Many STEM majors here have the same rite of passage: core lab. For non-lab majors, core lab is a class that is purely to teach you about lab techniques and critical thinking skills that are useful for writing our theses. They usually involve a bit of a simulated lab experience where you discover new findings while the teachers guide you through the motions of a lab research experience. 

Molecular biology’s core lab meets twice a week for 3 hours and then a small 50 minute lecture/precept on Fridays for half the semester. Other majors have similar constraints. However, while at first it may seem a bit overwhelming and even redundant if you’ve already done these procedures in a lab or are in a lab that definitely will not be using any procedures you learn, core lab goes beyond just teaching you technical skills. 

I too was confused as to why I was here and why this mattered, but over time, I began to internalize one of the real skills this class is meant to teach you, something that pipetting will never give you: asking the right questions.

For most STEM majors at Princeton, one of the requirements is a course known informally as Core Lab. This class aims to equip students with laboratory skills required to succeed as a scientist in the field. It is usually composed of two 3-hour labs and one lecture per week. As a neuroscience major, I am currently taking NEU 350: Laboratory in Principles of Neuroscience, a class designed to introduce students to modern methods of analyzing neural activity—from the level of single neurons to large-scale networks underlying cognition. The course covers a range of techniques, including intracellular and extracellular recordings, optogenetics, EEG, and fMRI. After weeks of conducting designed experiments, it culminates in an independent research project where students design and conduct their own experiments based on knowledge and skills learned throughout the semester.

The structure of a “standard” Princeton course usually includes a mix of lectures, precepts, or seminars which likely have a midterm and final. While some of these courses may have “lab” components where you spend a couple hours once a week doing a hands-on assignment, there exist many courses at Princeton which are instead entirely focused on conducting hands-on, lab-based research with a small team that works closely with professors who provide mentorship as you work on an original research project. If you’ve ever wanted to take a class that is far different from anything else at Princeton by teaching you hands-on skills and giving the opportunity for a new project, these types of courses might be for you!

Some of these courses are year-long sequences like AST250 Space Physics Lab I and AST251 Space Physics Lab II, which I took during the 2022-2023 academic year. This was one of my favorite course experiences at Princeton and was certainly the most engaging. The skills we learned were invaluable, and as we worked closely with the professors and each other, our year-long project became an unforgettable experience.

Reading Courses: A Guide

Posted on by

As course selection begins, you might find yourself searching endlessly through the Course Offerings webpage, trying to craft the perfect schedule for next semester. You’re probably weighing a number of different factors— the professor, the class topic, the reading list, the different requirements it fulfills— and trying to balance these in the best way possible.There is another possibility here, which you can’t find in the course offerings: reading courses. Not advertised on department websites or listed with course offerings, reading courses are some of Princeton’s hidden academic gems. The University defines a reading course as a specially designed course not normally offered as part of the curriculum that is arranged between a student and a faculty member. These courses count for academic credit, and focus on a topic of the student’s choosing. If you’ve ever dreamed about designing your own course, this is your opportunity.

It’s always a mixed bag of emotions when it comes to course selection. Personally, I find the period between when the next semester’s courses are released and before the course selection date to be especially fun—I can play around with the different ideal schedules (potentially having no-class Fridays and no night classes), look ahead to the rest of the courses that I’ll be taking during my time here, and discover new classes. Whether people end up choosing to take classes to fulfill requirements, classes that interest them, or classes that could teach them important skills, an important aspect in choosing courses for the upcoming semester is course planning. TigerApps is a group of student developers that builds apps to improve the campus life experience for Princeton students. One of the TigerApps created is ReCal, which is the most popular way to aid in course planning and ensure a smooth process for course selection. Recently, TigerJunction ReCal+, an application for course planning inspired by ReCal and designed to be an “improved” version, has made its rounds among students. As course selection season is upon us, I wanted to take the opportunity to show how I plan my courses for the next semester and provide an in-depth comparison between ReCal and TigerJunction ReCal+ to inform how other students plan their courses for the upcoming semesters.

My BSE Spring Semester Experience in the Engineering Sequence

Posted on by Shannon Yeow

After having written “My BSE Fall Semester Experience in the Engineering Sequence”, I wanted to continue writing about my experience in the spring semester portion of the sequence; if you haven’t read my first post yet, go read it! To reiterate, the Engineering Sequence is a set of five courses intended to fulfill first-year engineering requirements through an introduction to engineering fundamentals in the context of real-world applications. BSE degree requirements include four semesters of math, two semesters of physics, one semester of chemistry, and every first-year student is required to take one semester of writing seminar. The Engineering Sequence begins at the Integral Calculus (Calculus II) and the Physics Mechanics level, meaning that it will cover for the two required semesters of physics and the four semesters of math in five courses throughout three semesters. Read on to learn more about the spring sequence!

My BSE Fall Semester Experience in the Engineering Sequence

Posted on by Shannon Yeow

College is daunting. It’s normal for incoming first-years to feel uncertain about many things, especially course selection. I remember looking through every course on the course offerings page to determine the classes I would be taking in the fall, and feeling overwhelmed by the sheer number of options available. I came into Princeton as a prospective COS (Computer Science) BSE student, so my class choices were inevitably influenced by my BSE degree requirements. BSE degree requirements include four semesters of math, two semesters of physics, one semester of chemistry, and every first-year is required to take one semester of writing seminar. Read on to learn about my experiences in the EGR sequence, starting with EGR 151.

Thank you to the best friends in the world for sending in their favorite courses!

“Does anyone know a good English class?” “I need to fulfill my history requirement.” “I am looking for a chill, creative P/D/F course.” Everyone is searching for the best schedule possible and I know that many of you are open for suggestions. In my last post, I wrote about my favorite courses at Princeton as a SPIA major interested in law and service (see post here). But, I understand that every Princeton student is unique, so I have spoken with classmates and friends within other majors to better understand the full Princeton experience. Thus, without further ado, here are the most unforgettable courses that they have taken at Princeton.

Rainy fall leaves will turn to snowy flakes before you know it; it’s never too early to plan some future courses!

“I have to wake up at 6:23 AM for course enrollment?!” Yes. You do. But you got this! It’s true that course enrollment is still a month away, but it is never too early to start drafting your schedule to avoid this “oh no” early-bird moment. Generally, I recommend taking courses that excite you, even if they are outside of your major, because before you know it you’ll be an old senior like me wishing you had time to take more. Everyone has a different taste in classes. I am a SPIA major who is passionate about service, social justice, and law, but I have tried to take unique and expansive research-based classes. Thus, without further ado, here are 5 of my most memorable classes at Princeton, in no particular order, and why they might be of interest to you:

Why Zoom Office Hours Are Better (and tips for making the best use of them)

Posted on by Yodahe Gebreegziabher

If there is one thing we as students have mastered in the COVID-19 pandemic, it is Zoom and the Zoom environment. Looking back to last spring, it is admirable how educational institutions and students adapted to an unprecedented global crisis and continued with their academic and non-academic roles. Here at Princeton, the transition to Zoom was relatively smooth given the uncertainty and fear at the time. Although the initial stages of scheduling an online semester were difficult, there was a strong desire to sustain many of Princeton’s activities for the virtual campus community. The concerted efforts of students, faculty and staff have paid off. The three semesters of virtual learning I’ve had so far mimicked almost all the characteristics of the usual in-person experience I’ve come to expect at Princeton, including access to office hours.

The main medium for virtual interaction is Zoom, and it has been adapted for almost every facet of university activity, from school clubs and organizations to school hosted events and webinars. In this post, I will take a closer look at the Zoom office hours, their many advantages and in some cases, how they are actually better than in-person ones. I will then offer some suggestions for making the best use of Zoom office hours this spring.
