Select Student Quotations from Open-Ended Course Evaluation Questions
"My instructor, Professor Osei, made learning very accessible during the 2026 Summer I semester, especially given the class met remotely via Zoom. Professor Osei encouraged all students to participate daily in class, and encouraged students; if their answers were incorrect or wrong, he was still polite in his correcting, which in my view is very important in the learning process. You are here to learn, and you should not be expected to know an answer immediately, which is something Professor Osei understands." (Summer session I 2026, PLCY 310 - Microeconomic Foundations for Public Policy)

"Christian was one of the best TA's I've had this semester. His extensive knowledge on the subject, as well as his overall patience with our small classroom, has been a huge help for this class. I also really appreciated his ability to break down the subject to explain the intricacies of certain topics." (Spring 2026, PLCY 460 - Quantitative Methods for Public Policy (Stata class))

"Christian did a great job of teaching a difficult and intensive course. In a class like this, I appreciate having multiple ways to show knowledge. Having problem sets alongside exams helped me to practice and work through topics in different ways. I had no background in economics prior to this class, and while I did struggle at times with the economic language in our problems, Christian always made sure he explained the context further and helped me to process the economics alongside the math. I appreciated how he had students work through problems on the board in class, as this helped us to discuss approaches to solving problems, recognize where errors can occur, and improve on our ability to engage with the content."

"Recitations were super relaxed and enjoyable and felt more like a casual get together to do stata than mandatory class. I loved it!" (Spring 2024, PLCY 460 - Quantitative Methods for Public Policy (Stata class))

"Christian held regular office hours and was accessible for students. If I did not understand something, he would break the concept down into its simpler components and re–explain it in a broader context. Christian was also kind and considerate when I found myself with technical difficulties. Thank you Christian"  (Fall 2023, PLCY 460 - Quantitative Methods for Public Policy (Stata class))
