Statement of the Problem: In a unit of study in Earth Science, such as Astronomy, there is a great deal of background material which is not covered in the textbook. It was the writer's purpose to attempt to determine whether ninth-grade students would master the subject faster and more completely if this material were taught before beginning the study of the unit in the text. Methods and Procedures: Two of the writer's classes were chosen for comparison. The students were matched as well as possible from the standpoints of sex, general intelligence, and previous grades earned in Earth Science. In the Subject of Astronomy, one class was pre-taught the background material while the other was not. The classes then were reversed for a second topic, which was Diastrophism and Vulcanism. Judgments were made on the basis of the amount of improvement by the students from a pretest to a post-test over both the background material and the unit in the textbook. Summary of Findings of the Study: There appeared to be little difference in achievement by the students with either method. The data actually indicated a slight advantage to the method in which the background material was ignored.
