Adopting Distance Learning Approaches to Deliver Online Creative Arts Education During the COVID-19 Pandemic
No full textThe focus of this paper is the offering of the Bachelor of Performing Arts (External) General Degree in distance learning mode using a Learning Management System (LMS) which assisted the rapid transfer process of all undergraduate courses at the University of Visual and Performing Arts (UVPA) to online delivery mode during the COVID-19 pandemic. This research is presented as a case study, and a questionnaire was used to collect data from 81 participants. It was evident that most students have accessed learning material multiple times via the LMS and have used pre-recorded instructions/audio-visuals as educational aids effectively. Having flexible access to learning material has facilitated self-learning and contributed to improving their skills as students had opportunities to repeatedly watch demonstrations at preferred times. Results indicated that 78.1% have accessed learning materials for 10–15 times, which strongly emphasizes the students’ preference for independent learning including the effectiveness of the design and inclusion of video material. The survey indicated that 93% of participants would prefer using video instructional materials for also learning other subjects and these materials improved their skills in dancing. The prior experiences and practices of educators and students led to a smooth transition to fully online delivery of all courses offered at the UVPA demonstrating the applicability of distance learning methods to online delivery. Modern theories of education and learner behavior suggest that the use of audio-visuals as educational aids increase the capacity of knowledge internalization and this assertion was confirmed by this study

Promoting learner-centeredness in creative arts education: the use of flipped classroom approach and technology-integrated blended learning
No full textSince 2011, the University of Visual and Performing Arts has been providing distance learning opportunities for students via e-learning through the Centre for Open and Distance Learning (CODL). The UVPA is the only university in Sri Lanka that provides degree programs exclusively in Creative Arts exclusively and these art forms are traditionally taught face-to-face (f2f) in authentic learning environments employing hands-on activities thus remote teaching using electronic platforms has been a challenging experience for teachers and learners. However, research indicates that the e-learning methods can enhance the effectiveness of learning as they provide flexible access and individualised learning opportunities to students, especially when pre-recorded material is posted in the Learning Management System (LMS) used by the CODL for these (External) Degree and extension courses. Responding to the Covid-19 pandemic lockdown, the UVPA offered all courses and programs online from November 2020, and this prior experience and knowledge of teaching online assisted the expeditious transition
Knowledge management framework for mobile telecommunication sector in Sri Lanka
No full textSri Lankan mobile telecommunication industry is a fiercely competitive market space where five key mobile service companies operate. Most operators provide their services island wide; therefore the coverage footprint is no longer a differentiating factor. On the other hand, knowledge is a tool, which companies can use to provide a better service quality, which is now in demand with customers.
Due to globalization and increasing opportunities for individuals, companies face a challenge to retain best employees within the organization. Now the focus has shifted to keep the knowledge within the organization even with the movement of skilled labor. Therefore, knowledge management systems are necessary than ever before, but a most suitable knowledge management framework is yet to be identified.
The objective of this study was to determine a most appropriate Knowledge Management Framework for Mobile telecommunication sector in Sri Lanka. To realize this goal, initially, a literature survey was performed. The Author analyzed various knowledge management models available and best global practices of knowledge management aspects. It revealed six key concept variables, i.e. socialization, externalization, combination, internalization, knowledge sharing culture, and leadership. Next, an online survey tested these concepts to find the importance and current practices in the mobile telecommunication industry in Sri Lanka. This study identified that all the six concept variables were relevant to Sri Lankan context, while externalization, combination, and internalization practices were at a lower level. Finally, a knowledge management framework suitable for mobile telecommunication industry in Sri Lanka was developed
Viability of lean manufacturing tools and techniques in the apparel industry in Sri Lanka
No full textLean Manufacturing can be considered as a business strategy which was originated and developed in Japan. It tries to identify waste and eliminate it. Thus it leads to improvement in productivity and quality and companies can achieve a competitive advantage over others. Starting from the automotive industry, it has rapidly spread into many other industrial sectors and there has been significant development and localization of the Lean Manufacturing concept in both developed and developing countries worldwide. In implementing this concept there are tools and techniques developed by Toyota which can be used effectively.
The initial step of this research is to study about the Lean Manufacturing. It starts by looking at how Lean Manufacturing first began. Then it seeks to identify the core principles, tools and techniques of Lean Manufacturing. After that an extensive literature review was carried out to find successful Lean tools and techniques currently use in worldwide. The next step is to identify tools which are used frequently and which are not used. There will be a study to find out the barriers of implementing other tools and techniques
After studying the global scenario the next step is to look at the Sri Lankan context. Sri Lankan industries, especially apparel sector have attempted to implement this, but a little research work is carried out in regarding its suitability. This research is an attempt to identify a suitable Lean model for the apparel industry in Sri Lanka using real world data, structured surveys, observations, and on site interviews. Also the study will reveal period of Lean implementation, suitable implementation methods, order of implementation, tools which are avoided, sustainability of different tools, challenges faced, ways of overcoming challenges and benefits achieved after applying Lean Manufacturing concepts in the apparel sector of Sri Lanka.
The findings states Lean Manufacturing can be applied to mass production apparel industries and has made positive impacts. As implementation of Lean concepts is still in development stage, the full benefit is not yet achieved. However current situation suggests that the industry can go forward with Lean. In this research the author has come up with a model which can be used to implement Lean in a systematic manner and each manufacturer must develop their own Lean system through training, experiments and kaizen.
Originality of the research: The research builds up a Lean Model which is not yet developed for the apparel sector in Sri Lanka. It can be further modified to suit the global apparel industry and other industries as well
A Novel Robust Geolocation-Based Multi-Factor Authentication Method for Securing ATM Payment Transactions
No full textCredit/debit cards are a ubiquitous form of payment at present. They offer a number of advantages over cash, including convenience, security, and fraud protection. In contrast, the inherent vulnerabilities of credit/debit cards and transaction methods have led many payment institutions to focus on strengthening the security of these electronic payment methods. Also, the increasing number of electronic payment transactions around the world have led to a corresponding increase in the amount of money lost due to fraud and cybercrime. This loss of money has a significant impact on businesses and consumers, and it necessitates the development of rigid and robust security designs for securing underlying electronic transaction methods. In this regard, this research introduces a novel geolocation-based multi-factor authentication method for improving the security of electronic payment transactions, especially ATM transactions. The proposed method leverages geolocation to verify the user’s identity and prevent fraudulent transactions. In addition, this research also proposes a novel design approach for further controlling the ownership of transactions in a convenient way (e.g., allowing users to deactivate/reactivate authentication at any time, block the card in case it is stolen or lost, and set up a withdrawal limit). Overall, this approach does not require any major modifications to the existing banking infrastructure, which would be an ideal solution for securing ATM transactions around the world
