Flipped Computer Science classes

Computer Science (CS) classes have been supported for ten years by multimedia materials in the form of podcasts. Even such materials did not improve quality of learning outcomes. In order to change this the idea of flipped classroom (FC) was used but situation did not change radically, so survey concerning students opinion on FC was conducted. Comparison of results of survey show big differences in attitude to FC and learning between students in Poland and students in United States or Canada. Conclusion of this research is sad-it is very difficult to motivate Polish digital natives to learn..
