Indeed. This is explicitly mentioned by the Rav, RYBS zt"l in some of  
his comments on the Parsha as recorded by Rav Hershel Shachter.
Namely, that Onkelos listened in and learned from the lessons given to  
the Tinokos Shel Beis Rabon by their Melamed/Rebbi.
That Melamed was transmitting the oral mesora from sinai in his  
translation/basic explanation. Onkelos served to record these
in Aramaic
