This study analyzes the tasks selected and implemented by pre-service mathematics teachers to support students' development of epistemic actions. Data was collected from 20 students who participated in a mathematics education curriculum theory course during one semester, and multiple data sources were used to gather information about the microteaching sessions. The study focused on the tasks selected and demonstrated during microteaching by pre-service teachers. The results suggest that providing students with a variety of learning opportunities that engage them in different combinations of abductive and deductive epistemic actions is important. The tasks selected by pre-service teachers primarily focused on understanding concepts, calculation, and reasoning. However, the use of engineering tools may present challenges as it requires students to engage in two epistemic actions simultaneously. The study's findings can inform the development of more effective approaches to mathematics education and can guide the development of teacher training programs.

This research has an objective of investigating the challenges that student teachers encounter during practicum, the difference between teachers' image based on sociodemographic variables, recognition and satisfaction for practicum, and the effect of teachers' image and practicum experience on the satisfaction for the practicum. The participants of this study included 500 student teachers who enrolled in the department of early childhood education in a 2 or 3-year college or a 4-year university and completed practicum in the Chungcheong area. The instruments for this study were Teacher's Image Scale, Practicum Experience Scale, Practicum Satisfaction Scale and a questionnaire for sociodemographic variables. The results were as follows: First, the highest level of teachers' image was obtained for student teachers enrolled in a 2-year college, completed practicum in large cities and finished practicum at an institution with a size of 3-6 classes. Also, the highest level of 'recognition for practicum' of student teachers was observed when they were instructed by a guidance teacher with a degree from a graduate school and with a first degree certification in public kindergarten. Second, the satisfaction for practicum of student teachers was mostly affected by' the atmosphere of the practice institutions', while personality affected the teachers' image.

Research and national standards, such as the Next Generation Science Standards (NGSS) in the United States, promote the development and implementation of K-12 interdisciplinary curricula integrating the disciplines of science, technology, engineering, mathematics, and computer science (STEM+CS). However, little research has explored how teachers provide epistemic support in interdisciplinary contexts or the factors that inform teachers' epistemic support in STEM+CS activities. The goal of this paper is to articulate how interdisciplinary instruction complicates epistemic knowledge and resources needed for teachers' instructional decision-making. Toward these ends, this paper builds upon existing models of teachers' instructional decision-making in individual STEM+CS disciplines to highlight specific challenges and opportunities of interdisciplinary approaches on classroom epistemic supports. First, we offer considerations as to how teachers can provide epistemic support for students to engage in disciplinary practices across mathematics, science, engineering, and computer science. We then support these considerations using examples from our studies in elementary classrooms using integrated STEM+CS curriculum materials. We focus on an elementary school context, as elementary teachers necessarily integrate disciplines as part of their teaching practice when enacting NGSS-aligned curricula. Further, we argue that as STEM+CS interdisciplinary curricula in the form of NGSS-aligned, project-based units become more prevalent in elementary settings, careful attention and support needs to be given to help teachers not only engage their students in disciplinary practices across STEM+CS disciplines, but also to understand why and how these disciplinary practices should be used. Implications include recommendations for the design of professional learning experiences and curriculum materials.

This paper explores how unequally successful mathematics practices were constructed in the two elementary mathematics classrooms. The interview data that pertain to the two teachers' personal reflections on the influences on their professional development were used as a source of inquiry to identify the underlying factors that might account for the differences and the similarities in implementing reform ideals in teaching mathematics. This affords not only exploration of the challenges of moving teaching practices toward student-centered approaches but also insight of the processes of developing mathematics teaching practices through teachers\`own career paths.

Although student-centered teaching practices have been advocated in mathematics education reform, implementing them at the classroom level remains challenging. This exploratory case study examined two unevenly successful student-centered approaches to see how teachers understand and characterize reform, and to articulate issues in implementing reform ideas. The comparison and contrast between the classrooms showed similar classroom social norms but dramatically different mathematical practices. This affords the possibility of exploring the challenges of reform for teachers and other personnel who are attempting to move teaching practices towards the student-centered ideals.

This study explores the impact of a STEM integration teacher professional development program focusing on teachers' perception of engineering and their attitudes toward integrating engineering into teaching. A total of sixty-eight teachers from ten schools participated in the program for five days. Data are collected from three main sources including (1) pre and post concept maps probing teachers' perceptions about the engineering discipline, (2) a pre and post survey measuring teachers' self-efficacy of teaching science/mathematics within the engineering context, and (3) engineering integrated science and (or) mathematics lesson plans and teaching reflections. This study utilizes both qualitative and quantitative research methods depending on the data we have collected. The results show that both science and math teachers thought that integrating engineering into teaching provided valuable outcomes, i.e., promoting students' learning about engineering and improving their interest in science or math through real-world problem solving exercises. Participants also felt more comfortable about integrating engineering in their teaching after the program. The results also imply that the teachers' understandings of engineering become more concrete after the program. This study also provides an overview of the challenges and advantages of teaching engineering in K-12 science and mathematics classrooms.

Conducted within the methodological framework of action research, this study examines the ways in which a beginning science teacher in a Korean elementary classroom engaged in collaborative research with her own students to resolve problems preventing effective science teaching and learning. Specifically, this study uses cogenerative dialogue between teachers and students to develop new teachers' knowledge of how to manage the classroom to be able to more effectively implement inquiry instructional strategies and knowledge of students as learners. Findings from this research suggest that by involving students in cogenerative dialogues, beginning teachers are provided with valuable insights into how elementary students think about school, science, and teaching and learning, which can help expand a beginning teacher's capacity to be an effective science teacher of science for all learners, especially diverse learners. These findings suggest that teacher education programs could better support beginning teachers by placing greater emphasis on how to conduct action research, including how to implement cogenerative dialogues to catalyze positive changes in their own classrooms. We conclude by discussing the important implications this research has for supporting new teachers struggle to effectively teach science and who would benefit from using strategies to foster improved relationships with their students and improved understanding about the challenges faced by diverse learners in their classroom.

This study was designed to examine the relationships between empowerment and child care teachers' intention of teaching, the reason for teaching intent. The subjects were 181 child care teachers from Chungcheongnamdo and the city of Daejeon, Korea. This study was conducted using questionnaires. The results were as follows: first, there were significant relationships between empowerment and child care teachers' intention of teaching and, the reason for teaching intent. There were positive relationships between decision making, professional growth, status, self-efficacy, autonomy, impact empowerment and child care teacher' intention of teaching and, the reason for teaching intent. Second, child care teachers' intention of teaching and the reason for teaching intent were affected by empowerment. Status and professional growth empowerment were the most predictive variables for the child care teachers' intention of teaching. The impact and self-efficacy empowerment were the most predictive variables for enjoy working with children, impact and professional growth empowerment were the most predictive variables for finding meaning in teaching, impact and status empowerment were the most predictive variables for opportunities to face ongoing challenges, and achievement motive. Status empowerment were the most predictive variable for reasonable pay and working environment, stability and skill. Therefore, status and impact empowerment were the most predictive variable for the reason for teaching intent.
