Jerome Bruner is notable for integrating Piaget's cognitive approaches into educational psychology. He advocated for discovery learning where teachers create a problem solving environment that allows the student to question, explore and experiment. In his book "The Process of Education" Bruner stated that the structure of the material and the cognitive abilities of the person are important in learning. He emphasized the importance of the subject matter. He also believed that how the subject was structured was important for the student's understanding of the subject and it is the goal of the teacher to structure the subject in a way that was easy for the student to understand. In the early 1960s Bruner went to Africa to teach math and science to school children, which influenced his view as schooling as a cultural institution. Bruner was also influential in the development of MACOS, , which was an educational program that combined anthropology and science. The program explored human evolution and social behavior. He also helped with the development of the head start program. He was interested in the influence of culture on education and looked at the impact of poverty on educational development.
