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 booklet describes and discusses a method for determining the readability level of prose passages in reading materials for children. The method discussed in the booklet assigns a value to each noun in selected passages on the basis of its frequency level on standard word-frequency charts, correlated in a number of studies with independent…

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…

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…

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

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.…

A new approach to measuring readability is proposed based on the analysis of texts as causally connected chains of actions, physical states, and mental states. Using the inference load formula reflecting the difficulty readers have in inferring causal connections, the difficulty of texts can be adjusted for readers differing in skill or knowledge.…

Examines the variables experienced teachers of deaf children use to make decisions about the difficulty of a text for use by their students and how effective teacher judgment actually is in determining text difficulty. (EKN)

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…

Investigates readability levels of correspondence sent out by Gulf Coast area business offices. Finds that a large majority of the correspondence sent out from the offices under study is written at too high a reading level. Finds also that the greatest problem lies in syllable intensity--the use of "big" words where everyday words would have…

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…

Developmental differences in summaries of expository texts were examined for fourth and sixth grade students in two experiments. Experiment 1 used texts that had a description content structure whereas Experiment 2 texts had a thesis/evidence content structure. Manipulation of the presence or absence of the topic sentence allowed the examination…
