我正在研究可汗学院的exercise framework,更具体地说是单词问题。
在进行单词问题练习时,学生经常会遇到相同的单词问题,只会更改数字和名称。这并不理想,因为学生可以快速学习模式并提取相关数据而无需阅读整个问题。
有没有办法在不改变单词问题含义的情况下改变句子结构?关于如何解决这个重复问题的任何其他想法也受到欢迎。

创建单词问题时,请使用某种语法来表示各种等效短语,有时会在文章旋转中进行。然后在显示单词问题时,在它们之间随机选择。
语法示例:
[Name] {goes to the store and /goes to the market and /}{purchases/buys} [number] {apples/pears/bananas}. He {gives/sells/donates} [number] to [name]. {How many does he have now?/How many does he have left?/How many does he still have?}
上面的语法可以创建的2个示例单词问题:
Bob buys 8 bananas. He sells 5 to Alice. How many does he have left?
Harry goes to the market and purchases 19 pears. He gives 2 to Alex. How many does he have now?
对于更多组合,您可以使其递归。
