This study investigates the characteristics of Japanese primary school mathematics lessons that adopt a problem-solving approach. We argue that these characteristics are reflected in three key aspects: collective teaching and learning, the lesson as a "drama" (i.e., its structured flow), and the focus on mathematical knowledge. In this…

This study introduces a framework for analyzing opportunities for mathematical reasoning (MR) in school mathematics, using MR-relevant claims and their derivation as the unit of analysis. We contend that this approach can effectively capture a broad range of opportunities for MR across various teaching situations. The framework, rooted in…

Sustainable education is becoming a burning concept in debates and discussions the world over. There are concerns that current systems of education are not providing for the needs of all people in a sustainable way. Many countries are taking steps to ensure a type of education that will not only sustain their citizens but will meet the challenges…

Peer feedback provides a powerful tool for student learning; however, there are challenges associated with feedback. This paper draws on a feedback cycle to support 13 mathematics secondary preservice teachers (PTs) to provide feedback on their peers' lesson plans. PTs were randomly assigned to provide feedback on a lesson plan which had been…

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…

This study employed a qualitative research design to investigate the utilization of soft pedagogical documents among twelve mathematics teachers in five purposively sampled public secondary schools. Data was collected through interviews and analyzed thematically. The study, rooted in social constructivism theory, discovered a mixed pattern in the…

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…

This study investigates how pre-service mathematics teachers (PMTs) develop the capacity to plan mathematics lessons regarding reasoning and proving (R&P) at a time of curriculum change in Norway. Lesson planning poses challenges for both pre-service and experienced mathematics teachers. In this EU-funded intervention study, PMTs were led…

Nicolas Senior shows how EMC3 's Launch-Explore-Summarise/Review model for mathematics lesson structuring sets the conditions to get the most out of both dialogic and direct instruction. He argues that this model will help teachers walk the balance between order and chaos.

This research focuses on prospective teachers who are a group that has a key role in teaching mathematics to future generations. A qualitative approach with an ethnographic design is used to understand and explain the culture and social life of a region by relating its role as a learning resource to developing local culture-based mathematics…

The initial teacher education courses for Mathematics aim to promote an adequate education in mathematics and mathematics didactics. Equally or even more important than this education is understanding how the preservice teacher should build new knowledge from the activities they undertake. Considering the teaching practicum, this study aims to…

The purpose of this study is to examine how preservice middle-school mathematics teachers connect mathematics with museum resources in their lesson plans. Nine museum-based mathematics lesson plans developed by preservice teachers were examined, based on the interactive experience model. The findings showed that although the preservice teachers…

This research focuses on enhancing critical thinking in secondary mathematics education using carefully constructed teaching materials. Utilizing socially open-ended framework, complemented by perspectives from critical mathematics education, the study aims to promote students' critical thinking skills. The developed materials were implemented in…

The present study, carried out in the context of a Teacher Professional Development (TPD) Program on mathematical modelling and digital technologies, focuses on how Italian mathematics teachers refer to digital technologies in designing their lessons and investigates to what extent the TPD program impacted the way by which teachers design their…
