In that respect, whether course content is highly structured or not is one of the contributing factors that impact students’ interaction with the learning material (Chadwick and Ralston, 2010). One measurable output of such interactions is manifested in the form of tardiness in submitting assignments. A comparative study between a structured and a less-structured course at the post graduate (masters) level were used for this study. This study looks into students’ tardiness responses in submitting their Tutor-Marked Assignment (TMA) at Wawasan Open University in both a well-structured course and a less-structured course. The finding of this study shows that students are less participative and less tardy in a well structured course content compared to weak structured course content. Further exploration by the analysis of the five dimensions of the students’ interaction in the learning management system (LMS) concluded that in less-structured course content students tend to be high in procedural activities such as administrative issues. Survey questionnaires were distributed to students to obtain additional supporting data that are related to the structured nature of the courses which may affect their tardiness in the submission of the TMA. Implications of the findings were discussed with recommendations and for future research.
