Reports on a research project designed to implement an adapted Lesson Study cycle whereby pre-service mathematics teachers co-create a lesson with an experienced expert instructor and observe the instructor teach the lesson. Results show development in the pre-service teachers' attention to elements of planning such as anticipation and pedagogical…

This paper introduces CoCo, a system designed to support and encourage collaborative learning among colocated students sharing a single mobile device. It provides teachers with the possibility to create digital lessons, configure parameters for collaborative activities such as the number of students and tablets, and monitor students' progress. On…

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…

"Balai Besar Guru Penggerak Daerah Istimewa Yogyakarta (BBGP DIY)" conducted a professional development course aimed at enhancing primary school teachers' capacity to develop and implement STEM lesson plans in their classrooms. As part of the course, teachers were asked to record their lessons, which were later analysed to identify the…

We examined the suggestions mathematics coaches provided to teachers as part of one-on-one coaching cycles. The purpose was to understand the object (content) of the suggestions, the lesson phase in which the suggestion would occur, and the clarity of the suggestion (how actionable the suggestion would be if the teacher followed the suggestion).…

By highlighting the curriculum modifications that lead to maintaining, or enhancing, the mathematical quality of an algebra lesson introducing the substitution method for solving systems of equations from an algebra textbook, we present an analysis of how a teacher and her students impact how the mathematical ideas unfold across the lesson and how…

Fostering students' bidirectional conception of the equal sign (viewing the equal sign as indicating an equivalence of two sides rather than a 'show result' symbol) is challenging, and students' misconception of the equal sign is persistent. Some studies mention that in China, the pedagogical approach to introducing the equal sign supports…

Mathematics teachers make numerous decisions that form lessons that in turn greatly influence what students learn. In making these decisions, teachers rely on their curricular reasoning (CR) to decide on what mathematics to teach, how to structure their lesson, and what problems or tasks to use to achieve their lesson goals. However, teachers…

In this paper, we offer a novel framework for analyzing the Opportunities for Reasoning-and-Proving (ORP) in mathematical tasks. By drawing upon some tenets of the commognitive framework, we conceptualize learning and teaching mathematics via reasoning and proving both as enacting reasoning processes (e.g., conjecturing, justifying) in the…

Worldwide interest in Lesson Study (LS) and the opportunities offered for student learning through the use of a Structured Problem-Solving Approach (SPSA), as typically adopted in Japanese LS research lessons in mathematics, have left largely unanswered questions about the extent to which these can be replicated elsewhere. This paper presents a…

In today's modern age, digital technologies are an essential part of everyone's life, so students must learn to use them in primary school. The specific competences defined in the European Digital Competence Framework DigComp 2.1 (2017) are divided into six areas. The Ministry of Education of the Czech Republic has subsequently drawn on this…

Positioning theory has been used in research to understand how elementary student teachers are positioned while working with their mentor teacher. While this research has identified four general positions, there remains a lack of clarity about these positions, particularly in how they differ. This study explores three contrasting student…

Listening is involved in daily school activities, but its importance is often overlooked and underestimated. Good teaching practices evolve from telling to listening in order to understand the needs of the student. In this paper, lesson study, a form of teacher professional development, is used as a contextual platform for developing the practice…

This case study compared preservice primary school teachers' and primary school teachers' experiences with multi-grade teaching in the 2018--2019 academic year. The sample consisted of 17 fourth-year students in the department of primary school teaching education of a public university and 14 multigrade teachers from 12 schools in Turkey. The…

The independent curriculum is designed to be a better future solution for education in Indonesia. This curriculum is expected to reduce the learning losses that occurred after the COVID-19 pandemic. In the independent curriculum at the elementary school level, natural science subjects are changed to natural and social science subjects. Natural…
