Outstanding course. Outstanding content. Outstanding delivery. The videos are 10 minutes each with at most with the concept explained in the first couple of minutes and then good examples provided. The professor has a clear succinct manner in which he explains the ideas and then follows up with modern day examples. The quizzes are not a cake walk if you dont listen to the lectures clearly and pay attention but that should not be a problem since the lectures are a pleasure to watch. Fantastic course. I just hope this team develops a more advanced version of the concept of competitive strategy.

I had no prior experience with this course per se but had read about the various concepts in other times and for pure entertainment. This course took all the ideas I thought I knew and made me question my beliefs. It put me in an awkward position by asking me questions that I had never thought I would have to answer. I highly recommend this course for everyone regardless of your background. I dropped out because I just did not have the time to finish the course.

Since I just ended my last week quiz in this course, I think I am in a state where I can give a fair and balanced review on the course quality. The material taught is definitely useful. The examples provided by the lecturer have value and allow for one to get a practical outlook on a theoretical concept. The readings assigned were appropriate and did help in cementing an idea. The quizzes have only one deadline, at the end of the course which does alleviate the pressure on students who want to balance multiple things and still get a statement of completion. The videos (thankfully) are short and I listened to most of them on a higher speed which made them shorter. The quiz questions are straight out of the content so there are no shockers. The way this course has been set up is to encourage people to engage with it and not feel pressure. Compared to other courses, this course was extremely easy, though I for one appreciated the simplicity of the material. The only thing I disliked was the ability to take a quiz 100 times and for each try of the quiz to just have questions re-arranged. Maybe if the quizzes were slightly more challenging, the course could still have been super easy yet give the students some manner of challenge.

I took this course because I have an interest in the area of safety in health care. The fact that this was a Johns Hopkins course made it doubly attractive for me since JHU is doing a lot of great work in the areas of safety sciences. This course is probably best for someone who has NO idea of the concepts and philosophies behind the sciences of safety in hospitals. The ideas presented are derived from real life implementations so they have a practical ring to them. The course on the whole was easy but the quiz was not straight forward which I liked, simply because it made me refer to the notes once more and completely grasp the ideas. The peer assessments were also mildly challenging and I had fun finishing them. They were not a walk in the park which meant I needed to think hard about what I wanted to talk about. At 5 weeks, this course is one week too long. In a regular academic setting, this would probably be a day long seminar. Even though I did not learn much from the course, it is still a good course and the presenters are people who live 'safety' every day of their work.

This was a hard course for me. Even though I knew some bits and pieces about molecular biology, I still found this course hard to follow. Partially this was due to the lecture material and the manner in which it was delivered. I am NOT complaining about Dr. Iyer here. He is doing us a favor by spending his time on delivering a pretty difficult topic. What I am highlighting is that his teaching style will be hard for some course takers to follow. I also found the quizzes ambiguous and difficult. I think the difficulty arose from the fact that Dr. Iyer would teach a concept, all the while peppering some targeted comments about some cellular entity here and there, which in the normal course of conversations, I would forget because I was looking for the general models of system biology. The same specific comments/examples would make their way into the quiz and make me have to traverse through the lecture again to find an answer. This course needs some basic expertise in molecular biology to be useful. I will probably take it again but this time after I have spent more time brushing up (and beefing up) my basics.

I have no background in molecular biology and this lack of knowledge hurt me previously when I had spent about 3 weeks on Systems Biology and had to drop it eventually. The same deficiency came back to haunt me this time around too. The course itself is excellent. The teacher was very clear and the work she was presenting was well organized. The quizzes were fair and if you had spent the time understanding the lecture, you would have been ok but I knew I was struggling because it would take double the time it was expected of students. For every one point the teacher conveyed, I was spending 10-15 minutes getting a grasp of the basic underlying concepts using google. Somehow, for a course that one takes for pleasure and learning, this kind of time consumption becomes a problem. I will definitely take this course again but after brushing up on some basics.

I had no prior experience with the subject so I walked in not knowing much about what to expect. I was not disappointed with what I got. The course is extremely well developed and the professor has an aura of humility around him which made me want to pay more attention to what he said. The papers he assigned for reading were on the longer side and could get dry but I confess that I still found those papers really worth my while. I have not taken another social epi course anywhere yet so its hard for me to say how this one stacks up with other such courses. The quizzes were not always straight forward and required one to have at least seen the lectures and do a cursory read of the assigned papers to go through them. Not much to dislike here really. Good course and definitely recommended for people who have an interest in social sciences.

Monotonous and got really boring towards the end. It seemed the same concepts were being recycled every lecture and after a point, I don't believe I was learning anything substantially different. On the other hand, the ideology on which this course is based is an important cog in the health care system in mostly all countries and I did walk away with a greater appreciation of the kind of mechanisms that need to be put in place to provide access to care to everyone, regardless of social or economic status. Great effort but the course NEEDS to be made a little more biting. How that is to be done is a question I don't think I have an answer to.

Gamification is the new buzz word (along with Big Data) and thus I was attracted to this course. The course is well structured and provides a nice breadth of topics however as is the case with most MOOC's there is not sufficient depth, but this should not dissuade anyone from getting their toes wet with this class. Kevin is a reasonably enthusiastic teacher and I personally really enjoyed the peer review assignments we had to do.

This is an excellent course. The material is extremely fascinating and I personally believe has allowed me to look at the things I thought I knew in a different light. There are quizzes and exams (mid and final) but the content is right from the lecture so there are no great surprises. The lecturer is very learned and he clearly cares about what he is teaching.
