NTTI advances an interactive teaching methodology in which video and telecommunications merge with hands-on activities to enhance critical thinking, motivate student learning, and sharpen students' perceptual skills. Public television's wealth of educational programming provides students with vivid demonstrations of subject matter. Tied to real world settings and contexts, video and Internet resources help make the connection between curricula and students' own lives and futures. Video is also a good vehicle for presenting students with a range of diverse role models working in various fields. The NTTI model is based on teachers teaching teachers.
