As supporters of learning and people interested in education you are likely to be seeking opportunities to keep learning yourselves. This might be to fill gaps in your subject knowledge, to allow you to perform your role more effectively or to follow a personal interest. FutureLearn run a number of online courses on many interesting areas, including education.
You can browse the available courses here: FutureLearn
The courses tend to be quite practical and involve online interaction with other people who are involved in the course. They are free to take part in although you can choose to pay to have a certificate of completion which may be useful if you want to use it as part of your CPD record or CV.
