This is an excellent introduction to the basics of epidemiology. I took it at the testing time of COVID-19 to be able to critique the evidence presented in the vast body of news coverage. The course structure is well balanced and key epidemiology basics covered. The explanations to concepts are very clear, often with reference to real-life examples for easier understanding. The course slides are detailed but concise, with key information highlighted. The additional reading provides useful extracurricular materials in greater depth. After learning this course, I find myself more confident in reading publications on public health studies for my work in air quality, which is such a wonderful reward for following through this course. Many thanks to Drs Alexander and Yeatts! One of my suggestions for improvement would be to provide detailed explanations to the questions in the weekly quizzes. Currently reviewing the answered questions does not provide any informative feedback apart from right or wrong - it does not even show my answers, which is not very helpful for effective learning from the mistakes. Another suggestion may be to add sample size calculations for each study design? However, these are really minor comments, compared with the great materials the two instructors prepared. Once again, thanks very much!

Overall this was a good course! There were good topics in each module, and modules were organized in a logical sequence.

Some of the modules (especially those dealing with statistical analysis) were a bit confusing and I had to research a bit more to fully understand them. Also, some of the quiz questions were complicated to understand due to the answer types, phrasing, and they contained information not covered in that specific module.

But, overall it was an enjoyable course that allowed for a basic understanding of epidemiology and its role on public health. The videos' lengths were adequate, most concepts were explained thoroughly and effectively, and the facilitators did a good job of providing enough examples to further explain the application of each concept.

Excellent introduction to a broad subject. Clear, concise and well structured. Three suggestions of improvements:

1) Please share the slides separately as a course companion.

2) The quizzes requires some improvement and why don’t provide explanations for some of the answers - specially those with multiple choices to get the full point on the question

3) Some More concrete examples and more exercises (homework) would be extremely useful in the chapter of understanding measures of disease frequency and Measures of association. Granted it requires more Maths (statistics and probability) understanding but that’s the whole point of those chapters.

Thanks again, truly enjoyed.

The course gives an overall good introduction to epidemiology applied to public health. The classes are well structured and the basic concepts are cleary explained, providing a more pratical insight on the uses and importance of clinical and epidemiological studies to public health. In my opinion, the course fill its purpose which is to give an basic introduction to epidemiology.

However, considering its six weeks long duration, I think that it may be suitable to add facultative activities (videos or even supplemental material) to provide those who want to go deeper a more complete learning experience.

I very much appreciated the examples as they are critical to grasping the concept itself and not to mention the nuances between various terminologies. Although I realize that some preliminary understanding of statistics will help you get there sooner. I would have loved more examples and possible case studies, especially where discernment of which methodologies are appropriate with respect to the problem statement and which are not (e.g. study designs) would have made the concepts a bit more sticky. All in all, I enjoyed the curriculum. Thank you, Professors and UNC :)

I took this course as a refresher since I have been involved in numerous clinical and medical research in the past. I appreciated the mentioned of the Malaria and TB studies as well, as I have been involved with them in the laboratory side in Africa. The only issue I had with the course, was that it wasn't until at the end that I just found out that I could have been posting my questions. Overall for a virtual class, it was excellent! My Sincere thanks to Dr. Yeatts and Dr. Alexdander for a well given lecture. Look forward to my certificate :-)

An interesting introduction to epidemiology. I felt that the statistical concepts this course covered were clearly explained, and the numerical examples helped further my understanding of these principles.

However, from the course description, I expected the course to talk more about concepts (it covered this a little bit, e.g. the Bradford Hill criteria) and perhaps the state of modern-day epidemiology than it did (for example, studies and successes from within the last 10 years?). I would love to see a follow-up module on that topic!

Firstly, the course structure was well developed. I liked the encorporation of the history of Public Health, the measures of disease occurrenece and disease association. Furthermore, it was good to apply these measures of disease occurence and association in the research designs. The leacturers are also well acquinted in transfering knowledge. You both explained well and made it easiere for the learner to follow through the online learning process. Thank you so much. It was indeed a happy learning. Thanks once again.

Great introduction to epidemiology. I found the entire course very interesting and well taught. I wanted to take this course because I'm very interested in matters of public health and population health. I did not realize just how quantitative this discipline is - I feel like I should have anticipated and understood that going into this introduction, but I didn't and found it challenging to get my head around exactly how the various measurements inform epidemiologists. Great course and two very capable instructors!

I LIKED THE COURSE VERY MUCH, IT ALLOWED ME TO REMEMBER THINGS I KNEW FROM COLLEGE AND THAT I MIGHT NEED THEM IN MY NEED JOB IN THE RESEARCH FIELD. THE ONLY THING I DIDN´T LIKE WAS THE QUESTIONS THAT HAD MULTIPLE ANSWERS AND IF YOU DIDN´T CHOOSE ONE YOU GOT IT WRONG THE WERE NO HALF POINTS AND THATS WHY IT TOOK MY LIKE 3 TRIES IN ONE QUIZ, BUT THE LECTURES AND VIDEOS WERE VERY GOOD. I KNEW MOST THINGS BUT I BELIEVE THAT PEOPLE THAT NEVER HAVE RECEIVE CLASSES ABOUT THIS TOPICS MIGHT HAVE UNDERSTAND IT FAST AS WELL.

Good course, very well structured, well signposted, progressive, very clear, with a good use of the media. As for the content, the examples are not always well connected to the theory. The speakers speak at a good pace, not too slow not too fast but their tone is monotonous and it is a little bit formal. Therefore the course is a little dull. As the course is very introductory, it would have been nice to be directed to other more advanced courses either online or residential.

The course provides a good introduction to epidemiology. Both teachers are relaxed and speak very well, which is important for foreign students. I would add more intermediate ,practice exercises before quizzes, intermingling them with lectures. Absorbing too much material before the quiz is not always easy. Especially formulas should be practiced repeatedly with some real life problems, although not too difficult ones, in line with the purpose of the course.
