Abstract
The purpose of this study was to determine the extent of utilization of instructional materials by
agricultural science teachers for improved academic performance of students in secondary schools in Ebonyi State.
The study adopted a descriptive survey research design. Two research questions and two null hypotheses guided the
study to achieve the purpose of the study. The null hypotheses were tested at probability of 0.05 level of significance
and appropriate degree of freedom. The population of the study comprised 470 agricultural science teachers and
principals of secondary school. Purposive sampling was used in sampling 140 principals and 249 teachers. The
sample size was 389. It was this population that was used for the study. Structured questionnaire was used for data
collection made up of 52 items. The instrument was validated by three experts and Cronbach Alpha Statistics was
used to determine the internal consistency of the instrument and a coefficient of 0.72 was obtained. A total of 371
copies of questionnaire were retrieved and analysed using weighted mean and standard deviation to answer the
research questions and t-test was used to test the null hypotheses. The findings of the study revealed among others that
agricultural science teachers select and utilize instructional materials such as improvised materials, audio visual aids,
computers, pictures, concrete materials, scientific laboratories, fish pond, farm visits, livestock pen etc to a low extent
in Ebonyi State. The null hypotheses tested showed that there was no significant difference between the mean ratings
of principals and agricultural science teachers with respect to the extent teachers utilize instructional materials in
Ebonyi State. Based on the findings, it was recommended that teachers should select appropriate instructional
materials, principals should adequately supervise agricultural science teachers to ensure that they select and utilize
instructional materials and the use of the identified instructional materials should be emphasised by the ministry of
education during workshops and seminar to teachers.
