Five years ago, I was in the second semester of the first year of my undergraduate degree. I was majoring in economics, so I was taking all of the very general first-year Intro To Economics courses. As a lot of other courses also had some first-year economics requirements, these classes were usually held in the largest lecture hall, which could fit about 500 students. My class at the time had about 300, but on average only about 150 to 200 usually showed up to the weekly lectures.
One day, my friends and I walked into the lecture hall as we normally did and paused for a moment. The lecture hall was looking unusually full. Thinking it was a bit odd, we went to find some seats near the back and took a look around. We recognized about a quarter of the faces — too big of a class to actually recognize everyone — but given we were first-years, we realized that a good bit of the group looked quite older than us.
Finally, our professor entered the classroom. He apologized for being a couple of minutes late and went to set up his slides.
Suddenly, someone else entered the classroom and walked up to the stage. He went up to our professor and they began furiously discussing things. The entire lecture hall started up talking, wondering aloud what was going on. It continued until the two men stepped to the podium.
Professor: “How many people are here for Intro To Econ Policy?”
About 200 people raised their hands. Immediately, everyone was very confused, as about a third hadn’t moved at all. Then, the other man stepped up.
Man: “How many people are here for [third-year computer science class]?”
Immediately, the other third of the hands went up, and the lecture hall erupted into laughter. When the professors were finally able to calm everyone down, they began explaining
Man: “As a third of you would know, our normal lecture hall was booked out this week for an external lecture, so we got assigned to this hall. Apparently, the scheduler missed that there is always a first-year economics class here.”
Professor: “As this is the last lecture before midterms, and the class is normally an hour long, neither one of us planned a full lecture. And since it would take way too long to try and contact the scheduler and find another room, we have a proposal.”
Man: “The first-years will get the opportunity to learn a bit of ‘Fuzzy Logic’ during the first half of the lecture…”
Professor: “And the third-years will get the opportunity to learn about European Economic Policy during the second half!”
And that’s how they did it! Both professors took the lecture very informally, taking questions from whoever had them, no matter how silly they may have seemed to the other group. It ended up being one of the most entertaining classes of my first year of college!
And don’t worry; both professors posted extra office hours to prep for the midterms in case we had more questions than the half of lecture permitted.
