I teach AP Computer Science Principles so crowdsourcing is a familiar term. However, my students often confuse crowdsourcing with brainstorming. I usually share this article with them: https://innovationobserver.com/2017/03/06/dont-confuse-crowdsourcing-with-brainstorming/. Brainstorming is about throwing out an idea and asking people to comment. Crowdsourcing is about throwing out a problem and asking people to come up with creative solutions.
