Cover Story: The COVID-19 pandemic has presented substantial challenges to higher education, especially experiment-based STEM courses. In this study, we reported a virtual problem-based learning (PBL) activity to enrich the Instrumental Chemistry teaching curriculum. The project required students to propose solutions to real-case scenarios using specific analytical instruments in different categories. The outcomes of this study affirm that the PBL research project significantly enhanced students' proficiency in diverse scientific research and experimental skills. View this paper
