Review Summary Updated April 07, 2026

This course ditches traditional exams and rigid schedules for a chill, independent research experience where you will quickly pivot from learning basic lab protocols to designing your own group experiments. Grading is straightforward and rests entirely on your lab notebook, a short proposal, and a final paper rather than stressful tests, though you should be prepared to check on your specimens at odd hours. The instructor is widely praised for being highly approachable and focused on actual learning over grade-chasing, but you will need to navigate a laid-back, sometimes unstructured format that rewards self-motivation. While a handful of past reviews mention subjective grading or recommend coming in with prior research experience, the consensus is clear: this is an easygoing, flexible class perfect for building real lab confidence without heavy pressure.

Yes, this class is fairly disorganized but it's an easy A class so whatever. To be quite honest, I don't understand how anyone could not get an A. For the most part, you're working on your independent research that either Keller and/or Caroline suggest or come up with your own idea to test on the Xenopus laevis embryos. WARNING: because this IS a developmental class, the experiments you choose to perform are very time-dependent. You may be in the lab at odd hours (7AM or 11PM for example). Grade breakdown: 10%=participation, 40%=lab journal, and 50%=lab report on your independent research project (written in the style of an actual research paper). Good luck!

It's a fairly disorganized class, but there's a lot of room for individual research and study. You're in and out of the lab at odd hours outside of class as well as in class research. The professor is really flexible.

This class was amazing. Instead of being your typical canned lab, you get to decide what you research and as long as you get approved the rest is up to you. The independence is thrilling, and a good experience and Keller is ever the enthusiest about new finds. The only grades come from the lab notebook you keep and your final lab report but keller helps you on both of those so unless you ignore his advice you cannot go wrong.

This class is pretty awesome- you get to design and conduct your own experiments. The first part of the class is learning general info about Xenopus frogs, and the second half is conducting a group experiment. You do the the experiment on your own time (you have a flexible schedule, but sometimes you have to come in late at night or on the weekends to work on your embryos). Keller and Caroline (TA) are really smart and helpful. This class was a great way to learn about dev. bio and get experience with current lab equipment and techniques. Grade was participation, lab notebook, and final lab report (50%).

Ray Keller is fabulous. I don't think that he is that organized, but regardless he is very knowledgeable in his field. I didn't spend much time in the lab and our grade consisted of 2 4-5 page lab reports (including pictures) and 2 notebook checks. I don't think that anyone got below a B in the course. I personally got an A-.
