Pedagogo, Docente e Investigador, is a work of daily use for group teachers, regardless of the educational level where they work. This book integrates ideas, analysis, reflections and essays on the philosophical and pedagogical foundations of the teaching practice; going through the linguistic bases of the writing of educational texts, where semiotics and hermeneutics play roles of great relevance for the perception, understanding and explanation of the ideas that found teaching in the classroom; both in its intro and exo scope. Scholasticism is used to trace the contributions of St. Augustine in relation to memory, forgetting, narration and the five senses as intermediaries between our body and the sociocultural environment. Likewise, texts on corporal existence and the teaching habitus are incorporated where polemic, controversy and pedagogical debate take academic form. Signans and signatum are also integrated into this work as pillars of otherness and the representation of the other in the classroom environment. In short, it is a work where the reader will be able to situate himself between the pedagogical and philosophical thresholds of teaching practice.
