Abstract :
The study determined the efficacy of origamibased instructional model (OBIM) on teaching proofs of
mensuration theorems: A panacea for college students’
understanding of mathematical theorem. Population of
the study was 2461 SSS III students in the public
secondary schools in Awgu Education Zone, Enugu
State, Nigeria. The study was guided by four research
questions and four null hypotheses. The hypotheses were
tested at 0.05 level of significance. Multi-stage sampling
technique was adopted, through which 149 subjects were
randomly sampled and used for the study. Mathematics
Achievement Test (MAT) instrument containing essay
items and developed by the researcher was used for data
collection. The MAT was subjected to lecturers in
mathematics Education and Measurement and
Evaluation areas for face validation and its reliability
formula yielded 0.79. The data collected with the MAT
were analyzed using mean and standard deviation (SD)
to answer the research questions while ANCOVA
statistic was used to analyze the hypotheses at 0.05 level
of significance. Results of the study revealed that OBIM
is effective in enhancing students’ understanding proofs
of mensuration theorems. Before treatment there was no
significant difference between experimental and control
groups (P .05) while after treatment there was
significant difference between the duo in which the
experimental group performed significantly higher than
their counterpart in control group. Moreso, before
treatment, there was significant mean difference in
performance between the males and females in
experimental group (P .05), while after treatment there
was no significant mean difference between the duo
which means that the use of OBIM is effective in
bridging the gap in gender inequality in mathematics
performance. It was recommended to teachers,
examination agencies (WAEC & NECO), authors of
maths textbooks and curriculum developers to
incorporate the use of OBIM in planning and execution
of mathematics instruction especially in teaching proofs
of mensuration theorems.
