The document summarizes two models of curriculum evaluation: Tyler's model from 1949 and Stufflebeam's CIPP model from 1971. Tyler's model emphasizes measuring student progress towards instructional objectives. The CIPP model evaluates the context, input, process, and products of a program to facilitate rational decision-making. It assesses needs, available resources, implementation processes, and outcomes to guide decisions about continuing, modifying, or terminating an educational program.
