📝 Source Credibility and Note Codes

Using sample interview transcripts, multilingual flyers, a legal FAQ, and a short case vignette from day 1, students learn a common annotation system for source type, origin, purpose, bias, and reliability. The teacher models an evidence tracker and note-taking shorthand, then students practice coding one source and logging it in their Immigration Investigation Research Notebook. This gives teams a shared method they will use in later phases.
