Abstract:Higher learning institutions nowadays operate in a more complex and competitive due to a high demand from prospective students and an emerging increase of universities both public and private. Management of Universities face challenges and concerns of predicting students' academic performance in to put mechanisms in place prior enough for their improvement. This research aims at employing Decision tree and K-means data mining algorithms to model an approach to predict the performance of students in advance so as to devise mechanisms of alleviating student dropout rates and improve on performance. In Kenya for example, there has been witnessed an increase student enrolling in universities since the Government started free primary education. Therefore the Government expects an increased workforce of professionals from these institutions without compromising quality so as to achieve its millennium development and vision 2030. Backlog of students not finishing their studies in stipulated time due to poor performance is another issue that can be addressed from the results of this research since predicting student performance in advance will enable University management to devise ways of assisting weak students and even make more decisions on how to select students for particular courses. Previous studies have been done Educational Data Mining mostly focusing on factors affecting students' performance and also used different algorithms in predicting students' performance. In all these researches, accuracy of prediction is key and what researchers look forward to try and improve.
The research intended to develop a framework for improving the usability of Learning Management Systems by integrating pedagogical agent. The study adopted usability heuristics as the key factors for enhancing the usability of an LMS through a conversational pedagogical agent. The first objective explored various techniques available for enhancing the usability of the LMS. The techniques includes Learnability, efficiency, and satisfaction are but a few techniques used to measure usability of a web-based system. The second objective examined a variety of ways the pedagogical agent can improve the usability of the LMS. The research recognized that a pedagogical agent could improve the usability of an LMS by making studying more interesting and increasing student to instructor interaction to support active learning. The third objective was for the designing of a suitable framework for improving the usability of an LMS. The fourth objective intended to evaluate the impact of the computer-based pedagogical agent in the LMS. The research established that the conversational pedagogical agent increased human to computer interaction, makes learning more effective and enjoyable and supports self-paced active learning. An experimental research design was adopted in carrying out the research. A conversational pedagogical agent (Melsyanne) was deployed as a prototype to improve the effective use of an LMS. The target population comprised of 3 HODs, 12 Instructors and 82 Students from three randomly selected higher learning institutions within Nakuru Municipality. Data was collected using questionnaires and analyzed through frequencies and percentages using SPSS. The results were presented using tables, column graphs and pie-charts generated by MS Excel application software. The findings constitute the knowledge pool, from which future research can borrow and add in their research study.
Kenya's public sector is at a crossroads today in facing the challenges of institutional change and the impact of new technologies. The public sector can, and will play a much stronger role in implementing all the government plans. The emerging ICT technology can create solid improvement in offering better services to all nations. This can enable the citizens of the countries to access e-services from the governments based on their trust to the systems. In Kenya things have not been as planned as majority of the people don't trust e-government services.There are many challenges facing its implementation which now remains as a dream, despite the government efforts. The paper raises a lot of concern especially on the trust of the citizens to egovernment services being offered and the ICT awareness of the citizens too. The work highlights what the government has done to address the issue. The proposed solutions will help as e-government, and ICT investment has consumed a huge part of the national budget in recent years. The paper addresses how trust influences the change of attitude towards government by employees and the citizens.
