At home, parents were more likely to read with their children than to practice math.
在家里,父母更有可能和孩子一起阅读,而不是练习数学。
The result: students' math skills declined around the nation.
结果是:全国学生的数学能力都有所下降。
And students are not recovering as quickly as educators hoped.
学生并没有像教育工作者希望的那样迅速恢复。
Educators worry about how they will perform in high school and whether science, technology and medical fields will be available to them.

Adding to the difficulty of catching kids up is the debate over how math should be taught.
关于应该如何教授数学的争论增加了帮助孩子追赶学习进度的难度。
Some say schools should center procedural learning, like teaching kids to memorize how to solve problems step-by-step.
一些人表示,学校应该以程序性学习为中心,比如教孩子们记住如何一步一步地解决问题。
Others prefer conceptual understanding, in which students learn underlying math relationships.
