A student teacher internship allows you to gain some teaching experience after you graduate from your university education program. In a student teacher internship, you start by observing a teacher in their classroom and then host small sessions with students. Your responsibilities gradually expand to include teaching students according to predetermined lesson plans and performing research regarding teaching methods and curriculum. You must learn the methods necessary to teach and create lesson plans and assist the teacher who is supervising you. Other duties may include grading student assignments, maintaining student grades and records, hosting one-on-one sessions with students, and meeting with your supervising teacher and other school staff to receive performance critiques.
