The study was led by six research questions, and six hypotheses were examined at a significance level of 0.05. The quasi-experimental design was used, notably the non-equivalent control group design for the pretest and posttest. 4,873 senior secondary school students in the Nnewi Education Zone of the state of Anambra make up the study’s population. In the study, 2.73 percent of the population was used. A sample of 133 Nnewi Education Zone SS2 computer science students was used. The Computer Studies Department and one knowledgeable computer studies teacher from Nnewi. Kudder-Richardson Formula 20 was used to determine the instrument’s reliability. The CSAT was used as a pretest and posttest to gather data. Three weeks following the post test, the retention test was given.The results demonstrated that a lesson followed by animated media education greatly improved students’ computer science performance. When compared to the traditional approach, only tutorials considerably increased students’ retention, however, this improvement was not significant when compared to animated media. The study concluded that tutorials are successful at raising students’ achievement and retention. The use of animated material in the classroom has been shown to improve student achievement.
