The purpose of this paper is to explore the complexity of designing knowledge ecosystems for business education based on the theory of knowledge fields and knowledge dynamics. That means to change the paradigm of university education based on the traditional rigid curriculum into a new paradigm based on adequate knowledge ecosystems. The new paradigm reflects the needs of developing a personal learning environment in a volatile, uncertain, complex, and ambiguous (VUCA) environment. Business education should adapt its design to the complexity of the real business environment dynamics and to the need of strategic thinking. The present paper integrates results from a qualitative and a quantitative research performed in the period January-March 2019. Qualitative research is based on the critical analysis of literature dedicated to business education and on the theory of knowledge fields and knowledge dynamics. The theory assumes that knowledge can be understood as a spectrum composed of rational, emotional and spiritual knowledge fields which interact continuously. Each form of knowledge can be transformed in any other form of knowledge, as energy forms in thermodynamics. Thus, business education can integrate all of these forms of knowledge and develop a deeper understanding of the complexity of the real world. Quantitative research is based on a survey done with students enrolled in business administration program. We got 269 valid questionnaires and then we processed them by using the specialized software package SPSS. The knowledge ecosystem is conceived as a learning environment where students can benefit both of the university knowledge transfer and mind developing processes, and of internship programs in some companies which provide direct business experience for them. The design of the knowledge ecosystem considers also some other types of business activities like business clubs, entrepreneurship incubators, workshops and leadership summer schools. Strategic thinking integrates all these forms of knowledge and creates a support for long term decision-making.
