theabsence of student mobility, it is not just a short-term solution to the disruption campuses facetoday. COIL should be part of a comprehensive plan to advance internationalization foruniversities. Virtual engagement programs such as COIL and study abroad are not "zero-sum"alternatives, rather they complement one another and provide a more rich and seamlessexperience for students. The expansion of traditional study abroad alone will not meet the needsof engineering students. In fact, since COIL is not location-specific, students and faculty at 2multiple sites are able to participate in a single COIL course, something not possible for moststudy abroad

We discussreflections from the faculty members about the value and challenges of designing a dynamicsOEMP. We then describe how initial observational feedback was collected from undergraduatesat multiple institutions who assessed the new OEMPs from a student perspective. Next, we presentthe OEMP assignments we created. The paper concludes by describing our plan for

In the fall of 2020, therecitation course was not offered to students and thus will serve as a baseline for student gradecomparison.

Because wind energy is sustainable, clean, and does produce greenhouseemissions and U.
