The Fry Graph for Estimating Readability (Extended) and George Magginnis' formula for passages shorter than 100 words were used in an investigation of the reading levels of 18 mathematics textbooks produced for grades one through six by three major publishers. The results indicated that the readability levels of the textbooks were inaccurate. Few…

A new, computerized readability assessment program was developed to verify the reading levels of stories, as designated by publishers in current sixth grade reading texts. The Spache, Harris-Jacobson, Dale-Chall, Flesch, and Fry readability formulas were incorporated into one computer-based program designed for rapid calculation and comparative…

Four readability indices that focus on the ease of comprehension of printed material are applied to industrial education textbooks for senior high school students. Grade reading levels by subject areas for the four indices are presented in tables, charts, and text. Certain conclusions about the readability techniques studied are suggested. (MF)

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…

Two readability formulas were applied to two math and two reading series textbooks at the fourth, fifth, and sixth grade levels to see whether the publishers' suggested reading levels were accurate. Five samples were taken from each text and compared to the publishers' suggested usage according to grade level. Results showed that although formulas…
