In this investigation, we examine the contribution of intrinsic content density (ICD) to measures of expository text processing. In Studies 1 and 2, the factor structure of select text density metrics was examined and refined using two text samples (Ns = 150) randomly selected from an expository text corpus. Scores on the ICD measure based on the…

Educators often inquire about the readability of books and other documents used in the classroom, with the idea that readability supports students' reading comprehension and growth. Documents used in classrooms tend to be language-based, so readability metrics have long focused on the complexity of language. However, such metrics are unsuitable…

The development and evaluation of valid assessments of scientific reasoning are an integral part of research in science education. In the present study, we used the linear logistic test model (LLTM) to analyze how item features related to text complexity and the presence of visual representations influence the overall item difficulty of an…

In some cases difficult-to-read learning materials lead to better performance than easy to-read materials. This phenomenon is called the disfluency effect and is attributed to a subjective feeling of task difficulty resulting in a deeper learning approach. In two studies (n[subscript 1] = 67, n[subscript 2] = 73) we investigated the impact of…

When faced with excessive detail in an online environment, typical users have difficulty processing all the elements of representation. This in turn creates cognitive overload, which narrows the user's focus to a few select items. In the context of e-learning, we translated this aspect as the learner's demand for a system that facilitates the…

Largely due to technological advances, methods for analyzing readability have increased significantly in recent years. While past researchers designed hundreds of formulas to estimate the difficulty of texts for readers, controversy has surrounded their use for decades, with criticism stemming largely from their application in creating new texts…

The present findings imply that a readability formula is not an effective writing production criterion, even when the writer does not deliberately write to the formula. Comprehensibility of text might be better controlled through the proper use of the transformer concept (MacDonald-Ross and Waller). (Author/PN)

Focusing on what authors can do to facilitate learning from content area textbooks, this report labels authors as "considerate," providing text that readers can understand with a minimum of cognitive effort, or as "inconsiderate," creating text that requires a conscientious, highly skilled effort if readers are to comprehend…

Presents the results of a study of the recall performances of developing young readers compared across the three language reception modes of listening, oral reading, and silent reading. The effects of the difficulty of the reading material and of sex differences are discussed. The texts used are appended. (Author/JL)

An 11 page chapter from a sixth grade social studies text was used in a study assessing the complexities of comprehending social studies materials and the sensitivity of prospective and experienced teachers to these complexities. A sentence-by-sentence analysis of the thinking operations required for mastery of the material showed that numerous…
