Michaela Kuhlmann presents the IntraActPlus concept for learning to read and write in this essential guide. Originally developed for children, the author demonstrates that it also yields remarkable success when working with adolescents and adults. She describes what needs to be considered when teaching adults from diverse backgrounds using this concept. The essential guide originated from a volunteer literacy course for 19 refugees at the adult education center. The participants were unable to speak or understand German, making communication nearly impossible.
