This is quite common in work places. My contract clearly states that any and all materials created, conceived, proposed and/or any concepts created or that are a result works/projects carried out during working hours, on a company site or using company equipment are the sole property of the employer.
I have heard of similar things being the case in some American universities (known as the Facebook clause).
I would look very carefully at any contracts and or terms and conditions of the course and see if anything in mentioned ref copyright ownership. If there is nothing listed, I would speak to the education center's administrator to clear the matter up.
