What is meant by text complexity is a measurement of how challenging a particular text is to read. There are a myriad of different ways of explaining what makes text challenging to read, from the sophistication of the vocabulary employed to the length of its sentences to even measurements of how the text as a whole coheres. Research shows that no…

Background: Readability tests are indicators that measure how easy a document can be read and understood. Simple, but very often ignored, readability statistics cannot only provide information about the level of difficulty of the readability of particular documents but also can increase an evaluator's credibility. Purpose: The purpose of this…

Describes a study that analyzed the readability of documentation designed for physicians searching the Physician's Data Query cancer database, using the readability formulas in AT&T's Writer's Workbench software package. The results of the analysis are discussed and suggestions for future research are made. (20 references) (CLB)

Provides a 17-item annotated bibliography addressing issues of measures of readability for languages other than English, the mismatch between student reading ability and text readability, and promising new approaches to readability. (MG)

A survey of the current research on readability formulas is presented in this paper, which distinguishes this research from research on the more general questions that surround formulas: What features of a text, particularly the language it is written in, make the text easy or difficult to read? and, What will predict that readers with particular…

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)

This document discusses the measurement of reading ability and the readability of books by application of the Lexile framework. It begins by stating the importance of uniform measures. It then discusses the history of reading ability testing, based on the assumption that no researcher has been able to measure more than one kind of reading ability.…

Presents a readability formula suitable for passages from 40 to 99 words (provided they contain at least 3 sentences). (RS)

Discusses methods of textual documentation that can be used for software documentation. Highlights include measurement of text comprehensibility; methods for the measurement of documentation quality, including readability and the Cloze Procedure; tools for the measurement of text readability; and the development of the Reading Measurability…

Research on schema theory and the psycholinguistic perspectives of reading suggest that the measures of readability currently used on second language tests be reconsidered. Because foreign language readers, especially in the early stages of language learning, often do not have the necessary schema or background knowledge, teachers should include…

Discusses the importance of determining the reading difficulty of vocational materials. Explains how to determine the readability of materials, using the FORECAST Readability Formula, presenting guidelines on how to select sample passages, apply the Formula, and analyze the data. An example showing the Formula's use is provided. (LRA)

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 failure of readability formulas can be attributed to three weaknesses in the formulas. First, they ignore or violate current knowledge about the reading process. Most formulas affect only sentence length and word difficulty while ignoring factors that influence text comprehensibility, such as cohesion, the number of inferences required, the…

The present findings imply that a readability formula is not an effective writing production criterion, even when the writer does not deliberately write to the formula. Comprehensibility of text might be better controlled through the proper use of the transformer concept (MacDonald-Ross and Waller). (Author/PN)

The Flesch readability index yields meaningful information about the responses of readers to texts. Because the formula is so simple, a group of English teachers wrote a program in BASIC that would count some obvious surface features of a text and calculate Flesch scores. Among the programing problems encountered were counting words (taking into…
