Textbooks remain as major learning aids in all levels of education worldwide. Thus, textbooks must constantly be subjected to critical analysis in order to establish their curricular usefulness. This paper analyzed four commercial science textbooks designed for third grade Filipino learners. The four textbooks were analyzed according to…

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…

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)

This article describes readability assessment methods used in science education, summarizes reported readability estimates of science textbooks, and recommends strategies for reducing the readability load of such materials. (JMF)

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…

Some factors that should be considered when science teachers produce materials for their students are presented. Readability and the key aspects of language (vocabulary, sentence structure, textbook or examination style, and organization and presentation) are discussed. Directions and the graph needed for estimating the reading level of materials…

Parts 1 and 2 (SE 524 424 and 527 089) described Flesch readability for determining a text's reading level and results of applying the test to astronomy/physics textbooks. This part presents results for a new sample of texts, including calculus-level texts. A comparison with high school physics texts is provided. (JM)

Discusses findings from a questionnaire survey of 622 biology teachers on: (1) how accurately they can judge readability of instructional materials; (2) what factors they consider when judging readability levels; and (3) if they considered differences in students' reading ability when selecting reading materials for them to use.
