Heterogeneity, diversity, and inclusion dictate the rhythm of a changing
society and, thus, demonstrate the challenges educational institutions
face. This also applies to teaching English as a foreign language, where
teachers are encouraged to meet this challenge with specially tailored
learning arrangements. Therefore, Maria Eisenmann not only introduces
theories of heterogeneity, differentiation and inclusion, but also
presents individualizing methods and learning strategies for the
practice of teaching. The author describes methodological options and
many innovative incentives for internal differentiation enhancing
learner involvement, learner centeredness, and learner autonomy.
