Science curriculum standards were mapped onto various texts (literacy readers, trade books, online articles). Statistical analyses highlighted the inconsistencies among readability formulae for Grades 2-6 levels of the standards. There was a lack of correlation among the readability measures, and also when comparing different text sources. Online…

In this study, multiple thematically based and quantitative analysis procedures were utilized to explore the effectiveness of Turkish chemistry and science textbooks in terms of their reflection of reform. The themes gender equity, questioning level, science vocabulary load, and readability level provided the conceptual framework for the analyses.…

One of the key requirements of the Common Core State Standards for Reading is that all students must be able to comprehend texts of steadily increasing complexity as they progress through school. By the time they complete the core, students must be able to read and comprehend independently and proficiently the kinds of complex texts commonly found…

Readability formulas typically yield results stated as a number or grade equivalent. However, results of one formula may not be compared to another because formulas use different criteria to measure readability. A description of eight popular formulas illustrate this point. Suggests that other factors be considered when selecting reading…

Aspects of textbooks' readability are discussed and some recommendations are made. The results of applying three readability tests to 13 current textbooks are presented. (Author/BB)

Describes how to use a readability graph to determine the reading level of Biology textbooks. (MA)

Discusses reading levels of books in the sciences, and explains the use of the Readability Graph. Also reported are reading levels of selected high school physics texts. (GA)

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…

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…

Reviews using the cloze procedure for evaluating the readability of science textbooks. (SL)

Evaluated and compared 12 science textbooks with respect to their readability levels and agreement with the intended reader level. Four of the books were determined to be unsatisfactory for their intended grade levels. (20 references) (MDH)

Reports on an analysis of seven tests in use for CSE Human Biology to determine the technical vocabulary to which pupils are exposed. Lists the frequency of occurrence of every term, outlines the scheme used for classifying terms, and presents a selected vocabulary of terms considered to be the most popular. (GS)

Discusses categories for science textbook analysis under the headings of: Readability, Content, Presentation of Material, Mathematical Demands, Appearance, Quality of Illustrations, and Teacher Aids.
