If you’ve ever started a new Unit of Study and wished you had a knowledgeable colleague right beside you—someone who could help you see the arc of the unit clearly, tell you what to prioritize, and prepare you for what’s coming—Mossflower Learning was built for you.
Today, we’re excited to introduce Mossflower Learning, a new on-demand professional learning platform from The Reading & Writing Project at Mossflower (RWP-M). It’s designed specifically for teachers, literacy coaches, principals, and school leaders who are implementing the Units of Study in Reading and Writing.
What Is Mossflower Learning?
Mossflower Learning is a library of on-demand courses that offer practical, classroom-ready implementation support for the Units of Study—on your schedule, at your pace.
Each course focuses on a specific grade level in either reading or writing. Within each course, every lesson carefully unpacks a single unit of study—helping you understand not just what to teach, but how and why it works. The courses are created and led by Mossflower Staff Developers and authors of the Units of Study themselves—the people who know this curriculum most deeply.
Who It’s For
Whether you’re a classroom teacher preparing to launch your next unit, a literacy coach deepening your knowledge before supporting a new grade level, or a school leader looking to give your staff consistent, flexible support, these courses meet you where you are. Mossflower Learning is designed for individual educators who are teaching the Units of Study and want a supplement to their on-site professional development.
Mossflower Learning can also be helpful for long-term substitute teachers needing to get up-to-speed, new teachers who need quick onboarding of the units before diving in more deeply with PD, and more.
What You’ll Find Inside Each Course
At launch, Mossflower Learning includes courses for Kindergarten through Grade 5 in both Units of Study in Reading and Units of Study in Writing—12 courses in total, with more on the way.
Each grade-level course includes one lesson per unit of study. In every session, Mossflower Staff Developers unpack:
• The big goals and essential understandings of the unit
• Key teaching moves and instructional priorities
• Practical planning guidance you can use right away
• Differentiation strategies to support all learners
• Tips for pacing and preparing your materials
The recommendation is simple: watch each lesson a few weeks before you launch that unit. Keep your Units of Study materials nearby. Take notes as you plan. Then revisit whenever you need a refresher or a reset.
Flexible, Year-Long Access
When you purchase a course, you have 365 days of access from the date of purchase. That means you can watch before the unit begins, return mid-unit when a lesson isn’t landing the way you hoped, and plan in a timing that works for your specific scope and sequence.
Each course includes approximately one hour of content per unit—roughly 4-5 hours total. It’s professional learning that fits into real teacher life, not the other way around. Your time, your way.
Earn Certificates of Completion
Upon completing a course, you’ll receive a certificate of completion documenting your clock hours, delivered directly to your inbox. For educators tracking their continuing education hours, this makes Mossflower Learning a practical and credentialed choice.
Built by the Authors You Already Trust
Time is precious, and not every PD opportunity delivers real classroom value.
Mossflower Learning is special because the people guiding you through each lesson are the same people who wrote the curriculum itself. The staff developers who lead these courses have spent years supporting teachers in classrooms, coaching across grade levels, and refining the instructional moves that make the Units of Study work. Every lesson reflects that depth of experience—research-backed, and classroom-tested.
Enrollment Opens June 1
Mossflower Learning officially opens for enrollment on June 1, 2026. Courses are available for individual purchase at $500 per course.
