I was a teacher in Wete, Pemba.  In my experience students very much wanted to learn English, but a main challenge was the language change from Kiswahili to English between Primary and Secondary school.  This was very difficult and intimidating for students.  Also, even many of the English teachers had trouble with English.

Changing the full education system will be hard, but having extra tutoring programs for english will be very helpful for students.  I applaud The English Improvement Centre for their efforts!
