Meta-cognitive Skills
Before requesting help from the teacher, pupils are encouraged to try and experiment with different strategies to see if they can reach the correct answer and to repeat this strategy with new questions to check its validity. These strategies could include using concrete material, drawing pictures, writing number sentenses or peer-assessment via discussion.
This is the core principal of meta-cognition, or "learning to learn", which can have a significant impact on pupil progress (see The Sutton Trust - EEF Teaching and Learning Toolkit).
Self and peer-assessment also promote self-regulation, whereby pupils are encouraged to manage their own motivation towards learning, to experiment and to try again.
