Intelligent tutoring systems are adaptive learning environments designed to support individualized instruction. The adaptation embedded within these systems is often guided by user models that represent one or more aspects of students' domain knowledge, actions, or performance. The proposed project focuses on the development and testing of user…

Adaptive learning technologies hold great promise for improving the reading skills of adults with low literacy, but adults with low literacy skills typically have low computer literacy skills. In order to determine whether adults with low literacy skills would be able to use an intelligent tutoring system for reading comprehension, we adapted a 44…

The purpose of this study was to examine the difference between students' scores in comprehension (English Language Arts) tests when they are led in Brain Gym® activities before class instruction and when they are taught using traditional teaching strategies. The sample for this study consisted of 11 males and 9 females. Data were collected by…

To study how the organization of information affects the way that information is interpreted, a total of 404 undergraduates in two studies (151 and 253 students, respectively) solved statistical reasoning problems based on data presented in a variety of types of graphs and tables. When assessing relative probabilities, students were equally…

This study of the effects of computer-assisted instruction (CAI) on the academic achievement of educationally disadvantaged students in grades 2 through 8 in four urban schools tested three hypotheses: (1) supplementary CAI programs are significantly more effective than non-CAI supplementary instruction approaches for disadvantaged students; (2)…

A study was conducted to investigate the reading comprehension and educationally related characteristics and relationships that describe the Navy's recruit population. The variable of primary interest was the recruit's reading comprehension grade level score; other variables were years of education, aptitude score, high school graduation status,…

A study investigated the reading comprehension and educationally related characteristics of the United States Navy's recruit population based on data for selected variables. The variable of primary interest was the recruit's grade level score on reading comprehension; other variable employed in the study were grade level score, years of education,…

Two experiments investigated the role of capacity in children's comprehension of relative clause sentences. Sentences varied in number of participant roles, focus (object, subject), and embeddedness (center-embedded, right-branching). Center-embeddedness and object-focus were expected to constrain individuals toward assigning more nouns to their…

A study investigated the effects of interactive CD-ROM software on children's reading comprehension. It explored whether 31 fourth-grade children in an elementary school in a suburban school district in the Midwest comprehended narratives better when reading from the printed page or from the same text displayed by the computer. One class read each…

Readers possess vast amounts of knowledge gained from their prior experiences and exposures. The more they are helped to use that knowledge for connecting new ideas to known subjects as they read, the better their comprehension will be. Discussions before reading have been a traditional way to activate students' schema for stories, but a new…

A study reanalyzed data from two previous studies to investigate (1) validity of imagery ratings and reports as measures of reader response to a story, and (2) similarity of final regression models for recall and imagery reports. Imagery and affect ratings of story paragraphs were found to predict both imagery reports and recall of a second,…

Some methodological issues in the study of levels of knowledge are reviewed, and needs for further research are explored, drawing on an analysis of 12 studies reported since the late 1970s. In the 12 studies, 16 quantitative experiments were conducted. These were assessed for internal and external validity. Analysis revealed some shortcomings in…

An earlier study found virtually no relationship between college students' reported studying practices and various tests of reading comprehension, so a second study investigated whether different results would be obtained with an instrument based on study strategies college students actually reported using. Scores on this instrument were to be…
