Compares a "new" measure for assessing the level of abstraction of textual material with an old measure. Finds some similarity in their assessment of science texts, and finds that the earlier measure may be easier for the nonspecialist to use. Suggests a rule of thumb for practicing teachers. (SR)

Noting that readability formulas are strictly text-based and therefore do not reflect the interactive nature of the reading process, this paper argues that many of the instructional material evaluations for which such formulas are used are inappropriate and offers more reader-based alternatives to the use of formulas. The first half of the paper…

The Fry Readability Formula was employed to determine the reading grade levels of the eight most popular college U.S. history survey textbooks and the ten most popular Western civilization textbooks. It was discovered that the Fry readability technique could not produce consistently close findings on any single college history textbook. Indeed,…

The purpose of the study was to determine the readability level and the level of involvement for selected science textbooks for grades 7-10. A review of related literature concerning readability scales and the Romey Index is included. Thirty secondary science texts were evaluated using the Fry Readability Graph and Romey's Involvement Index. The…

Reported are results of a survey in which 13 series of secondary level geography textbooks were tested to determine readability. Findings indicate that there is little difference in the readability level of geography texts published for grade six and those published for the secondary level. References are included.

This book is a guide to the evaluation and development of textbooks that focuses on the research on which they are based to the writing of the text. It also explores research into textbook effectiveness and provides an overview of the research in the field. The chapters are: (1) "Respondents' Opinions"; (2) "Evaluation of Textbooks by…

Describes the "cloze" procedure for judging the readability of textbook prose and in particular how this procedure may be applied to written mathematical materials. (JP)

Presents an annotated list of textbooks in a number of vocational content areas and includes the readability level of each text. (TO)

This survey of 11 recently published biology textbooks includes an analysis of content, certain general characteristics, readability, and use of questions. Differences between these and earlier textbooks are noted. The reading difficulty of the new books is found to be less than for those covered in a previous survey. (Author/JN)

Fourteen high school physics textbooks are evaluated. Criteria include content, distribution/organization of content, level (appropriateness of presentation for high school students), readability, appearance, presentation of physics as a growing body of knowledge, awareness of social problems, and adequacy of materials for additional work by…

Concludes that the maze procedure tended to overestimate students' ability to cope with an unfamiliar text, while the cloze procedure appeared to be a reasonably accurate measure. (FL)

Calls for new textbooks to teach Russian literature. Complains of inappropriate wording for young people, officious and boring content, and a lack of humanistic themes in existing textbooks. Suggests that a text be compiled from among the best literary and critical articles to develop in students a love and understanding of literature. (DK)

Researchers examined whether there were differences in the way elementary history textbook and trade book passages were structured. Analyses of text structure in topic-similar passages from both types of books indicated trade books were more comprehensible than history textbooks by being better structured and more coherent. (SM)

Describes an approach, called "Questioning the Author," that is targeted toward getting young readers to engage with their textbooks--to really consider ideas deeply. Notes that the approach attempts to actualize the presence of an author, understand the author as a fallible transmitter of ideas, and transform author's ideas into readers' ideas.…
