Description:

In this project, researchers iteratively developed and tested a web-based search engine and intelligent tutoring system for university students and students in third- through sixth-grade that aimed to improve their reading comprehension and vocabulary growth. The students were to use the search engine to select passages on the Internet on topics of interest that also met specific standards of reading difficulty. As students used the search engine, it analyzed their behavior and developed a profile each individual student's level of acquisition and fluency for each word, producing an individualized framework for selecting reading materials that strengthened that student's reading comprehension. The intelligent tutoring system, called REAP, provided reader-specific lexical practice for improved reading comphrension by selecting authentic reading materials from the Internet that were matched to students' needs.

Structured Abstract

The researchers are carrying out three studies in the process of developing the search engine, two of which involve university students and one of which involves students in the third through sixth grades. The first study involves adults reading texts in three different topic areas (business, arts and leisure, and sports) and three levels of different percentages of unfamiliar words, to measure the effects of these differences on reading times, comprehension, and readers' ability to infer word meanings, assessments of difficulty, and degree of interest. The second study involves students reading texts chosen according to the search engine's criteria for gauging their reading difficulty and taking into account the individual readers' degree of familiarity with the vocabulary, to evaluate the feasibility of individualized text selection using materials drawn from the web. In the third study, the researchers are having students in grades three through six use the search engine to select and practice reading with materials selected from the web that reflect increasing levels of difficulty in the vocabulary words included in the texts, and measuring the development of their reading comprehension.
