“…To develop the process of thinking in a learning process, it is necessary to have a model or learning theory that supports the thinking framework. One model that can be used to guide students to think creatively, critically, and at high ordered thinking is Problem Based Learning (PBL).Problem Based Learning is a learning model that is based on the many problems that require authentic inquiry, that is, investigations that require real resolution of real problems (Nurhidayati et al, 2018;Phungsuk et al, 2017;Abdullah et al, 2015;Ari & Katrancı, 2014). Through the Problem Based Learning model, students are trained to work together as a group to find out problem solving and most importantly they can improve their ability to solve problems and make conclusions as well as decisions (Han et al, 2016;Haji et al, 2015;Jalani & Sern, 2015) PBL can influence and enhance students' critical thinking (Joshi et al, 2020;Andersen et al, 2019).…”
