TTP Network

Empowering Educators through Collaboration for Student Success

About the TTP Network

TTP Network is a volunteer organization of educators and researchers designed for teachers and schools that use or plan to use a pedagogical approach called Teaching Through Problem-Solving (TTP). This approach uses problem-solving as the process for student learning to nurture students to become independent problem solvers. The TTP Network is led by researchers in mathematics education and teacher education who study teaching and learning mathematics and agree to freely provide resources and guidance to the community of educators to support them in improving teaching and learning.

All the resources and professional development opportunities this TTP Network provides are freely available for the members. Also, the TTP Network will allow members to interact with other members and network leaders regularly.

IMPULS-Lesson Study Alliance 2026 Lesson Study Immersion Program

June 16 (Tuesday) to June 25 (Thursday), 2026

The program offers educators a unique opportunity to immerse themselves in authentic mathematics Lesson Study in Japan. Participants will observe several mathematics lessons, Teaching Through Problem Solving,  developed through Lesson Study in elementary schools, and observe how Japanese teachers conduct their post-lesson discussions. All research lessons and post-lesson discussions will be simultaneously translated into English by experts in mathematics teaching and learning. In addition, participants will have opportunities to interact with teachers, students, and education professors from schools and universities in Japan.

IMPULS Immersion programs have been offered annually since 2012 (except 2020 & 2021). Over 450 educators from 15 countries have participated. They have described it as a life-changing experience and have used their experience to support colleagues in implementing Lesson Study in their schools and home countries.
