This book presents a form-function mapping (FFM) model for balancing language and content gains
within content-based language teaching (CBLT). It includes a theoretical part which outlines
the FFM model and drawing on the analysis of eclectic teaching methods and interlanguage
restructuring proposes pedagogical tools for its implementation. These tools which encourage
mapping of language forms onto content knowledge are hypothesized to facilitate interlanguage
restructuring thus helping CBLT learners in their struggle with L2 morpho-syntax. The
empirical section presents the results of a quantitative-qualitative study conducted among
adult L1 Polish learners of English in a CBLT context. It then goes on to translate the
findings which reveal that the FFM model has a positive and significant influence on
interlanguage restructuring as well as a favorable reception among CBLT learners into a set of
pedagogical guidelines for practitioners.
