It is seen that there are few studies on the role of the knowledgeable other when the literature on Lesson Study [LS] is examined. However, for LS to be better understood and applied in different cultures, the role of the knowledgeable other in LS process should be clarified. This study aimed to determine the role of the researcher as the…

The aim of the study was to test the effect of teachers' professional development upon students' mathematics academic achievement levels with the help of lesson study. In this manner, the study aimed at increasing students' mathematics learning levels via lesson study. Action research was used as research method in the study. The sample of the…

Global climate change is one of the most significant challenges of the twenty first century, requiring its integration into K-12 science education curricula to foster informed and climate-literate citizens. However, challenges remain in effectively teaching climate change, including a lack of instructional materials and a reliance on traditional…

Purpose: This study aimed to determine the expectations of students from mathematics teachers in the planning phase of lesson study (LS) in mathematics classrooms.

This research examined how pre-service mathematics teachers (PMTs) plan to support argumentation in their lessons about the hierarchical relationships among the quadrilaterals and what they notice during planning. The participants of this case study were eight pre-service middle-school mathematics teachers. Data consisted of the PMTs'…

This study explored four middle-school mathematics teachers' provision of non-examples and instructional explanations in teaching rational numbers to seventh-grade students. The data sources were 8 lesson hours of observations conducted in four different classrooms. Yin's [(2018). "Case study research and applications: Design and…

The purpose of this study was to, first, examine the potential of lesson plans (LPs) of preservice science teachers (PSTs, N = 631) as a source for gathering rich data on their pedagogical content knowledge (PCK) and, second, qualitatively describe PSTs' reasons for the level of data richness in their LPs on PCK. PSTs' handwritten LPs were…

Reading comprehension questions scaffold deeper comprehension, help students to analyze texts, improve students' thinking skills, and help them realize permanent and meaningful learning. By comparing reading comprehension questions used in Turkish lessons with student-generated comprehension questions in terms of level, this study aimed to…

The STEM learning approach, which integrates science, technology, engineering, and mathematics disciplines, is increasing its popularity in all countries. Countries are trying to ensure that students develop their cognitive, affective, and scientific process skills by integrating the STEM learning approach into their education systems. In this…

The purposes of this study were to explore how a science teacher and a mathematics teacher collaborated for science and mathematics integration with the support of a researcher, to describe the process of planning and implementing integration and to understand the main issues considered by teachers during the process. Observational case study was…

The study aimed to explore the integration of lesson study into science teacher education programs to enhance preservice science teachers' pedagogical content knowledge (PCK) for STEM. The lesson study cycle encompassed planning, teaching, reflecting, re-teaching, and re-reflecting phases, and the participants' experiences regarding PCK for STEM…

This paper aims to examine the extent to which pre-service teachers' mathematical connection skills were promoted through the course designed within the scope of pedagogies of practice (Grossman et al. [2009]. Teaching practice: A cross-professional perspective. Teachers College Record, 111(9), 2055-2100.…

This study was a case study and the participants of the study was 11 middle school mathematics teachers in three different school in a city at central Anatolia region of Turkey. Three lesson study cycles…

It was aimed to examine pre-service teachers' developing understandings of doing statistics within a lesson study. It was focused on their understandings (i.e., content knowledge) of doing statistics as well as how they transform their understandings (i.e., content knowledge) into teaching practices (i.e., knowledge of student & knowledge of…

This embedded-single case study aims to evaluate the efficacy of the 8th-grade music curriculum through the lens of Eisner's Educational Connoisseurship and Criticism Model. An initial survey involving 146 music teachers was conducted to determine the middle school grade-level music curriculum for evaluation. Subsequently, 15 music teachers, six…
