Standardising Methods in Bricklaying

In the construction industry, predominantly bricklayers, as this is where the author’s specialty lies, there are varying methods and techniques that bricklayers use to get the same results; for instance, building a straightforward wall, a bricklayer might spread his mortar differently from another bricklayer but get the same result and no method is better or incorrect as they achieve exactly the same outcome.
But when this is transferred to a learning environment, you can see the potential problem.
If there is a group that is taught by two different teachers, and they have different methods, this can lead to confusion within the group which is what is happening with the groups I am involved in.
