What is the meaning of 教训 here？ A very good fisherman taught his 3 sons his technique but he did not teach them 教训。 What does this 教训  mean here?

Earlier, in the text, it says: 


  可他三个儿子的捕鱼技术都很平庸。
  
  别人告诉他：“你只传授给儿子们捕鱼的技术，却没有传授给他们教训。 没有教训与没有经验一样，都不能使人成功！”
  
  教训：   
  
  
  指从错误或挫折中得到的经验  
  教育训练  
  训导;训戒  
  


I don't think this 教训 is 3. That leaves either 1 or 2. 

The person said, "你只传授给儿子们捕鱼的技术", so the father taught them the technique. Maybe this 教训 here means 'training'? He taught them, but he did not train （训练） them?

Or 却没有传授给他们教训 means: 


  but you did not teach them what you learned from your mistakes"
It's 1, you might feel awkward or unfamiliar because:

When we take the meaning as 1,
we seldom says that someone teach others "教訓".

A more often way to use this meaning is to learn by someone itself.

Ex: 我從上次的失敗吸取教訓了，下次不會再犯同樣的錯。

I'v learned my mistake from last failure, and I won't make it again.
