Effect of Triangle Solver Game on Secondary School Students' Achievement and Retention in Trigonometry in Ogoja Education Zone in Cross River State

The study investigated the effect of triangle solver game on secondary school students’ academic achievement and retention in trigonometry in Ogoja Education Zone. Four research questions guided the study, and four null hypotheses were tested at 0.05 level of significance. The design of the study was quasi-experimental design. The specific design was the pretest-posttest. Non-equivalent control group design. The study was carried out among secondary schools in Ogoja Education Zone of Cross River State. The population for the study consisted of 1,945 mathematics students in the Senior Secondary two (SSS 2) in the study area. The sample size 389 drawn from Ogoja Local Government Area. The instrument for data collection was Trigonometry Achievement Test (TAT). TAT was face validated by three experts in the Department of Curriculum and Instructional Technology in University of Cross River State. The reliability co-efficient of the instrument was determined to be 0.98 Using Kuder-Richardson formula ( k – R 20). The subjects were pretested before the treated and the posttest was administered after the treatment, while the achievement test was administered two weeks after the end of the treatments. The data collected were analyzed using mean and standard deviation and Analysis of Covariance (ANCOVA). The findings of the study showed that students who were instructed and taught using Trigonometry with triangle solver game achieved higher and retained more than those taught with conventional method. It was also discovered that no particular gender was favored more by the treatment. Based on the findings of the study. It was recommended that secondary school mathematics teachers should be given training on Triangle solver game so that they can use it while teaching. Also, workshops and seminars should be organize for serving teachers so as to acquaint them with the skill of triangle solver game.
