Many authentic BME projects require system integration. This year, before the start of the open-ended Capstone projects, three connected modules were used as an initiative to practice systems integration and thus promote readiness. To this aim, a Do-It-Yourself spectrophotometer/colorimeter was used as the interconnecting theme. In the first two hands-on modules, teams developed electrical circuits and mechanical hardware to implement, test, and assess their unique designs. The third theoretical module focused on design impact analysis related to ABET student learning outcome two. In this activity, each student team proposed multiple design ideas for a pulse oximeter. Together, these modules over four weeks enabled students to integrate and consider a system as a whole. Throughout the intervention, instructors provided formative feedback. End-of-module presentations, written reports, and a practical exam were used as part of the modules. While the efficacy of the intervention was not formally assessed, an informal, anonymous survey was provided to the students. Overall, the intervention was well-received by the students and improved their abilities to approach system integration. The presented teaching tip shares the resources and summarizes the students' informal reflections.
