Argues against the implicit use of readability formulas as guides to writing graded texts and urges experimental research to define the real factors constituting readability. (AEA)

This article describes readability assessment methods used in science education, summarizes reported readability estimates of science textbooks, and recommends strategies for reducing the readability load of such materials. (JMF)

The development of a readability formula designed to determine the readability level of German instructional materials at the elementary level is discussed in this paper. The readability formula which was developed is called the German Readability Graph and is similar to the Fry Readability Graph. Syllables and number of sentences are counted per…

A new approach to measuring readability is proposed based on the analysis of texts as causally connected chains of actions, physical states, and mental states. Using the inference load formula reflecting the difficulty readers have in inferring causal connections, the difficulty of texts can be adjusted for readers differing in skill or knowledge.…

The issue of readability vs academic standards in college textbooks is addressed. Problems in balancing both needs and other problems involving textbooks and the publishing industry, including textbook resales and routine revisions of texts, are discussed. (JMD)

A study was conducted to evaluate the level of difficulty of textbooks (French and Sciences) written in French for use with sixth grade students. A cloze test was administered to a sample of sixth grade students in two francophone districts in the province of New Brunswick, Canada, and the Henry readability formula was applied to the same texts.…

Suggestions are presented in this paper to aid in the effective selection of instructional materials appropriate to the reading levels of the students who will use them. Formulas designed to predict the readability of material are discussed. The cloze procedure, which attempts to measure, for individuals, the difficulty of text, is recommended for…

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…

Shows how a number of readability measures developed in English were applied to a textbook written in Hindi. Emphasizes that the more recent approaches to readability that focus on syntax, conceptual difficulty, and organization are a teacher's best help in selecting materials for students. (SR)

A study examined the relation between formula ratings and student perception of both readability and interest in developmental reading/study skills and intermediate composition texts. Subjects, 200 composition students and 96 study skills students, responded to the statements "this text was easy to read" and "the text chapters were…

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…

Reports findings of a study that examined the extent to which the variability observed in reading levels of common junior high textbooks was also present in four popular high school social studies texts. (FL)

Writing, editing, and printing texts for schools has been the accepted role of publishers, while text researchers have concentrated on typography, content, and readability. The hundreds of readability formulas now available make readability the most sophisticated of these three areas. Research in reading comprehension suggests that publishers…

Reports the means, standard deviations, and relevant statistics on an examination of the readability of 24 contemporary textbooks that employ a hybrid approach to the basic speech communication course. Discusses some strategies for developing reading skills. (KEH)

The learning difficulties described by students in statistics courses continue to engage researchers from several disciplines. One source of difficulty for graduate students in educational statistics courses is the reading difficulty of the textbook. Instructors making decisions about a textbook typically have little information about the reading…
