We outline a new tool that can promote coherence within and across higher education mathematics courses by focusing on problem-solving: the Mathematical Problem-Solving Pipeline or MPSP. The MPSP can be used for teaching mathematics and mathematical reasoning authentically. It can be used across courses to develop problem solving skills that can be generalized beyond the course and topic. It has a specific focus on documentation and communication that lets students leverage skills they grow, and use, in other courses or fields. The MPSP can be used in singleton (service) courses, throughout a curriculum, and/or within a capstone experience.
