More About TRU+LessonStudy

TRU+LessonStudy uses Dr. Alan Schoenfeld’s Teaching for Robust Understanding (TRU) Framework to guide groups of teachers through a series of engaging professional learning community sessions. Fully prepared slides, embedded videos, facilitation guides, and group activities focus on connecting math teachers with their students and with each other like never before. Sessions can be led by a district coach, math curriculum specialist, or by a teacher-leader. 

Year One is focused on learning about the Teaching for Robust Understanding Framework (TRU) and ways to explore it through a series of mini-cycles of inquiry. 

During the TRU-centered phase, teams explore: 

  • The big ideas in high school math and the most important mathematical concepts
  • Ways for students to think more deeply and make sense of things more independently
  • Approaches to instruction that promote the participation of all students
  • Strategies to promote student “ownership” of their math learning and contributions
  • Assessment of student learning through dynamic events and authentic discussion

Many teams then choose to move to a second phase during which the teacher-led practice of Lesson Study connects teachers even more deeply as they pursue questions collaboratively in PLC sessions and in each other’s classrooms. Renowned Lesson Study expert Dr. Catherine Lewis worked with SERP to bring together key aspects of this time-tested approach with key aspects of the TRU Framework. 

Year Two uses Lesson Study as a vehicle to explore questions about mathematics instruction more deeply as a team. 

During the Lesson Study phase, teams conduct cycles inquiry by:

  • Establishing a research theme and selecting a topic
  • Collaboratively planning and teaching a research lesson
  • Observing and analyzing lesson elements
  • Reflecting and building a deeper understanding of practice and content
