What is TXLS?

Proven Process



Lesson study is a proven process in which teachers drive improvements to teaching and learning through collaborative action research.

Continuous Improvement


In Lesson Study, teachers engage in cycles of continuous improvement. Together, groups of teachers examine a problem of practice, plan instructional solutions, teach, observe, reflect, and share the results of their work.

Deep Understanding



The product of Lesson Study goes beyond perfecting a single lesson. Working together to plan, practice, and reflect, teachers develop a deep and lasting knowledge of content and pedagogy.
