In this lesson, pupils can outline and explain the principle of each of these methods of machining materials. They can compare the advantages and disadvantages of unconventional machining methods with conventional machining methods.

The absence of pupils argues for the use of online distance learning (whether simply posted online by a teacher or using LMS systems), even in times when there is no threat of long-term school closures. Being able to use a distance learning course where everything is explained and the knowledge gained can be immediately tested and stored in long-term memory is very important for pupils. It also encourages the use of a method based on short and long term memory studies to ensure that pupils are learning.
