Tracking asthma-related absences from school
Maybe the most ubiquitous, and slippery, statement about asthma is that it is the primary cause of absence from school. For example: “Asthma is considered the leading cause of school absence among children 5-17. It accounts for an estimated 14 million missed days of school each year.” Asthma absences are considered an important surveillance indicator [...]
Building CAPTCHAs for public health
Over the weekend, I came across a project that teaches a little bit of electrical engineering through CAPTCHAs – the challenge-response test used across the web to determine that a response is not generated by a computer. The open source project, call Resisty, is a WordPress plugin that requires a person visiting a blog determine [...]

This week, JACI and ERJ [...]

Digital Learning submission
The public comment period for the MacArthur Foundation’s Digital Media / Reimagining Learning competition has opened. The scope and cleverness of these projects is extraordinary and very motivating. If you have a minute, it’s well worth reviewing and contributing to the conversation- http://bit.ly/cjKa0S. I humbly added my classroom epi project (EpiLab) to the mix. It’s [...]
