Vocabulary knowledge is one of the most important elements of reading comprehension. Text coverage is the proportion of known words in a given text. We hypothesize that text comprehension increases exponentially with text coverage due to network effects and activation of prior knowledge. In addition, the lexical threshold hypothesis states that…

Readers often struggle to identify the main ideas in expository texts. Existing research and instruction provide some guidance on how to encourage readers to identify main ideas. However, there is substantial variability in how main ideas are operationalized and how readers are prompted to identify main ideas. This variability hinders…

Though the empirical findings of the past studies in the literature have offered strong support to the significant role of language knowledge and background knowledge in reading comprehension, this issue has not been explored with regard to specific purposes tests in the Iranian higher education context. Therefore, this study aimed at exploring…

The purpose of this study was to investigate bridging inferences and learning when students with low topic knowledge read multiple complementary biology texts. Using a think-aloud protocol, we assessed students' (n = 74) cognitive processes while they read one text about principles of natural selection and three texts about examples of natural…

Uganda Baptist Seminary (UBS) is accredited by the Ugandan National Council for Higher Education and teaches church leaders from Uganda and its surrounding seven countries. The required language of educational instruction is English, although the students come from a multitude of different native languages. This research stems from a need to…

This study demonstrates the generalization of previous laboratory results showing the benefits of self-explanation reading training (SERT) to college students' course exam performance. The participants were 265 students enrolled in an Introductory Biology course, 59 of whom were provided with SERT training. The results showed that SERT benefited…

We used a design-based research model to examine a historical literacy intervention in Grade 6 classrooms. This article describes the results across 2 separate instructional cycles and for students grouped into 4 categories: (a) high-achieving students (n = 23 and n = 24 for Cycle I and Cycle II, respectively), (b) average-achieving students (n =…

This study explores differences in students' reading comprehension of International Financial Reporting Standards in a South African financial reporting class with a heterogeneous student cohort. Statistically significant differences were identified for prior academic performance, language of instruction, first language and enrolment in the…

This paper considers whether the sources of linguistic complexity presented within texts targeted at 1st-grade readers have increased, decreased, or held steady over the 52-year period from 1962 to 2013. A collection of more than 450 texts is examined. All texts were selected from Grade 1 textbooks published by Scott Foresman during the targeted…

Argues that readability formulas accurately predict how easily a passage will be understood by considering sentence length and word difficulty. Claims that the misuse of readability formulas as writing guides is responsible for much of the criticism. Challenges the critics to come up with something better. (RS)

Eighteen naval fire technicians served as subjects in a study using scenarios to simulate a real world task for assessing the readability of general technical texts. The scenario asked subjects to read a segment of text and to explain to a colleague how the particular component described in the passage functioned. Subjects' summaries were assessed…

Two studies investigated the relationships between readability, prior knowledge, and interest in the material being read. In the first study, 169 college freshmen read cloze passages of materials from the Nelson-Denny Reading Tests, then one week later read the whole passages and completed the related multiple choice questions. A control group…

A study examined students' ability to comprehend consistent or inconsistent text when activating relevant or irrelevant background knowledge. Fifty-five grade six students reading at or above grade level were randomly assigned to one of four treatment groups: activated/consistent, nonactivated/consistent, activated/inconsistent, and…

Recent studies refuting the effectiveness of advance organizers in preparing students to comprehend text material have not met the conditions necessary for advance organizers to succeed. According to the assimilation theory, which holds that people learn by chaining what is known to what is to be learned, the following conditions must be met for…
