Is the word educativo the same in Brazilian and European Portuguese?

Yes

The spelling, meaning, and grammatical function of "educativo" are identical in both Brazilian and Continental Portuguese. The only difference is pronunciation. In Brazilian Portuguese, the vowels are pronounced more openly and clearly. In Continental Portuguese, unstressed vowels undergo significant reduction, meaning the unstressed syllables are pronounced much more quickly and the vowels often become nearly silent.
