Table 2. Progress made by the experimental and control groups
The data collected suggests the following experiment results:
First of all, the experimental (CLIL) groups have made greater progress than the
control groups: the experimental groups’ results in the case of Academic Reading test
exceeded the control groups’ results by 20%; in the case of the Academic Writing test,
by 24%; and, finally, in the case of the Use of English test, by 16%.
Secondly, when we compared the results of both experimental groups (group A and
group B) the data indicated that both groups have made comparable progress (see
Table 3).
