Following are few scenarios in a teaching set up. Choose appropriate T-L method.
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?
18. In the task of teaching ethics to a group of 12 embryologists for 2 hours. The teacher is unsure of their current understanding of the subject. He starts by getting the students, in groups provide them bit of information and asks them, to discuss the terms of the Abortion Act 1967 with each other. 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.
19. A teacher has been asked to instruct junior trainees on how to carry out diagnostic laparoscopy. The teacher initially shows the trainees how to assemble the laparoscopic equipment. No element of assessment and feedback was present. What is the above technique?
20. A teacher uses a tutorial on the anatomy, physiology and endocrinology appropriate to amenorrhea followed by a series of clinical cases including post chemotherapy amenorrhea, Turner syndrome, hyperprolactinaemia and complete androgen insensitivity syndrome. Where the students are asked to recall their learning from tutorials and apply to solve clinical problems. What is the above technique?
21. A consultant wants to teach examination of breast to a group of trainees. He is unsure of their present anatomy knowledge and wants to help them recall and which technique he would use?
