Adapted from curriculum written by Susan Dangel, Maria Garriott and other contributors at the Johns Hopkins University School of Education. As part of their work for the Talent Development Secondary (TDS) program, they created extensive teaching materials to accompany Joy Hakim's award-winning ten-volume series, A History of US. With over 15 years of experience, TDS brings engaging instruction, solid organization and student, teacher and administrative support to dozens of schools across the nation. TDS brings the right supports to the right students at the right time, helping all students on the path to college and career readiness. Because TDS curricula are research based and practice validated, they incorporate the latest insights and best practices from brain research, sociological studies, and teacher feedback.
