In "Towards a systemic theory of gifted education," A. Ziegler and S.N. Phillipson have proposed a systemic approach to gifted education. For this approach, they built a model that they call an "actiotope" model. As they explained in the article, an actiotope consists of the acting individual and the environment with which he or she interacts. The model includes four necessary elements: (1) action repertoire; (2) goals; (3) environment; and (4) subjective action space. These elements are interdependent with each other, co-evolving to reach a dynamic equilibrium. Here, the actiotope model describes all the factors a perfect system needs to work well. In current studies of giftedness, it has heretofore been difficult to find a theory that takes all these factors into account and builds up a perfect framework for developing giftedness. Most researchers focus on either cognitive or non-cognitive abilities. After many years of research and education experiments, however, researchers and educators realize the great necessity of reconsidering human nature in its entirety. The reviewers agree with the systemic view that excellence is the product of a system. The idea of system theory has appeared in various fields and has a relatively long history. Theoretically, the systemic approach is acceptable to most researchers and educators; they do view individuals as a whole. In practice, however, researchers often decompose the individual system into different parts, such as memory, language, reasoning, creativity, and emotion; it is practically very difficult for educators to maintain a holistic approach to individuals' aptitudes. Because researchers themselves are limited by research methods, they can investigate only limited variables and cannot promise that even these variables will always, or even commonly, work in real systems as they performed in the studies. Perhaps the mere fact that Ziegler and Phillipson's approach considers so many factors, compiling them into a system, makes their approach difficult to put into practice. This is the biggest objection to the actiotope model: it's good--but too good to implement. However, with the demonstrated improvement in methodology, the appearance of the structural equation model enables researchers to consider many factors simultaneously in order to test whether their systems (theories) are right or not. At the same time, the structural equation model can separate the effect of one factor from the whole. Nowadays, a number of researchers apply a similar method to their research. The actiotope model gives an excellent example of the systemic approach. The reviewers believe that the systemic approach will be the ultimate choice in gifted education and research.
