Hi Clara: the last page you create is in Pedagogical_Trans(parent)Operations.
I removed the prefix
MPTpO: as this has a special meaning in wikiland, it stands for a Namespace a kind of descriptor for the type of page it is, for instance User:, Main:, Special:. And given that it is a normal wiki page it is better to a void the prefix.
