Project-Based Instruction (PBI) is the capstone course in the sequence of required education courses and is required before TNT students can do their apprentice teaching. In Classroom Interactions, students gain experience designing a sequence of several lessons that they teach to a high school class. In PBI, students design full units of connected lessons, a skill that will be required in apprentice teaching. PBI also provides students with the experience of managing lessons and students outside of a classroom in a field setting. The name of the course belies the fact that it emphasizes more than just project-based instruction. PBI emphasizes choosing from a variety of appropriate teaching styles, dependent on the type of material and the learning objectives; project-based instruction is not the only alternative. Students are required to incorporate various technologies into the units they plan.
