Text complexity has received increased attention due to the CCSS, which call for students to comprehend increasingly more complex texts as they progress through grades. Quantitative text complexity (or readability) indices are based on text attributes (e.g., sentence lengths, and lexical, syntactic, & semantic difficulty), quantified by…

"Writeability" is concerned with helping writers and editors produce materials on easier readability levels. A major input of most readability formulas is vocabulary difficulty. One way to increase readability is to use simple vocabulary or shorter words since word frequency studies show that more common words are shorter. The other…

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…

In this study, a test of syntactic complexity was developed to be administered to adult beginning readers. The purpose of the test was to determine syntactic competence in the reading of these adults as compared with literate adults. The test was developed on the basis of a review of the literature related to acquisition of syntax, complexity of…

The original version of the "Helen Keller Story" and a linguistically more complex version of it were used to test the hypothesis that reading comprehension is affected by the complexity of linguistic structures. Complexity was measured by four readability measures, the mean number of words per T-unit, and the Schmidt-Kittrell Linguistic…

Thirty-two fourth grade students were divided into two equal-sized groups according to reading ability. Each student read and recalled four passages from fourth-grade texts. The passages were either an original version, a semantic simplification, a syntactic simplification, or a combined rewrite. One week later, each child read and recalled…

Scientific discourse is difficult to read because of its lexical, syntactic, semantic, and logical features. This paper discusses each of those features, giving special attention to syntax, and suggests ways in which discourse analysis can be used to teach content reading in sciences and to rewrite scientific text for instructional purposes. Some…

The purposes of this study were to identify the best predictor or predictors of paragraph comprehensibility and to attempt to interpret that predictor as a skill. Forty-two passages of differing readability (ranging from grade 2.5 to 10.0) were analyzed for within word, within sentence, and between sentence characteristics. The measures used for…

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…

A review of the literature and an examination of the state of the technology is presented in this discussion of text analysis with computers. The computer capabilities of several available text analysis programs are reviewed, including those that examine vocabulary, word strings, sentence and syntactic complexity, and readability. (AEA)

Fifty-six third graders were randomly assigned to two treatment groups, in a study of the relationship between clause structure and the readability of written texts. The treatment groups read sets of passages which were identical except for certain word-order modifications. The dependent variables were silent- and oral-reading comprehension, rate…

This study questions the developmental nature of the ability to understand syntactic structures. An exploration is made of the possibility of learning more about reading comprehension and readability by examining responses made to sentences described by transformational grammarians as structurally ambiguous. A group of fifth grade students were…

Both sentence length and sentence complexity of various kinds of newspaper prose were examined in a study to determine (1) ways newspaper prose differs from the prose of books native English speaking students chose to read and enjoy reading and (2) whether there are features of newspaper prose other than vocabulary and a lack of international news…

A study examined the effect of five types of sentence faults on the method of information processing, recall ability, confidence rating, and comprehensibility rating of college freshman English students. The control text consisted of five passages and the accompanying comprehension questions exactly as they appear on the multiple choice Georgia…
