I have read @daisychristo's latest book 'Teachers vs Tech?' and it is simply brilliant - I cannot recommend it highly enough. Here are some of my takeaways in a thread...

Most huge investments in Ed tech have failed. If some of the biggest companies in the world with significant resources can't get this to work then maybe we need a serious rethink.

Although edtech has tended to promulgate some dodgy ideas, there are reasons to be optimistic about the possibilities of edtech to support the learning of information but not in replacing the teacher.

Using edtech to give greater control to students over their learning has generally failed. Could this be linked to ideas about cognitive load theory?

@daisychristo carefully describes why 'just Googling it' is doomed to fail and why we need to secure knowledge in long-term memory to be able to think more deeply and to understand what we might then read online.

This case study is equal parts hilarious and terrifying!

Why we should be cautious about using clip art and animations in instructional materials (with reference to the work of Mayer)

If memory is the residue of thought (as @DTWillingham suggests) then what will be remembered in some of the activities big edtech companies include in their curricula?

Is the future of edtech in helping students to remember key content through sophisticated quizzing algorithms?

On the risks of using 'flipped learning' strategies...

Devices can be hugely distracting even when they are not being used. Just having them near by can be enough to impact negatively on pupils' attention.

Honestly, just get a copy. It's ace.
