Abstract
The main objective of the study was to investigate the role of models on students’
conceptual understanding of geometry in Addis Zemen higher education preparatory
secondary school. Specifically, the study examined students’ understanding on their
ability to identify the effect and contribution of models on the students’ geometric
concept understanding, providing different type of instructional material and teaching
methods to the students in order to understand geometric concepts simply. The study
employed quasi-experimental design. The data were collected from 92 students and
grouped in to two one treated group the other the control group. The data were collected
using test in the actual classroom situation, and analyzed using a t-test and ANOVA test
were used for data analysis. Then the result indicated that the use of models in teaching
geometry has significance in geometry classes. Hence, the study implied that
teachers/curriculum expert’s taught to aware of the students, concept understanding to
diagnose and involve models approach in the teaching and learning process of geometry.
Finally, the study suggested that the concepts of geometry are abstract in nature and it
requires more visualization tools to the students’ geometrical concept understanding and
for spatial thinking
