Course: Respiration in the Human Body
Length: 7 weeks (self-paced)
School/platform: Université catholique de Louvain (Belgium)/edX
Quote:How do we breathe? What is the purpose of our lungs? What is the link between oxygen and life ? These questions open a vast field of discovery to help us understand respiration. This course is for anyone who wants to understand human respiratory physiology, the operation of respiration and the lungs.
…During the course experts will discuss specific and practical topics such as how to comprehend oxygenation of a patient, why and when to administer oxygen, and what hyperventilation means.
This course will also discuss in depth human anatomy, physical volumes and pressures of gasses, blood, oxygen, CO₂, lungs, tissues, smoking and chronic bronchitis.
No, the Belgians don’t breathe any differently than the rest of the world. But they sometimes do make MOOCs partly in French, like this one.
There is an all-French version of this course. I’m not sure why they decided to rework it for speakers of English – the videos are in French, but the captions, transcripts, and all text materials (including very helpful formatted handouts with embedded images) are in English – but I’m very glad they did, since I just love medical stuff. There were a few weird translation moments, and it did take a slight extra effort to coordinate words and images, but it worked fine.
Respiration is, alas, about half math and physics. It was kept very simple in this class, with basic explanations of pressure, diffusion, and maybe four basic formulas, none of which involved anything more complicated than multiplication and addition. Things still got kind of complicated, because there’s a difference between the pressure of oxygen in the blood, and the content, and then there’s always figuring out which of several values is altered when altitude is increased, when submersion is involved, or when simultaneous conditions, like asthma or anemia, are present. Then there’s some extra challenge when occasional European conventions, like using commas instead of decimal points, show up.
The course is self-paced, so all five modules were released at the start. The first two cover the basics of plain vanilla respiration, while later modules add in things like altitude shifts, effects of pulmonary diseases, pregnancy and fetal respiration, and pollution. Each section of a module (usually four sections) include a single video, which is mostly lecture with a few health-worker interviews sprinkled in. The lectures were clear and very well-presented; the interviews, not so much. Several of us took exception with the first lecture which proclaims life is not possible without oxygen; there is a sense in which that’s true (human life as we know it, say), but there’s also a sense in which it’s nonsense, since life existed on earth before there was oxygen. In fact, life created oxygen. But that’s a quibble.
Each section also contains several graded “homework” questions. Most are multiple choice, but there’s usually at least one “post your answer” question per section: pick a location at altitude and show what it does to arterial oxygen content, or describe some pollutant and its effects on the body. These are honor-graded, as in, did you do it, check yes or no. The midterm and final, each worth 20% of the final “grade”, are peer-assessed and in similar vein (oops, Freudian pun) to the “post your answer” questions. Passing is set at 50%, “excellent” at 70%. I’m not sure why they have such low expectations. My final hasn’t been assessed yet (I’m not optimistic, since I misunderstood a couple of the questions) but I’m already over the “excellent” mark.
Staff coverage of the discussion boards was very limited. In the first week, a technical issue was quickly resolved, but content questions were largely unanswered or involved long delays (two weeks). This may be due to summer vacations, or to the general trend of moocs as standalone and unsupported (a trend that dismays me greatly). It felt to me that there was generally less student participation than I’ve seen in other medically-oriented courses. Typically, a couple of students will have advanced training in technical areas and will be able to offer help, but that didn’t seem to happen here. It could be the time of year, or it could be the language issue. It could be the constant stream of forced posting that always dilutes actual communication, though someone in moocland thinks it’s a great component.
I wouldn’t say it’s an easy course, particularly for those of us who are permanently mathematically confused. But it’s very do-able. It’s also not the slickest mooc on the block, but I’ve seen some very slick moocs that were crap. It works; with a little bit of accommodation it gets the job done. While it might be too much trouble for someone with casual interest in respiration, I’d recommend it for someone who wants a basic understanding of what actually happens when we breathe.
