Sommario/riassunto |
|
Laser ablation is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam. This book presents research in the study of laser ablation. |

Sommario/riassunto |

Für die Umsetzung von gesellschaftlich notwendigen Transformationsprozessen wird Bildung eine Schlüsselrolle zugeschrieben. Mit den Konzepten Bildung für nachhaltige Entwicklung |

|
(BNE) und Globales Lernen wird der Anspruch verknüpft, zu globaler und sozial-ökologischer Gerechtigkeit beizutragen. Dass sich die Praxis dabei auf grundlegend unterschiedliche – und umkämpfte – Transformationsverständnisse bezieht, arbeitet diese qualitative Interviewstudie heraus. Transformation wird als Bildungsprojekt und Bildung als Feld und Strategie von Transformation thematisiert und analysiert. Deutlich wird, dass Globales Lernen/BNE immer als verwoben mit bestehenden Macht- und Herrschaftsstrukturen verstanden werden muss, wenn sie einen Beitrag zu einer kritisch-emanzipatorischen Subjektbildung leisten will. |
