That depends really on which country you are from.
In some countries education believes in using industry languages for education, while some other countries choose languages based on educational purposes. In some countries it depends on the school/college.
Both cases have their arguments for and against (including that industry languages training most benefit big business that can use cheap graduates with minimal training and might have changed anyway when students graduate/after that initial job, and counter argument that the educational purposes argument in practice often degrades to teachers not having to less frequently update/rewrite their courseware than actual educational benefit )
