The book is a collection of critical reviews that are essential for teacher training. The texts in this collection deal with themes that are important to the academic world. They are dialogues with theories and knowledge constructed by different authors with a view to contributing to the training of teachers in this century and to innovating their pedagogical praxis. In this work, we bring to the focus of the dialogue texts such as: 'Beyond Abyssal Thinking: From Global Lines to an Ecology of Knowledges' by Professor Boaventura de Souza; notes on 'Conscientisation: Theory and Practice of Liberation: An Introduction to the Thought of Paulo Freire; Edgar Morin's 'Seven Knowledges Necessary for the Education of the Future' and finally a contextualisation of teacher training: 'Teacher Training in the Context of the Pedagogical Proposals of Rudolf Steiner (Waldorf Pedagogy), Maria Montessori and the Escola da Ponte Experience' by Evelaine C. dos Santos.
