When it comes to education, many people have different opinions about how children should learn things. A psychologist named Jerome Bruner had his own theory regarding education. Bruner is a very intelligent man himself, who went to school to study and learn about many different types of psychology to completely understand human beings to the best of his knowledge. He tried to learn about cognitive growth and learning so he could help children in the future. This is what helped him develop his theory into what it is today. Jerome Seymour Bruner was born on October 1, 1915. Jerome earned a bachelor's degree in psychology in 1937. In 1939 he continued his education to a master's degree and then a doctorate in 1941. Bruner made many contributions to different types of psychology such as: Cognitive psychology and cognitive learning theory in educational psychology.
