I have now been teaching at Duke University for 20 years. I have been through all kinds of teaching fads—active learning, team-based learning, alternative grading, service learning, etc. You might assume that I have become a better teacher over these many years. Yet I am noticing a curious trend in my course evaluations: Some of my students like me and my courses less and less.

As a teaching faculty member, this matters greatly to my own career trajectory, and so I’ve wondered and worried about what to do. Why am I struggling to teach well and why are my students struggling to learn?

Looking back on the past two decades of my teaching and reaching further back into my own college experience, I see six clear differences between now and then.

Difference No. 1: Access to Information

When I took my first college environmental science class, way back in 1992, I was mesmerized. This was before the days of Advanced Placement Environmental Science, so I came into the class knowing almost nothing about the topic, motivated by my naïve idea to be part of “saving the world.” To learn, I had a textbook (that I still have, all highlighted and marked up) and the lectures (for which I still have my notes). Sure, I could go to the library and find books and articles to learn more, but mostly I stuck to my textbook and my notes. I showed up to the lecture-based class to learn, to listen, to ask questions.

Today, my students show up in my course often having taken AP Environmental Science, with access to unlimited information about the course topics, and with AI assistants that will help them organize their notes, write their essays and prepare for exams. I have had to shift from expert to curator, spending hours sifting through online articles, podcasts (SO many podcasts) and videos, instead of relying on a single textbook. I look for content that will engage students, knowing that some may also spend their class period fact-checking my lectures, which brings me to …

Difference No. 2: Attention

When I lecture, I look out to a sea of stickered laptops, with students shifting their attention between me, my slides and their screens. I remind them that I can tell when they are watching TikTok or texting, because the class material probably isn’t causing their amused facial expressions.

Honestly, I am finding myself more distracted, too. While lecturing I am not only thinking about the lecture material and what’s on the next slide—I am also wondering how I can get my students’ attention. I often default to telling a personal anecdote, but even as they briefly look up to laugh, they just as quickly return their eyes to their screens.

The obvious advice would be to have more engaging activities than lecturing but …

Difference No. 3: More Lectures, Please

After 2020, one comment showed up over and over on my course evaluations: lecture more. My students seemed not to see the value of small-group activities, gallery walks, interactive data exercises and discussions. They felt that they were not learning as much, and some of them assumed that meant that I didn’t know as much, which leads me to …

Difference No. 4: Sense of Entitlement

While I teach at a private elite university, my colleagues across a range of institutions have backed this up: Some students seem to not have much respect for faculty. The most common way this shows up is at the end of the semester, when students send me emails about why my course policies resulted in a grade they think is unfair, or after an exam, when they argue that I did not grade them fairly, which leads me to …

Difference No. 5: Assessment Confusion

When I was in college, I took midterms and finals. I rewrote my notes, made flash cards, created potential exam questions, asked friends for old exams and studied a lot. I took multiple-choice exams and essay exams, in-class exams and take-home exams. When I first started teaching my lecture-based class, I assigned two midterms and a final. I took the business of writing exams seriously, often using short-answer and essay exams that took a whole lot of time to grade. I wanted the experience of taking the exam to help students feel like they had learned something, and the experience of studying to actually entice them to learn.

Then, two things happened. We faculty got all excited about alternative assessments, trying to make our classes more inclusive for more learning styles. And the students started rebelling about their exam grades, nitpicking our grading for a point here and there, angry that, as one student put it, I was “ruthless” in my grading. Students didn’t show up at my office hours eager to understand the concepts—they wanted more points.

So, I threw out exams in favor of shorter papers, discussions and activities. In fall 2024, I had 74 students and I gave a whopping 67 of them A’s. To do well in my class now, you don’t really have to learn anything. You just need to show up. Except the problem with grading for attendance is …

Difference No. 6: Our Students Are Struggling

We all know that our students are struggling with more mental and emotional health issues, perhaps due to COVID-related learning loss, the state of the world and so many other things. Many of us include mental health resources in our syllabus, but we know that’s not enough. Students are much more open about their struggles with us, but we aren’t trained therapists and often don’t know the right thing to say. Who am I to determine whether or not one student’s excuse for missing a class is valid while another’s is not? How can I keep extending the deadlines for a struggling student while keeping the deadline firm for the rest? Sure, there are suggestions for this (e.g., offer everyone a “late assignment” ticket to use), but I still spend a lot of time sifting through student email requests for extensions and understanding. How can we be fair to all of our students while maintaining the rhythm of course expectations?

Usually, one acknowledges the differences between students now and “back then” at retirement, reflecting on the long arc of a teaching career. But I am not at the end—I have a long way to go (hopefully). I am expected to be good at this in order to get reappointed to my teaching faculty position.

Teaching requires much more agility now as we attempt to adapt to the ever-expanding information sphere, our students’ needs, and the state of the community and world beyond our classrooms. Instead of jumping to solutions (more active learning!), I think it’s reasonable to step back and acknowledge that there is no one change we need to make to be more effective educators in 2025. We also can acknowledge that some of the strategies we are using to make our classes more engaging and inclusive might backfire, and that there still is a time and place for really good, engaging lectures and really hard, useful exams.

There are fads in teaching, and over the past 20 years, I have seen and tried plenty of them. We prize teaching innovation, highlighting new techniques as smashing successes. But sometimes we learn that our best-laid plans don’t work out, that what students really want is to hear from an expert, someone who can help them sort through the overwhelming crush of information to find a narrative that is relevant and meaningful.

The students in our classrooms are not the same students we were, but maybe there is still a way to spark their enthusiasm for our subjects by simply asking them to be present. As debates about the value of higher education swirl around us, maybe caring about our students and their learning means asking them to put away their screens, take out a notebook and be present for our lectures, discussions and occasional gallery walk. For my part, I’m reminding myself that some students aren’t all that different than I was—curious, excited, eager to learn—and that I owe it to them to keep showing up committed to their learning and, maybe, prepared with a few more light-on-text lecture slides.
