Susan Harris MacKay is currently the Director of the Portland Children's Museum Center for Learning, which includes Opal Public Charter School and Opal Museum Preschool. She has a degree in English from Vassar College and an MAT from Lewis and Clark College. Her teaching career began when she discovered the potential of writer’s workshop to invite young children to make their voices public and imagined the power in that potential to change the world. Later, she discovered the concept of the 100 Languages from Reggio Emilia, Italy where adults were inviting the very youngest children to become citizens by making their ideas and experiences visible long before they could write. These days, Susan writes and presents about what is being learned in Opal School classrooms as students and teachers use the 100 languages to express their powerful ideas and inspire the new possibilities for environments that support playful inquiry, creativity and the wonder of learning. Susan gives leadership to inquiry-based approaches through the languages of the arts and sciences for Opal School and Museum programs. She works in collaboration with Opal School teachers and Museum educators to document children’s learning and provides professional development opportunities for educators worldwide.
