Planning effective HCI to enhance access to educational applications

Information and communications technologies (ICT) are widely believed to offer new options for Web-mediated courseware design. Multimedia and online courseware development accentuates a belief that highly graphical (or visual) delivery media will meet the individualised instructional requirements of diverse student cohorts. While most electronic courseware may allow the user to proceed at their own pace, two assumptions are commonly made by courseware designers. Firstly, to facilitate learning, all users are assumed capable of assimilating the graphical content with their current experiential knowledge. There is little or no consideration of different cognitive styles. Understanding learner attributes is essential to increasing accessibility to computerised information. Secondly, learning is assumed rather than demonstrated. To deal with this issue, data analysis techniques can be used to differentiate between what an individual knows from what they do not. This paper presents two research projects that demonstrate the importance of awareness for the human-dimension of human-computer interaction (HCI) in designing effective online experiential learning for special education

ICT Integrations in TVET: Is it up to Expectations?

AbstractIn today's world where information and communication technology is playing a major role in people's daily lives, how a student learns is dependent on how the student reacts to the sophisticated system offered by these technologies. Thus, it is not surprising that online learning is accepted as an important tool in the general education sector. However its adoption in Technical and Vocational Education and Training (TVET) is yet to reach the equivalence of the general education sector. With the availability of state of the art online learning technology, there is greater opportunity for acquiring the technology that can support TVET practices. The aim of this paper is to discuss the trend of ICT integration in teaching and learning in TVET based on a systematic review of ICT integration in post-secondary TVET. The focus is mainly on the “what’ and “how” aspects of ICT integration in TVET. The literature reviewed indicates that while ICT integration can be aimed at the learning goals in the three domains, the affective, cognitive and psychomotor domain; its effectiveness is more noted where learning goals are of the cognitive domains. More effective integration is also indicated where the blended mode is adopted as compared to the fully ICT mediated mode. Lessons learnt in light of these findings are discussed for future ICT integration in TVET

HCI expertise needed! Personalisation and feedback optimisation in online education

Two key challenges in education relate to how traditional educational providers can personalise online provisions to the students’ skill level, optimise the use of tools and increase both the generation and utilisation of feedback (in terms of timing, content, and subsequent use by students). The application of traditional programmes in the online setting is often complicated by the legacy of traditional universities infrastructures, knowledge bases (or lack thereof in the human-computer-interaction/HCI realm), and pedagogical priorities. It is here that HCI experts (designers and researchers) can have real-world impact in line with macro-HCI, while also being able to test new innovations in collaboration with educators (e.g., the practitioners in such education settings). In this note, we make a case that the HCI community is in a situation where it can make a significant contribution to traditional providers in two prospective areas: personalisation, feedback generation and increased feedback utilisation

Teaching and Technology Techniques for Teachers In Online Learning Environments

When developing and delivering instruction, whether online or not, the use of technology is secondary to well-designed learning goals and objectives. What distinguishes online instruction and technology in the classroom from entertainment or recreation is the conceptual development of teaching techniques based on solid learning theories. This paper proposes a conceptual framework for implementing teaching and technology techniques for online learning environments

Implementation, use and analysis of open source learning management system “Moodle” and e-learning for the deaf in Jordan

When learning mathematics, deaf children of primary school age experience difficulties due to their disability. In Jordan, little research has been undertaken to understand the problems facing deaf children and their teachers. Frequently, children are educated in special schools for the deaf; the majority of deaf children tend not to be integrated into mainstream education although efforts are made to incorporate them into the system. Teachers in the main stream education system rarely have knowledge and experience to enable deaf students to reach their full potential. The methodological approach used in this research is a mixed one consisting of action research and Human Computer interaction (HCI) research. The target group was deaf children aged nine years (at the third grade) and their teachers in Jordanian schools. Mathematics was chosen as the main focus of this study because it is a universal subject with its own concepts and rules and at this level the teachers in the school have sufficient knowledge and experience to teach mathematics topics competently. In order to obtain a better understanding of the problems faced by teachers and the deaf children in learning mathematics, semi-structured interviews were undertaken and questionnaires distributed to teachers. The main aim at that stage of research was to explore the current use and status of the e-learning environment and LMS within the Jordanian schools for the deaf in Jordan. In later stages of this research, semi-structured interviews and questionnaires were used again to ascertain the effectiveness, usability and readiness of the adopted e-learning environment “Moodle. Finally pre-tests and post-tests used to assess the effectiveness of the e-learning environment and LMS. It is important to note that it was not intended to work with the children directly but were used as test subjects. Based on the requirements and recommendations of the teachers of the deaf, a key requirements scheme was developed. Four open source e-learning environments and LMS evaluated against the developed key requirements. The evaluation was based on a software engineering approache. The outcome of that evaluation was the adoption of an open source e-learning environment and LMS called “Moodle”. Moodle was presented to the teachers for the purpose of testing it. It was found it is the most suitable e-learning environment and LMS to be adapted for use by deaf children in Jordan based on the teachers requirements. Then Moodle was presented to the deaf children’s to use during this research. After use, the activities of the deaf and their teachers were used and analysed in terms of Human Computer Interaction (HCI) analysis. The analysis includes the readiness, usability, user satisfaction, ease of use, learnability, outcome/future use, content, collaboration & communication tools and functionality

User experience of academic lecturing staff in the use of a learning management system tool : a case study at an open distance learning institution in South Africa

The teaching model in Open Distance Learning is moving towards fully integrated information and communication technology applications, therefore, academic lecturers need to have a strong comfort level with the use of technology tools. The academic lecturers are qualified and experienced subject matter experts but this does not translate to having the necessary technical competencies to do online teaching. They consequently could experience feelings of incompetency to facilitate courseware on a technology platform. The study identified the factors that influence the user experience when using a Learning Management System (LMS) in an academic institution. The research design comprises a convergent, parallel design mixed-method case study. A literature review was conducted to abstract the factors that influence the user experience into a conceptual framework. An expert review was conducted to validate the conceptual framework and then a questionnaire-driven survey was performed. The quantitative analysis of the survey results revealed that eight of the nine factors proposed in the conceptual framework do have an influence on the perceived user experience of the academic when using the LMS. The qualitative analysis revealed that all nine of the identified factors do have an influence on the perceived user experience of the academic when using the LMS. The contribution of this study is to present a conceptual framework of the factors that influence the user experience of the academic when using an LMS to improve our understanding of the experience of the academic and the practical challenges involved for academics that have to facilitate learning in an online environment The findings should be of interest to developers of LMSs and to institutions in support and training of academics that have to use the LMS.School of ComputingM.

Are Language learning websites special? Towards a research agenda for discipline-specific usability

With the intention of defining an initial research agenda for discipline-specific factors in the usability of e-learning websites, this paper focuses on the example of foreign language learning. First, general notions and concepts of usability are analyzed, and the term 'pedagogical usability' is proposed as a means of focusing on the close relationship between usability and pedagogical design. Then, to address the key issue of whether there are aspects of pedagogical usability that are discipline-specific, the paper examines how language learning and teaching, in particular Technology Enhanced Language Learning (TELL), has approached usability when developing technology-enhanced learning materials. Three elements of a research agenda are identified: pedagogical usability, intercultural usability and website evaluation. In conclusion, it is suggested that just as language learning websites may require a discipline-specific approach, so in other disciplines pedagogical usability may also need to be considered in relation to the specific requirements of the discipline, and that a debate around these issues is timely
