In colleges and universities there are many different disciplinary language communities. When a professor from one discipline uses the same technical term as a professor from another discipline, it can be confusing to undergraduates who may not realize that the same word may mean different things in those two different academic language communities. This is why making a correct interpretation of what each professor means requires that the students learn

how their words are used by the members of their language communities

how to file complaints with the dean that the faculty members are being unfair

how to ask the professors to stop using technical terminology

how to avoid taking courses except in one discipline at a time
