I also agree with NeonBlack and Creativ3. Exposing someone to more arcane knowledge or potentially dangerous tools before they are ready for it is the way to get them into trouble.
The military, for example, don't throw a loaded machine gun to new recruits on the first day. They actually take them through cleaning an unloaded gun, checking it is unloaded, and a few other things before ever handing the student a bullet.
The most effective teachers I know start simple, teach good habits, but also let the student believe things are a little less flexible than they really are. Once the student is better grounded with the basics, those teachers then point out the minor omissions (eg the more advanced techniques) and explain both the reasons the things were omitted before and why the student is (now) being exposed to them.
The least effective teachers I know insist on dumping all the advanced material on the students in no particular order - and they are often more concerned with demonstrating their own knowledge rather than helping the student learn.
Most people, naturally, fall between those extremes.
