摘要: Constructing models of dynamic systems is an important skill in both mathematics and science instruction. However, it has proved difficult to teach. Dragoon intelligent tutoring system intended quickly effectively teach this skill. This paper describes evaluation it. The randomly assigned students a university class either or baseline instruction that used as editor only. Among who did use their systems, the tutored scored reliably higher (p < .021, d = 1.06) on post-test than only conventional editor-based
