Dow later wrote additional books on design including "Theory and Practice of Teaching Art and Constructive Art Teaching." Dow also had an active teaching career. He taught first at the Pratt Institute in Brooklyn, then at the Art Students League in New York and, finally, at Columbia University's Teachers College. In his teaching, Dow emphasized abstract concepts of line, notan and color in order to arrive at a synthesis of eastern and western thought. His famous pupils, Max Weber and Georgia O'Keeffe, carried his methods even further into abstraction. One of his most influential pupils, the respected educator and printmaker Pedro Joseph de Lemos, adapted and widely disseminated Dow's theories in dozens of theoretical and instructional publications (1918-1950) for art schools.
