This study investigated the effect of teacher’s quality and quantity on student’s academic performance in Ovia North East secondary schools in Edo state, Nigeria. Prior to this study, the researcher observed that poor performance of students in chemistry was alarming. This was attributed to many factors among which are inadequate numbers of chemistry teachers to teach the subject, teacher’s qualifications, professionalism, teacher’s gender among other variables.
The design used for the study was survey research design. The population and sample of the study consists of all the secondary school Chemistry teachers in Ovia North East of Edo State. There was no sampling technique because the entire population was taken as sample. Three (3) standard instruments which are questionnaire, checklist and profoma were used to gather data for the study. There was no need to carry out validity and reliability because the instruments were standard instruments. The data obtained were analyzed using descriptive statistic such as percentages, Anova statistic and t- test. The hypotheses were tested at 0.05 level of significance.
The findings of the study revealed that there were not enough chemistry teachers in the studied Local Government Area; it further revealed that there was a significant difference between teacher’s qualification, teacher’s professionalism and teacher’s gender on student’s academic performance. It was therefore recommended that government should urgently embark on the process of employing more qualified Chemistry teachers, in addition, only qualified chemistry teachers should be allowed to teach chemistry at the senior secondary school level. While the holders of Nigeria Certificate in Education (NCE) should be allowed to proceed in their education either through part-time or study leave likewise teachers without teaching qualification should be advice to pursue their Post Graduate Diploma in Education (PGDE).This may improve their teaching method in order to improve the performance of students in chemistry. Lastly, female teachers should be encouraged to find Chemistry teaching as an interesting task.
