This article presents an extension of the well-known TPACK model to describe the professional digital competencies of mathematics teachers. The extension leads to what we want to call MPC-model (Media-Pedagogy-Content) in the following. It additionally includes (1) the consideration of competencies instead of knowledge for a holistic description,…

Mathematics teacher educators have suggested preservice mathematics teachers' (PMTs') practices provide evidence of their mathematical knowledge for teaching (MKT). PMTs engage in approximations of practice to rehearse teaching. To explore connections between MKT and PMTs' practices, we operationalized six MKT subdomains in terms of approximations…

Focussing on teachers' subject pedagogical actions over the course of a series of lessons on a mathematical topic, this paper sets out an original analytical approach to characterise the shape of mathematics teaching decisions made over time: tri-polar analysis. The notion of manifestation is introduced as a way of categorising how the teacher is…

During the industrial revolution, the quality of education improved, and this was reflected in competent and professional teachers. Teacher professional competence can be achieved by combining personal, scientific, technological, social, and spiritual skills.. This study aims at assessing prospective teachers' professional abilities in developing…

Do teachers truly demonstrate their knowledge, beliefs, and feelings about teaching L2 speaking? It is an important question to consider because teachers' cognition functions as an important element that EAP instructors should not overlook. This intrinsic case study attempts to demonstrate the disparities between teachers' perceptions of teaching…

The study aims to explore how pre-service mathematics teachers reveal their knowledge of infinity during the lesson planning process in the context of limit. Specifically, we adopted the dimensions of mathematics teachers' specialized knowledge, which are related to mathematical knowledge and its relation with teaching. We conducted an exploratory…

Since pedagogical content knowledge (PCK) influences the teaching learning process, it has dominated research on teacher effectiveness. This case study explored teachers' enacted topic-specific PCK (TSPCK) during the biology lesson study stages: planning, teaching, and reflecting. The enacted TSPCK in two video-recorded research lessons was…

Mathematics teacher educators have suggested that preservice mathematics teachers' (PMTs') practices provide evidence of their Mathematical Knowledge for Teaching (MKT). In an effort to explore connections between MKT and PMTs' practices, we developed a framework that operationalizes Ball et al.'s (2008) six MKT domains in terms of approximations…

This study sought to investigate what dimensions of didactic-mathematical knowledge preservice teachers discussed when engaged in lesson study and how lesson study supported the preservice teachers in implementing reform-minded teaching of mathematics. We employed an interpretive case study methodology with the intent of conceptualising the lesson…

As teachers plan for instruction, technology integration is an important factor in the planning and implementation process. This has become imperative in a virtual learning environment for instructors to be competent (Gregory & Lodge, 2015). Problems exist with integrating technology that aligns with teaching and learning in content areas.…

Purpose: The purpose of this paper is to examine how teachers engaged in curriculum deliberation through lesson study (LS) and how different types of teacher knowledge were elicited, co-constructed and transformed in integrated ways across LS stages. It also clarifies how different school-level orientations influence the nature, depth and scope of…

Teachers are constantly involved in the act of decision-making in every moment of the classroom. These decisions are underpinned by pedagogical reasoning, which entails situated knowledge about particular teaching episodes and is reconstructed through teaching practice. The present case study sought to explore the pedagogical reasoning skills that…

With the rapid globalization occurring all around the globe, educational landscapes also underwent some dramatic shifts. Enhancing teachers' learning awareness can be done by conducting lesson studies. Lesson study itself is a collaborative project where the teachers can share their knowledge and skills to improve teaching performances…

This study, which was conducted in 2016-2017 academic year, scrutinized the impact of a purposefully designed professional development program titled 'NOS-PD' on the understandings of the Nature of Science (NOS) via instructional practices. Specifically, the purpose of this qualitative multiple-case study was to delineate the impact of a NOS…

Early childhood professionals are sometimes referenced as caregivers and other times as educators. In order to empower them as professionals, it is important to provide professional development opportunities that deepen teachers' knowledge. This qualitative case study explores the impact of Lesson Study on four early childhood teachers with no…
