A recent Educational Testing Services report (2016) found that international graduate students with a TOEFL score of 80--the minimum average TOEFL score for graduate admission in the United States--usually possess reading subscores of 20, equating to a 12th-grade reading comprehension level. However, one public flagship university's international…

The research genre has specific communicative purposes which require students to understand the tone, generic and disciplinary conventions. The present study explored the potential of thematic progression (TP) to contribute to research argument readability. TP concerns how clauses encode information and how that information is carried forward.…

According to the RAND model framework, reading comprehension test performance is influenced by readers' reading skills or reader characteristics, test properties, and their interactions. However, little empirical research has systematically compared the impacts of reader characteristics, test properties, and reader-test interactions across…

In the late 1980s Batia Laufer worked with teachers who believed that to understand a text it was enough to understand 80% of the text's word tokens. In response, Laufer set out to calculate the minimal text coverage, i.e., percentage of running words in a text the reader should understand to comprehend it reasonably well. In 1992, she explored…

Identifies and describes major factors interacting with readability measures in 36 experimental studies analyzing the validity of such measures. (RB)

Discusses the accuracy of the Fog Index and the SMOG grade (two readability formulas) as predicators of readability. (MAI)

Found that standard readability indexes by themselves are not useful in measuring readability and comprehensibility of income tax material. Also casts doubt on the use of only readability indexes to measure insurance, labor, and real estate contracts. (PD)

Provides guidelines for analyzing and evaluating textbooks based on their comprehensibility rather than their readability. (MKM)

A survey of the current research on readability formulas is presented in this paper, which distinguishes this research from research on the more general questions that surround formulas: What features of a text, particularly the language it is written in, make the text easy or difficult to read? and, What will predict that readers with particular…

Although research on readability is still in its infancy, studies have been conducted concerning typographical features, semantic and pragmatic facets, linguistic factors, and orthographic dimensions. This paper discusses readability formulas, pointing out their limitations and listing 13 generalizations about them. The paper also outlines…

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)

Describes a computer formula which measures readability according to how well high school seniors comprehend reading passages. (RB)

This literature review documents the state-of-the-art of readability assessment and indicates directions for future research in readability measurement. The period since 1953 is emphasized, although there is some consideration of earlier work. Primary emphasis within the review is based on readability measurement; however, a final section is…

Raises doubts about the validity of readability formulas. (RB)
