This study explored the dimensionality of multiple-text comprehension strategies in a sample of 216 Norwegian education undergraduates who read seven separate texts on a science topic and immediately afterwards responded to a self-report inventory focusing on strategic multiple-text processing in that specific task context. Two dimensions were identified through factor analysis: one concerning the accumulation of pieces of information from the different texts and one concerning cross-text elaboration. In a subsample of 71 students who were also administered measures of intratextual and intertextual comprehension after responding to the strategy inventory, hierarchical multiple regression analysis indicated that self-reported accumulation of information and cross-text elaboration explained variance in intertextual comprehension even after variance associated with prior knowledge had been removed.Keywords Multiple-text comprehension strategies .

Measuring strategic processingThe main purpose of this study was to design and validate a task-specific self-report measure of strategic multiple-text processing. Building upon the strategy conceptualizations of Weinstein and Mayer (1986) and Alexander et al. (1998), Bråten and Samuelstuen (2004) defined text comprehension strategies as forms of procedural knowledge that readers voluntary use for acquiring, organizing, or transforming text information, as well as for reflecting on and guiding their own text comprehension, in order to reduce a perceived discrepancy between a desired outcome and their current state of understanding. There is much prior research documenting that the use of deeper-level strategies falling in the broad categories of organization, elaboration, and monitoring is particularly important for successful comprehension performance when students read single texts (McNamara 2007; National Reading Panel 2000;Trabasso and Bouchard 2002). Especially, analyses of thinkaloud protocols (Ericsson and Simon 1980) have shown that good readers are strategically Metacognition Learning (2011) 6:111-130 DOI 10.1007 I. Bråten (*) : H. I.

In addition, good readers often jump back and forth in text and distribute their attention unequally, that is, paying more attention to some parts of the text than to others (Pressley and Harris 2006). In contrast, a hallmark of poorer readers seems to be that they read less actively, failing to produce the strategies when reading that good readers use to comprehend text. Moreover, poorer readers are much more likely to read word by word in a linear way (Duke et al. 2004;Pressley and Harris 2006). However, as shown by A...
