Another important area of the English AR classroom
shown in Fig. 6 is the operational area. Assignment and the
assessment are always the key phases of the learning cycle.
The assignment in AR classroom can be designed as step-bystep
experiment or the observation of the real objects. The
assessment could be also carried out in the same manner.
Using of AR objects makes the assignment and assessment
more interesting and precise. The learning process not only
could be recorded but also repeat the flow experience.

Last but not least, the AR classroom implements an agent
area shown in Fig. 7 to augment 3-D avatar in the learning
scene. In the real learning environment, the virtual agent can
be seen and interact with. This mixed reality provides a novel
and interesting way of learning.
