Using media in the classroom between Croatia, Sweden and Germany This thesis presents which media they use in teaching in three countries: Croatia, Sweden and Germany. Theoretical part of the paper describes the media, their classification, multimedia in teaching and briefly about the education systems of the mentioned countries. The study was attended by classroom teachers, and the purpose of the graduate thesis was to determine if the teachers of Informatics use media teaching in several cases than the teachers without Informatics, as it is assumed that the media is more accessible if students have IT as a subject. In addition, it was to be noted that teachers from these three countries often use media, which media use them, which pupils and for what purpose. The survey was conducted on 60 respondents, of whom 20 were primary teachers in Croatia, 20 respondents from Germany and 20 respondents from Sweden. Most respondents in all three countries do not have IT in classroom, but they are using media in all teaching subjects. Also, it is not confirmed the assumption that students with Informatics as a subject use more media in the teaching of teachers without the teaching of Informatics. With regard to the age of respondents, it was not established that younger teachers use technology, and all because of Sweden, which is the result of the most developed in terms of media types and their use in teaching.
