Framework for e-learning in higher institutions of learning in developing countries: a systematic review of literature
(International Journal of Science and Research (IJSR), 2017-12-12) Nkamwesiga, Lawrence
The concept of e-learning is a new phenomenon emerging in developing countries, an understanding of e-learning as a pedagogical process is crucial especially with the global proliferation of Information and Communication Technologies(ICTs). E-learning is an emerging pedagogical phenomenon that developing counties have not embraced fully due to its challenges associated with various implementation factors. A systematic review of 78 e-learning published research articles was conducted and gaps were analysed in the existing research and recommendations with a focus on developing countries. The purpose of the study was to establish evidence among researchers for e-learning challenges in developing countries with focus on Ugandan public universities. The synthesis of selected articles resulted into identification of recurring trends, crucial knowledge gaps, and a road map that shows the current state of e-learning in developing countries. The articles were taken from various African countries located in the sub-Saharan region that exhibited similar challenges of implementing e-learning in developing countries. Other developing countries in Europe, Middle East, south pacific, and Australia were included in the review. In an endeavour to produce unbiased results, the quality of the papers was critically observed by considering only peer reviewed articles published in recognized journals within the last 5 years. That would guide researchers, practitioners, implementers such as governments that would like to conduct research in the emerging e-learning as a crucial pedagogical process in the field of knowledge transfer and teaching.

(International Journal of Scientific Engineering and Science, 2018) Businge, Phelix Mbabazi; Guma, Ali; Andogah, Geoffrey; Nkamwesiga, Lawrence
Mobile devices are no longer playing the role of voice or short message communication but also in learning. These devices allow students to interact with educational content and learning can occur regardless of their location. It is therefore important to establish the factors hindering the use of Mobile devices for learning in Universities: A Case of Muni University. The study answered research questions such as; (a) what are the negative effects of using Mobile devices during lectures for other activities not related to the Lecture? (b) what are the reactions of lecturers towards the use of Mobile devices during lecture time? which factors are hindering the use of Mobile devices for learning? Quantitative design was employed using questionnaires containing a Five (5) Point Likert scale items ranging from strongly agree, agree, neutral, disagree, and strongly disagree and open-ended items were utilized in this study to obtain quantitative information to answer the research questions: A total population of 331 was considered and sample size of 181 was obtained using Krejcie and Morgan table. Stratified sampling was used to collect data from each stratum and data was analyzed using SPSS Version 20. The reliability of the data collected was tested using the Cronbach's reliability test coefficient were the overall value of all the options was on average 0.67 which was beyond recommended Cronbach’s Alpha coefficient values 0.6 for an instrument to be declared reliable. In terms of ascertaining the negative effects of using Mobile devices during lectures for other activities to the related Lecture, students agreed that it distract students' attention, disturb other students, disturbs the instructors and the course of the lesson and reflects disrespect for the instructor. The findings also agreed that the following were ranked among top five (5) factors hindering the use of Mobile devices for learning: Lack of mobile devices, Slow Speed of the mobile devices, Power problems, Network Connections Issues and Battery problem but disagreed that the course is not suited for mobile devices, lack of interest and complicated to use. This study recommended that mobile devices should be encouraged, allow students to use Mobile devices according to lesson’s topics since students disagreed that lack of interest is not hindering the use of mobile devices, discourage students from using Mobile devices in class for other activities not related to the topic and formulate the usability policy of mobile devices.
