MGML-Methodology To provide area-wide basic education, INES conceptualizes a school system which is mobile and activity-oriented. The learners – not the teachers – organise their learning process with the help of so-called ladders of learning. They learn material-based, individually in heterogeneous learning groups. This approach is based on the MultiGradeMultiLevel-Methodology, which was developed in the 1980s by an Indian teacher couple (Padmanabha and Rama Rao), and on reform pedagogical insights and materials by Maria Montessori. The MultiGradeMultiLevel-Methodology is described in the German book “Lernen mit Lernleiter” and its English version “The MultiGradeMultiLevel-Methodology and its Global Significance” (Girg/Lichtinger/Müller 2012; ISBN 978-3-934575-52-3). This publication by Theresa Schaller and Ruth Würzle (2021) deals with the necessity and the development of a mobile school system for mobile pastoralists in Northern Kenya. The underlying system Ladders of Learning guides learners and teachers with a reliable framework for individualized learning and community-oriented education. The book gives a practical insight into international cooperation, curriculum-based learning material development and flexible teacher education in the INES project of the Benedictine Fathers in Illeret.
