It was the fifth grade, I was a model student.

那时我五年级，我是模范学生。

The teacher told me that my son is such a model student.

老师跟我说我儿子是一个很棒的模范生。

And I promised the dean I'd be a model student.

我答应系主任要做个模范学生。

She had to tell them that I was a model student, and that I'd never, ever use it for anything except my studies....

我是模范学生，而且我将永远不把它用于学习以外的事.

These four probabilities are used in a set of equations that update the student model, keeping a running assessment for each skill the student is supposed to know.

这四个概率用于一组更新学生模型的方程式，对学生应该知道的每项技能进行持续评估。

For that, intelligent tutoring systems build and maintain a student model – one that tracks, among other things, what production rules a student has mastered, and where they still need practice.

为此，智能辅导系统建立并维护一个学生模型——一个跟踪学生掌握了哪些生产规则，以及他们还需要练习的地方。

After we compute the right value, we plug it into our first equation, updating the probability that a student has learned a particular skill, which then gets stored in their student model.

在我们计算出正确的值之后，我们将它代入我们的第一个方程，更新学生学习特定技能的概率，然后将其存储在他们的学生模型中。
