Everyone has the right to education. The main objective of any education system in a democratic society is to provide quality education for all learners so that they will be able to reach their full potential and contribute meaningfully to and participate in that society throughout their lives. With the publication of the Education White Paper 6 in 2001, South Africa proclaimed its policy of inclusive education; however this policy is not always clearly understood by educators. Addressing barriers to learning provides relevant and in-depth knowledge to better prepare educators to teach all the learners in their class groups. Addressing barriers to learning covers the complete continuum of learners as reflected in the Education White Paper 6, and includes the most vulnerable of them: those who are economically and educationally disadvantaged, those with physical, sensory, intellectual, and/or learning impairment as well as those displaying challenging behaviour who are at risk of exclusion. Case studies offer practical examples and activities provide hands-on experience regarding classroom practice and management, collaboration with all role players and mobilisation of community involvement, which is at the heart of true inclusion. Addressing barriers to learning is aimed at both prospective and current educators.

Addressing barriers to learning is aimed at both prospective and current educators and other support professionals, including psychologists and therapists. The three editors, Emmerentia Landsberg, Deirdre Kruger and Estelle Swart, are acknowledged and experienced academics and practitioners in the field of inclusive education and accommodating diversity in inclusive classrooms.

Die Notwendigkeit wissenschaftlicher Erkenntnis der physikalischen und chemischen Eigenschaften der Faserstoffe als Grundlage fur ihre zweck massige Verarbeitung und Verwendung ist immer mehr erkannt worden. Aus diesem Grunde hat auch die wissenschaftliche Wollforschung in letzter Zeit einen erheblichen Aufschwung genommen, begunstigt noch durch die all gem-eine Entwicklung der Faserphysik, Chemie und Kolloidehernie der Ei weissstoffe, sowohl in theoretischer als auch in methodischer Hinsicht. Im vorliegenden Band wird erstmalig eine umfassende Darstellung des gegen wartigen Standes der Strukturerforschung des Wollhaares und seines phy sikalischen und chemischen Verhaltens gegeben, wobei die gesamte neuere und altere Literatur nahezu vollstandig berucksichtigt ist. Fur den Fach mann besonders wertvoll ist auch die eingehende und kritische Zusammen stellung der qualitativen und quantitativen Methoden zur Untersuchung der Wolle, allein und in Fasergemischen. Weiterhin werden die chemischen Verfahren der Wollverarbeitung von praktischen Gesichtspunkten aus be handelt, und in einem 2. Teil folgt eine eingehende, von zahlreichen Abbil dungen begleitete Beschreibung der maschinellen Hilfsmittel fur die mecha nische und chemische Ausrustung von Wollwaren. Dem Herausgeber der bis jetzt erschienenen Bande dieses Handbuches, Herrn Prof. Dr. R. O. Herzog, der inzwischen verstorben ist, verdanken wir auch die Entstehung des vorliegenden Bandes, auf dessen Zielsetzung und Ausgestaltung er noch bestimmenden Einfluss hatte. Den Verfassern der einzelnen Teile dieses Bandes sei an dieser Stelle der verbindlichste Dank ausgesprochen."
