Text complexity has received increased attention due to the CCSS, which call for students to comprehend increasingly more complex texts as they progress through grades. Quantitative text complexity (or readability) indices are based on text attributes (e.g., sentence lengths, and lexical, syntactic, & semantic difficulty), quantified by…

In 2012 the Leyte Normal University developed a computer software--modelled after the Spache Readability Formula (1953) made for English--made to help rank texts that can is used by teachers or research groups on selecting appropriate reading materials to support the DepEd's MTB-MLE program in Region VIII, in the Philippines. However,…

Standards for literacy in the twenty-first century raise the bar on the complexity of texts and the tasks for which they are used. The strengths and limitations of contemporary approaches to text complexity are discussed with respect to major points raised in the six articles in this special issue. In addition, four features of text that are of…

One problem with readability formulas is that they are generally calculated on factors at the sentence and subsentence level. However, the representation of text through information structures is equally important. The complexity of information structures and their realizations will affect reading difficulty and should be incorporated into…

"Writeability" is concerned with helping writers and editors produce materials on easier readability levels. A major input of most readability formulas is vocabulary difficulty. One way to increase readability is to use simple vocabulary or shorter words since word frequency studies show that more common words are shorter. The other…

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…

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.

The possibility of changing the prosaic style of college level science textbooks to increase readability was investigated. Conclusions suggest that the readability of college textbook prose is not significantly affected by the stylistic factors employed in most readability formulas. (CJ)

Argues that readability formulas accurately predict how easily a passage will be understood by considering sentence length and word difficulty. Claims that the misuse of readability formulas as writing guides is responsible for much of the criticism. Challenges the critics to come up with something better. (RS)

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

It is argued that informed judgments by a thoughtful teacher may have advantages over the application of a readability formula in assessing the linguistic difficulty of a text. Examples are given. (KC)

Describes a revised readability formula for Vietnamese that differentiates between Vietnamese and Sino-Vietnamese compound words and discusses its validity and reliability. (HOD)

This working paper summarizes the results of an expert panel review of the Lexile Framework (LF). The review was conducted by five panel members through readings, the preparation of brief individual reports, and participation in a meeting held on April 26, 2001 in Washington, D.C. The list of panel members and invited observers, along with brief…

Discusses elements other than reading level that can affect ease of understanding vocational materials. Groups these elements into four major areas: (1) vocabulary, (2) sentence structure, (3) organization (the way sentences are arranged into paragraphs), and (4) relevance (the way the author relates the topic to the reader's experience). (LRA)

A study examined whether (1) there are untested indices of difficulty that can be used to enhance the accuracy of readability formulas, (2) the same readability formula can be used to assess the readability of text for mature and immature readers and for good and poor readers, and (3) some one model of the reading process or some synthesis of…
