At a minimum, you should still include these components at the end of your podcast:
Individual Credits. If you are working as a group, you should include each individual and their respective role in the production. If you partnered with any individuals or organizations outside the class at any stage of the process you should also include their name in the credits.
Purpose. A short statement can be read at the end of the podcast such as, “This podcast was produced for [course name] at [institution’s name] in [semester, year]”.
