    Focus Group Discussion in Developing Tanzania Secondary Schools e-Learning (TanSSe-L) System
    (2011-07) Kalinga, Ellen A.; Bagile, Burchard B.; trojer, Lena
    he knowledge on how ICT and its application can improve the social and economic lives of people generally is very limited in many communities of developing countries, Tanzania being among them. Although many people may have and be in contact with computers, does not mean that they really understand the impact that ICT if used effectively could have on improving performance. Developing computer systems for people to use, if lack of knowledge is not carefully considered, the motivation to use the system may be very minimal or completely absent. The emphasis on participatory action research methodology is that the introduction of technology into organizations accompanies learning and generates a specific form of knowledge. Finding appropriate system requirements depends on how close the developer is to the system users or stakeholders. Focus group discussion as inspired by the qualitative and participatory action research methodologies is the key to being close to users. This paper presents how focus group discussion was employed during developing Tanzania Secondary Schools e-Learning (TanSSe-L) system, specifically during requirement specification and analysis phase. It shows the importance of involving users while developing contextual information systems for a specific purpose. It also shows how secondary school stakeholders were made closer to the process of TanSSe-l System development, together with users’ response to reveal real problems in Tanzania education system. Keywords—Participatory Action Research Methodology, Focus Group Discussion, Requirement Specifications, TanSSe-L, ICT, e-Learning, Tanzania Secondary Schools, Triple Helix Model, Mode 2.

    An Interactive e-Learning Management System (e-LMS): A Solution to Tanzanian Secondary Schools' Education
    (2008-01) Kalinga, Ellen A.; Bagile, Burchard B.; Trojer, Lena
    Information and Communications Technologies (ICT) has been integrated in education in many developing and developed countries alike, but the use of ICT in Tanzanian schools is dismal. Many Tanzanian secondary schools have no computers. The few schools with computers use them primarily for secretarial services and computer literacy training. The Tanzanian education system at other levels like secondary school level has to undergo substantial transformation, underscored by the growing application of new information and communication technology. This paper presents the e-readiness survey result from secondary schools in Tanzania. The paper also suggests how Tanzania can make use of the few present ICT resources to support and improve teaching and learning functions to improve performance and acquisition of knowledge by using e-Learning Management System (e-LMS).

    MDA and Object Oriented System Analysis and Design Integration for TanSSe-L System Development
    (2011-07) Kalinga, Ellen A.; Bagile, Burchard B.
    In software development, a successful information system is subject to frequent evaluation and revision within the framework known as System Development Life Cycle (SDLC). SDLC is the basis for most software development methodologies, whether structured approach or object oriented approach. Tanzania Secondary Schools e-Learning (TanSSe-L) system is a customized learning management system (LMS) developed to enable ICT support in teaching and learning functions by allowing for the creation and storage of learning materials, making them available, easily accessed and sharable by students from different secondary schools in Tanzania. The development of the TanSSe-L system made use of software engineering discipline using Object-Oriented System Analysis and Design (OOSA&D) with Unified Modelling Language (UML) and Model Driven Architecture (MDA). Implementation made use of open source LMS through customization to help generate a timely solution to TanSSe-L system development. This paper presents how TanSSe-L system was developed through the integration of Object-Oriented System Analysis and Design approach and Model Driven Architecture to address the SLDC in a systemic way, the approach which led to the stage of customizing an open source LMS. It shows the importance of creating a base guide for customization.

    Research Methodologies Adopted in Developing TanSSe-L System
    (Department of Mechanical and Industrial Engineering, 2012-02-17) Kalinga, Ellen A.; Bagile, Burchard B.
    Tanzania Secondary Schools eLearning (TanSSe-L) system is one of the products of the ICT for eLearning research project conceived at the University of Dar es Salaam. The overall main objective of the e-learning project was to improve the quality of science education in secondary school in the rural areas of Tanzania by developing a tool to enable ICT support to rural secondary schools, by providing teaching materials, which are user friendly and facilitating self-learning and information sharing, starting with science and mathematics. This research work was based on three pillars; these are “establishment of suitable and effective connectivity and configuration”, development of a context centered platform which includes an e-learning management system using open source software” and “development of learning content materials for self-learning and sharing”. Development of a context centered platform which includes an e-learning management system using open source software was successfully developed and ended up having a TanSSe-L System, a Learning Management System (LMS) which allows for the creation and storage of learning materials, making them available, easily accessed and shareable among students from different secondary schools in Tanzania. TanSSe-L system was developed using a number of methodologies. This paper illustrates research methodologies used in developing a TanSSe-L system taking into consideration open source/low cost system, the issue of sustainability and the context of the application.

    Strategies for Developing e-LMS for Tanzania Secondary Schools
    (2011-10) Kalinga, Ellen A.; Bagile, Burchard B.; Trojer, Lena
    Tanzania secondary schools in rural areas are geographically and socially isolated, hence face a number of problems in getting learning materials resulting in poor performance in National examinations. E-learning as defined to be the use of information and communication technology (ICT) for supporting the educational processes has motivated Tanzania to apply ICT in its education system. There has been effort to improve secondary school education using ICT through several projects. ICT for e-learning to Tanzania rural secondary school is one of the research projects conceived by the University of Dar-es-Salaam through its College of Engineering and Technology. The main objective of the project is to develop a tool to enable ICT support rural secondary school. The project is comprehensive with a number of components, one being development of e-learning management system (e-LMS) for Tanzania secondary schools. This paper presents strategies of developing e-LMS. It shows the importance of integrating action research methodology with the modeling methods as presented by model driven architecture (MDA) and the usefulness of Unified Modeling Language (UML) on the issue of modeling. The benefit of MDA will go along with the development based on software development life cycle (SDLC) process, from analysis and requirement phase through design and implementation stages as employed by object oriented system analysis and design approach. The paper also explains the employment of open source code reuse from open source learning platforms for the context sensitive development of the e-LMS for Tanzania secondary schools.

    TanSSe-L System PIM Manual Transformation to Moodle as a TanSSe-L System Specific PIM
    (World Academy of Science, Engineering and Technology, 2012) Kalinga, Ellen A.; Bagile, Burchard B.
    Tanzania Secondary Schools e-Learning (TanSSe-L) system is a customized learning management system (LMS) developed to enable ICT support in teaching and learning functions. Methodologies involved in the development of TanSSe-L system are Object oriented system analysis and design with UML to create and model TanSSe-L system database structure in the form of a design class diagram, Model Driven Architecture (MDA) to provide a well-defined process in TanSSe-L system development, where MDA conceptual layers were integrated with system development life cycle and customization of open source learning management system which was used during implementation stage to create a timely functional TanSSe-L system. Before customization, a base for customization was prepared. This was the manual transformation from TanSSe-L system platform independent models (PIM) to TanSSe-L system specific PIM. This paper presents how Moodle open source LMS was analyzed and prepared to be the TanSSe-L system specific PIM as applied by MDA.
