This paper considers whether the sources of linguistic complexity presented within texts targeted at 1st-grade readers have increased, decreased, or held steady over the 52-year period from 1962 to 2013. A collection of more than 450 texts is examined. All texts were selected from Grade 1 textbooks published by Scott Foresman during the targeted…

Argues that readability formulas accurately predict how easily a passage will be understood by considering sentence length and word difficulty. Claims that the misuse of readability formulas as writing guides is responsible for much of the criticism. Challenges the critics to come up with something better. (RS)

A word frequency study of two graded readers and an unsimplified text indicated that graded readers facilitated better foreign-language reading and vocabulary learning than did unsimplified texts. It was found that students needed to read several same-level texts to master vocabulary, and that vocabulary mastery was not necessary for successful…

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)

A study was conducted to determine the effects of sentence length, sentence structure, and word frequency on the readability of textbook prose. Specifically, the study assessed the extent to which the factors, taken alone or in combination, affected the readability of two 1,000-word college textbook passages when the content remained the same. Two…

Concludes that it is necessary to consider text frequency and standard frequency index and to discriminate technical words from technical support and nontechnical words to obtain a reliable indication of a science text's readability. (AEA)
