Description: ML 4505/8803 and LING 4813/8803 explore second language (L2) acquisition/learning theory and foreign language teaching methodologies. The theoretical component (2 lecture credits) is conducted in English (mostly synchronic online via Zoom) and covers basic L2 theories, instructional approaches, and curriculum design. The practical component (1 lab credit) provides students with opportunities to apply their learning through a supervised teaching practicum, which include in-person classroom observation, tutoring, lesson planning, and teaching demonstrations in their designated language concentration (Chinese, English, French, German, Japanese, Korean, Russian, or Spanish).  Credits: 3 (2 lecture / 1 lab). This semester, we are honored to welcome two distinguished guest speakers whose expertise and experience will enrich our understanding of language teaching in real-world ESL (English as second language) and foreign language contexts.
