Is project-based learning integrated to STEM can improve creativity and problem-solving skills in mathematics learning?

Creativity and Problem Solving are the two crucial skills for 21st-century learning. To practice these skills, it is necessary to have a learning method that can increase creativity and problem-solving abilities in learning mathematics, namely PJBL-STEM. This article aims to examine the PJBL-STEM theory more deeply, especially those related to creativity and problem-solving abilities in mathematics learning. The method used is a literature review. The results obtained are that PjBL-STEM has the potential to optimize creativity and problem solving through giving open-ended problems. The writer's contribution is to deepen the understanding of the concept of PjBL -STEM for teachers and students so that teachers can improve students' creativity and problem-solving abilities in learning mathematics.
