The issue that is facing many of our kids is that if they haven't got language, they can't carry concepts.
We want kids to 'Flourish' and part of it lies in understanding the brain (cognition) and concepts knowledge. But a key component lies in the attitudes towards the learning. When the learner loves language, this is difference making. Self-esteem matters greatly.
Another key idea Dr Jannie shared was that if we as teachers are not paying attention to the learners paying attention, we can not recognise purposeful engagement. Unless this is happening (photo) and we are optimising learning conditions, there is no learning happening.
