Scanning and deep processing of information in hypertext: an eye tracking and cued retrospective think-aloud study
2016
When students solve problems on the Internet, they have to find a balance between quickly scanning large sections of information in web pages and deeply processing those that are relevant for the task. We studied how high school students articulate scanning and deeper processing of information while answering questions using a Wikipedia document, and how their reading comprehension skills and the question type interact with these processes. By analyzing retrospective think-aloud protocols and eye-tracking measures, we found that scanning of information led to poor hypertext comprehension, while deep processing of information produced better performance, especially in location questions. Thi…
Self-Regulation and Link Selection Strategies in Hypertext
2010
This article explores the role of self-regulation in strategies that readers use to decide the order in which to read the different sections of a hypertext. This study explored 3 main strategies for link selection based on (a) link screen position, (b) link interest, and (c) the semantic relation of a link with the section just read. This study followed Winne's (1995, 2001) model of self-regulated learning to try to explain why some readers select hyperlinks based on strategies that lead to lower levels of comprehension (i.e., screen position and personal interest). Results from 2 studies revealed that readers with low prior knowledge base their decisions on what to read next on a default s…
Information structure and practice as facilitators of deaf users' navigation in textual websites
2009
Deaf users might find it difficult to navigate through websites with textual content which, for many of them, constitutes the written representation of a non-native oral language. With the aim of testing how the information structure could compensate for this difficulty, 27 prelingual deaf users of sign language were asked to search a set of headlines in a web newspaper where information structure and practice were manipulated. While practice did not affect deep structures (web content distributed through four layers of nodes), wide structures (web content concentrated in two layers) did facilitate users' performance in the last trial block and compromised it in the first trial block. It is…
Reading skills and children’s navigation strategies in hypertext
2011
Prior research has identified two important navigation strategies that have a clear impact on hypertext comprehension: link selection and overview processing strategies. The first relate to the order in which students select hyperlinks while trying to comprehend a hypertext, whereas the second relate to when and for how long students process navigation overviews, a text device that conveys the text structure by displaying sections, titles and their relations. Most prior research in navigation strategies has been conducted with undergraduate students. We extend prior research by exploring the navigation strategies used by sixth-graders while reading a hypermedia system. We also investigate h…
Children's Reading of Printed Text and Hypertext with Navigation Overviews: The Role of Comprehension, Sustained Attention, and Visuo-Spatial Abiliti…
2012
Hypertexts include new structural features, such as navigable graphical overviews, that dramatically change the way students interact with texts. Nevertheless, at school students traditionally practice literacy skills appropriate for reading and comprehending printed texts. We explored the possibility that those skills might not be the same as the ones required to master hypertext reading. Specifically, we tested the hypothesis that hypertext structural features, such as navigable graphical overviews, might scaffold students with low comprehension and sustained-attention abilities, but demand higher involvement of visuo-spatial skills. Results from a group of 6th-grade students only partia…
A multimedia approach to the efficient implementation and use of emergency plans
2004
Because of the complexity of emergency procedures, the stressful situations during which they're executed, the emergency plan must be meticulously designed so that safety managers can quickly find needed information. Regardless of the complex procedures it describes and the trying situations where it would be used, the plan's success is always measured by how effective the evacuation is. Thus, safety-conscious organizations continually try to improve their emergency procedures and the way they present them in the emergency plan. Integrating incoming information during an emergency and correlating this information with the plan's procedures is a manual task for many safety managers. The dang…
Who Benefits from WWW Presentation in the Basics of Informatics?
2011
This paper describes the use of WWW-based guided tours as a complementary addition to conventional lectures in the basics of informatics. Learning can be promoted in the spirit of constructivism, situated action, and cognitive flexibility when organizing a WWW coursework. We analyze the benefit of an optional coursework, including the use of guided tours and the use of search engines and directories on the WWW. This paper presents who benefits and who does not benefit from our optional coursework. The analysis is based on the background information and prior computer experience of the students, as well as pre and post tests. The study found that our WWW-based coursework suits best for femal…
Rereadings: Highlighting the Gender Perspective Through Hypermedia
2020
In this text, we present the contributions of the Spain-based project Rereadings. Museum Itineraries from a Gender Perspective, which aims to present to the public the collections of 11 Valencian museums, of various kinds and under different types of ownership, from a gender and queer perspective. Rereadings uses virtual itineraries and QR codes to contribute to the study of gender. Thus, technology is used as a basis for information dissemination, analysis, and debate. The struggle against androcentrism and heteropatriarchy has generated a greater inclusion of women, other genders, and diverse sexualities in traditional museum discourse. New technologies function as one of the fundamental …
Does Navigation Always Predict Performance? Effects of Navigation on Digital Reading are Moderated by Comprehension Skills
2016
<p align="left">This study investigated interactive effects of navigation and offline comprehension skill on digital reading performance. As indicators of navigation relevant page selection and irrelevant page selection were considered. In 533 Spanish high school students aged 11-17 positive effects of offline comprehension skill and relevant page selection on digital reading performance were found, while irrelevant page selection had a negative effect. In addition, an interaction between relevant page selection and offline comprehension skill was found. While the effect of relevant page selection was strong in good offline comprehenders, it was significantly reduced in weak offline c…
Do graphical overviews facilitate or hinder comprehension in hypertext?
2009
Educational hypertexts usually include graphical overviews, conveying the structure of the text schematically with the aim of fostering comprehension. Despite the claims about their relevance, there is currently no consensus on the impact that hypertext overviews have on the reader's comprehension. In the present paper we have explored how hypertext overviews might affect comprehension with regard to (a) the time at which students read the overview and (b) the hypertext difficulty. The results from two eye-tracking studies revealed that reading a graphical overview at the beginning of the hypertext is related to an improvement in the participant's comprehension of quite difficult hypertexts…
