Resum
ACADEMIC E-BOOKS: EFFECTS OF NAVIGATION STRUCTURE, PREVIOUS NAVIGATION EXPERIENCE, PREVIOUS KNOWLEDGE, AND WORKING
Expository text is one of the most important tools of education. Advances in information technology make educational contents in digital format increasingly common. Hypertext technology allows the presentation of content in terms of information nodes linked in multiple ways, and require the reader to navigate the information in order to construct a coherent mental model. Hypertext comprenhension depends on many factors, grouped as hypertext structure and design, subject variables, and type of task and context (Dillon & Jobst, 2005). This project xamines the effects of different navigation structures (hierarchical, network, linear), readers' knowledge and prior experience of navigation, readers' prior knowledge of the topic, and working memory capacity, in navigation and comprehension of academic texts in digital format. Two experiments in different university contexts are proposed. The project also seeks to transfer results to the UBA university community, in collaboration with EUDEBA. Experiment 1 studies the effect of prior knowledge, prior experience of navigation, working memory capacity, and the hypertext structure (hierarchical, treeshaped, vs. network of interconnected nodes) in reading comprehension of expository hypertexts, in first-year students at the Psychology college, UBA. A similar methodology and design than in previous studies is employed (Burin et al.,2010, 2011). But unlike previous studies, texts to be implemented in two different hypertext structures (hierarchical, network) will be adapted from the EUDEBA digital books catalog. Experiment 2 seeks to extend the study to a population of interest for the UBA and EUDEBA: Students at UBA XXI. They are entry-level students with very scarce domain specific knowledge, who attend semi-virtual courses. It is the public to whom EUDEBA directs their first e-books developed entirely in digital format. Therefore, Experiment 2 will explore comprehension of digital texts, as a function of hypertext structure, navigation knowledge and experience, and working memory capacity of the participants. To better understand natural settings, the linear structure of the typical e-book (navigation forward and backward) is also tested. Results are expected to contribute to improvements in e-book design.
