We distributed 287 questionnaires and 261 (90.9%) students responded. There were 181 (69.3%) female students in the sample. Number of students who responded to the questionnaire from first year to final year as follows: 49 (18.8%), 55 (21.1%), 51 (19.5%), 59 (22.6%) and 47 (18.0%). 13 students did not respond to the question on awareness of CSF and we removed them from the analysis. We present the results of 248 respondents in the subsequent analysis.
Of 248 students, 140 indicated that they were aware of CSF indicating 56.5% (95%CI: 50.3% - 62.6%) CSF awareness among medical students at the Faculty of Medicine, University of Kelaniya. CSF awareness was higher in males (71.1%, 95%CI: 60.9% - 81.2%) compared to females (50.0%, 95%CI: 42.5% - 57.5%) (P=0.003). CSF awareness among the first year students (72.3%, 95%CI: 60.0 – 85.1%) was higher than the final year students (40.9%, 95%CI: 26.4 – 55.4%). Generalized linear model fitting showed a significant decrease in CSF awareness in the senior students (odds ratio = 0.74 (95%CI: 0.62 – 0.90) per each advancing batch).

Of 140 who were aware of CSF, 126 (90.0%) actually used these facilities. Hence, the CSF usage among all the students at the Faculty was 50.8% (95%CI: 44.4 - 57.2%). Male students showed a relatively higher CSF usage (62.5%, 95%CI: 51.9% - 73.1%) compared to female students (47.0%, 95% CI: 39.7% - 54.2%), although the difference was not significant. 63 (45.0%) students were aware of CSF before entering to the University (Table 1).
Among 140 of students who were aware of CSF, highest awareness was observed for Google Drive (85.0%) and 12.1% of students accessed it daily and 20.0% accessed it more than once a week. Second and third highest awareness were for Dropbox (73.6%) and OneDrive (42.1%), however more than 15% had never accessed them. Although students were aware of iCloud and Amazon, majority had never accessed them (Table 2).

Among the students who were aware of CSF, 79 (56.4%) had used cloud facility to transfer electronic files and 64 (45.7%) students used cloud storage to save educational materials. 36 (25.7%) had synchronized their files with CSF.
There was no difference in the Z score of G.C.E. A/L between students who were aware and not aware of CSF (median score: 1.96 (IQR: 1.92 – 2.00) versus 1.98 (IQR: 1.92 – 2.00) respectively, P= 0.251). Similarly, there was no difference in grade five scholarship results between students who were aware and not aware of cloud storages (median score: 151 (IQR: 140.0 – 162.0) versus 151.0 (IQR: 143.0 – 163.0) respectively, P =0.434).
We could not elicit a correlation between CSF awareness and the medical exam performances of students. Spearman’s rank correlation coefficient for continuous assessments as follows; continuous assessment 1 = -0.107 (P=0.107); continuous assessment 2 = -0.028 (P=0.701). For unit examinations it was; unit 1 = 0.032 (P=0.668); unit 2 = 0.129 (P=0.090); unit 3a = -0.001 (P=0.997); unit 3b = 0.084 (P=0.431); unit 3c = 0.144 (P=0.179); unit 4 = 0.146 (P=0.375); unit 5 = -0.188 (P=0.257).
Of 140 CSF aware students, 55 (39.3%) and 28 (20.0%) mentioned that they do not have adequate time and knowledge to use CSF respectively. Limiting factors for using CS included lack of accessibility 45(32.1%), concerns on security 37 (26.4%) and privacy 32 (22.9%). 109 (77.9%) students mentioned that cloud storage is useful for educational purposes and 19 (13.5%) students in view that CSF is little or no use for educational purpose.
Of total students, 35 (14.1%) student did not want to use CSF and 173 (69.8%) indicated that they would like to learn CSF as an effective tool for education. This included 72 (76.6%) of students who were not previously aware of CSF and 101 (84.9%) students who were already aware of CSF. 40 (16.1%) students did not wish to have a training on CSF and this included 22 (23.4%) students who were not aware of CSF and 18 (15.1%) who were aware of CSF.
