Immersive virtual reality for learning about ecosystems: effect of two signaling levels and feedback on action decisions.

Introduction: The goal of the present study was to test the effect of signaling associated with feed-back in learning forest ecosystems in the context of realistic living forest simulator, in IVR conditions for students in agriculture. Two signaling modalities, corresponding to two signaling levels, were investigated: visual of forest elements (tree species, plants, flowers, fungi, wet-areas etc.) and , both with text in pop-up windows, in a 2x2 experimental plan.
