To celebrate acceptance of my abstract at BCCE 2024 in Lexington, I thought I’d get some of my experiences from undergrad chemistry at Kentucky down on paper. In a sense, I never really left college (just moved to “the other side of the desk”), so many of those experiences have stuck with me over the years. Read on for a taste of chemical education in the 2000s!
My first chemistry course at Kentucky was General Chemistry II in Fall 2004 with Harriet Ades, an aged Jewish woman who, in retrospect, had clearly been worn down by years of teaching obnoxiously large courses. I didn’t take AP Chemistry, but Kentucky ran a placement test that gave credit for General Chemistry I, and I managed to pass it. Thanks to the dual advantages of chemistry running in the family and my being motivated to impress a girl, I applied myself pretty hard in high school chemistry and it paid off.
Ades’s course was my first exposure to a large college STEM classroom. My memory’s a little fuzzy, but I believe she used transparencies and an overhead projector—there were no smart boards or touch screens yet in 2004. Her lectures were mostly bland, although on very rare occasions she would get excited. We lived for those moments!
The thing I remember most from that course is the textbook. I had a floppy paperback version of the eighth edition of Chang with an electrostatic potential map on the cover. The book came with a CD full of videos of worked example problems by a company called Thinkwell, in the “document camera + talking head” style of Tyler DeWitt. Those videos were great! At the time, I think I figured the presenters were actors, or maybe high school chemistry teachers. Years later, doing work for Organic Reactions, I came across an eerily familiar author photo and realized that one of those presenters was organometallic chemistry professor Dean Harman! (Now I know better—publishers use faculty in these things because they know we’d make those videos for free.) Never did figure out who the Asian guy was, though.
I bring up the textbook and videos because they spurred me to adopt the dubious policy of attending every other class and using the book to fill in the gaps. Every day after I attended that class, I would drink a Dr. Pepper out of the vending machine in the Chemistry-Physics Building. (My diet in college could be a post unto itself—long live K Lair.) By the middle of the term, I had developed a distinctive shake in my hands before I “got my Dr. Pepper” for the day. Probably spent a good bit of time in that class thinking about the upcoming caffeine hit anyway. On my “days off,” I realized I could spend a half hour reading and taking notes on the textbook instead of an hour sitting in class. Thirty minutes of freedom!
I also remember making the conscious decision not to learn how to calculate the pH of a buffer after addition of strong acid or base to it. That was another highly questionable example of college “strategery.” That course used multiple-choice exams and I was comfortable applying the Henderson-Hasselbalch equation to determine the pH of a buffer. I also understood The Big IdeaTM of buffers that strong acid and base don’t change their pH much. Logically then, in a question asking for the pH of a buffer solution after the addition of strong acid or base, the correct answer is most likely the answer choice closest to (but not equal to!) the original pH of the buffer. In the event of an overwhelmed buffer or several close values, I told myself I was just going to guess and take the hit! I don’t regret the decision—it maximized my happiness at the time—but I do use it as a cautionary tale for students and to encourage them to at least engage in metacognition.
My first and only General Chemistry Laboratory course was in Spring 2005, bright and early at 8:00 am. Thankfully, I was blessed with an extremely peppy lab partner who never failed to shake me out of sleep. True to form, she tracked me down years later to try to rope me into a multi-level marketing scheme. (Yes, I went to the meeting. Yes, because she was a girl. Yes, I regret it.) Our TA was a well-meaning but inept international graduate student; my lab partner derived endless joy from messing with him, not so much in a spiteful or mean way, but in the spirit of initiating him into her version of “American college culture.” That’s about all I remember from that lab, as whatever lab reports I put together are lost to the sands of time.
I feel like students often don’t appreciate how important those first couple of semesters are in establishing the life habits and study habits they’ll carry through college and even their future careers. I carved out time every day to run in the late afternoon—back then, the Johnson Center was brand new—and I still try to run at least once a week. My diet was crap and remained crap until having kids (eight years later!) basically forced me to become a passable cook. The silver lining of the “attend every other class” policy was that I figured out that, at least in chemistry, my learning (1) was up to me, not the professor and (2) could usually happen more efficiently outside of class by reading and taking notes than in class. Lectures and YouTube videos are less efficient than reading, gang!
Next up, I’ll dig into my sophomore year and my organic chemistry experience. Stay tuned!
