This course was a good primer for those who have little or no background in epidemiology and public health. In particular, the instructor set the practice of public health in the context of its longstanding history and the tools that were developed by researchers and government officials to collect population and health data, in order to respond to health issues and threats in a way that traditional, individualized clinical practice was. However, the instructor does not necessarily make the learning objectives clear in each week, and often tests on material that was only vaguely mentioned in the lecture videos or was poorly defined. The last week of the course, on mapping health data with GIS tools, is promising, as it introduces the student to powerful data tools and comprehensive health and geographic data available to the public. However, it falls short in that this segment provides only a cursory treatment of these tools, walking through an exercise that does not reflect the practical usage of such aids and therefore fails to provide the opportunity for students to attain rudimentary skills.

The subjects covered were less intensive and technical than I expected. Most of the information covered, I was already familiar with from my undergraduate studies. The biggest point of difficulty was the mapping exercise at the end, seeing as the students were mostly left to navigate totally unfamiliar territory on their own with the QGIS software. However, if it weren't for this course, I would not be at all familiar with mapping softwares or how to create content using one. For this, I am grateful to Johns Hopkins for the course.

Thank you for the efforts you have put in this course. I would suggest that the course will make a much more interactive and engaging presentations during the lectures to help those who learn faster with focus-sustaining visuals.
