While there is a growing body of Critical Terrorism Studies (CTS) literature devoted to empirical examples and conceptual development, very little has been written about how to systematically carry out this kind of research. Critical Terrorism Studies fills this gap by addressing three key themes:The position of terrorism studies and critical terrorism studies in the discipline of International Relations (IR)Theoretical and methodological elaborations of cr

• Sommario/riassunto: Neste livro, a autora pensa a sala de aula como uma ocupação que transborda a aula para a esfera pública. Para isso, a autora narra a experiência de convidar artistas contemporâneos a ocuparem o espaço da escola pública de base com suas "obras de arte" e seus desdobramentos. A partir dessas experiências, justifica a ideia de "uma aula como ocupação" e reúne as falas das crianças escutadas ao longo desse processo. Nesse sentido, propõe que o ensino de arte na escola se reinvente permanentemente e se afaste do perigo da instrumentalização da arte e da infância.
