Evaluation Approaches and Their Fundamental Theoretical Principles

The science-based evaluation concept presented in the previous chapter and the CEval approach built upon it are procedures that, in terms of their theoretical foundations, have a number of things in common with other concepts and approaches, but also some aspects in which they differ from them quite markedly. Although evaluation research, as compared with most scientific disciplines, has a relatively short history, various development tendencies have already formed. These will be presented briefly in the section that follows, so that the approach developed here can find a place in the theory-of-evaluation discussion.
