Language is a form of communication. If you don't or can't speak the language one understands very well to the bone, you are not communicating. And the person is not understanding fully. Which leads to limited information and knowledge being transmitted.

If you take a look at many countries, especially better developed ones. You will notice that they do almost everything in their native languages including teaching at schools from kindergarten to university level. But in Nigeria, students struggle to understand basic concepts at school due to the lack of good command of the foreign language "English" we exalt.

Come to think of it, even countries like China, India, Brazil and many European countries teach their students in their native languages. Some people in Naija will even mock you, that you cannot even speak "Good English". Do not get me wrong. I think English should be taught as a second language for business usage worldwide.

Do you think academic performance will improve should textbooks be written and lectures be held in our "pidgin or native languages" which everyone understands better ?

While it is true that language is a form of communication, pidgin english is still not our official mode of communication in Nigeria and therefore, it should not be used to teach in our schools. http://www.infobarrel.com/Good_customer_relations_as_an_important_factor_in_growing_a_business
