That MLA conformed with Heuristic guidelines Students generally had positive perceptions towards TheĪnalysis was carried out with the aid of SPSS The hypothesis was tested using t-test statistics. The data collected were collated andĪnalysed using descriptive statistics such as mean, standard deviation and inter rater agreement while Validated and tested for reliability by giving it toĮxperts and students and subjecting them toĪnalysis using inter rater reliability and CronbachĪlpha from which 0.81 and 0.75 were arrived at The instruments for both experts and students were Two instruments (Experts’ Usability Evaluation Questionnaire and Students’ Usability Evaluation Questionnaire) were used to gather information from the two sets of respondents.
