Earlier this week, Thomas More organized a conference in Antwerp on knowledge-rich curricula. I could not attend myself, but I was lucky enough to have a second chance to get several along yesterday in Rotterdam.
Tim Surma used a word I would like to spotlight today: knowledge poverty.
Perhaps this quote from E.D. Hirsch is an excellent introduction to make this word clear:

In The Ingredients for Great Teaching, I explained the importance of knowledge and how poor background knowledge can create and increase inequality. Still, I think this concept makes it even more apparent. A child can be smart enough, but by hearing less school language and other vocabulary – think of the 30 million word gap, for example – start with a deficit that is difficult to catch up with without a targeted approach. Read more about features of knowledge-rich curricula here or soon in this new book by a.o.  Tim Surma, John Hattie, Dylan Wiliam, Nick Gibbs,  and many more.
