This paper reports on a study conducted within VIDEO-LM (Viewing, Investigating and Discussing Environments of Learning Mathematics), a video-based professional development project for secondary mathematics teachers that aims to enhance reflection on practice. The study explored VIDEO-LM sessions where Israeli teachers watched an 8th grade geometry lesson from Japan. We analyzed teachers’ discussions around this lesson and characterized main themes and reflection types. Findings suggest that watching the Japanese lesson, using the VIDEO-LM framework, led to productive discussions among teachers. The fact that the videotaped lesson was culturally “far” from the teachers’ reality provoked them to re-see everyday aspects of their practice, revealing some dissonances which promoted reflective thoughts and actions.

“这只能在日本发生吗？”：数学老师在跨文化背景下反思录像课程

本文报道了在VIDEO-LM（观看，研究和讨论学习数学的环境）中进行的一项研究，该研究是针对中学数学教师的基于视频的专业发展项目，旨在增强对实践的反思。该研究探索了VIDEO-LM课程，其中以色列老师观看了来自日本的8年级几何课程。我们围绕本课分析了教师的讨论，并描述了主要主题和反思类型。研究结果表明，使用VIDEO-LM框架观看日语课程可以促进教师之间的富有成效的讨论。录像课在文化上与教师的现实“相距甚远”，这一事实促使他们重新审视他们的日常练习，揭示出一些引起反省的思想和行动的不和谐。
