The study
investigated the effects of peer assessment on students’ academic achievement
in junior secondary school computer science. The study employed
quasi-experimental design. The study was conducted on two secondary schools. In
one of the schools intact class of Jss II was assign to the treatment group
while in the other secondary school the intact class Jss II were assigned to
the control group. The treatment group was taught concepts in measures of
central tendency in Microsoft excel software using a peer assessment
instructional package (PAIP) while the control group was taught concepts in
measures of central tendency in Microsoft excel software using conventional
teaching package. Simple random sampling technique was adopted in choosing the
two secondary schools out of which 120 junior secondary school II students were
selected from the sample schools. Three research questions and three null
hypotheses guided the study. Computer achievement test (CAT) was use to collect
data for the study. The data was analyzed using mean, standard, deviation and
analysis of covariance (ANCOVA). The result revealed that peer assessment which
is a method of assessment where by learners are allowed to assess their peers
and give feedback based on a given rule had significant effect on students’
academic achievements in computer science. The study also revealed that the
difference in the mean achievement of male and female students taught using
peer assessment method is not statistically significant. The study recommended
that peer assessment strategy should be used by teachers in the teaching and
assessment of student in computer science subject.
