Older student reading of informational texts like those found in most high school classrooms continue to be a concern. College entrance exams scores attest to the fact that this age group of readers remain largely unprepared for the rigorous, discipline area reading and comprehension demands of higher education. In response to this issue content area teachers have been encouraged to teach reading skills for their subject matter. Standard reading instruction tools have included reading guides and summative reading assessments. This study sought to compare the effects of standard reading pedagogy with computerized, formative reading assessments given to students as they read. The largest publisher of high school textbooks, Pearson Prentice-Hall, and the publisher of the high school government text used in this study currently does not have in place digital, formative reading assessments tracking section by chapter section. High school seniors in nine sections of American Government under two different instructors participated in this mixed method, quasiexperimental study. Results indicate a significant difference in content comprehension with the formative assessment pedagogy. Survey and questionnaire responses suggest students thought they read better and were more motivated to read responding to computerized formative assessments (CBA's) that closely tracked their subject matter textbooks.
