The primary aim of the study is to identify whether there are any significant mean differences among
demographic variables such as gender, age group, faculty, teaching language and experience of university
teachers employed at the University of Jaffna, Sri Lanka on the usage of electronic information resources (EIR).
The study employs independent samples t- test and one-way ANOVA (f-test) to test the operational hypotheses.
The survey method used in this study is a questionnaire and a total of 75 usable responses were obtained using
stratified random sampling technique. The t-test revealed a statistically significant difference between the mean
number of usage of electronic information resources and gender (t = 5.099, p < 0.05) with the highest mean
value of male university teachers. According to the f-test, there are significant mean differences among age
group, teaching language and experiences of teachers on the usage of electronic information resources, whereas
mean usage of electronic information resources do not differ significantly among five different faculties (F =
2.075, p > 0.05). This study would hopefully benefit to the academicians, researchers, policy makers, and
practitioners of Sri Lanka as well as other countries.
