Why mix different kinds of maths questions after a skill has been learned?
Blocked practice makes the required method obvious because every nearby question is the same type. Mixed practice can force the learner to notice the structure of the problem and select a strategy.[1]
Toku 如何運用這個原理
As Toku grows beyond initial skill practice, mixed review can bring previously learned families back together so your child must recognise what each question is asking for.
研究發現
Mathematics experiments have found benefits when practice problems are spaced or shuffled rather than kept in a conventional blocked order.[1]
A classroom study with seventh-grade mathematics found better delayed performance after interleaved practice than blocked practice.[2]
為什麼這對您的孩子有幫助
Your child can practise choosing the method as well as carrying it out, which is closer to the demand of a mixed paper or unfamiliar problem set.
First learn the tool. Later, practise recognising when that tool is the right one.
