Assess the candidate's ability to design an original, research-grade annotation schema and accompanying corpus for analyzing multimodal translanguaging and disciplinary literacy practices in bilingual STEM higher-education classrooms. The task should test theoretical grounding in translanguaging and disciplinary discourse, specification of annotation layers (linguistic, semiotic/modal, interactional, translanguaging moves), unitization and label inventories, hierarchical relations and span alignment, metadata and sampling across STEM disciplines and languages, annotation guidelines with examples, inter-annotator reliability and validation plans, ethical/data-management procedures, toolchain and interoperability choices, licensing/reproducibility, and proposed research and pedagogical use cases with sample annotated excerpts.
