Effect of Varied Types of Instructional Delivery Media and Messages for Engineering Education: an Experimental Study

摘要

In a Digital Signal Processing course, students received two different types of instructional delivery messages (online text only and text along with a simulation tool: MA TLAB) via two different types of instructional delivery media (desktop PC and personal digital assistant (PDA)). An experimental study was designed to investigate the potential main effects and the interaction of these two independent variables: instructional delivery message and instructional delivery media. Results showed that students expressed a significantly higher intention to learn in a desktop PC environment than in a PDA environment (F[1,21]=10.96, p < 0.05). We also found that students who used a MA TLAB simulation tool performed significantly better on an achievement test than those who did not use it (F[l,21 ]=10.96, p < 0.05).
