Stef came to watch me teach a level 1 class on wind power and I observed Sarah’s on-line course on pre-hospital care for people with long term conditions.
My students have already had an introduction to wind power in on of their first semester classes in preparation for a field activity where they collected data on public attitudes to wind power in North Wales. But this introduction focussed very much on public perception in relation to on-shore wind. We had not yet covered how wind turbine work and other challenges associated with harnessing wind power on and off shore.
So the purpose of the class was to provide them with an overview of how wind is generated, how much energy is in the wind and how that energy is then harnessed. The plan was to then go on to get the students to think about and research what the challenges in wind power development might be. The initial plan for the class was a more traditional lecture, but with a series of mathematical equations which the students had to solve to calculate things like wind power based on speed, wind at height and tip speed ratio. At the end of the session I planned to get the students to identify potential barriers to development based on the information given in the rest of the session, then share their ideas with the rest of the class.
Unfortunately my students are rubbish at turning up in time for 9am lectures, and we had a course evaluation to do. So I didn’t actually start teaching until 9:30. As a result I had to re-evaluate what I could actually deliver in the remaining time and still allow the students to have a break.
Timing
Timing was one of Stef’s observations. This is something I’ve always struggled with, but it probably stems from the planning of the whole module in the first place. One 2hr class is not enough to provide a full overview of wind power (or actually most of the renewable technologies, they could all be modules in their own right!). So how can I change this?
- Change the content: given that the Tory Government in its infinite wisdom and the “greenest government ever” plans to gut onshore wind subsidies, next year I can probably afford to spend less time on the issues and constraints of onshore wind. But this allows for more focus on offshore wind (which is apparently acceptable to the electorate). In fairness this may be a good thing, given the amount of off shore wind resource potential that the UK has. But then I’m not teaching just UK students. Onshore wind has great potential else where in the world and it is therefore important that students understand the benefits and constraints of both.
- Flip the classroom so that students do more pre-class work and the class focussed on discussion rather than me presenting information. This should also help develop the students research and digital skills, which was one of Stef’s other concerns. Being more traditional in style of delivery this class was very much pen, paper and calculator based. So at no point during the class did the strings use a smartphone, tablet or PC.
- Put less in and given them some very specific reading to do. Based on my analysis of the MOODLE reports my students don’t read a lot of what I post on the VLE or only read the first thing in the list. I probably need to explore why this is in more detail, but based on discussions I’ve had with my second years it may be because I provide too much information. Based on my discussion with Sarah where I “observed” her on-line course providing small, but critical chunks of information works well for those who haven’t studied for a period of time. I think that this principle probably hold true for first year students too. They are trying to make a transition back into academia as a mature student or away from a very prescriptive and dieted form of learning in high school. In both cases being bombarded with information is probably not as helpful as I think it is. It probably just confuses them and makes it hard for them to work out what is important. More reading could then be provided at a later date.
Increasing digital skill in class.
For this particular session I could develop a spreadsheet of data and ask students to model windpseed and power. I could (if I can find an app or get my paws on some equipment) also get them to collect their own windpseed data then do some modelling to calculate city centre wind potential…..
Another option may be to “gamify” the calculation part of class using Socrative space race. This way the students could work together to get the answer, it would force them all to work the answer through, as I’m not convinced all of them did the calculations. However I think one needs to be careful with this as while I like competition and research shows that it seems to add a lot to engagement, students also need to know that care needs to be taken, attention to detail is vital and that calculations should not be rushed.
Again, thinking back to Sarah’s online course I could also build some more interaction into MOODLE (while bearing in mind the point above about too much info!) such as a post class quiz, discussion/forum posts about the different technologies and how they are portrayed in the media. However as Stef pointed out sometimes there is no substitute for drawing on a big sheet of paper to help explain something. I was trying to explain atmospheric turbulence, created by buildings and forestry etc and its impact on wind power. The students weren’t following my verbal description and I didn’t have it on a PowerPoint slide, so I reverted to drawing on a flip chart. Which seemed to work well. But I could also have got the students to look up a diagram of video themselves then shared that.
Academic content & research informed teaching
The academic content (or lack thereof) in my lectures was one of the issues raised by my HoD in my last teaching assessment. So it has been an area that I’ve been trying to focus on. Stef felt that the content was good for this particular class, but it is something that I have to do more on. Renewable power is not an area that I am “research active” in, but there is plenty of data in this field. I just need to filter out what is too engineering focussed and may be too higher level of my students. Their focus is not on how to build renew able technology, but to understand how and where it can be developed, the key information needed to do so (and which experts to help you do so)and what the challenges in this will be.
Mental note to self….always make sure that you subscript or superscript your formulae! This will stop you from making embarrassing mistakes with equations in class that you can’t then work out what on earth you did to get your answer or what the students did to all get a different answer! Although this particular equation is best done in excel, not on a smartphone calculator….see point above.
On-line teaching
I really liked Sarah’s on-line course and it is something I’d like to try, possibly as an intro to the degree. But I’m going to save those thoughts for another “exciting” blog!
