Abstract
Double Loop Problem Solving (DLPS) is one of the learning models that purpose to improve mathematical problem-solving skill. As a DLPS learning model, the constructivism approach is one of the learning approaches that can be applied to improving students mathematical problem-solving skill. The purpose of this study was to determine the effect of applying the DLPS learning model with constructive approaches to students mathematical problem-solving skill. To realize this goal, quasi-experiments was done in 3 South Tambun Senior High School. Two classes were selected using the Cluster Random Sampling method. The DLPS learning model with the constructivism approach is applied to the first class, while conventional learning models are applied to others. Students mathematical problem-solving skill are measured through tests made based on indicators of problem-solving skill. Before starting the program, the initial skill of students is calculated based on the results of the PAS (Final Evaluation). The program was carried out eight meetings, during which the eighth meeting was conducted post-test. The hypothesis was tested using an independent sample t-test with a significant probability of 0.05. The results of the study show that there is a positive influence on the application of the DLPS learning model with the constructivism approach to students mathematical problem-solving skill (p-value <0.05). The results showed that the average test results of students mathematical problem-solving skill with the DLPS learning model with the constructivism approach were higher than those of students with conventional learning models. This research is in line with the research conducted by (1) Jatisunda M. Gilar (2017) the constructivism approach has a positive influence on students mathematical problem-solving skill. (2) Pratama (2018) DLPS learning model has a positive influence on students mathematical problem-solving skill. This manuscript is based on the research that we have done.
