    Enhancing learner- centered instruction through tutorial management using cloud computing
    (IGI Global, 2017) Thuku, John K.; Ondigi, S. R.; Maina, Elizaphan M.; Ayot, Henry O.
    Integration of modern technology in enhancing learner-centered approach to instruction is increasingly being encouraged in higher education. Cloud computing has enhanced the way data is shared and stored. Learning resources can be stored in cloud computers thus, enabling groups of students to collaborate and edit shared materials. In addition, it also provides a number of advantages such as reduce storage cost, enhanced security, accessibility of learning materials and easy communication. Tutorial classes can take advantage of cloud computing to have the tutorial learning resources stored in the cloud. This will allow learners to collaborate online and edit tutorial materials regardless of the physical location of the participants. This book chapter discusses how cloud computing technologies can be utilized in education sector and proposes a cloud computing model which can be incorporated in a tutorial class to improve learner-centered teaching pedagogies in a tutorial class

    Use of Intelligent Agents in Collaborative M-Learning: Case of Facilitating Group Learner Interactions
    (Modern Education and Computer Science Press, 2017) Njenga, Stephen T.; Oboko, Robert O.; Omwenga, Elijah I.; Maina, Elizaphan M.
    Intelligent agents have been used in collaborative learning. However, they are rarely used to facilitate group interactions in collaborative m-learning environments. In view of this, the paper discusses the use of intelligent agents in facilitating collaborative learning in mobile learning environments. The paper demonstrates how to design intelligent agents and integrate them in collaborative mobile learning environments to allow group learners to improve their levels of group knowledge construction. The design was implemented in a collaborative mobile learning system running on Modular Object-Oriented Dynamic Learning Environment (Moodle) platform. The application was used in some experiments to investigate the effects of those facilitated interactions on the level of group knowledge construction. The results showed improved levels of group knowledge construction in instances where the facilitations were enabled compared to where they were disabled. The paper concludes that the use of intelligent agents in facilitating learner group interactions in collaborative mobile learning environments improves the levels of group knowledge construction. For future work, the use of intelligent agents can be tested in other areas of group interactions to enhance group learning.

    Using Machine Learning Techniques to Support Group Formation in an Online Collaborative Learning Environment
    (Modern Education Computer Science Press, 2017) Maina, Elizaphan M.; Oboko, Robert O.; Waiganjo, Peter W.
    The current Learning Management Systems used in e-learning lack intelligent mechanisms which can be used by an instructor to group learners during an online group task based on the learners‟ collaboration competence level. In this paper, we discuss a novel approach for grouping students in an online learning group task based on individual learners‟ collaboration competence level. We demonstrate how it can be applied in a Learning Management System such as Moodle using forum data. To create the collaboration competence levels, two machine learning algorithms for clustering namely Skmeans and Expectation Maximization (EM) were applied to cluster data and generate clusters based on learner‟s collaboration competence. We develop an intelligent grouping algorithm which utilizes these machine learning generated clusters to form heterogeneous groups. These groups are automatically made available to the instructor who can proceed to assign them to group tasks. This approach has the advantage of dynamically changing the group membership based on learners‟ collaboration competence level.
