The Tyler curriculum model was first introduced by Ralph Tyler in 1949. Both John Dewey and Edward Thorndike had a huge influence on his curriculum development model. The students' emotions, feelings, intellect, and beliefs are what helped Tyler to design his curriculum model. His model consists of four parts, which are the instructional strategies and content, objectives, organization of learning experiences, and assessment and evaluation. The Tyler model focus is solely on teaching and the objectives serves as a basis for devising elements and reflecting on the degree of achievement of the objectives.
