Using 48 college texts, comparisons were made of Dale-Chall Readability Formula results based on samples taken from various page intervals. (HOD)

Validity, the most critical of readability formula characteristics, requires that a measuring device actually measure what is intended to be measured. To examine validity, a study was conducted in which ten popular handbooks used in the teaching of college freshman composition were examined for comparative validity data--the extent to which scores…

The Flesch reading formula is questioned as being appropriate for evaluating college economics textbooks. The Dale-Chall, Modified Dale-Chall, Fry, and Flesch formulas were used to evaluate nine introductory textbooks. There was little or no consistency in either the absolute reading levels or the rank orderings. (Author/AM)

The study reported in this paper was designed to describe the differences between the reading-difficulty levels of primary textbooks used in first-semester freshman general studies courses and the reading skills of the students enrolled in those courses, and to compare the Flesch Reading Ease Formula with the SMOG Grading Formula. Separate…

The first phase of a study investigating textbook readability and students' reading levels used three traditional formulas to assess the readability levels of 51 primary textbooks from college introductory social science courses in 7 disciplines. The second phase investigated the relationship between the readability levels of students' texts,…
