Promotion of development is a basic task of educators which concerns not only definite people but also communities and societies in which educators work.
Citizenship education both formal and informal gives space for development of social skills necessary for living in the modern world. One of such skills is respect for diversity which in its essence undermines prejudices. Representatives of different social groups can contribute into development of communities and societies if they are given opportunity to develop themselves. Prejudices brought by some educators into education activity hinder personal development of representatives of disadvantaged social groups and consequently hinder development of communities and societies.
Modern societies encounter quick changes which require quick adjustments. These changes lead to diversification of societies and communities. Global businesses, availability of information and travelling require development of skills concerning tolerance to diversity. In such conditions educators need both to develop such tolerance in themselves and spread it through their teaching activity among pupils and students. Tolerance to diversity can encounter ideological, religious, gender relations, etc. norms widely spread in definite communities and societies. So dealing with such norms will require much tolerance itself and development of skills in changing such stagnated norms for the sake of development on the levels of a person, a community, a society and global human civilization.
In modern global world development of people, communities and societies becomes impossible without respect to diversity. Prejudices, on the contrary, lead to stagnation and isolation and as a consequence to degradation. Changing stagnated norms require much time and efforts when it goes in evolutionary way without violation of human rights.
