Combating a 47% failure rate of 11th grade history students for whom a passing grade is required for graduation, the district, Trinity College, Connecticut Historical Society, and museum educators will partner to provide American history teachers in grades 8, 10, and 11 with introductory and advanced professional development workshops and lectures designed to expand teacher content knowledge and improve the quality of teaching. A teacher-in-residence, historian-in-residence, master teachers, and project meetings and newsletters will help transfer innovations and methods to all history classrooms. Resource Activity Packets make reproductions of primary sources, artifacts, music and other learning available to all history teachers, enhancing the teaching of early American history in 8th grade, 19th century in 10th grade, and 20th century in 11th grade. Intended as a model approach for underachieving schools, the project will be presented at state historical conferences for possible adoption by other districts.
