The Training and the Praxis of the teacher from the Materialist Dialectic, the Cultural Historical Theory and the Critical Historical Pedagogy is the title of this dossier, which proposes to analyze contemporary themes that deal with a critical look at society, education and human training, in order to resume the contributions about dialectical thinking. It intends to discuss the formative processes that involve the school as a social institution responsible for socializing the knowledge produced by humanity, aiming at a quality education that can reverberate in the development of critical thinking of the subjects involved in the process about the objective reality. The texts are based on the Critical-Historical Pedagogy and the Cultural-Historical Theory, and mark their position by pointing out that the enrichment of human existence in its omnilateralism is a process of active and conscious appropriation, by the individual, of the cultural resources present in the environment and the value of interaction between student and student, student and teacher.

In this article we present and discuss the value of the ethical dimension present as articulator in the organization of pedagogical work. Whereas Ethics is disfigured by the events and understandings of today's society, in which teachers hide behind masks as proletarians of unnecessary knowledge and useless to capital, analyze the ethical dimension and its importance for the process and educational practice presents itself as an appreciation of the human being and all its manifestations. Understanding the School as a space for interactions, the curriculum becomes a cultural artifact for the teacher to achieve his goal with a humanizing education that aims at the emancipation of the human being.

In recent years, the penetrating social influence of digital media popularizes teaching methodologies, proposals and recipes, which, in many cases, lack academic credentials to justify its validity, or even, have already been refuted by the scientific community, becoming in mere educational hoaxes. Given this current reality, this research article reviews and reflects on the training of teachers (general and of science) proposing that it should be based on accredited research results, to achieve high educational standards. The proposal is articulated around several educational elements: some, contributed by the didactics of science, such as scientific and technological literacy, education in context and training model of science teachers, and others, contributed by general educational research, such as professional teaching knowledge, test-based research, cognitions, educational neuroscience and critical thinking. The reflection emphasizes the themes and needs shared between these elements, proposing the concept of critical literacy, which is developed in a taxonomy of critical thinking skills, considered essential for teacher training in the digital information space, common to all current education. Finally, an empirical model and some general features are suggested, such as the integration of knowledge and the development of critical thinking skills during teacher training, to meet current teaching and learning requirements in relation to critical literacy in science and technology.
