RESUMO
The digital revolution has made a multitude of text documents from highly diverse perspectives on almost any topic easily available. Accordingly, the ability to integrate and evaluate information from different sources, known as multiple document comprehension, has become increasingly important. Because multiple document comprehension requires the integration of content and source information across texts, it is assumed to exceed the demands of single text comprehension due to the inclusion of two additional mental representations: the integrated situation model and the intertext model. To date, there is little empirical evidence on commonalities and differences between single text and multiple document comprehension. Although the relationships between single text and multiple document comprehension can be well distinguished conceptually, there is a lack of empirical studies supporting these assumptions. Therefore, we investigated the dimensional structure of single text and multiple document comprehension with similar test setups. We examined commonalities and differences between the two forms of text comprehension in terms of their relations to final school exam grades, level of university studies and university performance. Using a sample of n = 501 students from two German universities, we jointly modeled single text and multiple document comprehension and applied a series of regression models. Concerning the relationship between single text and multiple document comprehension, confirmatory dimensionality analyses revealed the best fit for a model with two separate factors (latent correlation: 0.84) compared to a two-dimensional model with cross-loadings and fixed covariance between the latent factors and a model with a general factor. Accordingly, the results indicate that single text and multiple document comprehension are separable yet correlated constructs. Furthermore, we found that final school exam grades, level of university studies and prior university performance statistically significant predicted both single text and multiple document comprehension and that expected future university performance was predicted by multiple document comprehension. There were also statistically significant relationships between multiple document comprehension and these variables when single text comprehension was taken into account. The results imply that multiple document comprehension is a construct that is closely related to single text comprehension yet empirically differs from it.
RESUMO
BACKGROUND: With digital technologies, competence assessments can provide process data, such as mouse clicks with corresponding timestamps, as additional information about the skills and strategies of test takers. However, in order to use variables generated from process data sensibly for educational purposes, their interpretation needs to be validated with regard to their intended meaning. AIMS: This study seeks to demonstrate how process data from an assessment of multiple document comprehension can be used to represent sourcing, which summarizes activities for the consideration of the origin and intention of documents. The investigated process variables were created according to theoretical assumptions about sourcing, and systematically tested for differences between persons, units (i.e., documents and items), and properties of the test administration. SAMPLE: The sample included 310 German university students (79.4% female), enrolled in several bachelor's or master's programmes of the social sciences and humanities. METHODS: Regarding the hierarchical data structure, the hypotheses were analysed with generalized linear mixed models (GLMM). RESULTS: The results mostly revealed expected differences between individuals and units. However, unexpected effects of the administered order of units and documents were detected. CONCLUSIONS: The study demonstrates the theory-informed construction of process variables from log-files and an approach for empirical validation of their interpretation. The results suggest that students apply sourcing for different reasons, but also stress the need of further validation studies and refinements in the operationalization of the indicators investigated.
