      This article doesn't mention rote. Do you believe that rote is the only or best way to develop long term memory?

      sigh...one only obtains long term memory thru repeated practice. Also known as "rote".pic.twitter.com/sua4YtETmD

      Why, then, do students who "successfully" engaged in repeated practice of the division of fractions not retain their skill in this activity? Why do so many college graduates not recall how to divide 11/31 by -53/97?

      because they haven't MASTERED this basic math skill. Use of calculators and other manipulatives have inhibited their ability to do so. Simply "knowing" isn't good enuf. Without mastery long term memory cannot occur http://www.psy.cmu.edu/~siegler/Siegler-etal-inpressPsySci.pdf ….

      @TaraMathBC: See Bahrick & Hall (1991) J. Exp. Psych.: General, 120, pp. 20-33. Learners of algebra whose practice persisted only while it was imposed on them did not retain much. If practice is miserable, no one will persist in it once the obligation to persist is removed.

      well that can be said for ANYTHING. That's what happens when kids haven't mastered basic math facts, like fractional arithmetic, so they can learn Algebra effectively. Try and rush students thru procedures w/o mastery, leads to disaster. Just saw thishttps://twitter.com/clairlemon/status/1030307817297563648 …

      Tara Houle added,

      Claire LehmannVerified account @clairlemon
      Because a) you want to store facts in your long term memory & retrieve them when relevant b) your working memory gets overloaded easily c) it's hard to be critical w/out having mastery & d) it's hard to be creative unless you have knowledge across domains https://twitter.com/Mexikansk/status/1030302461876219906 …

      Ms Houle, you seem determined to ignore a basic point: you can't get kids to practice enough to achieve useful, durable results simply by compelling them to practice. This has been tried and tried and tried, and the main effect of the effort has been to inculcate math hatred.

      4. what has occurred over a 30 yr period is an obsession with child centred, inquiry based learning to the detriment of successful classroom instruction. When we know what works, and how to employ it, why do so many choose to ignore it?

      Ms Houle, I am a mathematician. I love mathematics. Its propagation to the next generation is an urgent concern of mine, to which I have given much of my life. I respectfully point out that Euler's ALGEBRA of 1770 remains arguably the best text ever written on this subject.

      well @rastokke is a mathematician who authored https://www.cdhowe.org/sites/default/files/attachments/research_papers/mixed/commentary_427.pdf … and @rcraigen also joined her to start http://www.wisemath.org  to raise awareness over declining math performance. Anna's report is pretty conclusive about what the prob's are.

      For reference, you might look at this. But the literature is extensive, and you should by no means stop here. http://bit.ly/2vRKY6b

          Culture surrounding education is much different in Japan than it is here. That is not new nor surprising. I fail to see how that adds to the discussion here.

          I regret, Ms Houle, that I have little hope of persuading you that this subject includes any questions to which you do not already possess all the answers. Good luck with your efforts. But I urge you to reassess them in twenty-five years.
