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…

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)

Reported is a study designed to determine whether reading grade level (RGL) assessment techniques used for elementary and secondary education textbooks would discriminate among plant and soil science textbooks. The study was to select the RGL indices suited to quantify the readability of these sources, and to identify the factors affecting…

Reports on a study which attempted to determine the reading level of 70 filmstrips with captions that form logical sequences. Results indicate that the classroom teacher might want to use readability formulae in planning the use of filmstrips. (Author/SA)
