Thumbs up to the newest slate of Master Teachers, a group which includes three more Chautauqua County teachers. David Doty of Cattaraugus-Little Valley Central School, Amy Lauer of Fredonia Central School and Paula Ferneza of Frewsburg Central School were among 215 teachers included in the second round of selections for Gov. Andrew Cuomo's New York State Master Teacher program. Eligible teachers must be ranked highly effective under the state evaluation system, have at least four years of experience and teach math or science in sixth through 12th grades. Among the duties of Master Teachers are peer mentoring and content-oriented professional development opportunities throughout the academic year, working closely with pre-service and early career teachers to foster a supportive environment for the next generation of STEM teachers, attending required regular cohort meetings, participating in and leading several professional development sessions each year and participating in the training of pre-service and early career educators. Such programs shouldn't replace a school district's teacher training program, but the collaborative environment the Master Teacher program fosters is certainly a positive thing.
