The research genre has specific communicative purposes which require students to understand the tone, generic and disciplinary conventions. The present study explored the potential of thematic progression (TP) to contribute to research argument readability. TP concerns how clauses encode information and how that information is carried forward.…

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…

Early in the 20th century, educators began looking for scientific methods for matching texts with readers. Some of the best minds in education dedicated themselves to this task, including Edward L. Thorndike, William S. Gray, Ralph Tyler, Edgar Dale, Irving Lorge, and Jeanne S. Chall. The purpose of this book is to bring students of reading into…

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…

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…

The problems arising from treating word and sentence complexity as the direct causes of difficulty in comprehension are surveyed in this paper from the perspective of readability formulas. The basic choices and assumptions made in the development and use of readability formulas are discussed in relation to the larger question of text…

Investigates readability of different line lengths in advertising body copy, hypothesizing a normal curve with lower scores for shorter and longer lines, and scores above the mean for lines in the middle of the distribution. Finds support for lower scores for short lines and some evidence of two optimum line lengths rather than one. (SKC)

To develop a new model of the reading process, a longitudinal study investigated the importance of the concepts of cohesion and register (fiction or nonfiction) in the assessment of text readability. Subjects, 436 8-year-olds (Cohort A), 474 10-year-olds (Cohort B), and 445 13-year-olds (Cohort C) from 23 urban and rural British schools--most of…

This paper is concerned with the process of human reading as a high-level perceptual task. Drawing on insights from artificial-intelligence research--specifically, research in natural language processing and continuous speech understanding--the paper attempts to present a fairly concrete picture of the kinds of hypothesis formation and inference…

This article reviews research concerning the organizational, selective, and connective aspects of reading and then assesses the impact of constructivism on four reading-related issues in the United States: (1) readability of texts; (2) assessment of reading ability; (3) instruction in reading; and (4) conception of literacy. The article argues…

Explores factors that influence readability and a reader's ability to process information. (TO)

Provides an assessment of the linguistic variables which affect the way in which children comprehend verbal data when they read. (RB)

Forty adults served as subjects in a study of the comprehensibility of instructions conditioned by multicategory compounds, such as "If you are male, or both married and not employed, go to question 3." The stimulus materials were 96 sentence frames of the form, "If you are X, press (button) Y," in which "X" was…

Investigated within-sentence contextual constraints in a sentence-completion task completed by 408 students from grade 6. (AA)

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…
