Many higher educational institutions have adopted Learning Management Systems. Blackboard, characterized as one of the technological educational systems, is one of the leading and extensive Learning Management Systems adopted by most universities. However, literature showed that a missing link appears between Blackboard adoption and Blackboard poor usage in teaching and learning. Therefore, this study aims to gauge the perceptions of students toward using Blackboard Collaborate in learning English as a Foreign Language academic writing. Online survey was conducted and distributed to 248 respondents. This study is quantitative in nature, employing Technology Acceptance Model theory to check Learning Management System acceptance at Saudi Electronic University in Saudi Arabia. The findings showed that all the constructs were relatively strong and had positive relationships; they were correlated with each other and the whole six hypotheses were supported as well. In this paper, the proposed model indicates that Attitude toward Use is the strongest predictor of Behaviour Intention. This study offers implications for further studies.
