These perspectives are illustrated in Figure \ref{539431},  as an average of the participants’ answers in the six IBT modules; with the per-module figures available as supplementary material
. Not surprisingly, participants were largely unfamiliar with the various modules,  especially the Linux module given their background (Supplementary_Questionnaire_follow_up or Supplementary_Table2_Graduates_demographics). There were (? %) comfortable with their former knowledge with the content while (? %) were uncomfortable. At this stage of the course, all participants have been involved in the survey (N=73, M=?, SD=?). During the first two modules many participants dropped out from the course (fig 1), mid-course and final surveys included fewer number of participants. As the course continued, their responses revealed that they were satisfied with the course content, (? %) were very comfortable with content whereas (? %) were neutral (N=?, M=?, SD=?). At the end of the course their satisfaction with course content reflected their expectations (? %) were very comfortable that the course met their expectations and (? %) were neutral (N=?, M=?, SD=?).
