David G. Kyle, 56, an associate professor of education at the University of Maryland, died Wednesday at Doctor's Hospital of Prince George's County after suffering a cerebral hemorrhage.

He also was assistant director of the Institute for Child Study in the College of Education at the university. He specialized in the field of human development and worked mainly with teachers in helping them to understand better their students' behavior.

Dr. Kyle had been a teacher and institute staff member in the College of Education since 1962. He was named assistant director of the institute in 1976.

One of his main projects was establishing programs leading to master's degrees in human development of two University of Maryland extension schools in the state.

Dr. Kyle also had worked with Head Start, with educational television and with religious educational groups. He had published articles in education and child development journals.

He was born in Wheatland, Wyo., and grew up in Brighton, Colo. A graduate of the University of Denver, he also received a master's degree there and later earned a doctorate from the University of Maryland.

Dr. Kyle served with the Navy Hospital Corps during World War II. Before coming here he had worked with the public school system of Kings County, Calif., as a psychologist, guidance consultant and child study coordinator.

In 1965, Dr. Kyle, who lived in New Carrollton, received the University of Maryland's Excellence in Teaching Award.

He is survived by his wife, Mary Ann, of San Diego, Calif., and a daughter, Kathryn, of Albuquerque, N.M. CAPTION: Picture, DAVID G. KYLE
