The Design and Implementation of Task-Based Learning Activities in 3D Virtual Environment

The educational application of 3D virtual environment can create a realistic learning situation to stimulate the learners' initial learning interest and motivation, bring them with a strong sense of immersive. However, because of paying too much attention to the interaction design and the verisimilitude of the learning contents, the instructors in 3D virtual environment often ignore the in-depth design of learning activities, as well as the further strengthening and sustaining on the learners' learning interest and motivation. In this paper, the task -- based learning method is introduced to 3D virtual environment as the core idea of learning activity design, and combined with the ARCS motivation model, the relevant theoretical designs are completed, including the task -- based learning activity model and the design principles and framework and the implementation process. Furthermore, a task-based learning activity system and another ordinary learning activity system are implemented in Open-Sim, to be used as the objects of the contrast group quasi-experimental study to validate the validity of the task-based learning activities in 3D virtual environment.
