The study investigated the extent of usage of web-based applications (WBA) for instructional delivery by lecturers in tertiary institutions in Rivers State, revealing that both male and female lecturers reported low usage of both restricted and non-restricted access applications. The research employed a descriptive survey design with a sample of 140 lecturers, analyzing data through mean, standard deviation, and t-tests, concluding no significant gender differences in usage. Recommendations include enhancing access to WBA, training lecturers on effective use, and improving infrastructure for technology integration in education.
