We can divide the physical experiments into three fundamental groups.
The first group consists of real experiments conducted in the traditional ("face to face") school laboratories. Working in the classical school laboratories provides a direct contact with real measure equipment and offers an immediate feedback of the teacher or the classmates.
The second category of physical experiment comprises virtual experiments conducted in virtual laboratories. Students do not work with real laboratory tools in these laboratories, they only control virtual objects.
The third group represents the real experiments that can be on-line controlled by users via the Internet. A remotely controlled experiment or in short a remote experiment is used as a nomenclature for these kinds of experiments.
Remotely controlled experiments have several benefits different from simulations in virtual laboratories and from classical experiments in the traditional school laboratories:
