"Values without knowledge are blind, while knowledge without values is irresponsible." This principle underlines the motivation to write this book. It presents VaKE, Values and Knowledge Education, a theoretical model based on constructivist learning theories, and many examples for its practical implementation in diverse educational fields. Thanks to its extensive theoretical foundation, the model opens up almost unlimited possibilities to tailor the course to the needs of the participants and to the dynamics of a process. The justification of ethical values is attributed a general importance for the development of personality as well as for the thriving and flourishing living with each other in a society. School education aims at providing respective knowledge. However, this knowledge is separated from the subject matters, whereas for its application in daily life both - knowledge on facts as well as on values - are necessary and indispensable for evaluation, assessment and decision making.
