Polyhedron International Journal in Mathematics Education (PIJME) journal aims to stimulate discussions at all levels of mathematics education through disseminating significant and innovative scholarly studies that are of value to the international research communities. The journal welcomes articles focusing on all aspects of mathematics education including empirical, theoretical, methodological, and philosophical works that have a perspective wider than local or national interest. PIJME publishes only original scholarly works. Manuscripts that are indeed a derivative or replication/duplication (if there is not clear reason, justification) of previous work are not accepted and will not be published in PIJME. Please do not submit the same manuscript simultaneously or separately to PIJME with another journal. In such cases the responsibility solely rests with the author(s).

Abstract

This study was motivated by the low mathematics learning outcomes and self-confidence of eleventh grade students. Most students have not reached the minimum completion limit of 75. In addition, the learning process is still teacher-centered so that students tend to feel bored, lack focus, and lack confidence in solving mathematical problems. This study aims to determine the effect of the Problem-Solving learning model on self-confidence and mathematics learning outcomes. The design of this study is a static group comparison design. Participants were selected using a random sampling technique, with class XI F2 as the control class and class XI F3 as the experimental class. The research instruments used were a self-confidence questionnaire and a mathematics learning outcome test. Data were analyzed using a t-test with the help of SPSS software at a significance level of 0.05. The results showed that the Problem-Solving learning model had a significant effect on students’ self-confidence, as indicated by a significance value of 0.004 <0.05. In addition, the Problem-Solving learning model also had a significant effect on students’ mathematics learning outcomes with a significance value of 0.015 <0.05. Thus, it can be concluded that the application of the Problem-Solving learning model is able to improve self-confidence and mathematics learning outcomes. As a recommendation, the Problem-Solving learning approach is suggested as one of the strategic choices in mathematics education to increase students’ self-confidence and learning achievements, and can be considered for application to various materials and different levels of education.
