open-ended questions and delayed feedback. The study observed a weak positive correlation between the positive perception of specific types of questions and feedback and the use of such types in class demonstration. The results demonstrated that pre-service elementary school pre-service teachers tend to engage in fragmented verbal interactions during science class demonstrations. They primarily use close-ended questions and immediate feedback. This tendency is seemingly related to their perception of questions and feedback. Therefore, education institutions for training pre-service teachers need to provide opportunities for reflecting on verbal interactions, which tend to involve close-ended questions and immediate feedback. Lastly, assessing the perception of pre-service teachers of questions and feedback is also necessary.

The purpose of this study is to examine differences between nursery teachers and kindergarten teachers in their perception on key elements of effective interactions and enhanced teaching competence. The subject of the study were 143 early childhood teachers in the Y region of Gyeonggi-do. The collected data was processed through frequency and percentage. For difference test, ${\chi}^2$ tests were conducted. The results of this study can be summarized as follows. First, both nursery teachers and kindergarten teachers perceived that listening and playing were the most important factors in effective interactions between young children and teachers. However, nursery teachers perceived the interaction through skin-ship and complimenting to be more important whereas kindergarten teachers perceived questioning and complimenting as necessary. For the teaching criteria, nursery teachers put more weights on playing while kindergarten teachers focus more on explaining and coorperating. In addition, about evaluation methods, nursery teachers perceived self-evaluation as important, whereas kindergarten teachers perceived observation notes as important. Second, about the elements to strengthen teaching competence, nursery teachers perceived that observation records should be utilized for understanding interest or desire. They also believe that development analysis and teaching methods should be improved through systematical teaching plan and evaluation and that enhancement of teaching material and education are necessary. In contrast, kindergarten teachers perceived that observation records should be utilized for teaching plan and development analysis and teaching methods should be improved through participating in the meetings related to career and education. They believe that providing a prize money through supervising evaluation is necessary.
This study conducted an analysis of types of reasoning shown in students' solving a problem and processes of students' reasoning according to type of problem by posing an open-ended problem where students' reasoning activity is expected to be vigorous and a multiple-choice problem with which students are familiar. And it examined teacher's role of promoting the reasoning in solving an open-ended problem. Students showed more various types of reasoning in solving an open-ended problem compared with multiple-choice problem, and showed a process of extending the reasoning as chains of reasoning are performed. Abduction, a type of students' probable reasoning, was active in the open-ended problem, accordingly teacher played a role of encouragement, prompt and guidance. Teachers posed a problem after varying it from previous problem type to open-ended problem in teaching and evaluation, and played a role of helping students' reasoning become more vigorous by proper questioning when students had difficulty reasoning.
