I have never known what these mean in the real world…” „I can recite the second law of Newton, but I can’t imagine where I can use…” „I couldn’t make contact between theories of science and my own world, and my own experience” Conclusion: Can’t see the koherncy between science subjects. Miss the reference to his/her earlier science knowledge among science subjects. We have a false idea about students’ prerequisite knowledge Our teaching method is academically, absolutly not learnerfriend
