Abstract
This study aims to determine the improvement of mathematical problem solving ability and self efficacy of students. The population of the study was the 4th semester Mechanical Engineering students of the 2020 academic year at the University of Muhammadiyah Tangerang who enrolled in Engineering Mathematics courses on the topic of Differential Equations. Two classes of the population were analysed as the sample of the study by treating one class as the control group and the other as the experimental one. The experimental group applied the Problem Based Learning method while the control group applied conventional learning. The data was collected by analysing the Problem Based Learning student worksheets on the Differential Equation topic in order to evaluate mathematical problem solving ability and self efficacy of the students. The statistical method used was the mean rank and the Mann Whitney U test. The results showed that the mean rank of students in the experimental class obtained an average score of 31.89 which was higher than students in the control class with an average score of 13.11. In addition, the results of Mann Whitney U test, with U was equal to 35,500 and p was smaller than 0.05, showed that the Problem Based Learning method had an effect on mathematical problem solving ability and self efficacy of students.
