Understanding the difference between classroom learning and online learning on Medical Imaging with computer lab exercises

Abstract

In this paper we present a study on the effectiveness of using a computer simulation software, SimuRad, in an undergraduate Medical Imaging course. This course is offered regularly in two different modes, i.e. an on-campus section in every Fall semester and an on-line section in every Spring semester. This enables us to compare students' learning experience with the same software in different environment. In this study, we focus on statistical analysis of three derived factors from our assessment results, i.e. performance improvement, difficulty level and usability satisfaction. We intend to identify the statistical relationships among these factors under classroom learning and online learning modes. Through this study, we are able to verify some hypotheses we introduced in our previous works. In particular, we will show that there can be no significant deficiency for online students to understand course content with the help of the computer lab exercises, and in certain scenarios, computer labs are more helpful to online students.
