%0 Journal Article %T The Impact of Supplementary On-Line Resources on Academic Performance: A Study of First-Year University Students Studying Economics %A Elisa Birch %A Andrew Williams %J International Education Studies %D 2013 %I %R 10.5539/ies.v6n1p95 %X This paper examines the impact of supplementary web-based materials on students¡¯ academic performance in a first-year economics unit at university. In particular, the paper considers the impact of students¡¯ usage of the unit¡¯s webpage, voluntary on-line discussion board, voluntary on-line quizzes and voluntary on-line homework questions on their final mark in the first-year economics unit. It finds that students who make use of on-line materials perform better in the unit than students who do not, holding prior academic ability constant. The paper also finds that students¡¯ usage of on-line supplementary materials does not vary according to their academic ability. %U http://www.ccsenet.org/journal/index.php/ies/article/view/20869
