Experts - because of their expertise - are able to automate basic tasks, or processing, in order to free up cognitive space to tackle more complex aspects of a problem. They're also able to see patterns, and organize knowledge, differently than novices. For teachers, understanding the difference in how novices and experts think will help them support their students in stretching their knowledge and acquiring expertise.
while novices do think differently than experts, they can be helped toward expertise by being given challenging tasks for which the teacher provides a bit of support: reminding of what has already been learned, doing some of the lower level parts of the task so the student’s capacity can be invested in the expert elements, and even easing the student toward a more expert way of tackling the task
Being helped toward expertise is much better than just being drilled on novice performances.
