Norms for Air Force technical training materials were developed for seven previously developed structure-of-intellect and seven psycholinguistically oriented variables which have been used to assess the readability/comprehensibility of textual materials. Separate norms are presented for Air Force study guides, manuals, career development course…

Writing, editing, and printing texts for schools has been the accepted role of publishers, while text researchers have concentrated on typography, content, and readability. The hundreds of readability formulas now available make readability the most sophisticated of these three areas. Research in reading comprehension suggests that publishers…

Two studies investigated the relationships between readability, prior knowledge, and interest in the material being read. In the first study, 169 college freshmen read cloze passages of materials from the Nelson-Denny Reading Tests, then one week later read the whole passages and completed the related multiple choice questions. A control group…

A Missouri study was conducted to investigate the reading abilities of the average vocational technical student to determine if this reading ability was commensurate with the material the student was assigned to read, and to compare the effectiveness of the reading ability to success in completing a vocational course of study. In order to secure…

Describes an adjustment factor which makes readability formulas more accurate. (RB)

Describes a revised readability formula for Vietnamese that differentiates between Vietnamese and Sino-Vietnamese compound words and discusses its validity and reliability. (HOD)

It has been customary to simplify texts to increase their readability for young readers. Recent studies suggest that it is the predictability of texts that is the key to their readability and that simplification may actually create problems for the reader. (RBW)

Describes research conducted in France on text readability and suggests that readability formulas give high scores to redundant texts that have no great interest and penalize texts with original information. Argues that a coefficient should be incorporated into readability formulas that reflects the nature of the text. (MKM)

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…

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…

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…

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…

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…

Discusses findings from a questionnaire survey of 622 biology teachers on: (1) how accurately they can judge readability of instructional materials; (2) what factors they consider when judging readability levels; and (3) if they considered differences in students' reading ability when selecting reading materials for them to use.
