This study examined the effect of mobile phone application on academic performance of Adult literacy learners in
Ondo State, Nigeria. Gender difference in the performance of adult learners taught with mobile phone application was
examined. The quasi-experiment pretest-posttest experimental control group research design was employed. A sample of
sixty (60) adult learners selected using purposive sampling technique participated in the study. The researchers developed
the mobile phone application and the test instrument used to collect the data. Validity and reliability was carried out by
experts and ANCOVA statistics was used for data analysis. The result of the findings revealed that the adult learners
exposed to the use of mobile phone application performed better than those taught without the mobile phone application.
Also, findings also revealed that gender had no significant effect on the academic performance using mobile phone
application for learning basic literacy and numeracy skills. It was recommended that instructors/facilitators should be
encouraged to make use of mobile phone application in teaching/learning process. Also, seminars, workshops and
conferences should be organized for both the instructors and adult learners to expose them to the skills and competencies
required for using mobile phone application for teaching and learning towards enhancing the delivery of Adult literacy
education in Nigeria.
