According to Barad in the above quote, meaning is an ongoing performance in a play or dance of different agentic bodies/matter, trying to make themselves intelligible to one another. What kinds of meanings we make matters. This means that our instruments, tools or apparatuses for meaning-making matter, not least in relation to how we think that children learn. Consequently we need to ask ourselves what kind of knowledge we produce with the tools or ‘apparatuses’ we use in our learning activities with children and students.
