Effect of Demonstration Method of Teaching on Students’ Achievement in Agricultural Science

Abstract

The study investigated the effect of demonstration method of teaching on students’ achievement in agricultural science in secondary school in Kogi East Education Zone of Kogi State. Two research questions and one hypothesis guided the study. The study employed a quasi-experimental research design. The population for the study was 18225 senior secondary two (SSII) students in 195 secondary schools. Six (6) secondary schools were used for the study using purposive random sampling technique. In each of the school selected, two intact classes of the SSII were used. Four hundred and eighty (480) students in the twelve intact classes constituted the sample for the study. The instrument for data collection was a 30-item ‘Agricultural Science Achievement Test’ (ASAT). Using Kuder Richardson 20 (K-R20) formula, a reliability index of 0.78 was obtained. Research questions 1 and 2 and the only hypothesis were answered using mean, standard deviation and analysis of covariance (ANCOVA) at 0.05 level of significance. The result of study revealed that demonstration method had significant effect on students’ achievement than those taught with the conventional lecture method. Useful recommendations such as: efforts should be made by teachers to thoroughly integrating demonstration method in the teaching of agricultural science in secondary schools; efforts should be intensified by teachers to aggressively adopt demonstration method in teaching agricultural science in all classes at the secondary school level were proffered.
