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…

Mathematics education researchers suggest that providing the opportunity to struggle with important mathematics (SOS) is a necessary component of lessons in order for students to conceptually understand mathematics. There are many ways to promote and support SOS, yet very few lessons demonstrate SOS in today's middle grades classrooms. This study…

This study aims to identify how mathematics teachers understand whole-class discussions and to know the influence of lesson study on the way they orchestrate these discussions. This is a qualitative study, conducted with two groups of middle school teachers. We analyze data concerning three teachers, Patrícia, Marta, and Diana, collected through…

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…

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…

In their daily work teachers are responsible for several complex tasks; might AI be harnessed to support teachers in the challenging work of planning lessons? In this paper we investigate the use of an AI tool, namely ChatGPT, to generate a lesson plan that may be of use to teachers in their planning. A carefully worded prompt, informed by…

The purpose of this qualitative, descriptive study is to explore how teachers describe the process of creating lesson plans that use drama-based instruction (DBI) in the classroom to engage students as well as how they describe their experience using DBI in the classroom to engage students. Fourteen teachers located in the state of Florida…

This study examined how preservice teachers (PSTs) develop adaptive competence in teaching peers in an introductory physical education pedagogy course underpinned by a pedagogical cycle designed to promote adaptive teaching competence. Two guiding research questions were: (a) what was the total number of adaptations that PSTs made in their peer…

The aim of this study is to investigate both the planning and implementation process of a modelling task by a middle school mathematics teacher. The participant of the study, which was conducted as a single case study, is a middle school mathematics teacher who have knowledge and experience in modelling. The data collecting tools of this study…

As middle school teachers, the authors want their students to develop voice and agency because they want them to be able to make productive decisions about how to approach mathematics, communicate mathematics, and use mathematics to interpret and transform the world in which they live. They use this article to present two vignettes that examine…

One of the challenges of understanding the complexity of so-called reform mathematics instruction lies in the observational tools used to capture it. This article introduces a unique tool, drawing from commognitive theory, for describing classroom discussions. The Realization Tree Assessment tool provides an image of a classroom discussion,…

Being outdoors encourages content creativity, inclusion of new ideas and perspectives, student voice and agency, authentic contextualization, and connection to nature. In this article, the authors share why integrating mathematics and nature is beneficial for both students and teachers, provide an example of a middle-grades lesson taught outside,…

Despite the long-time call for change in mathematics instruction, there are several barriers to change, and instruction has remained stagnant overall, taking the form of traditional lecture. Instructional coaching has many of the attributes of effective professional development from the literature and could be a major support for instructional…

Teachers' beliefs can be seen as psychological seeds planted in teachers' minds. Teachers' beliefs about effective inquiry-based teaching impact their intentions, instructional designs, and actions required for inquiry-based lessons. This paper discusses how to help Thai preservice science teachers who engaged in their student-teaching practicum…
