This study examines how learners present their knowledge in the e-learning environment. This study adopted concept-mapping technology to observe fifty-four learners. There are two findings: first, the learners frequently employed relationships and examples, which assisted them in making connections between new and old knowledge throughout the learning process, thereby allowing them to acquire knowledge; however, they seldom used hierarchies and cross-links. Second, their knowledge presentation styles remained fixed while engaging in various tasks ranging in from the simple to the complex. Based on our findings, for instructors, it is crucial to consider the style of knowledge presentations made by learners because these presentations can the effectiveness of information technology on learning performance. For system designers, the systems should be designed to provide greater flexibility by increasing the opportunities for learner autonomy. Moreover, this study would encourage learners to apply critical thinking skills when reflecting upon their current knowledge.
