Kinds of lessons

[English Freak]

We can categorize lessons in different ways, I think. One of them is putting them into two categories.
1. Practical Lessons (lessons in which we can learn better by practicing and doing experiments)
2. -------------------------- (those kinds of lessons that we are just supposed to memorize)
This is my question, what kind of lessons are they? Are they theoretical lessons?
Thanks for your help.

I don't think that all lessons can be categorised in this way. However, science lessons in my day, many years ago, were split between Theory Lessons, in which we were taught the why and how, and Practical Lessons in which we performed the experiments.
