In 1968, Kohl moved to Berkeley, California, where his family lived for the next nine years. He was a Visiting Associate Professor, half time in the English Department and half in the School of Education, at the University of California, Berkeley during the spring semester of 1968. Then, he received a grant from the Carnegie Corporation of New York (September 1968 to June 1969) to work with Allan Kaprow, the "happener" who was a Professor of Art at the State University of New York, Stony Brook, on teacher education and the development of creative curriculum that crossed disciplinary and artistic boundaries. Working with Kaprow freed him to cross boundaries, work with students in theater, and experiment with interactive media. The unlikely marriage, made by Margaret Mahoney of Carnegie, had a profound influence on Kohl's teaching and thinking about learning.
