The fields of linguistics and cognitive psychology have rendered theoretical models of first- and second-language learning and acquisition. Participants in this course examine how these theories apply in TESOL and bilingual education. Participants also examine the critical factors affecting language development. Among those covered are psychological factors such as motivation and communication strategies, sociocultural factors such as dialects and language policy, and pedagogical factors such as formal and informal learning. Participants draw upon their own language learning and teaching experience for examples that relate theory to practice.
