I hope the textbook will provide a foothold for students of the subject.

我希望材能让专业的生打下基。

Isn't this textbook beginning to date?

材不是已渐渐陈旧了吗？

In other words, get the students to use what they have to learn to think, they will unheedingly learn and remember.This is more effective than rote-learning.

换句话说，让生多多运用材进行考，让他们在不知不觉中把材记住，而不是一味要生强记死，效果更能提高。
