This paper describes a web-based virtual laboratory that improves the automatic control teaching of undergraduate courses. This is achieved by optimizing the time the students spend in the real laboratory. The virtual world or three-dimensional scenes of real laboratory plants gives the students the opportunity to ''learning by doing'' through web-based systems at the location they want, and at the time they like. This virtual laboratory gives the students the tools to be more prepared and therefore, use the time more efficiently and effectively when working in the real laboratory plant. The student does not require the installation of special software on his remote computer; only need a common VRML enabled browser. An example of a developed virtual laboratory of interconnected tanks is presented.
This paper shows remote experimentation using mobile technology for didactic purposes. Students using WiFienabled mobile devices, such as smartphones, tablets or PDAs can interact with physical laboratory hardware. Through a mobile device interface, in real time the user can verify what's happening on laboratory hardware when they change the system parameters. Additionally, the application provides the students a tool for taking advantage of their spare time at the University. Students can perform the lab practices even when the lab facilities are closed. All user activities are stored in a database for later analysis carry out by the professor. Also, students can store their experiments when is finished in order to make an off-line result analysis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
