You could say “Once you learn the jargon, you save precious time accessing and using it to communicate to (and having your ideas accepted by) others in the field, including your instructors.” Riley<br/>
says that most memorization (done correctly) saves time. He relates this to the efficiency of working memory, the place information is held in preparation for thinking. Working memory has limited capacity. If you try to get too much in it, other stuff has<br/>
to get kicked out. But once jargon has been mastered, it takes up less space in working memory, thus making room for more complex types of thinking.
