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)

Examines the relationship of readability to usage of main idea clues in introductory texts in sociology and in English composition texts. Concludes that use of main idea clues provides a useful supplement to readability formulas in evaluating college textbooks. (SR)

Validates the college-level designation of the Fry Graph using comparative validity data. (AEA)

Provides guidelines for analyzing and evaluating textbooks based on their comprehensibility rather than their readability. (MKM)

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)

"Lasbarhetsindex" ("Lix") is a readability formula developed in Sweden that holds promise for assessing text difficulty in other languages, including English. So far three separate studies have been conducted to test Lix with French and English texts, with German and English texts, and with Greek and English texts. In all three…

A method proposed by McCuaig and Hutchings to assess the internal readability variation of books using the Fry readability formula was empirically tested in an analysis of six elementary basal and ten secondary remedial readers. Each book was treated as a series of consecutive 100-word samples. Means and standard deviations were computed for both…

Describes the Luiten, Ames, Bradley Readability Variation Method for estimating the variation within a text. Concludes that it is practical and relatively accurate. (HOD)

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.…

Examines the practical side of readablility in the United Kingdom as well as some theoretical considerations focused on research on text difficulty, microcomputer prediction of difficulty, validity of cloze procedure, and the effect when students rewrite textbook prose. (HOD)

It has been customary to simplify texts to increase their readability for young readers. Recent studies suggest that it is the predictability of texts that is the key to their readability and that simplification may actually create problems for the reader. (RBW)

Fry's Readability Graph was used to determine the readability levels of the 1981 Scott, Foresman and Co. basal textbook series for grades one through six. The readability levels were then compared to those established for the 1978 edition. In the 1981 edition, all stories were handscored. Poems, skill lessons, and plays were not examined in order…

The revised Spache Readability Formula and the Fry Readability Formula were applied to 20 selected reading materials designed for adolescents reading at second grade level. Three samples from each text were examined. The results using the Spache formula corresponded to the publisher's stated readability levels, with no significant variability…

Designed to appeal to students who want a short but up-to-date overview, researchers who are interested in a critical appraisal, and consumers who would like to know what leaders in the field think, this collection of articles highlights the changes that have occurred in readability research from the past to the present and makes predictions about…

After reviewing criticisms of the exclusive use of readability formulas to evaluate text difficulty and describing successful efforts to broaden the traditional readability formula approach, this report presents a 20 item checklist for determining text comprehensibility based on four criteria: (1) specific objectives or outcomes expected from the…
