# ...a student who.... / ....one student who..... / ....a particular student who..... / .....one particular student who

This is from a native speaker's training video on classroom management:

"How can you deal with one particular student who is determined not to listen?"

I wonder if it is really necessary to say "...ONE PARTICULAR student...", whereas simply "...a student who..." would suffice, because it is followed by a relative clause ("...who is determined not to listen"), so there is no chance that "a student" would be too generic.

Similarly I also wonder whether we need to use "ONE PARTICULAR", because it seems that all of the following would work, as it is followed by a relative clause. So, I think that all of the following would mean the same and will be quite clear:

1- "....a student who ....."

2- "....one student who ...."

3- ".....a particular student who ....."

4- ".....one particular student who....."

So, do we need to use "....a particular student who ..." whereas simply "...a student who ...." would mean the same?
