Learning with just enough help

The idea in one sentence: there are things people can do alone, things they can’t do yet even with help, and a middle band they can do with the right support. That middle band is where your teaching does the most good.

You’ve seen this already

Think about a child learning to ride a bike. Riding round the park alone? Not yet. Doing nothing but watching other children ride? Not much use either. What works is the parent running alongside, holding the back of the saddle. The child is really riding, just with help.

Then, bit by bit, the parent’s hand gets lighter. One day they let go and the child doesn’t notice. The help was there exactly as long as it was needed, then it was taken away.

Why it matters for your teaching

Say you’re showing a new healthcare assistant how to take a blood glucose reading. Here’s how the same skill looks at three different pitches:

	Too easy	Just right	Too far
What happens	They watch you do it for the sixth time	They do it on a real patient while you stand beside them and prompt	They do it alone on their first day, on a patient who is anxious and hard to communicate with
What they learn	Not much new	The skill, with a safety net	Mostly worry, or a way to look as if they know

The middle column starts from what they need to do: take the reading safely, on their own, soon. Then it gives them just enough help to do it now, and plans to take that help away.

That plan for taking help away is often called scaffolding. Teaching That Lands names it briefly in Session 1: one idea at a time, shown when people are ready, with support taken away as they gain confidence. Participants have just been through it themselves, in two slide redesign rounds with less help each time.

Try this

• Find out what they can already do. Before you start, ask, or watch them try. You can’t pitch to the middle band if you don’t know where it is.
• Do it with them before they do it alone. Show it, then let them do it with you prompting, then let them do it while you watch. Each step has a bit less of you in it.
• Plan when the help comes off. Decide in advance which prompts you’ll drop next time. Help that never comes off isn’t scaffolding any more.
• Use the colleague who learned it recently. Someone who learned it last month may remember what was hard better than someone who learned it years ago. Pair them up, and stay nearby.

How sure are we?

The zone of proximal development is an influential idea, not a tested finding. It comes from work on how children develop, and it appears in only a few of Vygotsky’s writings. Using it for adults at work is a sensible extension, but nobody has tested it as such.

The firmer evidence is on scaffolding, from later studies of tutoring and classroom teaching, mostly with children and students. Reviews suggest that learning by solving problems works better when it comes with good structure and support (Hmelo-Silver et al., 2007). How well this carries over to busy healthcare workplaces has not been well tested.

Two common mix-ups. “Scaffolding” isn’t Vygotsky’s word: it came from other researchers, later. And the zone isn’t the same as the “comfort zone, stretch zone, panic zone” picture used in coaching, which is a different idea.

Where it comes from

Lev Vygotsky was a Soviet psychologist who died in 1934. His writing was little known in the West until it was translated, and a collection called Mind in Society (1978) made the idea widely known. The word “scaffolding” came from David Wood, Jerome Bruner and Gail Ross in 1976, in a study of a tutor helping young children with a block-building puzzle.
