(Faculty of Computing and Technology, University of Kelaniya, Sri Lanka, 2021) Nadesana, Nixsala; Wijayarathna, Gamini
The education in the world was affected by the COVID-19 pandemic, especially higher educational institute process functionality was interrupted by stopping the physical class rooms. As per the COVID-19 effect the large number of higher educational institutes move to the online education like universities in Sri Lanka [1]. Higher educational institutes have taken their course orientation, lectures, registration, examination and assignment submissions or thesis submissions through online platform. The students and lecturers having issues to get the physical materials like reference books through online. Those problems are most identified in science course providing departments. Because the students in science stream have to prepare for their practical work. But they have a struggle to go to their institute and do the practical activities in pandemic situation. Therefore, the practical integrated online education accompanied LMS will help the university students. This paper analyses numerous approaches taken by higher educational sectors to deliver teaching, laboratory practices and semester examinations in consideration of the COVID-19 pandemic, while also considering the potential effects on the student learning experience and lecturers convenient. The mission of Sri Lankan higher educational sectors during the pandemic is offering accessible quality online education delivery, research and innovation in order to produce young leaders in the relevant fields to suit the needs by conducting collaborative learning and examination process without postponing the educational process of the students by charging the current pandemic impact by COVID-19.

Technologies brought in tools and techniques into education, resulting in the development of new concepts such as E-Learning. E-Learning is a broad term that refers to distance education or distance learning via technology. Following the coronavirus disease outbreak (COVID-19), school closures and a sudden shift to online learning have increased the risk of poor children falling further behind in their studies. Not all children have the necessary facilities or access to the internet during extended curfews, lockdowns, or when schools are closed indefinitely. The broadband internet facilities are also limited in remote areas, and teachers and students find it difficult to conduct and access real-time educational sessions. Therefore, sending recorded lessons will be the only solution for them. However, this should be done under minimum internet facilities. Sri Lanka is a country which is a high mobile penetration as 141.7% in 2021. Thus, this paper proposes a mesh networkbased model for distance learning, especially where there is a lack of internet access. Mesh networking is a way to send and receive data between all nodes. It makes continuous connections through paths by moving from one node to another until the destination is reached. These mesh network nodes are all connected in a fully connected network. Wireless Mesh Network solution is a new, enhanced WLAN architecture that redefines the boundaries of WLAN technology, enabling wireless connectivity for end-users. In this model, we assume the maximum distance between one node to another node is 150 feet because the full Wi-Fi range is 150 feet. A unique mobile app developed for this purpose will connect the users. That mobile app has user activities as well as background activities. The students can request lessons through the app. For that, students need to select grades and lessons first. Then the app will automatically request a lesson chosen from the nearest node. After receiving data, it will save in the app storage folder. Mesh network needs connectivity with other nodes even users don't use the app. Therefore, app always runs background activities to make connectivity. Also, if another user request data from the network, the app automatically checks app storage to find that data itself. If information is available on storage, it will send to the requested node. Only teachers can publish lessons on the network. The teacher can upload lessons to relevant categories on their app storage folder. The administrator is the only person who can add new users or content categories to the app. This model will help the students and teachers to easily share the lessons in the areas where internet connection is limited and ensure the access to the educational materials continuously.

UML System Model to Implement Authentic Learning in the 21st Century
(Faculty of Computing and Technology (FCT), University of Kelaniya, Sri Lanka, 2021) Wickramasinghe, Manuja; Wijayarathna, Gamini; Ferenando, Kasun
The Pandemic situation demanded all universities to transform towards online teaching and learning as an alternative to face-to-face study through Technology Enabled Learning (TEL). In most developing countries, universities use Learning Management Systems (LMS) such as Moodle and Blackboard to facilitate online education. The LMS is used mainly to facilitate staff, administration, and students sharing module outlines, specifications, lecture schedules, lesson plans, assignment generation and submission, announcements, and generating assessment reports. However, it has been observed that many inefficiencies exist in the teaching and learning approaches as there is less focus on learner autonomy. Dynamic changes in the world and drastic transformations demand continuous learning and innovative thinking. Authentic learning is an approach that focuses on real-world situations to gain new knowledge and skills in a context rather than listening to lectures and memorizing information. In authentication learning, enabling collaborative learning has been observed as a practical approach to developing critical thinking, reflective thinking, and enhancing creativity. Sri Lankan culture is inherited with authentic learning as our cultural events, traditions, and values encourage living in harmony and learning from each other. This paper proposes a new system as a web portal to ensure that the learner can effectively gain the required knowledge, skills, and attitudes to face complex realworld situations, thus arriving at practical solutions to overcome contemporary issues. The proposed system focuses particularly on distance learning programs, as those could be advanced by the adoption of a model that can be used to guide the design of online learning environments focused on elements of authentic learning. In addition to presenting the authentic task model and its theoretical functionalities, the authors have implanted Bloom's Taxonomy Theory to ensure the quality and effectiveness of the system model. Researchers have incorporated use case diagrams and activity diagrams to exemplify the UML model.
