if i say i  want to know the effectivness of team work  on teaching grammar in EFL classes different from the effectivness of group work on teaching grammar

or the meaning is the same

 

i want to be definit because i �m going to write a resesrch about the teaming, the effectivness of teaming on teaching and i choose  grammar as apart of teaching . and i suppose team work means group work

 i think in teaching they  have the same meaning 

 

help me in this please  

 

i want to connect between team and grammar

Team work and group work are not the same thing.
In a team, everyone works together toward a common goal.
In a group, people work more independently.

If your paper is about team work, you should probably just write team and not group.

I hope this helps.
