An integrated curriculum is based on the idea that knowledge and skills are synergistic’ more is gained when interrelationship are promoted than when lessons are kept isolated. This idea is supported by the theories of cognitive psychologists (e.g., Bruner, Goodnow & Austin, 1956) who conceive of knowledge and skills as being knit together by complex webs of interconnections. When interconnections are increased, learning is made easier and lessons have wider application. Student motivation is also increased when lessons in different areas of study are made.
