What experience involves a teacher-in-training practicing teaching under the guidance of a veteran teacher?

The experience described involves student teaching, which is a critical component of teacher education programs. During student teaching, a teacher-in-training works directly in a classroom setting under the supervision and mentorship of a veteran teacher. This hands-on experience allows the trainee to apply the theoretical knowledge gained through coursework in a practical environment, interact with students, and develop instructional skills. The guidance provided by the veteran teacher is invaluable, as it offers personalized feedback and support that helps the trainee refine their teaching strategies and classroom management techniques.

Other options, such as student assessment, classroom observation, and professional development, serve important roles in a teacher's growth but do not embody the same direct, immersive practice under the mentorship of an experienced educator that student teaching provides.
