By combining their learning and solutions, this group has designed multiple plausible solutions (several potential synthetic routes). Finally, they identified and selected the simplest synthetic route, and the target product was successfully synthesized. This specific design of the PBL which combines proble m breakdown and the jigsaw technique enables the production of multiple solutions, primarily indicative of the possibility to the generation of creative solutions. Moreover, this group expressed high satisfaction with their training and performance via an obligatorily survey carried out by their project coordinator at the École Technique Supérieure de Chimie de l'Ouest. As a result, our lab has formalized an agreement with the project coordinator to host intern students regularly each year.
