Teaching
Pedagogy
I love teaching. It is an enormous responsibility and an enormous privilege. When done with care, the rewards are enormous too. I find that college-aged students have an insatiable appetite for questioning the world around them. When I invest time and effort into my pedagogical practice, my students respond with an invigorating degree of curiosity and engagement. In order to facilitate the most positive, accessible, and rewarding classroom environment that I can, I use a number of strategies.
I prioritize inclusivity. I am unequivocal in my efforts to create a classroom that is actively antiracist and affirming of all sexual orientations, gender identities, and educational backgrounds. This is reflected in my inclusive language in the classroom, as well as my continuing efforts to diversify my syllabi.
I cold-call. I believe very strongly in the practice often referred to as cold-calling (although I prefer the gentler voluntelling). I implement this practice for several reasons. First, knowing that students will be asked to answer questions in each class incentivizes preparation. Second, thinking through things together and out loud helps us learn. Third, when the instructor selects students to answer questions, this helps ensure that each student is afforded an equal opportunity to participate. Otherwise, it is not uncommon for a handful of confident students to dominate the discussion. Cold-calling helps mitigate this imbalance. (See, for example, this recent study which suggests that cold-calling mitigates gender disparities in class participation and encourages students to volunteer more frequently.)
I balance skills-based and knowledge-based learning. The latter centers on learning the content of the course, while the former centers on cultivating a set of skills that the students can transfer to other settings. These are skills such as effective writing, reading comprehension, and asking well-formed questions. I have developed a number of strategies that I believe successfully prioritize both kinds of learning. For example, I assign student-led debates. I find that nothing incentivizes students to learn a philosophical position like having to reconstruct it (and then defend it) in front of their peers. I also assign scaffolded research projects by implementing small checkpoints over the course of a semester. I break down each step of the research process, from choosing a research question and finding potentially relevant sources to annotating, drafting, and giving feedback.
I incentivize broad engagement with the field. It doesn’t matter whether my students are headed for dental school, consulting, professional ballet, or a graduate program. No matter their career aspirations, I encourage them to engage with the field of philosophy after the semester has ended by submitting their research papers to undergraduate journals and conferences. Beyond another CV line, this presents students with an opportunity to apply the skills they learned in my course outside of the classroom. Submitting to a journal or presenting at a conference gives us a chance to practice public speaking, revising, and simply hitting “submit.” Each of these is a valuable skill regardless of one’s career trajectory. Therefore, I encourage broader engagement with the field by building these opportunities into my course syllabi.

Philosophy of Biology
In this course, we explore philosophical issues surrounding several key concepts in evolutionary biology. Through class discussions, reading responses, team debates, and a research paper, we investigate philosophical aspects of the following: natural selection, development, inheritance, the scope and adequacy of evolutionary theory, biological function, what it means to be an organism, what it means to be a species, race, and feminist perspectives on evolutionary biology.
Writing 101:
Closing the Gender Gap in STEM
In this writing course, we read works by and about female scientists across disciplines—both the unsung heroes in the history of science as well as female pioneers of the STEM workforce today. We also read and discuss feminist perspectives on science, such as the gendered bias of biological models and evolutionary concepts. Finally, we read and discuss recent scientific literature on systemic inequities in STEM, as well as possible social and economic causes for these inequities.
Logic
This is a standard undergraduate logic syllabus. It covers formal and informal fallacies, syntax and semantics of propositional and predicate logic, transcription, natural deduction, and truth trees.
What My Students Are Saying
The following testimonials are from anonymous course evaluations.
Caleb was, hands down, the best instructor I’ve ever had in facilitating an inclusive and fun learning environment. After a single run-through of every person in the class’s name, he had them down. Just like that — I’ve never had an instructor who cared about making their students feel welcome to the extent that Caleb did. He made sure that nobody ever felt that their question was dumb or poorly formulated, and because of that the participation in the class was unmatched.

Caleb was there for his students, always checking in on us both with how we are doing in his class and in other aspects. The class environment he created was truly something unmatched. It was an experience I will think upon happily when remembering my freshman year due to the dynamic and friendships he cultivated with his teaching style, the skills I learned from his instruction, and the amount of care Caleb took in his teaching.

I greatly advanced my abilities to write thoughtfully and concisely. Professor Hazelwood provided excellent feedback that went beyond singular writing assignments to improve my overall writing style. I also developed skills in analyzing historical texts and comparing philosophical perspectives. In our discussions, we often challenged and supported various positions on feminism, STEM, and workforce representation, which helped me to gain insight into my own views and learn how to best articulate them.

Caleb was a phenomenal instructor in this course. He was extremely knowledgeable, personable, and clear in his instruction of the material. He made the course engaging and fun to take while teaching us difficult concepts in a very unambiguous way. Caleb always made sure that everyone in the class grasped the concepts before moving on; no student was left behind in his course. He was readily available to meet outside of the scheduled class time and encouraged all of his students to reach beyond the course material and apply our learning to our respective fields.

The overall learning environment was incredible, I felt extremely well supported by Caleb Hazelwood. We were encouraged to engage in class discussions, and our contributions were valued. The debate format was extremely fun and engaging as both debate participants and as viewers. The high amount of out of class opportunities to listen to relevant talks was awesome as well, and I appreciated our instructor letting us know about these opportunities.

Mr. Hazelwood was exceptional in making you learn a vast amount of knowledge without putting that stress of learning on you. His class is very well structured in which it makes you feel like working more.
