 It is inevitable when you're teaching a large group of people that people will be coming in with different amounts of knowledge, they'll be up to different points in understanding. So when you're teaching you've always really packed for time and I see flipping as a great way of making up a bit more time in the classroom. If you do some stuff out of the classroom you can then do more hands-on activities, more practicals, more labs. The Mary Sam Project leverages the enthusiasm and expertise of ANU academics, staff and students. It volunteers to create curriculum-aligned videos and activities. These resources relieve the time pressure on teachers to create content for their class, freeing them to be experts in building STEM skills with their students. Mary Sam's resources have been readily adopted in public, Catholic and independent schools within the ACT and in states across Australia.
