Background knowledge is a strong predictor of reading comprehension, yet little is known about how different types of background knowledge affect comprehension. The study investigated the impacts of both domain and topic-specific background knowledge on students' ability to comprehend and learn from science texts. High school students (n = 3,650)…

In this mixed method study I evaluated the relationship between teachers' perceptions of text complexity and data of text complexity assessed by standard and non-standard measures in the disciplines of English Language Arts (ELA), science, and social studies. For the quantitative portion of this study, I evaluated and correlated the text…

Within this article, we introduce our conception of text accessibility. First, we synthesize recent research on informational text quality and present key attributes proven to contribute to comprehension of science texts beyond the readability formula. These features include (a) the concreteness of text, (b) the voice of the author, (c) coherent…

In 1979, a study was conducted at Palomar College (PC) to measure student reading levels; to determine textbook readability in humanities, science, and vocational education courses; and to make recommendations for adjusting the curriculum and/or screening procedures in order to facilitate increased student success in reading technical content-area…

This article presents a rationale for incorporating reading activities with science. It emphasizes that science investigations can provide a background for, and an interest in, reading among students. Three approaches for using science as a vehicle for reading are given: (1) the unit approach; (2) the tradebook, activity card approach; and (3) the…

The objectives of this study were to develop a method for scoring the level of abstraction (LOA) of science reading material and explore its relationship with other methods for assessing curriculum materials. LOA is defined as the ratio of the nonconcrete concepts to the total number of concepts in a written passage expressed as a percent.…

Reported is a study designed to determine whether reading grade level (RGL) assessment techniques used for elementary and secondary education textbooks would discriminate among plant and soil science textbooks. The study was to select the RGL indices suited to quantify the readability of these sources, and to identify the factors affecting…
