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.
