The article outlines peculiarities of the paradigm of fundamentalization of education in pedagogical higher educational institutions (HEIs) of Ukraine on the basis of the concept of sustainable development, namely: 1) performance of three interconnected functions of education — training, education, development; development of students’ ability to understand and implement sustainable development strategy in their future professional activity; 2) compliance of the paradigm with modern principles of structuring scientific knowledge, which are based on the internal logic of science, its place and role in the development of civilization in the 21st century; 3) ensuring the integrity of knowledge by integrating it around the core of fundamental scientific concepts; concentrated presentation of the fundamental laws and principles of science from a single methodological position, which allows building bridges between different subjects, without destroying their subject certainty; 4) formation of the theoretical type of scientific thinking of students; creation of intellectual, ethical and cultural foundation for personal self-development; 5) knowledge of modern information and communication technologies; oral and written communication in a foreign language. To acquaint students with the latest scientific achievements of mankind, the teacher must constantly “keep abreast” of socio-economic and environmental achievements of civilization on the basis of sustainable development, transform them into the content of the subject, as well as develop quality teaching and methodological support for its further understanding by future specialists. Given the rapid reduction of time between the invention and its widespread use, the content of subjects quickly becomes obsolete, which causes the inevitable lag of professional training of students behind the needs of modern society. To trace the synergy of humanization and ecologisation in the context of the fundamentalization of education on the basis of sustainable development, we studied the curricula of a number of pedagogical HEIs of Ukraine, namely: National Pedagogical Dragomanov University, Oleksandr Dovzhenko Hlukhiv National Pedagogical University, Volodymyr Vynnychenko Central Ukrainian Pedagogical University, Rivne State Pedagogical Institute, Ternopil Volodymyr Hnatiuk National Pedagogical University.

The article discusses the meanings of life and value priorities of the post- Soviet society. The author argues that, at present, there are symptoms of a global ideological crisis in the world, that the West does not have its own vision of where and how to move on and has no understanding of the future. Unfortunately, most of the post-Soviet countries do not have such vision as well. In these conditions, there are mistrust, confusion, paradoxical manifestation of human consciousness. The main meanings that determine our life-world are: the desire of citizens for social justice and social security, the desire to figure out and understand the basic values of modern society, how honestly and equally the authorities act toward their fellow citizens, and to what extent they reflect their interests. The meanings of life, which are the answers to the challenges of the time, are embodied in the cultural code of each nation, state. The growth points of new values, which will become the basis for the future sustainable development of a new civilization, have yet to be discovered in the systemic transformative changes of the culture. In this process, the emergence of a new system of values that governs human life is inevitable. However, modern technology brings new troubles to humans. It has provided wide opportunities for informational violence and public consciousness manipulation. Nowadays, the scenario that is implemented in Western consumer societies claims to be the dominant scenario. Meanwhile, today there is no country in the world that is a role model, there is no ideal that others would like to borrow. Most post-Soviet states failed to advance their societies to more decent levels of economic development, to meet the challenges of the modern information age, and to provide the population with new high living standards. Therefore, in conditions of growing confrontation, we should realistically understand the world and be ready to implement changes that will ensure sustainable development of the state and society without losing our national identity.
