The aim of this qualitative study was to understand the process and mechanism of Oral Communication Apprehension (OCA) in English among Jordanian students inside and outside classroom settings. Nine students were purposively recruited from the Hashemite University (HU) in Jordan from different programs where the Medium of Instruction is English. Interviews were employed to explain the process and mechanism of the apprehensive behavior of the students’ oral communication scenarios. Findings revealed that the process of apprehensive behavior includes fear of negative evaluation, avoiding participation, avoiding coursework, anxiety, the missing opportunity for a job, limited social engagement, loss of confidence, and disorganized thinking patterns. Finally, pedagogical implications were suggested to reduce and alleviate the negative impacts of these psychological factors on the smoothness of oral communication and speaking fluency.
