We took all 862 videos from four edX courses offered in Fall 2012 and hand-classified each one based on its type (e.g., traditional lecture, problem-solving tutorial) and production style (e.g., PowerPoint slides, Khan-style tablet drawing, talking head). We automatically extracted other features such as length and speaking rate (words per minute). We then mined the edX server logs to obtain over 6.9 million video watching sessions from almost 128,000 students. To our knowledge, this is the largest-scale study of video engagement to date. Here's what we found and a couple recommendations:

This Free Principles of Economics text written collaboratively by a team of economics professors covers the scope and sequence for a two-semester principles of economics course. The text also includes many current examples, including; discussions on the great recession, the controversy among economists over the Affordable Care Act (Obamacare), the recent government shutdown, and the appointment of the United States' first female Federal Reserve chair, Janet Yellen. The pedagogical choices, chapter arrangements, and learning objective fulfillment were developed and vetted with feedback from educators dedicated to the project. The outcome is a balanced approach to micro and macro economics, to both Keynesian and classical views, and to the theory and application of economics concepts. Current events are treated in a politically-balanced way, as well.
