Report about a great lesson

I just had such a great lesson yesterday, I am writing it up here so I can remember it. Maybe some other teachers will find it useful, too.

Teaching points were:  pronunciation of /ae/, language of machines, passive voice in present simple tense for describing processes
Level: pre-intermediate

Students are two middle aged colleagues at a company that produces oil. One is a lab tech, the other is in finance/administration

• Warmer. I made 3 columns on board titled nouns/ verbs/ adj and asked Ss to write appropriate words containing the ae sound in the columns. I had one example for each column already in.
• Pulled up lots of language, eg seasons, months, days 
• S at board, T out of limelight
• They had to talk
• Oil refining
• Elicit steps of refining vegetable oils, T put up
• Makes Ss experts, it's their field, speak confidently because know it
• I got important details about their jobs, expertise eg office worker S knows oil
• Create first step in passive sentence, The rapeseed is pressed.
• Show/elicit form
• Explain use, present simple passive to describe a process
• Ss created further steps of oil refining T helped make passive sentences
• Telephone listening - fresh topic, turn away from efforts with passive
• Listen 2 times, let them panic, get 1-2 words
• Read and listen
• Read out loud to each other
• Listen one more time
• Close, next lesson repeat/revise/practice passive and telephone

• "Repetition is the mother of all learning"
