Felix has competence with the skateboard. He can do it.
He can do it rather well. He has learnt how to do it.
The edu-twitter fanatics want to know if this is due to skills or knowledge.
They do want Felix to have competence, BUT it is far more important for each side to win the skills or knowledge shouting match.
SKILLS! KNOWLEDGE! SKILLS! KNOWLEDGE! SKILLS! KNOWLEDGE!
Competence = the mix of skills and knowledge to do something successfully.
Felix is competent! He doesn’t waste his time with pointless Twitter arguments.
