When I was At Prudhoe High School Community, I learnt that sometimes, students must improve their knowledge and autonomy for increasing their English skills.
Playing badminton, students must know as many rules as they can, for increasing their practice time.
Otherwise if they only pass the shuttle to the other field, they are not playing badminton, they are only spending their time. They must pass the shuttle to the free space, to the weak side of the opponent, or they must increase their tactics knowledge.
Only when they get involved into the match, with tactics hits, they can think and play.
Here we have an example of their active time in PE English lessons at IES Alonso de Orozco.
