The passage comprehensibility of three diagnostic reading tests--the Stanford Diagnostic Reading Test, the Spache Diagnostic Reading Scales, and the Durrell Analysis of Reading Difficulty--was evaluated using the following text variables: content familiarity, vocabulary, the number of idea units in the text, the number of text-based inferences…

Fry's Readability Graph was used to determine the readability levels of the 1981 Scott, Foresman and Co. basal textbook series for grades one through six. The readability levels were then compared to those established for the 1978 edition. In the 1981 edition, all stories were handscored. Poems, skill lessons, and plays were not examined in order…

A study investigated the readability of current laws for Canadian francophones and anglophones. The 63 subjects were asked to read a variety of brief legal texts available in parallel styles in both languages and to answer questions about the texts' content. Subjects were also surveyed about their preference for a formal or vulgarized style of…

In spite of their limitations, readability formulas can help teachers determine whether there are differences between students' reading abilities and the difficulty levels of the textbooks they are required to use. A study was conducted to assess the reading levels of students and the readability levels of textbooks at five selected junior…

Readability formulas were applied to the drivers' manuals of each of the 50 United States and Puerto Rico to determine whether the manuals were appropriate materials for motivating reluctant or low achieving adolescent readers. Four 100-word samples were chosen from each manual, according to four themes common to each manual and of particular…

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)
