How can we identify authentic reading material that matches the learner's proficiency and fosters their language development? Traditionally, this involves assigning a one-dimensional label to the text that identifies the grade or proficiency level of the learners that the text is intended for. Such an approach is inadequate given that both the…

To better understand dimensions of text complexity and their effect on the comprehension of adolescents, 103 high school seniors were randomly assigned to 4 groups. Each group read versions of the same 2 informational passages and answered comprehension test items targeting factual recall and inferences of causal content. Group A passages had a…

What is meant by text complexity is a measurement of how challenging a particular text is to read. There are a myriad of different ways of explaining what makes text challenging to read, from the sophistication of the vocabulary employed to the length of its sentences to even measurements of how the text as a whole coheres. Research shows that no…

Over the past decade in the United States, levelled texts, or "little books" with finely graduated levelling of text difficulty, have regained their status as a literacy staple for beginning readers. Despite their resurgence, questions remain regarding the reliability and quality of these books. In this study, we conducted a detailed…

The history of the evaluation of non-English written materials through the use of various mathematical formulae is reviewed. This process began in 1939 with Tharp's work in French, and has continued until the present. Formulas have been developed for Spanish, Russian, German, Hebrew, Chinese, and Vietnamese. In Europe, modifications of the Flesch…

This extensive review of research on the development of print materials covers text readability, structure of the prose, and organizational and format features of the text. Practical guidelines for developing textual materials that can be supported by empirical research are also presented. Conclusions are then drawn from the literature, and areas…

The purpose of this book is to introduce the research on readability, defined here as reading ease. The first part of the book covers how people read. A series of national literacy surveys show that the average person in the U.S. and most other countries are adults of limited reading skills. For example, the average adult in the U.S. reads at the…

This paper describes a study designed to find out whether children's reading would be affected by line spacing that is wider or narrower than the commonly used default values. The realistic, high quality test material was set using a range of four different line spacing values, and twenty-four children in Years 1 and 2 (between five and seven…

This empirically-based model depicts the interactive, constructivist process of reading and three classes of variables that influence reading. Teacher variables include presentation, instructional intervention, instructional climate, and behavior management. Text variables include text language, relevance, organization, story structures, and…

A readability study for the Albuquerque Technical-Vocational Institute (T-VI) was undertaken to provide information regarding the reading ability required to complete training and to function in entry-level jobs. Readability formulas were applied to materials used in training and on the job. In addition, students were tested for level of reading,…
