The Wing to Heaven

Who is Herbert Simon?

Herbert Simon was one of the great scholars of the twentieth century, whose discoveries and inventions ranged from political science (where he began his career) to economics (in which he won a Nobel Prize) to computer science (in which he was a pioneer) and to psychology.

Simon was one of the towering intellectual figures of the twentieth century.

In this vision, the teacher is a guide-at-the-side who is there to ensure that students have the right resources and don’t go off track. This approach is generally described as ‘inquiry learning’.

It doesn’t work

Unfortunately, the evidence to support inquiry learning is underwhelming. Approaches that have low levels of teacher guidance have repeatedly failed. Those where the amount of guidance is increased have more supporting evidence but, even then, under the favourable…
