This study investigated the effect of pictures and realia on academic performance of junior secondary school students in basic technology in Kaduna State, Nigeria. The study sought to determine the effect of pictures and realia on the academic performance of junior secondary school students in basic technology. This study was guided by research questions and null hypotheses. The study was delimited to only junior secondary school three (IlI) students of public secondary schools in Zonkwa and Kachia Educational Zones in Kaduna state.

Research questions were answered using mean, and standard deviation while, t-test statistics at P = 0.05 coefficient level of significance was used in testing the hypotheses. From the findings of the study, it was confirmed that, in teaching basic technology, the mean academic performance of students exposed to pictures and realia was higher than those taught the same concept using conventional (lecture method) The performance results obtained revealed that there is no significant difference in the performance of student exposed to pictures and realia materials in rural and urban areas but there was significant difference between the mean academic performance of male and female students.
