Strumming the fingers across the strings and using the whole arm encourages a free arm-steering action. It is good to relate your repertoire at different stages back to the fundamentals of violin technique that you learnt in the early stages.
The A Minor Concerto by Accolay is a good example of use of the whole-arm arm steering action.
