Following are some of the T-L methods. Identify the T-L method

10. A teacher wants to modalities to be used in a survey that he is planning to conduct with the help of the trainees. He invites them for a discussion about how to do it. There they invite the raw ideas, discuss possibilities without worrying too much about its correctness. Later they sort and prioritise the discussion findings that are recorded on a flip chart. What is this mode of T-L method?

11. A teacher was unsure of present knowledge of students on management of premature labour. He gives instruction and questions to one person and ask them to think alone and later discuss in pair and extend the discussion with group of four and then the group of eight. He allows for the discussion to escalate with the varying knowledge level of students. What is this T-L method?

12. The teacher asks the students to prepare a case of pheochromocytoma in pregnancy that is so rare but they have recently seen in practice. And then ask them study about its aetiopathogenesis and management in a group discussion. What is this type of T-L method?

13. A teacher prepares a book which is informative, integrated, interesting and interactive and help assisting in the management of student learning, providing a focus for student activities relating to learning and also providing information on the topic/subject to study. What is this T-L material called as?

14. A clinician demonstrates per vaginal examination to a group of students. He does not give any description. There is no further discussion and the students are allowed to observe the procedure. What is this teaching method?

15. A clinician allows a first year trainee to assist him in cesarean section. He while performing explains the procedure and the trainee is allowed to observe. In subsequent operative procedures the trainee is asked questions on his understanding and his knowledge is judged. Later he is allotted to perform cesarean along with the surgeon in place. And the assessment and corrections happen. Later the trainee is allowed to perform section with surgeon on call. What is this T-L method?
