This research aims to determine how effective it is to add some real-life examples into mathematics
curriculum teaching on academic achievement level in mathematics for preparatory school stage. Because
of the lack of real-life mathematics applications examples in some lessons in the preparatory schools'
mathematics curriculum and using the traditional method in teaching that led to only memorize the
mathematical concepts and arithmetic operations by heart without understanding. The researchers used
the analytical descriptive curriculum and the experimental curriculum with a quasi-experimental design
of one experimental group for the first and second preparatory grades. The research population was
selected from the students of the first and second grades of preparatory school at Martyr Mohamed Ahmed
Lotfy El Ashry Integrated Language School, Heliopolis Educational Zone in Cairo Governorate. Two
research samples were randomly selected from (99) students in the first preparatory grade, and (120)
students in the second preparatory grade, and each of them studied mathematics according to the
traditional method (control group) and using learning based on mathematics applications in life
(experimental group). Two tests will be given as part of the research for the first and second grades
preparatory students: pre-test on the control group and post-test on the experimental group. In this
research, we applied two achievement tests in mathematics to verify the effect of the proposed teaching
method. The research results explained that there is statistically significant difference in the mathematical
achievement level between the control and experimental groups for the first and second grades preparatory
students in favor of the experimental group. The research concludes that the learning based on real-life
applications of mathematics has a positive effect on their academic achievement level in mathematics for
the first and second grades preparatory students. The research recommends increasing awareness about
the importance of mathematics applications in real life and creating new learning methods to link between
the applications and our real life.
