2020 CELF Summer Institute: Reimagined

NOT another webinar … an experience worth having!

Now more than ever, educators are faced with the challenge of preparing students for a rapidly changing 21st century world. We’ve listened to the K-12 educator community and are prepared to support YOU with learning insights, innovative tools designed  to the unique demands of virtual learning and approaches sensitively geared to students adjusting to unsettling changes to their daily routines. This summer CELF will offer best practices in digital learning while incorporating the principles and practices of Education for Sustainability. 

CELF will offer two Institutes of standards-aligned, credit-based virtual programming, geared towards a national audience of K-12 educators. The 2020 Summer Institutes, reimagined as an online immersion program, will inspire, educate, and reignite our collective commitment to educating for sustainability.

The Summer Institute: Reimagined will harness the imagination and energy of our educator community so you are prepared to return to the real and/or virtual classroom with new energy in the fall. 

Interactive, in-depth, and self-paced, CELF’s online Institutes are designed for individual or group participation and clearly connect course materials to real-world practice.

From the beginning, CELF has embraced the value of in-person learning and hands-on support for educators. Over sixteen years of Summer Institutes, professional development workshops, and classroom visits have produced a vast knowledge base and built strong relationships with schools and districts across the country. Along the way, CELF has also innovated with online toolkits, resources and webinars, and that forward thinking is exactly what is called for now.
