Management of assessment data in open and distance learning (odl) institutions in Nigeria
The study examined the management of assessment data in ODL institutions in Nigeria. Specifically, it investigated how the assessment data generated for the post-graduate ODL students is being managed (in terms of organization, storage and analysis for effective decision making). The assessment data is a Big data considering the large number of students that register for programs/courses in ODL institution (the volume); the variety of courses offered; the velocity or increasing rate at which the data is being generated and the veracity or differing quality of data sources. All these characteristics of assessment data pose challenges to the data, it’s processing and management. Thus, the study also identified the challenges of managing the assessment data (Big Data) that is generated for the students. The study was carried out in Nigeria, using the National Open University of Nigeria (NOUN). Exploratory research design was adopted for the study. The population of the study was the post-graduate students and Heads of Departments in eight faculties of NOUN and the directorates of Management Information System and Examinations and Assessment of the University. Two research questions guided the study. The instrument for data collection was oral interview and NOUN News reports. The data collected was analyzed qualitatively and the information deduced from the interview and news report was used to support the discussion. The findings revealed that the big data is being properly managed by NOUN.
