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 and compares Korean and U.S. elementary preservice teachers' analytic approaches of students' addition and subtraction computational strategies. Twenty-six Korean and twenty U.S. elementary preservice teachers participated in the study. Participants were asked to analyze mathematical approaches and errors from students' addition and subtraction operations. Preservice teachers' written documents were analyzed by applying open coding and inductive coding based on the grounded theory. As a result, the pattern of error analysis and interpretation of students' addition computations were similar for both Korean and U.S. preservice teachers whereas there were some differences in the analysis of students' subtraction computations. Both Korean and U.S. preservice teachers had difficulties identifying students' strategies and errors for a complicated and unconventional computational approach. Results also indicated that preservice teachers' noticing and interpretation of students' strategies and errors were influenced by their K-12 mathematics curriculum and teacher education program. This study suggests implications and future directions for teacher education, more contextualized teacher preparation programs and balanced connection to the K-12 curriculum.

The development of teacher's professionalism through teacher education is a key element in the improvement of school education. However, there has been criticism that the mathematics teacher education in Korea do not provide given enough opportunities for the classroom experience during preservice teacher education period. For development of inservice mathematics teachers and preservice teachers' teaching professionalism, this study develops a research community for mathematics classroom consisting of experts, inservice mathematics teachers, and preservice teachers. And the study explores the possibilities of the model as an educational space for inservice teachers and preservice teachers by participating in a series of courses such as task development and revision, and observation and analysis of classes. As results, inservice teachers and preservice teachers were able to enhance the practical experience and understanding necessary for the class, and they were also positively influenced in teacher efficacy and view of teaching on the model. Based on this, we suggest the possibility of the model as a teacher education system.

With the advancement of digital technology, a variety of digital materials are being utilized in education. For their appropriate use of digital resources, teachers need to be able to evaluate the quality of digital resource and determine the suitability for teaching. This study explored how preservice teachers evaluate TocToc-Math, an Artificial Intelligence (AI)-based math support system. Based on an evaluation framework developed through prior research, preservice teachers evaluated TocToc-Math with evidence-based criteria, including content quality, pedagogy, technology use, and mathematics curriculum alignment. The findings shows that preservice teachers positively evaluated TocToc-Math overall. The evaluation tendencies of preservice teachers were classified into three groups, and the specific characteristics of each factor differed depending on the group. Based on the research results, we suggest implications for improving preservice teachers' evaluation abilities regarding the use of digital technology and AI in mathematics education.

This research examines how experiences related to multicultural issues influence the understanding, perception, attitudes, and self-efficacy of early childhood preservice teachers toward multicultural education in Korea and the United States. 512 early childhood preservice teachers in Korea and the United States participated. Their multiculture-related experiences and their understanding, multiculture-related characteristics(perception, attitudes, and self-efficacy concerning multiculture) were measured using questionnaires. The key findings are as follows. First, more preservice teachers in the United States took multiculture-related courses, had experiences with children from multicultural families, traveled to other countries, and took courses with students from multicultural background than their counterparts in Korea. Second, there were no significant differences in understanding of multiculture according to their multiculture-related experiences between Korean and the United States preservice teachers. Third, there were no significant correlations between preservice teachers' multicultural experiences and perception and attitude toward the multicultural education in the United States. On the contrary, Korean preservice teachers who took classes with students from multicultural families showed better perception and attitude toward multicultural education. Regarding self-efficacy, there were no differences with varying multiculture-related experiences in the United States, whereas Korean preservice teachers who took multiculture-related courses exhibited higher degree of self-efficacy toward multicultural education.

This study aimed to analyze the characteristics of good science teachings regarded by preservice elementary school teachers. It also aimed to suggest a direction of peer teaching practice to help preservice teachers' professional development. Adjacency pairs were adopted to analyze the characteristics of good science teachings. The results showed that pre-service elementary teachers were accustomed to adjacency pairs. Almost of their discourse were organized by adjacency pairs. 'Question-Answer' and 'Request-Accept' were mainly used in science classes by pre-service elementary teachers. Based on the findings, the study suggested science teacher educators to provide chances to analyze exemplary science teachers' science class or chances to analyze their science teachings in terms of competence of science classroom discourse.

Teachers and students' knowledge of zero was investigated through data collected from 16 preservice secondary mathematics teachers and 20 gifted secondary school students. Results showed that these teachers and students had an inadequate knowledge about zero. They exhibited a reluctance to accept zero as an attribute for classification, confusion as to whether or not zero is a number, and stable patterns of computational error. Although leachers and researchers have long recognized the value of analyzing student errors for diagnosis and remediation, students have not been encouraged to take advantage of errors as learning opportunities in mathematics instruction. The article suggests using errors as springboards for inquiry in action, discusses its potential contributions to mathematics instruction by analyzing students and preservice teachers errors related to zero.

This study investigated whether there was a difference between general teaching efficacy and science teaching efficacy of preservice elementary teachers. And, the difference was also examined in the area of several variables of the preservice teachers, such as gender, the university majors, the high school majors, and grades. The results showed that a significant difference was not found between general teaching efficacy and science teaching efficacy. Teacher variables were found as the major factors to explain the difference. In case of male students who are majoring in science/math at university, and the students who majored in science/math at high school, science teaching efficacy was higher than general teaching efficacy. Whereas, in case of female students and nonscience majors at university and high school, science teaching efficacy was lower than their general teaching efficacy. Educational implications for preservice elementary teachers were discussed.

This study explored changes of preservice biology teachers' pedagogical knowledge and science teaching efficacy belief after the science pedagogy course. Preservice biology teachers who did not take any science pedagogy courses had an opportunity to engage in discussions of educational theories and group activities of instructional design utilizing science instructional models as a first step to develop practical knowledge. These preservice teachers represented a statistically significant increase in their scores on pedagogical knowledge including theory, student development, planning, and implementation, but no statistical difference in their scores measuring science teaching efficacy belief. In addition, the correlation results indicated that the science teaching efficacy belief is related to implementation even though the magnitude is relatively moderate.
