Σύνοψη	Lesson study (jugyou kenkyuu) is a collaborative, cyclical form of teacher professional development and practitioner inquiry that originated in Japan. A team of teachers studies the curriculum, sets a shared learning goal, jointly designs a 'research lesson,' has one member teach it while the others observe students closely, and then debriefs against the evidence to revise the lesson and their understanding of teaching. Rather than improving a single lesson, its deeper aim is to build teachers' professional knowledge through disciplined, evidence-based collective inquiry.	Formative assessment, or assessment for learning, is the practice of gathering evidence of student understanding during instruction and using it immediately to adjust teaching and to give feedback that moves learning forward. Unlike summative assessment, which measures learning after the fact for grading or accountability, formative assessment is woven into the teaching cycle. Synthesized influentially by Black and Wiliam, it is defined not by the type of instrument but by whether the resulting evidence actually changes subsequent instruction and learning.
