Measuring Usability Compliance of an E-learning System: The Users’ Perspective, Nigeria
This study assessed usability compliance of Opón-Ìmò Technology Enhanced Learning System (OTELS), Nigeria. Specifically, the study investigated: students’ satisfaction with the OTELS; its efficiency; retentiveness; learnability and capacity to reduce errors. Being a survey study, samples were drawn from six secondary schools across the three Senatorial districts of Osun state, Nigeria. 701 students were purposively selected as sampled for the study. A researcher-constructed questionnaire: Usability Compliant Questionnaire was used for data collection. The instrument was administered on 40 selected students outside the sample location through test-retest strategy; it yielded reliability value of 0.87 through Pearsons Product Moment Correlation statistics. Data were analysed with frequency counts and percentages to answer research questions one to five. Results revealed that 70% of respondents expressed satisfaction with the OTELS; 73% found the OTELS efficient; 68% found it retentive; 76% found the OTELS learnable; and 59% agreed that the OTELS is capable of reducing errors when in use.The study concluded that the OTELS is usable for learning among secondary school students in the state. It was recommended among others that Osun state government may constantly update the learning system to sustain its use among secondary school students.
