I love this exercise. First aid training requires hands-on instruction and practice, and my problem in this course was to try to include some simulations to aid in the instruction and prepare learners for the practical application in subsequent face-to-face coursework. So the dragging and dropping are meant to represent physical actions a person would perform in real life, but the focus is on the thought processes behind the actions. Each learner action - right or wrong, in order or not - results in instructive feedback to guide their thought processes. Wish you could try it out, but it was built in Flash, which can no longer be shown in a web browser. So I made a video of the exercise in action to show how the learner could drag items in the wrong order, or to the wrong place. (Never tie directly over the wound!)
