Educational practice itself is in a state of great transition as many nations seek to adapt teaching and Learning activities in an effort to revitalize students' motivation and performance. One such measure, termed 'formative assessment', is a classroom assessment practice that is becoming the heart of the educational framework. This practice promotes continuous learning and assessment dialogue among students and their teachers, creating and sustaining their collective learning identity as respectful and successful group members. Research 'knows' that social engagement has profound psychological effects. It is, therefore, of particular interest to discuss how the interactive instructional methods that characterize 'formative assessment' interplay with the high level of collective action required of Japanese people. This is given a rich socio-cultural context by chaotic aftermath of the catastrophic 9.1 earthquake, named for its magnitude as the Great East Japan Earthquake of 2011. It is in the selfless responses to this event that the words "quiet dignity" refer. These attributes of identity have formed across centuries in unique cultural circumstances, and by their theoretical similarity parallel the core elements required for formative assessment, otherwise known as Assessment for Learning (AfL). The cultural development of the Japanese nation sanctions harmonious and reciprocal group action as the sine qua non of a functional society. This fact supports the proposition that Japan is a naturally hospitable research and development context for AfL. Consequently, many aspects of AfL have presented themselves in Japanese Lesson Study (jugyo kenkyu) plans since the 1910s. The authors provide unique insights into the culturally embedded pedagogy and assessment. The article is rationalized around indigenous words (e.g. kaizen) steeped in deep cultural meaning thousands of years of in the making. When these key terms are explored, they introduce the Western practitioner to novel yet familiar ideologies that assist active practitioners everywhere with their efforts to explore alternative assessment practices and revitalize traditional methods. These terms are key to an understanding about the exportable nature of indigenous assessment methods when they are designed to promote deep learning (internalization), and sustain collective motivation (social cohesion). This article emphasizes those particular aspects of Japanese cultural tradition that drive effective assessment, create well-rounded (zenjinteki) students, and prepare young adults for success in life. The authors take various approaches, exploring how classroom assessments are embedded into instructional process around the world, and how these may be creatively integrated with Japanese perspectives on classroom learning and assessment.
