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 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…

A number of reading specialists are finding themselves testifying in court or writing expert opinions for court cases in such diverse areas as civil rights, criminal law, contracts, warranties, and due process. The validity of readability formulas was tested in the case of David v. Heckler. Another case involved a group of Florida prisoners who…

A study was conducted with 782 elementary school students to determine whether the Homan-Hewitt Readability Formula could identify the readability of a single-sentence test item. Results indicate that a relationship exists between students' reading grade levels and responses to test items written at higher readability levels. (SLD)

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…

Proposes that prediction and production variables used together tap both text and reader factors and provide a much improved analysis of readability. Finds that this kind of analysis will lead to more specific kinds of pedagogical strategies for teaching writing. (MS)

Some factors that should be considered when science teachers produce materials for their students are presented. Readability and the key aspects of language (vocabulary, sentence structure, textbook or examination style, and organization and presentation) are discussed. Directions and the graph needed for estimating the reading level of materials…

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…

One of a series dealing with current issues affecting language arts instruction, this paper focuses on the conceptions and misconceptions of readability. The paper begins by noting that over the years, researchers in readability have had two major goals: to determine what makes written materials easy or difficult to read and comprehend, and to…

The purpose of this book is to introduce the research on readability, defined here as reading ease. The first part of the book covers how people read. A series of national literacy surveys show that the average person in the U.S. and most other countries are adults of limited reading skills. For example, the average adult in the U.S. reads at the…

Discusses the history of the development of the measurement of reading levels and current criticism of the use of reading levels. Also discusses the relationship between a teacher's effectiveness as a reading instructor and the teacher's understanding about the concept of reading levels. Includes suggestions for change and a list of references.…

Investigates reliability of two approaches for estimating text difficulty at the first-grade level: the Scale for Text Accessibility and Support and the Fountas/Pinnell system. Supports the predictive validity of the two rating scales with performance data. Suggests potential benchmarks for first-grade performance: 95% accuracy; 80 words per…

Provides step-by-step procedures for developing an index which uses the Gunning Fog technique to evaluate the level of reading difficulty of textbooks. Cites examples, illustrations, and several warnings in the discussion. (RT)
