The target population for this study consisted of all the
second year students in public Junior Secondary Schools (JSS)
in Calabar metropolis of Cross River State, Nigeria. There are
50 junior secondary schools in the metropolis. JSS year two
students were chosen for the study because the researchers
believed that:
1) The students have some level of maturity and confidence
required to participate in the study having been previously
taught mathematics at the JSS year one.
2) The students were not being prepared for any impending
and immediate external examination that could distract them
from full participation in the study.
3) The plane shape and Angle topics used as intervention in
the study are contained in the JSS year two mathematics
curriculum.
