I feel textbooks and lecturs play vital role in our educational system. The only problem with an instructor who lectures all the time is it can grow quite boring.
Textbooks are sometimes to vague in subject area.
This is where a good teacher comes into play. A good teacher knows all the points of interest that need to be expounded upon. We also have to remember that no people are the same and all learn differently. If your entry does not appear after posting - click 'Reload' button.
