The results of a curriculum evaluation can be used in inservice sessions as a focal point for decision-making by classroom teachers. Among the questions that may be asked during a curriculum evaluation are: (1) How well do students achieve the stated objectives of the curriculum?; and (2) At what points in the instructional sequence does instruction need to be modified? By looking at student performance on each objective of the curriculum, answers to these questions can be obtained. This may be accomplished by evaluating the results of pre- and post-tests. This approach to inservice decision making was tested by science students and teachers at three junior high schools. (BB)
