Effects of Screen Size in Mobile Learning Over Time

Two experiments were conducted in order to investigate the effects of screen-size (3.5" vs. 7" vs. 10.1") on efficiency of mobile learning (m-learning) over time (immediate vs. delayed). Experiment 1 (N=141) revealed that students who took a mobile learning course on a large screen scored higher on a test administered immediately after the completion of the course. In Experiment 2 (N=111), another test was conducted two months after the first test. The Result indicated that the screen size did not make a significant difference on m-learning students over time. In detailed, test scores of students who took the course on a small screen were not relatively affected by the time of administering the test, whereas test scores of students with a large screen mobile device were decreased over time. Implications of notable findings are discussed. Also, limitations and future studies are examined.
