Readability estimates are usually based on measures of word difficulty and measures of sentence difficulty. Word difficulty is measured in two ways: by the structural size and complexity of words or by reference to phonomena of language use, such as word-list frequency or the regularity of spelling patterns. Sentence difficulty is measured only in…

The purpose of this study was to determine whether: (1) a new basal reading series (N Series) contained a larger variety of sentence patterns in beginning reading materials than a traditional reading series (T Series); (2) the variety of language patterns was systematically increased in beginning reading materials within either series; (3) the T…

An investigation of the relationships between form and comprehension of written materials by eleventh grade students is reported in this paper. Students were asked to manipulate two variables of spacing and punctuation in a consistently administered and marked exercise. Students also completed a comprehension test on the exercise they had just…

Reviews research using sentence length as a factor in predicting readability and discusses the possibility of sentence complexity as a more accurate variable. (TO)

IN AN EFFORT TO DEVELOP ACCURATE FORMULAS FOR PREDICTING AND CONTROLLING THE READABILITY OF LANGUAGE, FIVE BASIC PROBLEMS WERE STUDIED--(1) THE VARIOUS FEATURES OF WRITING STYLE AS LINEARLY RELATED TO COMPREHENSION DIFFICULTIES, (2) THE CHANGE OF STRENGTHS OF RELATIONSHIPS AS A FUNCTION OF READING ABILITY, (3) READABILITY PREDICTION MADE UPON…
