Abstract


Teaching practice is a mandatory requirement for graduation from College of Education in Nigeria. The objectives of the study was to find out the variance components for persons, occasions and person crossed with raters and residual, generalizability coefficient and the dependability index (indices). Two facets crossed with raters design was used.1, 393 students participated in the study. Scores of students’ in 2016/2017 teaching practice course obtained was data used. The data obtained were analyzed using variance components (VARCOMP), relative error variance, absolute error variance, and indices statistics. The findings of the study were that: variance accounted for in 2016/2017 students’ teaching practice by the following components were, persons (o2p) = 0.02 occasions (020) = 0.03 interaction of persons with occasions (02p0) = 0.05 and residual (02prqe) = 0.15, generalizability coefficient 0.84 was obtained and dependability index of 0.74 was also obtained for students’ scores in 2016/2017 teaching practice course respectively. The study concluded that the indices of students’ scores in 2016/2017 teaching practice were high or acceptable. This implied that the quality of students’ scores in teaching practice course is standard. The study recommended that the sixteen weeks slated for teaching practice should be maintained.
