The increase in the cost of college textbooks together with the proliferation of digital content and devices has inspired the development of open textbooks, open educational resources that are free, openly licensed, and often peer-reviewed. Although several published studies have investigated the impact of open textbook adoption on educational…

The widely adopted Common Core State Standards (CCSS) call for raising the level of text complexity in textbooks and reading materials used by students across all grade levels in the United States; the authors of the English Language Arts component of the CCSS build their case for higher complexity in part upon a research base they say shows a…

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

McLaughlin's Smog Index was compared to the Dale-Chall formula for the determination of reading levels of 48 textbooks in business and distributive education. A Modified Smog Index proved a valid substitute for the Dale-Chall formula when used to evaluate the reading levels of business and distributive education narrative. (Author/CT)

Determines from empirical information on the application of four readability formulas to a group of widely used college economics textbooks that there is no consistency in the absolute reading levels or the rank orderings of these books. (AEA)

Discussion of the notion of readability focuses on predicting readability with computerized readability formulas. Semantic and syntactic factors are discussed, the development of readability formulas is described, and five commercially available computer readability formulas are reviewed, including the Readability Estimator, Readability Formulas,…

Noting that readability formulas are strictly text-based and therefore do not reflect the interactive nature of the reading process, this paper argues that many of the instructional material evaluations for which such formulas are used are inappropriate and offers more reader-based alternatives to the use of formulas. The first half of the paper…

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)

A study examined basal readers and trade books in terms of reading ease as estimated by readability formulas and the incidence of figurative language. Based on an earlier study, the study had three major goals: to (1) assess and compare two reading series ("A" and "B") at each of two grade levels; (2) assess and compare…

The reading achievement test scores of 239 low-income, southern, urban black students in grades three through eight were compared with their ability to comprehend the social studies books used in their classrooms. Achievement scores were obtained from the reading subtests of the Stanford Achievement Tests. A cloze passage was developed based on…
