Abstract

We present an evaluation of various kinds of feedback in SQL-Tutor. Our initial hypothesis was that low-level feedback, containing all the details of a correct solution would be contra-productive, and that high-level feedback referring to the general principles of the domain that the student's solution violates would be highly effective. The evaluation study performed in 1999 confirmed our hypothesis.

评价SQL-Tutor中反馈的有效性

我们对SQL-Tutor中的各种反馈进行了评估。我们最初的假设是，包含正确解决方案的所有细节的低层次反馈将会产生相反的效果，而涉及学生的解决方案所违反的领域的一般原则的高层次反馈将是非常有效的。1999年进行的评估研究证实了我们的假设。
