Each semester (twice a year), students in grades Five through Eight have the opportunity to provide input into special enrichment coursework of their choice that is led by a teacher with interest and expertise in that field. These special classes are developed and instructed by Middle School teachers and are called FLEX Classes; they meet last period on Mondays, Wednesdays, and Fridays.
FLEX enrichment clusters are:"...non-graded groups of students who share common interests, and who come together during specially designated time blocks during school to work with an adult who shares their interests and who has some degree of advanced knowledge and expertise in the area." (Reis & Renzulli, 2010)
FLEX experiences are designed and coached by Avon School teachers based on their own interests and talents. Check out what Scott Swaaley from High Tech High and GRITLab has to say about these types of teacher facilitated experiences:
