This monograph reports on a longitudinal inquiry into mainland Chinese undergraduates' language learning experiences in an English medium university in a multilingual setting with a focus on their strategic language learning efforts. This book examines the issue as to what extent language learners' strategic learning efforts depend on their 'choice', if 'the element of choice' is the defining characteristic of language learners' strategic learning behaviour. The inquiry, using a qualitative and ethnographic research approach, reveals dynamic interaction between learners' agency and contextual conditions underlying the participants' strategic learning process. Such understanding informs pedagogical efforts to foster individual learners' capacity for strategic learning and their capacities in opening up and sustaining a social learning space for exercising their strategic learning capacity or utilizing their strategic learning knowledge.
