Is Hearing Believing? Perception of Online Information Credibility by Screen Reader Users who are Blind or Visually ImpairedChandrashekar, Sambhavi 15 February 2011 (has links)
While credibility perception on the Web is a well-researched topic across multiple disciplines, extant studies have not considered nonvisual modalities of Web access. This research explores how Web users who are blind or visually impaired perceive the credibility of online information and how the screen reader used by them to interact with the Web mediates the process. Credibility perception was studied in the context of the screen reader users’ everyday information practices, examining in depth the effect of Web accessibility on their online information interactions, information practices and credibility perception. Adopting an exploratory approach, a sequential multimethods research design was used. Between April and July 2008 data were collected from adult screen reader users residing in Ontario, Canada through an electronic questionnaire survey (N=60) to identify salient issues, which were then examined deeper through semi-structured interviews with a subsample (N=13) during June 2009. Hands-on online information activities (with participant observation and think-aloud protocol) were also conducted during the interview session. Primary findings emerged through qualitative content analysis of descriptive data, with quantitative results guiding and supplementing the analysis. Online information credibility perception is found to be a dynamic and social process. It is governed by users’ assumptions based on their past experiences, personal knowledge/beliefs and social inputs. Assumptions evolve over time and usage into personal heuristics. The credibility perception process spans three phases—prediction, evaluation and corroboration—permeating the information seeking, using and sharing practices of users. Evaluation of website and web content depends on users’ online interaction proficiency and is bounded by the interface affordances provided by the screen reader and the amount of meta-information provided by the websites for interpreting visual/spatial features. Community support scaffolds users towards more effective technology management and credibility perception. Therefore, promoting inclusion in the online participatory culture will enhance the information practices of screen reader users.

Tillgänglighet, en förmån eller en avlägsenhet? : tillgänglighet för synskadade på museer och förmedling av arkeologi / Availability, a benefit or a remoteness? : accessibility for the Visually Impaired in museums and communication of archeologyEngström, Cecilia January 2013 (has links)
This bachelor thesis brings up a discussion about museums availability and access to thearchaeological display objects towards blind and visually impaired visitors. The study phasewill take start in analyzing four museums in south Sweden, all which have exhibitions aboutthe prehistory.Visually impaired and blind visitors don’t have a lot to go on at the current exhibitions aboutprehistory. This is because of the lack of access and availability when it comes to their specialneed. To raise awareness to this problem I took out a survey for the museums to answer. I alsovisited two of the exhibitions to make my own opinion of the museums public areas; such asthe entrance, hallway and the exhibition area. Things I looked out for were Braille, audioguides and objects to touch.The sense to touch is of most importance for visually impaired and blind to create an image ofan object. Because of this I discuss the ability for an exhibition where most of the objects areexposed to all visitors to be touched. An exposure of archaeological object to benefit needsfor visually impaired is an important discussion towards the management of thearchaeological display objects, which leads the study towards replicas and experimentalarchaeology.The conclusion was that it is quite possible to design and customize an archaeologicalexhibition for the visually impaired by factors like; reconstructed objects, route marker fororientation, Braille and audio guides with well rendered image descriptions.

A case study revealing how preservice art educators develop awareness of the role of language during field work in art education for pupils who are blind or visually impairedKeating, Jannette 20 November 2013 (has links)
Working collaboratively with the Texas School for the Blind and Visually Impaired (TSBVI) and Dr. Kara Hallmark's art education students at the University of Texas at Austin (UT), this qualitative case study documented how preservice art teachers' awareness of how to implement language as a teaching tool developed during a participatory observational experience in the segregated special needs art class at TSBVI. My research reveals how the field experience at TSBVI, which included hands-on interaction with pupils who are blind or visually impaired and the role modeling of an experienced special needs art educator, enhanced awareness for preservice teachers about how language can be used effectively in teaching art. This awareness is useful for all educators who include students experiencing vision impairment in the art classroom. / text

Science for All: Experiences and Outcomes of Students with Visual Impairment in a Guided Inquiry-based ClassroomRooks, Deborah Lynn January 2009 (has links)
The purpose of this study was to examine instructional experiences of students with visual impairment in an guided inquiry-based science classroom. Drawing from social constructive perspectives about teaching and learning, I focused on the initial attempts of students to participate fully in an inquiry-based astronomy unit. The astronomy unit incorporated features of project-based science inquiry and aligned with national standards. This study described the opportunities provided to and challenges faced by students with visual impairment as they participated in the guided inquiry-based learning environment. Additionally, discursive practices of students including student-generated questions, student discussions, and students' science notebook writing were examined. Also, students' alternative conceptions about scientific phenomena and changes in students' thinking during the course of instruction, if any, were described. Methods of data collection included classroom observations, video records, pre- and post- curriculum assessments, attitudes toward science measurement, student interviews, and student artifacts (i.e., science notebook entries, student-constructed models). Findings showed that student learning was enhanced when the instructor-researcher guided students in accomplishing inquiry tasks and in making sense of their inquiry experiences. Additionally, the use of appropriate reflective prompts assisted students with visual impairment to fully participate in the writing tasks of the inquiry-based learning environment. Results suggested that the quantity and quality of student-generated questions increased with extended inquiry instruction. Also, students used questions to not only establish verbal communication, but to elaborate on their own thinking and expand or explain the thinking of others. Findings suggested also that students with visual impairment have similar alternative frameworks about scientific phenomena (i.e, causes of lunar phases, reason for the seasons) as do their peers with sight. This study contributes to the literature about inquiry-based instructional strategies for all students and initiates the conversation about best practice for science instruction with students with visual impairment.

Equality and non discrimination in tertiary education for the visually impairedJustin Pillay January 2009 (has links)
<p>The focus of this paper is the right of the visually impaired to access tertiary education that is not unfairly discriminative and unequal. The study is intended to highlight the inadequacy in the current legislation on equality such as the Promotion of Equality and Prevention of Unfair Discrimination Act 4 of 2000 and the Higher Education Act 101 of 1997 in properly promoting the ideals and purpose of constitution. Furthermore to analyse the constitutional court's approach to equality and non discrimination in order to provide solutions and recommendations for changes to existing legislation that is indeed to be effective.It also aim to define what it means to have equality for the visually impaired, more especially in tertiary education through the constitutional court's definition of equality...</p>

Web accessibilty : A middleware prototype for visually impaired usersSalvador Astals, David January 2014 (has links)
In the context of a society were the Web is present in many aspects, there is asignificant amount of visually impaired users whose experience is far from beingsatisfactory. There are technologies aiming this problem but still with no full suc-cess. The problem addressed in this project is the existing gap between the visuallyimpaired users and the solutions being offered to them. As a solution to this problem,a middleware prototype is developed. It acts as a web application so the user doesnot need to install anything. The middleware also offers different adaptations to theuser such as amplifying lens, text narrator, and others. The solution was tested byvisually impaired users and it received an overall positive result. Some features likethe amplifying lens received a good value and some of them need further improve-ment.

A experiência como fator determinante na representação espacial do deficiente visual /Ventorini, Silvia Elena. January 2007 (has links)
Resumo: Este trabalho discute a utilização do Sistema Maquete Tátil/Mapavox por três grupos de alunos: cegos, de baixa visão e normovisuais, sob a perspectiva de análise não comparativa de resultados. Os objetivos do trabalho foram investigar como as pessoas deficientes visuais organizam os objetos no espaço e que estratégias usam para constituir suas representações. No embasamento teórico dialogase com autores que realizaram pesquisas sobre os desenvolvimentos motor e cognitivo de crianças cegas e suas relações com o espaço partindo do próprio cego, sem comparálo às pessoas dotadas de visão. Os resultados indicam que os sujeitos deficientes visuais organizam os objetos no espaço de forma diferente das pessoas normovisuais e que a adaptação de material didático de Cartografia para este público não consiste simplesmente em substituir cores por texturas, efetuar contornos em relevo e/ou inserir informações em braille e em escrita convencional ampliada. Indicam ainda que, as abordagens de conteúdos geográficos e cartográficos não podem ter como referencial a percepção e organização espacial de pessoas que enxergam. A análise dos resultados aponta que as formas de organização do espaço nos sujeitos deficientes visuais trazem as marcas de suas experiências. Por isso, organizam o espaço expressando rotas ou ambientes que possuem significativa vivência. / Abstract: This paper discusses the use of the Tactile Model System /Mapavox by three groups of students: the blind; the visually impaired and the students with normal vision, under the perspective of an analysis of non comparative results. The goals of the work went investigate as the blind and visually impaired organize the objects in the space and that strategies use to constitute its representations. The theoretical basis brings authors who performed researches on the motor and cognitive development of blind children as well as their relation to space without comparing it to that of people with no visual impairment. The results obtained indicate that the blind and visually impaired subjects have a different spatial organization than those with normal vision and the adaptation of Cartographic didactic materials for the visually impaired does not consist of just substituting colors for texture, or using contoured relieves and or inserting information in Braille and amplified conventional writing. Thus, the content approach of both Geography and Cartography cannot have as a referential the perception and spatial organization of individuals with normal vision. The analysis of the results aims that the forms of organization of the space subjects bring the marks of its experiences. / Orientador: Maria Isabel Castreghini de Freitas / Coorientador: José Antônio dos Santos Borges / Banca: Katia Regina Moreno Caiado / Banca: Rosângela Doin de Almeida / Mestre

Previous issue date: 2018-02-27 / O presente trabalho teve por objetivo analisar os efeitos da prática do Goalball no processo da mobilização da aprendizagem dos fenômenos e conceitos físicos de uma aluna e um aluno com deficiência visual nas aulas de Física, a partir de uma experiência vivenciada na escola. Ressalta-se que, quando se fala em uma educação para todos e todas, remete-se à ideia de dar oportunidades aos alunos e alunas, de acesso e permanência na escola, com as mesmas igualdades de condições, respeitando suas singularidades. Ao se abordar a questão das diferenças, não se remete somente às minorias ou às crianças com necessidades especiais. É muito mais amplo, pois todos nós seres humanos somos únicos, portanto diferentes uns dos outros. Adotou-se como aporte teórico a Mobilização, uma categoria da Relação com o Saber (Charlot, 2000) para a realização da pesquisa. Tendo como questão central: Qual o papel do Goalball no processo da mobilização da aprendizagem do aluno com deficiência visual no Ensino de Física? Procurou-se refletir sobre o envolvimento em uma atividade que gere sentido, desejo e prazer no processo de ensino e aprendizagem dos alunos. Foram dois alunos participantes, um aluno que tem sua identidade construída no sexo masculino (matriculado no 3º ano do ensino médio) e outra no sexo feminino (matriculada no 3 ano do ensino médio). Trata-se de uma pesquisa qualitativa do tipo participativa, tendo como instrumentos de coleta de dados as Observações das aulas, Diário de campo, Balanço do Saber Reorganizado, Entrevista Semiestruturada e a Organização dos Dados, baseados na Análise Descritiva, Gil (2008). Nesse contexto, a pesquisa nos expõe que os efeitos produzidos pelo Goalball nas aulas de física nos estudantes foram: a Mobilização, Pesquisar, Relembrar, Aprender mais facilmente, Resignificar e Entender Melhor sobre os fenômenos e conceitos fisicos apresentados. / The aim of the present work was to understand the effects of Goalball practice in mobilizing the learning of phenomena and physical concepts of students with visual impairment in physics classes. It should be emphasized that when it comes to an education for all, it refers to the idea of giving students opportunities for access and permanence in school, with the same equality conditions, respecting their singularities. When addressing the issue of differences, it does not refer only to minorities or children with special needs. It is much broader, because all human beings are unique, therefore different from each other. Mobilization, a category of Relation with Knowledge (Charlot, 2000), was used as a theoretical contribution to the research. Having as a central question: What is the role of Goalball in the process of mobilizing the learning of students with visual impairment in teaching physics ?, sought to reflect on the involvement in an activity that creates meaning, desire and pleasure in the teaching and learning process of the students. There were two students, one male student (enrolled in the second year of high school) and the other female (enrolled in the third year of high school). It is a qualitative research of the participatory type, having as data collection instruments the observations of the classes, field diary, reorganized knowledge balance, semistructured interview and the organization of data based on the Descriptive analysis, Gil (2008). In this context, the research was exposed on the effects of Goalball in the physics classes in the students by a Mobilization, Searching, Remembering, Learning more easily, Reinforcing and Improving exercises and articles presented.
