The Microsoft Educator Center provides a great, free way to upskill yourself as a teacher

I have just earned my '21st century learning design: Introducing 21CLD' Course 1 badge on the Microsoft Educator Center! It introduces the six important skills for lesson planning, namely collaboration, communication, ICT skills, self-regulation, knowledge construction, and real-world problem solving and innovation.   This first introductory course provides the background leading to the selection of these specific skills. It is very interesting!  The others enlarge on each skill separately.  Here is the link for the first course:  https://education.microsoft.com/course/8220d07e/overview 

The Microsoft  Educator Center is full of relevant, free professional development courses for the modern teacher. Take a look: https://education.microsoft.com/en-us
