This qualitative study aimed to identify the changes in a prospective' conceptions about the nature of mathematical tasks and pedagogy in video cases and to investigate the characteristics of the prospective' professional knowledge and views during task design/modification. The study used the mathematical task demand engagement process, which…

This paper describes and analyzes three cases to show the impact that curiosity-driven (CD) discourse based on self-video can have on the professional awareness and noticing skills of mathematics teachers and instructors of mathematics teachers. The findings indicate that CD discourse raises awareness of heretofore unnoticed events in the lesson,…

This study focuses on how science teachers' Pedagogical content knowledge (PCK) can be captured and developed with the support of Content representation (CoRe) in combination with video-based reflection when they plan, teach, and reflect on their teaching in sustainable development (SD). The theoretical framework is based on PCK, and the Refined…

Background: Effective science teaching requires a specialised body of knowledge. Researchers have recognised the importance of understanding the incoming knowledge that pre-service science teachers (PSTs) bring to their initial teacher education. However, although many studies have focused on PSTs' declarative knowledge or the knowledge that…

Teaching science to elementary school students is complex, and teacher preparation programs must support pre-service teachers' learning to communicate science content and practices with children. Science teachers bring the experiences they have as students to their teacher preparation, and these experiences may support or conflict with what they…

Since 2020, teaching has gone through substantive transformation. Teacher educators have been compelled to reevaluate their instructional strategies and the use of technology to deliver effective training for pre-service teachers. The year 2020 escalated the use of teaching strategies that relied on technology as a crucial tool in all teaching…

This article provides robust empirical evidence for the association between science teachers' pedagogical content knowledge (PCK) and student achievement. Unlike previous studies, we employed two approaches (text-based vs. video-based tests) to assess if, and to what extent, teachers' PCK assessed by these two approaches are related to student…

Video-based flipped learning (VFL) has become a popular form of flipped learning. However, teachers' technological pedagogical content knowledge (TPACK) for video-based flipped learning is still under-explored. A TPACK-VFL questionnaire for assessing teachers' TPACK for VFL was developed and validated with both EFA and CFA in this study to fill…

This paper studies the knowledge developed by a group of sixty-two pre-service primary teachers during a training session on the definition of a polygon and the mathematical practice of defining. We explore the knowledge developed by pre-service teachers when they carry out a series of training tasks oriented around the practice of defining with…

Professional teacher noticing is a key skill in preparing future elementary mathematics teachers, with the goal of increasing the specificity and sophistication of noticing children's mathematical reasoning. One common effort scholars have engaged to improve teachers' professional noticing is to improve the quality of representation. Recently,…

Pedagogical content knowledge (PCK) is an important target of science teacher knowledge assessment. Most studies that have assessed the PCK across a large sample of science teachers used a text-based approach to elicit and assess the more declarative and static form of teachers' PCK. Recently, small-scale qualitative studies have adopted a novel…

The scalability and accessibility of quality professional development (PD) is an ongoing concern in the teacher education community, yet little research has been conducted on potential solutions. We aimed to address this gap by developing an interactive, virtual PD program that uses intelligent tutoring systems and provides instant feedback to…

This paper presents Big Ideas of Measurement as a framework of students' thinking about measurement. Drawing from research-based evidence, the framework is a collection of key concepts that students must develop for a robust understanding of measurement and, as such, are key aspects of students' thinking teachers should learn to notice. In a case…

Fractions remains a difficult topic for primary preservice teachers (PST). This paper analyses a PST teaching episode using the "Refined Consensus Model" (RCM) of Pedagogical Content Knowledge (PCK) to explore challenges faced by PST in acquiring specialised knowledge for effective fractions teaching. Data include semi-structured…

The purpose of this study is to identify the factors that shape pre-service teachers' (PSTs) online teaching practices within the technological pedagogical content knowledge (TPACK) framework. Ten science PSTs and nine mathematics PSTs who experienced the practical part face-to-face and the theoretical part online of the Teaching Practice 2 course…
