This article discusses a qualitative case study involving eight mathematics teachers in Brazil. The study aimed to analyze the effectiveness of a training course that combined Lesson Study and Criteria of Didactical Suitability in developing reflective competence in teachers. Lesson Study is a professional development strategy that encourages teachers to collaborate and reflect on their teaching practices, while Criteria of Didactical Suitability is a tool that guides teachers’ reflection. The study aimed to evaluate the usefulness of Criteria of Didactical Suitability in enhancing reflection skills and to assess the participants’ perception of its usefulness. The analysis revealed that participating teachers improved their reflection skills, specifically by utilizing Criteria of Didactical Suitability more effectively in the third phase of the course. However, the study has limitations, such as being conducted virtually and in a specific context. Overall, this study highlights the potential of combining Lesson Study and Criteria of Didactical Suitability in developing reflective competence in teachers. Further research can explore the efficacy of this approach in different contexts.

Currently, teachers are being challenged to integrate sustainability into school classrooms in various disciplines, and the statistics education is not immune to this trend. Against this backdrop, in this work we investigate the belief system of 11 Chilean primary education teachers who are active in statistics education and its links with sustainability. To this end, we conducted semi-structured interviews and analyzed them using a qualitative methodology under an interpretive approach. The results show that teachers acknowledge the integration of statistics education and sustainability as a challenge, identifying as the most recurring topics their mastery of content and the development of skills.

This study examines the impact of combining Lesson Study and the Didactic Suitability Criteria (DSC) for the development of teacher reflective skills. It involves six teachers in an Argentinean training program, spanning 15 virtual sessions over 5 months. Analysis of video recordings indicates significant improvement in reflective abilities, especially when using the DSC for lesson analysis. This approach enhances teaching quality and benefits student learning. The study suggests Lesson Study and the DSC are valuable tools for promoting collaboration and reflection among educators, particularly in math education. Further research with larger samples and long-term follow-up is recommended. This underscores the importance of integrating Lesson Study and the DSC in teacher training to enhance reflective competence and raise education quality.

If we are to understand and address today’s social, environmental and economic crises through education, we must introduce education for sustainable development (ESD) into classrooms and approach it from an integrated perspective. In so doing, this study aims to provide an overview of the current status of the still-emerging research agenda on the integration of ESD into mathematical education and statistical education. To this end, we conducted a systematic review of Scopus and Web of Science databases of theoretical and research articles published between 2010 and May 2023. In total, 32 studies were identified, conducted mostly in Europe, followed by South America, which mainly address teacher training. The results suggest that mathematics education and statistics education are an effective means of providing education focused on ESD, but that teachers still have limited knowledge and resistant attitudes. Therefore, initial and ongoing training must move towards characterizing proposals that provide examples and involve teachers in response to this challenge.
