You have never thought about that
Integrating language skills is time-consuming
It is difficult to find appropriate situations for some grammatical items
Other reasons (please, specify)
This question is asked to find out the reasons why teachers do not integrate language skills when they teach grammar. Obviously, no teacher answered this question as they all integrate language skills when they teach grammar. However, a teacher wrote a remark that he uses them (integrated skills), but it is time consuming. That means he hesitated between “YES” and “NO” for the 5th question, maybe because he uses them but not frequently.
