17. A consultant asks a trainee to assist in the operation of total abdominal hysterectomy. After several such operations, during which the educational experience of the trainee consists of observing surgical techniques, there is a rapport between the consultant and the trainee. The consultant then asks the trainee to describe the operation in order to ascertain that they have grasped the steps, techniques and use of instruments that are vital to a safely conducted operation. The consultant then assists the trainee in the procedure. After several operations with ongoing assessment, evaluation and feedback, the consultant and trainee are in a position to judge progress. The safety of patients is of paramount consideration. The trainee is capable of carrying out uncomplicated abdominal hysterectomy independently; consultant assigns the task to trainee to carry out the operation while assisted by another trainee. The consultant would be immediately available. What is the above technique?

Later this pair would discuss among other pair. And the group size increases to a certain limit, and then he bases further teaching on the knowledge displayed by the students.
