This is a longitudinal study to investigate whether there is a correlation between the methods for completion of homework and the incentive levels with academic achievement. The method adopted in this study is the t-test statistical analysis to assess the relationship between the use of compulsory homework on achievement and the influence of intervening and moderating variables. The findings are as follows -- Cohort 1 which completed homework in the traditional pen and paper style (with a mean of 13.278) performed better than the Cohort 2 which completed homework online They also performed better than Cohort 2 which completed homework online (with a mean of 11.851). Cohort 3 that had no incentive and subsequently no compulsion to do the homework (with a mean of 11.851) performed better than Cohort 2 which completed homework online (with a mean of 9.658).
