Chronotype is our propensity to either wake up early or wake up late, to stay up late, or to go to sleep early.
You sometimes hear the terms “larks” and “owls.”
Some people are larks, they rise early, feel energetic in the morning, and then fade out by evening.
But people typically between the ages of about 14 and 24 are “owls.”
That is a period where, because of puberty, and changing bodies the hours of wakefulness shift forward a couple of hours.
So, people go to sleep later in the evening and wake up later in the morning.
Just like each learner has a unique learning style, different learners may learn better at different times of the day.
Research shows it is important for the learner to think about when they are most alert and plan their learning to suit.
Different qualities of memories and alertness seem to be better at different times of the day for different people.
Our adult learners are typically outside the between 14 and 24 “owl” age bracket and research shows learning doesn't appear to be less effective in the afternoons, so our courses are 8.30 am to 1 pm when learners are more alert and better at learning.
