Dear @OECDEduSkills - Please stop with the 21st century skills nonsense! You - including or maybe especially @SchleicherOECD - have done enough damage. Spend your time and our money studying things that actually exist and that can make a difference. oecd.org/en/publications/oec…

Three things that seem to be contributing to poor math achievement: 1. Multiple strategies for novice learners. Recommendation: Choose an efficient strategy that generalizes easily to (e.g.) larger numbers, teach it well, give lots of practice on it. 2. Too much focus on manipulatives & pictures. Recommendation: Fluency with abstract symbols sets kids up for later success. Move quickly to the abstract - that's where the majority of practice should be. 3. Not enough practice. Recommendation: Give lots of practice and then give more. It's how we get good at math.

If students struggle with fraction arithmetic, algebra is inaccessible. If they struggle with basic number operations (including times tables), fractions are inaccessible. Math is hierarchical & gaps compound. There's no way around it. We have to get math right in primary.

Love this. We believe the same at @Smartick: short, optimized learning sessions can be incredibly powerful. Not every child will attend an Alpha School, but technology can bring high-quality learning to millions.

My new book about VAR is out on 7 Nov. It's about football. It's also about authority, rationality & technology in the 21st century. You can pre-order now. amzn.eu/d/eCJHKYJ I'm also giving away a free copy. Retweet this post and I'll pick a winner on Fri 25 Oct.

📝 Frequent Practice Tests: Giving frequent, low-stakes practice tests can boost long-term retention and help reduce stress, which often impairs memory performance. These can even be ungraded—a pop quiz at the start of a lesson or a trivia quiz on Kahoot, for example. 9/12

🗓️ The Spacing Effect: Instead of covering a topic, then moving on, revisit key ideas throughout the year. Research shows students perform better academically when given multiple, spaced opportunities to review learned material. 8/12

Summer learning loss is real. If your child is not doing kumon, he is missing out on developing self learning and mastery skills!!
