是的，我们需要看当前的模型是否可以修补，但我们也需要研究新途径看是否有更好的方法。

Yes, we need to see if the present model can be fixed, but we also need to investigate new avenues to see if there's a better way.

人们认为，可能确实有一个真实存在的减速度没有为当前的模型所考虑到，原因如下。

It has been viewed as possible that a real deceleration is not accounted for in the current model for several reasons.

当前的模型大多都只是在空间的某些特定方向上求解，在实际应用中有一定的局限性。

Most of the models we have were focus on some specific directions, which was confined when applied.

So for each student the tutor builds a model of that Student's current state what the computer thinks they Know and doesn't know, and tries to present the student options that best meet what the tutor thinks are the student's need at that moment.

因此辅导系统会给每个学生,创建一个模型记录他们当前的学习状态,判断他们已经掌握和还不了解的知识,然后给出此时导师认为,最符合他们需要的选择。
