Effect of Linear-Power-Point Instruction on Performance in Trigonometry Concepts among Senior Secondary School Mathematics Students in Katsina State, Nigeria

This study aimed to assess effect of Linear-Power-Point Instruction on Performance in Trigonometry concepts among senior secondary school Mathematics students in Katsina State, Nigeria. The research design of this study is quasi-experimental design. The population is made up of 69932 (41196 males and 28736 females) senior secondary school class two (SS II) students during the 2023/2024 academic session in Katsina state. A sample of 199 SSII students (Male 123 and Female 76) was chosen through a multistage sampling technique. One instrument, the Trigonometry Performance Test used to gather data for the study. This instrument was validated by experts and after pilot testing, demonstrated high reliability with estimates of 0.83. Descriptive statistics of mean and standard deviation was utilized to answer the research questions, while t-test was employed to test the hypotheses. The findings of the study indicated that there was a statistically significant difference in the mean performance scores of the students taught using Linear PowerPoint group and non-digital technology groups. Based on these findings, it was recommended that Linear PowerPoint Instructional packages should be encouraged in schools for teaching Trigonometry.
