Developing Complexity Science-Problem Based Learning Model to Enhance Conceptual Mastery

Implementing a proper learning model during the post COVID-19 pandemic is fundamental for learning quality enhancement, specifically for students' conceptual mastery. The research aims to develop a Complexity Science-Problem Based Learning (CS-PBL) model assisted by the "Sistem Informasi Pengelola Pembelajaran" (SIPEJAR) e-learning platform that is valid, practical, and effective to enhance students' conceptual mastery during the post COVID-19 pandemic. The research and development model were adapted from Plomp & Nieven consisted of three phases: preliminary research, prototyping phase, and assessment phase. The first phase research result was that the learning process in during COVID-19 pandemic was less interactive, which led to less effective learning. The students' score on conceptual mastery was in the poor category. The second phase resulted in a book of CS-PBL model assisted by SIPEJAR and supporting instruments considered valid by three experts. The third phase result was that the CSPBL model assisted by SIPEJAR was considered practical in the learning process implementation. The CS-PBL model can enhance students' conceptual mastery where the N-gain was sufficiently effective. It is concluded that the CS-PBL model assisted by SIPEJAR was considered valid, practical, and effective to enhance students' conceptual mastery during the post COVID-19 pandemic.
