"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…

There is a need for basic readability research and for an easily applied and accurate new readability formula. Two steps taken toward the development of such a formula are the revision of a vocabulary list for primary grades and the combination of reading exercises given at different grade levels into a single scale of ascending difficulty. Much…

Readability estimates are usually based on measures of word difficulty and measures of sentence difficulty. Word difficulty is measured in two ways: by the structural size and complexity of words or by reference to phonomena of language use, such as word-list frequency or the regularity of spelling patterns. Sentence difficulty is measured only in…

One of the major objectives of this study was to obtain an estimate of the reading skill level an individual would need in order to be able to read and understand the training and job materials in his Air Force career ladder. A methodology developed by Mockovak (1974) for comparing training and job reading requirements was used to calculate the…

This review of findings in the field of readability research discusses the differences in meaning between readability and legibility, examines the origins and developments of readability formulas for children's and adult materials, and describes several of the best-known formulas for English-language materials.

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

Offers a case study of how one teacher used readability formulas to select the most appropriate materials for her students. Presents 10 suggestions that the teacher followed to avoid being tyrannized by the formulas. (FL)

Proposes that readability formulas cannot predict text difficulty. Presents results of an experiment designed to demonstrate that "text difficulty" is determined by individual differences (perception) and not by the objective qualities of a text. (NH)

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.…

A previous report defined a series of 14 novel measures for determining the comprehensibility of English text on the basis of current psycholinguistic and Structure-of-Intellect concepts. That report not only suggested the potential usefulness of the measures but also conjectured about the feasibility of automating the calculation of these…

The papers included in this collection represent as closely as possible the content and organization of the oral presentations delivered at a March 1980 conference on the use of readability formulas. The papers discuss the following topics: (1) an introduction to the conference, with general remarks on the uses and criticism of readability…

In a response to the Mikulecky and Diehl examination of work-related literacy, this paper points out the need for data based on ethnographic approaches to research and more realistic assessments of text difficulty. Also suggested are questions to which future research might respond: How much of functional literacy is really functional competency?…

This literature review documents the state-of-the-art of readability assessment and indicates directions for future research in readability measurement. The period since 1953 is emphasized, although there is some consideration of earlier work. Primary emphasis within the review is based on readability measurement; however, a final section is…

Raises doubts about the validity of readability formulas. (RB)
