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…

College students can read, but they often lack the prereading and postreading skills needed to help them think about and respond to what they read. A three-step plan can help students read and understand the text more fully. The first step entails using measures of fitness to determine: (1) the grade level of the text being considered and how it…

Four readability indices that focus on the ease of comprehension of printed material are applied to industrial education textbooks for senior high school students. Grade reading levels by subject areas for the four indices are presented in tables, charts, and text. Certain conclusions about the readability techniques studied are suggested. (MF)

Provides step-by-step procedures for developing an index which uses the Gunning Fog technique to evaluate the level of reading difficulty of textbooks. Cites examples, illustrations, and several warnings in the discussion. (RT)

The study reported in this paper was designed to describe the differences between the reading-difficulty levels of primary textbooks used in first-semester freshman general studies courses and the reading skills of the students enrolled in those courses, and to compare the Flesch Reading Ease Formula with the SMOG Grading Formula. Separate…

In this literature review, readability studies are classified under quantitative, qualitative and combined quantitative-qualitative readability…

The objectives of this study were to develop a method for scoring the level of abstraction (LOA) of science reading material and explore its relationship with other methods for assessing curriculum materials. LOA is defined as the ratio of the nonconcrete concepts to the total number of concepts in a written passage expressed as a percent.…

Two readability formulas were applied to two math and two reading series textbooks at the fourth, fifth, and sixth grade levels to see whether the publishers' suggested reading levels were accurate. Five samples were taken from each text and compared to the publishers' suggested usage according to grade level. Results showed that although formulas…

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…
