Readability formulas can be useful tools in accomplishing their primary purpose--to give very general estimates of difficulty. Unfortunately, there has been a great deal of misunderstanding regarding their use, which has resulted in misuse and abuse. The formulas were designed to be applied post hoc to existing materials. They were not intended to…

Drawn from a symposium presented at the 1979 National Reading Conference, the four papers in this collection describe a notion of conceptual readability, an approach contrasting with traditional readability computations (number of words per sentence and degree of familiarity of individual words) and focusing on the concepts communicated by the…

The readability level of passages from three subtests of the Iowa Tests of Educational Development (ITED), Forms X-6 and Y-6, were compared with the readability level of passages selected from the Des Moines Resister, Reader's Digest, Time, Newsweek, Saturday Review, and 18 high school textbooks from the fields of social studies, science, and…

A study was conducted to test whether quantitative feedback would help students write with the stylistic simplicity appropriate to their audience and purpose without sacrificing other elements of good writing. Two business and technical writing classes received identical reading assignments, classroom activities, and writing assignments; but one…

On the assumption that the verbal complexity of written examination materials used to select personnel for a job should be similar to the verbal complexity of materials that must be read and understood on the job, the Flesch Reading Ease Index was applied to samples of the reading materials required for successful entry-level job performance in…

A study was designed to validate the Navy Readability Indices (NRIs) in an individualized instructional system using the criteria of comprehension and learning time. Two hundred Navy enlisted personnel enrolled in a computer-managed technical training course were tested for both comprehension and learning-time-to-criterion on four programmed…

Discusses the difficulty of determining the readability of textual material. (MKM)

Investigates the readability level of written materials (such as notices or newsletters) sent by six all-day kindergartens/child-parent centers to parents of disadvantaged children. Found that the readability of the materials ranged from sixth grade to higher than college level, and that the mean level was midtenth grade. (ARH)

Parts 1 and 2 (SE 524 424 and 527 089) described Flesch readability for determining a text's reading level and results of applying the test to astronomy/physics textbooks. This part presents results for a new sample of texts, including calculus-level texts. A comparison with high school physics texts is provided. (JM)

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)

Many students from elementary school through college encounter difficulty understanding their science textbooks, regardless of whether they have language disorders. This article discusses some of the particular difficulties associated with science text comprehension and possible remedies for facilitating and enhancing comprehension of challenging…

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…

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…

Designed to alert adult basic education teachers to the factors of readability and to suggest ways that some readability problems can be alleviated, this resource unit discusses the problems posed by readability formulas and suggests that teachers must both press for more readable adult texts and question intelligently the products of publishers…
