A web-based interactive intelligent tutoring system for undergraduate engineering dynamics
Ning Fang, Yongqing Guo · 2013
A Web-based interactive intelligent tutoring system was developed and assessed in an engineering dynamics course. The system consists of two learning modules to help students learn how to apply the Principle of Work and Energy to solve particle and rigid-body dynamics problems. Student learning gains were compared using a quasi-experimental research design that involved pretests and posttests in both a control semester (n = 62) and a treatment semester (n = 44). It is shown that the ITS modules increased student learning gains by 37-43%.
