ELearning for Persons with Visual Disabilities: Case of Low Vision
(handbook-research-educational-technology-integration, 2015-01-02) Wambua, Ruth N.; Oboko, Robert
ABSTRACT This chapter discusses an eLearning platform that is usable by persons with low vision. To start with, such a platform is achieved by incorporating technological advances such as: use of text with the highest possible contrast; use of varying font size; among other customized Human Computer Interaction (HCI) effects. Moreover, use of complicated, decorative or cursive fonts should be avoided, as well as italic text and capital letters, which can be difficult for users with reading impairments. In summary, this chapter supports the fact that eLearning is possible for persons with low vision, provided that all the necessary technological advances have been considered.
Implications Of Internet Of Things (IoT) On The Education For Students With Disabilities: A Systematic Literature Review
(International Journal of Research Publications, 2022-06-08) Wambua, Ruth N.; Oduorb, Collins
Abstract The world today has greatly been influenced by the advancements in technology, which has resulted to changes across all sectors of life, which includes the education sector. Moreover, the COVID-19 pandemic as of March 2020 resulted to more ICT integration in most sectors including education, leveraging on emerging technologies like the Internet of Things (IoT), Mircea et al., 2021. IoT refers to the network of interconnected people and devices to the world wide web (www) powered by the internet and is already in use in Education where learning and academic institutions are now incorporating IoT in educational activities, considering the ubiquitous nature of the IoT devices, Kassab et al., 2020a. However, despite the many technological advances, the adoption, and the impact of IoT in education is still in its infancy, Dai et al., 2021. According to the United Nations sustainable goals of 2015, quality education is both Inclusive and equitable, and promotes lifelong learning. Therefore, regardless of the adopted technologies, quality education should be facilitated to all people within the population, Kayhan et al., 2015a. Considering the world population of 15% that is of people living with disabilities according to World Health Organization, this paper therefore is a systematic review of literature for the period 2010 to 2021, on the implications of Internet of Things (IoTs) on the Education for students with disabilities, to highlight benefits, challenges, adopted scenarios, technologies, as well as gaps and notable areas for further research.
Internet of Things security and privacy in Higher Education Institutions in Developing Countries
(Research Journal of Education, Teaching and Curriculum Studies, 2024-03-17) Wambua, Ruth N.
Abstract Technological breakthroughs like the Internet of Things (IoT) technology have tremendously impacted today's world and have led to changes in many spheres of life, including education. With the pervasiveness of IoT devices, learning and academic institutions are already integrating IoT into educational activities. Nonetheless, despite the numerous technological advancements and the demand for high-quality education for everyone, IoT's adoption and impact on education are still in their infancy. On the other hand, with the number of connected items having reached billions and still growing, there is cause for concern regarding the Internet of Things' potential for serious privacy violations, considering it is one of the most potent technologies for creating, modifying, and sharing data. Therefore, to emphasise the thematic areas and prospects for additional research related to the security and privacy of the Internet of Things (IoT) and within Higher Education Institutions (HEIs), this study explores the security and privacy of IoT in the context of HEIs within developing countries
Leveraging Blockchain Technology In Curbing Forgeries On Final Graduation Certificates
(International Journal of Research Publications, 2023-01-05) Wambua, Ruth N.
Abstract Counterfeit academic certificates and qualifications are a common problem in recruitment. Not only do employers face the challenge of sorting through all candidate applications, they also need to check that the certificates presented are authentic (Tavares Serranito et al., 2020). Further, there is need to curb the rampant degree forgeries and ensure degree certificate traceability is to the right graduating institution. It is also important to ensure accountability of all degree certificate holders and that their awarded certificates would be traced back and verified at their graduating universities (Filipe & Dias, 2018). Robotic cameras are used for scanning, and Arduino Uno device for storing the certificate data. Blockchain is then used to control the access of the encrypted certificate data generated in the chain of blocks, through a smart contract. Any request for viewing the certificate is granted by a smart contract. If request is granted, the hash address is used to retrieve the certificate. With the implementation of blockchain technology in universities, the issue of certificate forgery could be minimised. Certificate forgery is a disadvantage to the society in that holders of forged papers attain offices on assumed merit – “forged” merit. Therefore, leveraging on the strengths of the blockchain technology of smart contracts, cryptocurrency and tokenizing, immutable distributed ledger, cryptographic hashing, and digital signature (Gourisetti et al., 2020), certificate forgery is addressed by implementing blockchain in universities. Graduation certificates and transcripts contain information confidential to an individual and which should not be easily accessible to others. Individual attributes once defined, and the approved certificate is awarded to the graduand, the record remains unaltered with blockchain technology..
Mapping the Landscape: A Comprehensive Review of Digital Health Models for Equitable Access to Universal Health Coverage
(The University Journal, 2024-06-24) Wambua, Ruth N.
Abstract Digital health is the appropriate application of technology to enhance the health sector. With Universal Health Coverage (UHC), insufficient money is not a major hindrance to receiving the full range of high-quality healthcare services if and when needed. Strategies, models, and frameworks continue to be formulated to guide operations, as well as in the regulation of healthcare. This study provides a thorough analysis of digital health models for equitable access to UHC by highlighting key factors of these models while identifying and analyzing knowledge gaps. Considering UHC and the aspect of inclusivity as espoused in the Sustainable Development Goal 3 (SDG3), which speaks of health for all in a population, this study explores models that cover a general population and were designed with equity as a key component. The study methodology is a scoping review that uses a manual search of digital libraries and repositories, employing tailored search terms. From the results, though models exist that address equity, more work is required to formulate generalizable digital health models for equitable access to UHC, and majorly for developing economies. Moreover, it is a call to consistently adapt models that meet the target needs of a population at any given time.
