This study examined the influence of three personal factors, namely, prior knowledge about the text topic, external strategy use during reading, and experience in college, on students' comprehension of the relations among controversial texts. Eighty-six one-year and 80 three-year undergraduate students answered a questionnaire assessing topic knowledge. One week later, they read two controversial texts and then completed two tasks assessing their comprehension of intertextual relations and recall of intratextual arguments respectively. The results indicated that topic knowledge influenced the comprehension of intertextual relations through enhancing the processing of intratextual arguments. The production of summary notes during reading had indirect and direct positive effects. Longer experience in college led to a better understanding of intertextual relations.
Comprehension of controversial texts 3The Influence of Topic Knowledge, External Strategy Use, and College Experience on Students'
Comprehension of Controversial TextsControversial texts, two or more written texts that give different views on an issue, are familiar to people in democratic society. They are a major mode of legal, political, social, and scientific discourse. For example, a controversy over policy is often developed through newspapers, magazines, books, and websites. Those who intend to follow or participate in the controversy must be able to deal with multiple texts that argue for or against the policy.Proficiency in reading controversial texts is necessary for becoming active citizens, let alone experts in each discourse (Chall, 1996;Westby, 2004;Wineburg, 1991).This article concerns the influence of personal factors on students' comprehension of controversial texts. In particular, I concentrated on their comprehension of the relations among the texts. It involves detecting discrepancies among the texts and identifying what the writers agree or disagree about and their positions toward the issue (Perfetti, Rouet, & Georgi, 1999;Rouet, Britt, Mason, & Perfetti, 1996). It is important for readers of controversial texts to understand the intertextual relations precisely; otherwise they may miss the points in dispute, accept even contradictory statements as true, and bias their judgments on the issue. Unsurprisingly, there is evidence that students differ from each other in the comprehension of intertextual relations: the detection of discrepancies among texts (Perfetti, Britt, & Georgi, 1995) and the synthesis of arguments across texts (Stahl, Hynd, Britton, McNish, & Bosquet, 1996;Wolfe & Goldman, 2005). Provided that these differences are systematic, examining the sources of variance can shed some light on what is crucial to students' success in comprehension. Little research attention, however, has been given to personal factors except for discipline expertise.
Consequently, our knowledge is quite limited about what factors account for the differencesComprehension of controversial texts 4 among students, that is, novices in academ...
