Jeff Ellenbogen: Makerspace Pedagogy Facilitator
New Cohort Option!

Jeff Ellenbogen is the Director of Innovation and Technology at Dawson School in Lafayette, Colorado. His career in independent schools spans over 25 years, enriching the lives of students across all grade levels. Starting as a lower school science teacher, Jeff later transitioned into teaching Middle and Upper school mathematics for 15 years before pivoting toward technology leadership and has served as both IT Director and Director of Innovation and Technology over the past decade.

He has always had a natural proclivity to explore new tools and to find ways to express himself creatively. As his career shifted from math toward technology he has found so much joy in helping students as well as colleagues solve problems and construct their own learning pathways using a multitude of tools. Providing students with authentic learning experiences where they guide their own learning pursuits has fueled Jeff’s passion for Makerspace education. Jeff loves designing projects that give students as much opportunity as possible to explore, iterate, and reflect on their work and to take ownership of their learning.

Ellie Donnell: English Facilitator
Ellie Donnell’s first teaching experience was leading a group of high-schoolers on a cross-country bike trip, where she learned the value of giving students the maps, giving them ownership of and responsibility for the trip, putting them in charge of changing their own tires, and deciding when to stop for breaks and what to cook for dinner.  For 15 years after that, she worked hard to find ways to give students the maps in her classroom.  Ellie taught English (to grades 8-12), journalism, and art history at Swiss Semester, Walnut Hill School for the Arts, Chadwick School, Marlborough School, Central Juvenile Hall in Los Angeles, and Rye Country Day, where she designed place-based courses and was involved with Round Square, service learning, and outdoor ed (and in efforts to break down the silos that so often keep school initiatives from being integrated).

Ellie recently joined the team of curriculum writers at Great Minds, where she is working to design an inquiry-based high school ELA curriculum to be adopted by school districts throughout the U.S.  She learns best by doing, and she gets excited about backwards planning, Kurt Hahn, interdisciplinary and experience-based course design, ways to shake up traditional ideas about teaching and learning, and how to make four years of high school English more authentic, more relevant, and more interesting for students. She has an undergraduate degree from Williams College and a master’s degree from Teachers College at Columbia; she loves Santa Fe, and she's thrilled to be joining the Summer Institute.

Lynne West: World Languages Facilitator
Lynne is the Interim Assistant Principal for Instruction at Bellarmine College Preparatory in San Jose, California.  As a teacher, Lynne shared her passion for language with her students.  She used her foundation in backward curricular planning and cooperative learning to design creative and engaging lessons for the students in her French and Latin classes. In 2016, she was a recipient of a Fulbright Distinguished Award in Teaching grant and spent six months conducting a research project in the Netherlands on language learning methodologies. A true lifelong learner, in 2018, Lynne started her own consulting practice and moved to Valencia, Spain where she continues to explore her love of language and culture.  Lynne has presented workshops on cooperative learning, differentiated instruction, backward planning, and teaching with technology. In her consulting work, she works to support mid-level school leaders through personalized coaching sessions. Lynne earned her teaching credential from Santa Clara University, her masters in Classics from the University of California at Santa Barbara, and her BA in Ancient Greek and Latin from the University of California at Los Angeles.  

Megan joins us from Deerfield Academy in Massachusetts, where she teaches physics and mathematics plus coaches the robotics team. Megan’s students learn experientially, including projects like studying the physics of resonance using instruments they built and by solving challenges such as Road Runner vs. Coyote. The key, she says, to teaching experientially is twofold: 1) adjust your traditional notions of “covering content” and 2) allow students the time and space to genuinely reflect on their experiences. Megan holds a MAT in Secondary Mathematics Education from Georgia State University and a Bachelor of Engineering in Materials Engineering from Auburn University.
