A Contrastive Study of the Effectiveness of Comparative and Expository Advanced Organizers on the Achievement of 4th preparatory Students in English Grammar.

Abstract

The objective of this study is to investigate the differences in the effect of comparative and expository advanced organizers on the achievement of 4th preparatory students in English grammar. The study is limited to the 4th preparatory students in Ramadi schools for boys during the first term of the academic year 2012-2013. To achieve the purpose of the present study, it is hypothesized that there is no significant difference between the mean scores of the achievement of the first group who is given comparative advanced organizers and the second group who receives expository advanced organizers. To test the above hypothesis, a sample of 60 4th preparatory students from Al-Meethaq secondary school has been randomly chosen and distributed into two groups. The first group (30 students) has been exposed to comparative advanced organizers, while the second group (30 students) has been exposed to expository advanced organizers. Both assigned groups are equalized in terms of certain variables. The experiment lasted four weeks. During this period, the researcher himself taught the two groups to control the teacher variable. At the end of the experiment, students have been post-tested on the same subject matter which is constructed by the researcher. The data collected has been analysed by using t-test formula at 0.05 significance level. The findings reveal that there is a significant difference between the mean scores of the two groups in favour of the first group since its mean score is higher than that of the second group. On the basis of the findings, the study ends with a number of recommendations.
