## Online Econometrics: Summer Wrap-up

After 13 live sessions, 13 quizzes, 4 problem sets, many hours of video lectures, hundreds of textbook pages, two exams, one big empirical project, and now 14 blog posts, I can say with confidence that everyone involved with my online econometrics class learned a lot this term. Here are the highlights:

## Review Session and Final Exam: Online Econometrics, Days 14 and 15

Last Wednesday was our last class meeting before the final exam, and I reserved most of our time to answer questions about any topics that have come up in the class. I asked them to send their questions the night before, and said that I would assume anyone that didn’t send questions had full command of the material and would help me answer everyone else’s questions during class. This incentive induced almost everyone to send questions before class.

## Working in Small Groups: Online Econometrics, Day 13

I am a huge believer in peer-to-peer learning and I love interspersing my in-person classes with small group exercises. It’s a nice break from lecturing and allows the students to actively work with the concepts I’m teaching that day. I walk around the room during these exercises and try to unstick any groups that get stuck.

## Quizzes with Canvas: Online Econometrics, Day 12.5

During the last month, my TA and I have created quizzes for all 13 modules in the class. Each quiz is made up of 10-15 multiple choice questions that test whether the student is absorbing the main points of the video lectures. The students get practice applying and combining the concepts with more difficult exercises in their homework. I think the quizzes have been successful, although with just 8 students in the class it’s hard to tell for sure.

## Reading Current Research: Online Econometrics, Day 12

We reached a big milestone Friday as my students read their first primary research articles and we discussed them during our live session. Coming into the course, most of my students knew that correlation doesn’t imply causation. For example, just because cities with more police tend to have higher crime rates doesn’t imply that hiring more police induces people to commit more crime. In a sense, econometrics is just a set of statistical methods for going beyond correlation and estimating actual causal effects.

## Remote Lecturing: Online Econometrics, Day 10

First Mile Communications was an Atlanta-based telecommunications firm that sold DSL Internet connections to local residents. Potential customers would call, and based on their address, First Mile would compute the straight-line distance to the nearest Central Office (CO). Using that distance, First Mile would approximate the length of the copper wire that connected the location to the CO. The standard rule they used was to multiply the straight-line distance by the square root of 2. This wire distance would determine how fast an Internet connection the firm could promise the customer.

## Midterm Feedback: Online Econometrics, Day 9

At the end of every semester, I take the last 15-20 minutes of the last class to get feedback about what went well and what could be improved the next time I teach the class. I find it more useful and constructive to do this as a discussion than to wait for anonymous evaluations (which are valuable in other ways). Because I’m trying so many new things in my online class, I did a midterm feedback session last Friday. Here’s what I learned:
