Increasing the Mathematical Literacy Based on the Problem Solving Teaching and Realistic Mathematics

The main of this research was to calculate the efficiency of 9th grade high school female students as well as educational process development to increase the math literacy.

This educational process was performed by integrating realistic mathematics education and the mathematical problem-solving process. The statistical population of the study consisted of 242 students which were divided into two groups; 122 students as the experimental group (A, B) and 122 students as the control group (C, D). The data analysis method was based on Data Envelopment Analysis (DEA). The output-oriented Charles, Cooper, and Rhodes (CCR) model was used for determining the efficiency of the students.

Each student was considered as a decision-making unit (DMU) in which inputs were mathematical pre-test scores and outputs were the mathematical post-test scores.

The results showed that students who were involved in problem-solving and realistic mathematics education were efficient.
