This study was conducted in order to reveal the usage profiles and perceptions of AsynchronousDiscussion Forums (ADFs) of 126 computer engineering students from the ComputerEngineering Department in a university in Turkey. By using a mixed methods researchdesign both quantitative and qualitative data were collected and analyzed. Research findingsindicatedthat the ADFs were frequently and effectively used by computer engineeringstudents as a learning instrument. Another finding was that discussions in the ADFs were in the form of question-answer and resulted in important learningoutcomes especially in eliminating the problems encountered by the students.
