To provide fluency speaking practice in a small group in the context of health issues and treatments in students' childhood
Procedure (36-45 minutes)
T will ask questions to SS to set up the context Have you ever had an operation? if yes, were you awake during your operation? Do you go for a check-up with your doctor? Are you afraid of going to hospital? Then, T will show two pictures. -ask ss which one is in the past and which one is in the present to be able to lead ss into the " idea of past" and pass to the other stage.
ASK the students to find sentences with "could", "had to" and "didn't have to" by scanning through the text. Expected sentences are: 1) Anaesthesia: Before anaesthesia patients "had to" be awake during operations. 2) Antibiotics: Doctors "could" treat infections properly. 3) Germ theory: Before 1847 doctors "didn't have to" wash their hands before an operation.
T will write those sentences from text on the WB to clarify meaning: 1) Before 1847 doctors "didn't have to" wash their hands before an operations. CCQ: Is it about the future, present or past? PAST. Elicit the meaning "obligation" from students: CCQ: Was it necessary ( by law ) for doctors to wash their hands before 1847? NO. 2) Women in labour "could" be dying from infections...... CCQ: Is it about "ability" or "possibility"? POSSIBILITY BUT SS might overgeneralize by considering the past form of "can". THEN, OMIT "could" from the sentence and stick "were able to" paper and ask ss about the meaning: Women in labour "were able to" be dying (die) from infections..... -LET SS discuss for 1 & 2 mins with their partners about the meaning. THEN ASK; CCQ: Is dying an ability? NO. - MAKE SURE SS to grasp the difference in meaning.
- In-pairs , SS will discuss the rule than, T will elicit the sentence rules from the SS. S + COULD (MODAL) + BASE FORM S + AUX + NOT + HAVE TO + BASE FORM DID + NOT + MODAL
T will give HO1 including sentence completion with had to / could / didn't have to. It will be done individually , but checked in pairs. For Feedback, SS will open the folded part of the hand-out.
In pairs, SS will discuss about what people "could / couldn't or had to " do before these inventions and discoveries. They can refer to the text. For example: anaesthesia: Patients had to be awake during operations People could feel pain during operations. Sanitation: Death rates could rise without clean water. DNA: Scientists couldn't identify diseases. Antibiotics: Doctors couldn't treat infections properly.
