Blue hypertext is a perfect design decision: No perceptual disadvantage in reading and successful highlighting of relevant information

Highlighted text in the Internet (i.e. Hypertext) is predominantly blue and underlined. The percept of these hypertext characteristics were heavily questioned by applied research and empirical tests resulted in inconclusive results. The ability to identify blue text in foveal and parafoveal vision was identified as potentially constrained by the low number of foveally centered blue light sensitive retinal cells. The present study investigates if foveal and parafoveal perceptibility of hypertext is reduced during reading. A silent-sentence reading study with simultaneous eye movement recordings and the invisible boundary paradigm, which allows the investigation of foveal and parafoveal perceptibility, separately, was realized. Target words in sentences were presented in either black or blue and either underlined or normal. No effect of color and underlining, but a preview benefit could be detected for first pass reading measures (comparing fixation times after degraded vs. un- degraded parafoveal previews). Fixation time measures that included re-reading (i.e., total viewing times) showed, in addition to a preview effect, a reduced fixation time for not highlighted (black not underlined) in contrast to highlighted target words (either blue or underlined or both). Thus, the present pattern reflects no detectable perceptual disadvantage of hyperlink stimuli but increased attraction of attention resources, after first pass reading, through highlighting. Blue or underlined text allows readers to easily perceive hypertext and at the same time readers re-visited hypertext longer as a consequence of highlighting. On the basis of the present evidence blue hypertext can be safely recommended to web designers for future use.Comment: 15 pages, 1 figure, 1 tabl

Development of multiple media documents

Development of documents in multiple media involves activities in three different fields, the technical, the discoursive and the procedural. The major development problems of artifact complexity, cognitive processes, design basis and working context are located where these fields overlap. Pending the emergence of a unified approach to design, any method must allow for development at the three levels of discourse structure, media disposition and composition, and presentation. Related work concerned with generalised discourse structures, structured documents, production methods for existing multiple media artifacts, and hypertext design offer some partial forms of assistance at different levels. Desirable characteristics of a multimedia design method will include three phases of production, a variety of possible actions with media elements, an underlying discoursive structure, and explicit comparates for review

Student centred legal language study

The article introduces parts of a self-study programme for LLB (Europe) German students, which include the use of satellite TV and CALL. The whole self-study programme was tested for two years at the Nottingham Trent University. This paper focuses on the rationale of the study programme, pedagogical objectives and theoretical considerations within the context of language learning as well as the students’ evaluation. The evaluation shows that overall the package was seen as a positive learning experience. CALL can be a solution to the problem of limited materials for languages for specific purposes. The use of mixed media is possible for language teaching for specific purposes without having to be combined in multimedia computer-based programmes. CALL can also be a solution to the problems caused by reduced contact time

The use of additional information in problem-oriented learning environments

Self-directed learning with authentic and complex problems (problem-oriented learning) requires that learners observe their own learning and use additional information when it is appropriate – e.g. hypertextual information in computer-supported learning environments. Research results indicate that learners in problem-oriented learning environments often have difficulties using additional information adequately, and that they should be supported. Two studies with a computer-supported problem-oriented learning environment in the domain of medicine analyzed the effects of strategy instruction on the use of additional information and the quality of the problem representation. In study 1, an expert model was used for strategy instruction. Two groups were compared: one group with strategy modeling and one group without. Strategy modeling influenced the frequency of looked-up hypertextual information, but did not influence the quality of learners' problem representations. This could be explained by difficulties in applying the general hypertext information to the problem. In study 2, the additional information was presented in a more contextualized way as graphical representation of the case and its relevant concepts. Again, two groups were compared: one with a strategy instruction text and one without. Strategy instruction texts supported an adequate use of this graphical information by learners and had an effect on the quality of their problem representations. These findings are discussed with respect to the design of additional help systems in problem-oriented learning environments

Reading in Web-based hypertexts: cognitive processes strategies and reading goals

Hypertext is a multi-linear electronic, textual and interactive environment to present information. The objective of such an environment is that readers may browse through linked, cross-referenced, annotated texts in a multi-sequential manner, and thus, it is believed, to improve the learning. However, early and current research findings have revealed some mixed results concerning the alleged advantage of hypertext on learning over paper-based documents. Researchers have identified the lack of research about the cognitive processes and the strategies that readers use during reading as one of the main factors for such results. As a result, there is a need and scope for further research in modelling the cognitive processes involved in reading comprehension and the reading strategies in a hypertext environment. This research addresses some of the gaps in the field by proposing a model that represents the sequence of events that take place during reading in a Web-based hypertext environment. Also, emphasis is placed on the strategies that readers use during hypertext reading and on the potential effect of different reading goals on reading comprehension. The evaluation of the model and the other hypotheses is conducted in two experiments using qualitative and quantitative methods. The first experiment employs the think aloud method. Forty two subjects participated. The results demonstrated that the proposed model precisely describes the sequence of events that take place during hypertext reading. They did not reveal any significant difference between different reading goals and understanding. They revealed four reading strategies: serial, serial overview, mixed, and mixed overview, and they identified three factors that influence the selection of hyperlinks: coherence, link location, and personal interest. The second experiment is an independent samples design experiment with ninety subjects. The results confirmed those found in the first experiment. The current study makes a contribution in the field of hypertext reading by proposing and evaluating a procedural model and by making this model graphic. By doing so it addresses some of the voids in the field, expands our understanding of the reading processes and the reading strategies, and provides practical guideliness which are enhanced to promote design supporting effective learning processes

Flexibility and Interaction at a Distance: A Mixed-Model Environment For Language Learning

This article reports on the process of design and development of two language courses for university students at beginning levels of competence. Following a preliminary experience in a low-tech environment for distance language learning and teaching, and a thorough review of the available literature, we identified two major challenges that would need to be addressed in our design: (1) a necessity to build sufficient flexibility into the materials to cater to a variety of learners' styles, interests and skill levels, therefore sustaining learners' motivation; and (2) a need to design materials that would present the necessary requisites of authenticity and interactivity identified in the examined literature, in spite of the reduced opportunities for face-to-face communication. In response to these considerations, we designed and developed learning materials and tasks to be distributed on CD-ROM, complemented by a WebCT component for added interactivity and task authenticity. Although only part of the original design was implemented, and further research is needed to assess the impact of our environment on learning outcomes, the results of preliminary evaluations are encouraging

Visualising Discourse Coherence in Non-Linear Documents

To produce coherent linear documents, Natural Language Generation systems have traditionally exploited the structuring role of textual discourse markers such as relational and referential phrases. These coherence markers of the traditional notion of text, however, do not work in non-linear documents: a new set of graphical devices is needed together with formation rules to govern their usage, supported by sound theoretical frameworks. If in linear documents graphical devices such as layout and formatting complement textual devices in the expression of discourse coherence, in non-linear documents they play a more important role. In this paper, we present our theoretical and empirical work in progress, which explores new possibilities for expressing coherence in the generation of hypertext documents

ImpacT2 project: preliminary study 1: establishing the relationship between networked technology and attainment

This report explored teaching practices, beliefs and teaching styles and their influences on ICT use and implementation by pupils. Additional factors explored included the value of school and LEA policies and teacher competence in the use of ICT in classroom settings. ImpaCT2 was a major longitudinal study (1999-2002) involving 60 schools in England, its aims were to: identify the impact of networked technologies on the school and out-of-school environment; determine whether or not this impact affected the educational attainment of pupils aged 816 years (at Key Stages 2, 3, and 4); and provide information that would assist in the formation of national, local and school policies on the deployment of IC

Hypermedia literacy: an insight into English as a Foreign Language online reading processes

The advent of the Internet has generated new ways of reading for knowledge, suggesting that digital literacy is a necessity for students of this new era. Even so, there is still a dearth of knowledge in the field that can provide rich theoretical descriptions of online reading processes of English as a Foreign Language (EFL) readers in the hypertext environment. This article elucidates the perceptual learning styles and the metacognitive reading strategies of English as a Foreign Language students in hypertext reading environment. Their perceived preferred practices were elicited through a questionnaire and interviews, while actual observed online behaviours were recorded with Camtasia Studio 7. Based on these data sources, patterns of reading hypermedia texts on an online reading platform were identified and compared using NVivo 9. The findings indicated that the students’ perceived as well as their preferred learning styles and metacognitive reading strategies were mostly not performed or applied by them when they were engaged in the actual hypermedia reading environment. These differences in behaviours were contributed to the reading tasks and hypermedia tools made available by the platform facilitating their reading processes. Most significantly, the study revealed that the types of hypermedia tool available enabled them to modify their previously preferred practices for other ways of reading and comprehending the hypermedia texts. Moreover, the findings have also implied that students reading hypermedia texts online can develop different choices of sensory pathways unique to digital literacy environments. Thus the findings are significant as they contribute towards the currently limited knowledge about electronic literacy and online reading processes
