This book deals with the issue of non-native language instruction of content subjects in a Czech secondary education environment. This topic is viewed upon through the prism of Content and Language Integrated Learning (CLIL). The question is raised whether or not such an approach is feasible to be used in ordinary educational settings; which is addressed in the analytical part, which examines a CLIL project that was conducted previously. While discussing World War One, it combined the instruction of English and History. Do only exceptional students benefit from demanding projects, such as CLIL? Should these project be conducted despite the threat that the majority will not be able to appreciate them? Is really "one man worth ten thousand?" Or are we asking the wrong question? All of these and some more questions are tackled with in the book you just hold in your hands.
