Dealing with multiple documents on the WWW: The role of metacognition in the formation of documents models

Drawing on the theory of documents representation (Perfetti, Rouet, & Britt, 1999), we argue that successfully dealing with multiple documents on the WWW requires readers to form documents models, that is, to deal with contents and sources. We present a study in which we tested the assumption that the use of metacognitive strategies is crucial to the formation of documents models. A total of 100 participants with little medical knowledge were asked to conduct an Internet research on a medical topic. Participants were randomly assigned to four experimental groups that either received evaluation prompts, monitoring prompts, both types of prompts, or no prompts. A control group took paper-and-pencil notes. Results showed that laypersons receiving evaluation prompts outperformed controls in terms of knowledge about sources. In addition, laypersons receiving monitoring prompts acquired significantly more knowledge about facts, and performed slightly better on a comprehension test. It is concluded that the results underline the importance of metacognition in dealing with multiple docu-
