This report is a guide for the maintainer or developer of the computerized comprehensibility system (CCS), a system that uses techniques and results from artificial intelligence and cognitive psychology to critique the comprehensibility of a technical document. The purpose of this report is to allow the qualified programmer to rapidly understand…

This study asked participants to rate models of computer-generated text on the perceived ease with which it could be read and studied. These ratings were submitted to a Q-mode factor analysis to identify the underlying criteria used when the reader/perceiver formed a judgment related to the "study-ability" of the text model. Subjects…

A study examined the general structure of children's information books and their use of language. A corpus of over 110 information books was examined for (1) obligatory elements of the genre, (2) optional elements, (3) iterative or repeating elements, (4) elements with fixed orders of occurrence in relation to other elements, and (5) elements with…

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…

A formula for assessing style is described and applied to compositions written by adult students of English as a second language. Style is defined as the total effect of what is done by a writer in the composing process, including choice of words, organization, and sentence and paragraph strategies. Earlier attempts to quantify style are reviewed.…

A study was conducted to define the linguistic and discourse parameters of text difficulty from the point of view of both the reader and the text in order to redefine readability and to provide an operational way of explaining processing difficulties of the near-mature reader. Subjects were 14-year-old students in the United States and the United…

The purpose of this study was to determine whether three procedures-- the cloze, maze, and intact cloze--were reliable and valid measures of readability. One hundred and eighty one sophomores were involved in the study. A passage, An Industrial Giant: Standard Oil Company, from the U.S. history textbook "The People Make a Nation"…

Current textbooks on reading recommend six scoring systems to be used with cloze tests to find material of suitable difficulty for instruction. These six scoring systems, when applied to a single data source--300 cloze scores obtained from ninth grade students tested with ninth grade content materials--produced varied placements which at present…

Presenting an overview of the theoretical perspective underlying work on text analysis in progress at the Center for the Study of Reading (Champaign-Urbana, Illinois), this report emphasizes the work that group has undertaken on stories for children in grades one through five. The report discusses three factors, drawn from a theoretical model,…

Paul Hanna (1966), in his classic spelling study, developed frequency tables that described the relative frequency of the letters (graphemes) used to represent the major English sounds (phonemes). By restructuring the Hanna tables, a set of tables may be developed for estimating levels of reading difficulty based upon the relative frequency of the…

Samples of government publications, legal documents, newspapers, paperback novels, and instruction manuals were among the items used in a study to determine the degree to which the readability levels of materials used by adults reflect an awareness of and adjustment to the average reading ability of the adult population. The readability levels of…

Teachers can match content reading materials with student needs and abilities in a number of ways. If textbooks are the main or only source, teachers can group students according to textbook difficulty, conduct student surveys of specific topics in the textbook, and use the textbook as a sampler or starting point for more in-depth studies of…

College-adult reading research trends are discussed. The reading process; the influence of vision, perception, and personality; and program outcomes are noted as major trends of past studies, and a list of mistaken assumptions in these earlier studies is given. Present research shifts to the study of the role of both teacher and student…

The validity of Fry's Readability Graph for determining grade level readability scores was compared with the Spache Formula, the cloze technique, and oral reading in the case of seven primary-level books. Descriptions of these four indicated that to determine grade level, Fry's Readability Graph plots the total number of syllables with the total…

Ten easy-to-read books were examined for readability using Fry's Readability Graph and Betts' criteria for oral reading performance. Five first-grade and second-grade children read selected passages from each of the ten books. A correlation of 0.73 was obtained between rank orders according to readability graph scores and according to oral reading…
