THE EFFECT OF USING MENTAL COMPUTATION IN IMPROVING MATHEMATICAL PROBLEM - SOLVING ABILITY AMONG STUDENTS

The present study aimed to identify the effect of mental computation in improving the ability of university undergraduates in mathematical problem - solving. To achieve this aim, the quasi - experimental approach was used. Participants were (80) preparatory year students at Najran University in Saudi Arabia who were distributed into two main groups using the simple random sampling. One of these groups (N = 40) was assigned as the experimental group and was taught via the use of mental computation method. The second group (N = 40) was assigned as the control group and studied through the use of traditional methods. Mathematical problem - solving ability pre-test and posttest were applied to both groups. Findings showed that there were statistically significant differences between the two groups with regard to the mathematical problem- solving posttest in favor of the experimental group.
