Advantages and Disadvantages

Virtual field trips/tours should not altogether replace actual field trips. The real experience is sometimes necessary and are absent from virtual field trips (VFTs). However, the advantages of VFTs are extraordinary.
Virtual field trips can be made available for all levels of users and be individualized to meet the needs of individual students. They offer rich learning experiences and are wonderful learning and teaching tools. For students who are better hands on learners, the opportunity to manipulate a computer and experiment with images and change viewpoints will keep a student better engaged. VFTs also offer convenient flexible access. Lastly, for students who are going on an actual field trip, virtual tours can enhance or build upon what a child is about to experience or has just experienced. And for the student who won't have any other opportunity, what better way to bring the experience to them.
The disadvantages, in my opinion, are few, but worth mentioning. Limited knowledge of the computer and limited navigational skills may hinder an individual and perhaps even intimidate them. Lacking sensory experience with the exhibits is another disadvantage. Virtual tours cannot typically offer touch, smell, and aural feelings.
From a teachers perspective, disadvantages would include lack of permanent sites, too many sites that aren't worthy or high quality, and the difficulty finding appropriate sites.
