ABSTRACT
Massive Open Online Course (MOOC) is one of the famous online courses in the
current educational systems. Most of the universities are using MOOC’s all over the
world. Therefore, students follow MOOC courses to study subjects to enhance their
knowledge, skills in their chosen field. Even though there is a huge student’s base for
MOOC courses there are prevailing problems as well. They are less percentage of course
completion rate and difficulty to follow the course contents as scheduled by the
universities. Currently, it is very hard to find analytics tool to analyze students’ data
which is generated due to the usage of numerous MOOC’s activities such as assignment
submission, group activities and forum post etc. to identify the students’ failure rates.
Therefore, this research mainly focused on developing a tool to analyze MOOC data
effectively. MOOC data set of Harvard/MIT, which includes 600000 records and 36
attributes, were selected for this research. Graph analytics was implemented with the
Hadoop framework and hue was used for the graph visualization. Multi-dimensional
cubes were created to analyze the data. Numbers of graph patterns were realized to
identify the students based on region, subject and duration of the courses. Data mining
technique was used to develop a machine learning model to predict the pass rate
accuracy. Logistic regression model was given the highest accuracy with 96.08. The
research output of Graph analytics and data analytics patterns would be utilized in
future for effective functioning of MOOC systems.
