EFFECTS OF COMPUTER ASSISTED INSTRUCTIONAL SOFTWARE ON SENIOR SECONDARY SCHOOL STUDENTS' ACHIEVEMENT AND RETENTION IN TRIGONOMETRY IN ISEYIN LOCAL GOVERNMENT AREA

The Study examined the effect of Computer Assisted Information (CAI) software known as Frizbi Mathematics 4 software on Senior Secondary School students achievement and retention in Trigonometry in Iseyin Local Government Area. The population of the study comprises all the SS2 students in secondary schools in Iseyin Local Government Area. Purposive Sampling Technique was used to select three schools that have computer laboratory, Therefore, Simple random Sampling technique was used to select sample size of One hundred and twenty which was divided into experimental and control group. Students in the experimental group were taught Trigonometry using Frizbi Mathematics 4 software while those in the control group were taught Trigonometry with the traditional method of teaching. The period of the instruction lasted for two weeks. Thereafter the research instrument tagged Trigonometry Achievement Retention Test was administered on both groups. The score obtained were analyzed using mean, standard deviation and t-test at 0.05 level of significance. The result shows that there exists a significant difference in the mean achievement and retention scores of the experimental and the control groups. The observed difference was in favour of the experimental group. The study further revealed that there is no significant difference between the mean achievement and retention scores of male and female students who were exposed to CAI software irrespective of genders, this implies that CAI is not gender bias. The study therefore concludes that CAI-Fribzi Mathematics 4 software has positives, significant effects on senior secondary students achievement and retention in Trigonometry. Hence, it recommends among other things that Mathematics teachers be encouraged to use the CAI Frizbi Mathematics 4 software in the teaching of Trigonometry in Secondary School.
