The authors seem to propose a paper which focuses on the use of virtual technology in science learning. However, it is unclear what the contribution of their theoretical exploration is.  This a very well known and researched theme which has been covered in journals such as Presence by a variety of researchers: technologist, psychologists, etc.  It is therefore unclear what the main contribution is and what methodology has been used

This paper has both content and methodological problems.
Content wise reference should have been made to previous research and explain the interest of revisiting this area.
Methodology is not clear and it seems this is just a theoretical essay which has not got good grounding.  A practically based research methodology would have been more valuable.
