Students can select the learning method according to their
preference. In the part of controllable 3D models, students can
manipulate the 3D models to see any viewpoint. In addition, we
also integrate the instruction with 3D models. Students can
manipulate the 3D models freely and the instructions will be
displayed when students move the mouse to the sensing area,
see “Fig. 12”. This method provided more interaction with
students. In the part of 3D animations, we let the 3D models
rotate automatically. The instruction displayed beside the 3D
models. There were some different classifications of instruction
that students can learn easily. In the part of 2D illustrations, we
used the 2D illustrations to assist learning and displayed the
Figure 11. Three kinds of presentations.same instruction with 3D animations. In addition, the
instructional contents provided the whole knowledge that may
be used as a question in the Q&A function. If students don’t
know the answer in the Q&A function, they can go back to
learn the knowledge that they lack.
