Teaching Visually Impaired College Students in Introductory Statistics

Instructors of postsecondary classes in statistics rely heavily on visuals in their teaching, both within the classroom and in resources like textbooks, handouts, and software, but this information is often inaccessible to students who are blind or visually impaired (BVI). The unique challenges involved in adapting both pedagogy and course materials to accommodate a BVI student may provoke anxiety among instructors teaching a BVI student for the first time, and instructors may end up feeling unprepared or “reinventing the wheel.” We discuss a wide variety of accommodations inside and outside of the classroom grounded in the empirical literature on cognition and learning and informed by our own experience teaching a blind student in an introductory statistics course

AXMEDIS 2007 Conference Proceedings

The AXMEDIS International Conference series has been established since 2005 and is focused on the research, developments and applications in the cross-media domain, exploring innovative technologies to meet the challenges of the sector. AXMEDIS2007 deals with all subjects and topics related to cross-media and digital-media content production, processing, management, standards, representation, sharing, interoperability, protection and rights management. It addresses the latest developments and future trends of the technologies and their applications, their impact and exploitation within academic, business and industrial communities

Instructional eLearning technologies for the vision impaired

The principal sensory modality employed in learning is vision, and that not only increases the difficulty for vision impaired students from accessing existing educational media but also the new and mostly visiocentric learning materials being offered through on-line delivery mechanisms. Using as a reference Certified Cisco Network Associate (CCNA) and IT Essentials courses, a study has been made of tools that can access such on-line systems and transcribe the materials into a form suitable for vision impaired learning. Modalities employed included haptic, tactile, audio and descriptive text. How such a multi-modal approach can achieve equivalent success for the vision impaired is demonstrated. However, the study also shows the limits of the current understanding of human perception, especially with respect to comprehending two and three dimensional objects and spaces when there is no recourse to vision

Innovation and social learning in higher education institutions

Considering the existing experiences and the concrete needs of the hearing - impaired and visually - impaired groups for accessing HEI programmes, this handboook brings some important innovations: 1. A functional approach, proposing the methods and procedures to be used for developing and delivering ICT based learning offer valid also for these target group (not specially done for them, but designed in such a way that correspond also to their specific needs). This is that will support the target groups in their education and also social inclusion. 2. A subsequent proposal of a kind of “Quality Label”, to establish quality standards and assessment procedures and instruments to be used for evaluating whether Higher Educational Institutions’ offers and training programmes correspond to the ISOLearn standards regarding the accessibility of these groups to their learning offer. 3. Both the Handbook and the “Quality Label” should be tested on a specific qualification which should become a benchmark for the HEI ICT based learning programmes. The concrete experience will demonstrate the benefits for all the stakeholders (e.g. HEI and disadvantaged groups) of promoting social learning approach in HEI.info:eu-repo/semantics/publishedVersio

Multisensory learning in adaptive interactive systems

The main purpose of my work is to investigate multisensory perceptual learning and sensory integration in the design and development of adaptive user interfaces for educational purposes. To this aim, starting from renewed understanding from neuroscience and cognitive science on multisensory perceptual learning and sensory integration, I developed a theoretical computational model for designing multimodal learning technologies that take into account these results. Main theoretical foundations of my research are multisensory perceptual learning theories and the research on sensory processing and integration, embodied cognition theories, computational models of non-verbal and emotion communication in full-body movement, and human-computer interaction models. Finally, a computational model was applied in two case studies, based on two EU ICT-H2020 Projects, "weDRAW" and "TELMI", on which I worked during the PhD

Program Comprehension Through Sonification

Background: Comprehension of computer programs is daunting, thanks in part to clutter in the software developer's visual environment and the need for frequent visual context changes. Non-speech sound has been shown to be useful in understanding the behavior of a program as it is running. Aims: This thesis explores whether using sound to help understand the static structure of programs is viable and advantageous. Method: A novel concept for program sonification is introduced. Non-speech sounds indicate characteristics of and relationships among a Java program's classes, interfaces, and methods. A sound mapping is incorporated into a prototype tool consisting of an extension to the Eclipse integrated development environment communicating with the sound engine Csound. Developers examining source code can aurally explore entities outside of the visual context. A rich body of sound techniques provides expanded representational possibilities. Two studies were conducted. In the first, software professionals participated in exploratory sessions to informally validate the sound mapping concept. The second study was a human-subjects experiment to discover whether using the tool and sound mapping improve performance of software comprehension tasks. Twenty-four software professionals and students performed maintenance-oriented tasks on two Java programs with and without sound. Results: Viability is strong for differentiation and characterization of software entities, less so for identification. The results show no overall advantage of using sound in terms of task duration at a 5% level of significance. The results do, however, suggest that sonification can be advantageous under certain conditions. Conclusions: The use of sound in program comprehension shows sufficient promise for continued research. Limitations of the present research include restriction to particular types of comprehension tasks, a single sound mapping, a single programming language, and limited training time. Future work includes experiments and case studies employing a wider set of comprehension tasks, sound mappings in domains other than software, and adding navigational capability for use by the visually impaired
