Research Question 1
Will there be a significant difference in achievement on a test comprised of "drill- and- practice" items between students learning individually and students learning collaboratively?
The mean of the posttest scores for the participants in the group that studied collaboratively (13.56) was slightly higher than the group that studied individually (11.89). A t- test on the data did not show a significant difference between the two groups. The result is given in Table 1. An analysis of covariance procedure yielded a F-value that was not statistically significant (F=1.91, p>0.05).
