Abstract
The purpose of this investigation was to compare the question answering of good and poor readers when their prior knowledge for the answers to questions was determined before reading to be accurate, inaccurate, incomplete, or missing. Fifty-six fifth-grade students with equivalent I.Q.'s, but varying in reading ability and extent of general prior knowledge for the passage topics, participated in the study. Subjects read an expository passage written on their approximate instructional reading level. The results indicated that poor readers did not use prior knowledge to the same extent as did good readers. This was especially true when students were learning new information. The results also suggest that poor readers have difficulty answering text implicit questions even if they possess adequate prior knowledge for passage topics.
