Abstract
Problem-based learning (PBL) is a student-centred approach to learning in which students work in groups to solve open-ended problems in real-life scenarios. Literature precedents indicate that PBL enables students to develop practical chemistry skills, resulting in increased participation and engagement. Additionally, empirical evidence supports the acquisition of soft skills through PBL. This poster presents the design of a PBL case study in sustainable chemistry, focusing on the pressing global challenge of plastic recycling. Currently, around 400 million tonnes of plastic are produced annually, with less than 10 per cent being recycled. The case study places students in the role of chemists and materials scientists working in a start-up company dedicated to developing plastic recycling processes. Their team is tasked with optimizing a method for converting waste polystyrene into a sulfonated functionalized polymer. To support their work, students have access to recorded lectures throughout the activity. They are organized into teams and given three weeks to achieve the following objectives: optimizing the experimental method, characterizing the new functionalized materials, developing an application for the new materials, and securing funding from a group of investors. Tutors trained in PBL delivery oversee the entire activity, which is assessed through a combination of report submissions, oral presentations, and peer assessment. This PBL case study design serves as a model for laboratory-based chemistry modules where this approach is not widely utilized.
