DRIP and the data poor

I have just read on the Matt Renwick's blog what DRIP stand for. Data Rich and Poor Information. But in his opinion, nowadays we, as teachers, have poor data about our learning process of our pupils. He says that we need modern information about that and perhaps today we are still using a oldfashion data in order to reach the correct information. It is an interesting article. He invites to participe into a chat about this quiestion. He says: "In tomorrow night’s All Things PLC Twitter chat (follow #atplc), we will pose questions to dig more deeply into what data means in the modern classroom. There are too many ways for learners to show what they know to ignore the potential of connected learning and continuous assessment. Join us at 8 P.M. CST for this discussion". It could be an interesting debate about new forms to understand the modern education system.
