Data analysis
Statistical analyzes were conducted to analyze the data and find answers
to the research questions. The significance value was taken as p
<0.05 The English academic achievement of the students was
obtained from the English achievement test. Pre-test success scores of
the experimental and control groups were considered as covariant. The
difference between the post-test success scores of the experimental and
control groups was analyzed by covariance analysis, and the difference
between pre-test and post-test achievement scores were analyzed by
dependent groups t-test. Before the analysis of covariance, the
assumptions of covariance analysis were examined. Firstly, pre-test
scores, which were treated as covariants, were measured before
implementation. Pre-tests are valid and reliable tests which are
prepared by Ministry of National Education, Assessment and Evaluation
General Directorate. Since there is only one covariant in this study, it
is not tested whether there is a relationship between covariates.
Graphical analysis was performed to determine whether there is linearity
between covariant and dependent variable.
