@RuthTrundley @SmartJacques I remembered this paper which *might* be tangentially related to your enquiry https://t.co/mTHsBCjmDB It takes a CLT perspective on 3 conditions of images (1) children dragging in dynamic geometry (2) children watching teache…

@mathstechnology @SparksMaths https://t.co/GK4zHtCRrW seems to indicate that just observing a teacher manipulating might cause extraneous CL rather than manipulating themselves. Finger movements seem to help. Who knows whether dragging a slider or draggin…
