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 Fry Readability Formula was employed to determine the reading grade levels of the eight most popular college U.S. history survey textbooks and the ten most popular Western civilization textbooks. It was discovered that the Fry readability technique could not produce consistently close findings on any single college history textbook. Indeed,…

Features are discussed that are critical to the comprehension of texts and that readability formulas cannot handle. The critique and alternative analyses are confined to public and institutional documents and are based on research in cognitive psychology and psycholinguistics. Two types of comprehensibility complications are examined, those…

The manual is intended to help writers or adapters of instructional materials for deaf students. The first section examines difficulties in providing suitable reading material for deaf students. The problems in evaluating deaf students' reading levels are examined. Writers are cautioned to pay particular attention to syntax, vocabulary, and…

A formula for assessing style is described and applied to compositions written by adult students of English as a second language. Style is defined as the total effect of what is done by a writer in the composing process, including choice of words, organization, and sentence and paragraph strategies. Earlier attempts to quantify style are reviewed.…

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 purpose of this study was to determine whether three procedures-- the cloze, maze, and intact cloze--were reliable and valid measures of readability. One hundred and eighty one sophomores were involved in the study. A passage, An Industrial Giant: Standard Oil Company, from the U.S. history textbook "The People Make a Nation"…

In the past 30 or 40 years there has been much discussion about what factors contribute to readability in texts. In an attempt to characterize factors not measurable by current objective readability formulas, four texts that were adapted for younger readers were compared with their originals to see what kinds of changes adaptors had made and to…

The purpose of the study was to determine the readability level and the level of involvement for selected science textbooks for grades 7-10. A review of related literature concerning readability scales and the Romey Index is included. Thirty secondary science texts were evaluated using the Fry Readability Graph and Romey's Involvement Index. The…

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…

Reports a study of three readability formulas--Dale-Chall, Fry, and Harris-Jacobson--which were used to analyze five current sixth-grade reading textbooks. (JM)

Lists the dangers of readability formulas and concludes that while they may be a necessary evil, they should not be used as the underlying structure of a reading program. (FL)

Argues that, while computers make the computation of readability formulas easy, teachers should not forget the need to apply judgment and common sense to the results. Discusses RIXRATE, a computerized version of the Rix index and compares its performance to that of the Rauding Scale. (FL)

Describes a computer formula which measures readability according to how well high school seniors comprehend reading passages. (RB)

This book is a guide to the evaluation and development of textbooks that focuses on the research on which they are based to the writing of the text. It also explores research into textbook effectiveness and provides an overview of the research in the field. The chapters are: (1) "Respondents' Opinions"; (2) "Evaluation of Textbooks by…
