Pearl Abiti is entering her second year at Charlestown Nursery School. Pearl joins us from a Reggio Emilia-inspired school at the University of Vermont, where she taught Pre-K for two years. Pearl is a licensed teacher and earned her Bachelor of Science in Early Childhood Education at the University of Vermont, where she was also a student-athlete on the UVM Track Team. She was the team caption, heptathlete, gold medal pentathlete, and all-around indoor MVP winner. Her athleticism and joy for movement are both present in her work with children. Pearl strongly values relationships and creating authentic experiences in a dynamic learning environment. Whether it is inside the classroom or in the natural world, Pearl’s work reflects her value and respect for children as competent citizens. She is constantly finding inspiration and ideas from the educators in Reggio Emilia and through professional development and conferences nearer to home. Pearl is honored to have visited three Reggio-inspired schools in New York City in the last year. She believes that children are curious and learn best through exploration and play that is thoughtfully guided by their teachers. Recently, she has started Reggio-inspired Affinity PLAYgroups for early childhood educators and children ages 3-8. Outside of the classroom, Pearl enjoys staying active and spending time with friends and family.
