Problem-based learning (PBL) is adopted in a unique One-Day One-Problem approach at Republic Polytechnic (RP), Singapore. The basis is that students learn best through engagement. This engagement at RP starts in response to a question or a problem, and continues with reasoning and understanding by students throughout the day. This paper presents the RP’s PBL practises in the School of Engineering in student engagement and daily reflection by citing one of the daily problem “Heart Rate Filters” in the module “Linear Circuits and Control” to show how students are engaged through problem trigger, simulation and class discussion throughout the learning process. This new form of engagement broadens the educational experience of engineering students and increases students’ interest in engineering education.
