Abstracts


The present study examined the effectiveness of ADDIE (Analysis, Design,
Development, Implementation and Evaluation) instructional strategy in reengineering
the senior secondary school system for students' sustainable
achievement in geometry. The study adopted quasi-experimental design of
pretest and posttest non-randomized control group. The population was the
entire senior secondary school one (SS1) in Ughelli Educational Zone of Delta
State. Stratified sampling technique was adopted to select four-intact classes
with 177 students assigned to treatment and control groups. The experimental
groups (90) were taught geometry using ADDIE instructional strategy to see its
cause effect on students achievement for academic sustainability; while, the
control groups (87) expository method. Two research questions and two null
hypotheses were answered and tested using mean sustainable achievement
scores and ANCOVA respectively. The instrument used for data collection was
Geometry Achievement Test (GAT) to measure students' achievement whether it
will be sustained with internal reliability index of 0.72 using Kuder-
Richardson's formula 20. Data analysis shown that students taught geometry
using ADDIE was re-engineered to achieve higher for sustainable instructional
development in the GAT (experimental groups) than the control groups. Also,
there is a significant difference between the mean scored of SS1 students who
were re-engineered in learning geometry with ADDIE strategy. Finally, female
students were more re-engineered with the use of ADDIE instructional strategy
applications in geometry learning than male students in the pretest and posttest
for sustainable achievement development.
