The purpose of this standard is to ease the design, implementation and use of online laboratories for education. It is understood that laboratory activities are required in Engineering, Science, and Technology Education. Laboratory activities aim at fulfillling pedagogical objectives and developing experimental skills. Laboratory activities can nowadays rely on digital education solutions. Such solutions generally integrate networked electronic devices such as computers (desktops, laptops, tablets, and smartphones) as well as networked measuring instruments or electromechanical devices. Online laboratories for education are technology enhanced learning resources. They are becoming more and more popular. This standard defines and establishes the relationship between all the components required to carry out pedagogically sound experiments using laboratories (equipment, software, hardware, and services). The standard aims at facilitating the work of lab owners when setting up and sharing online laboratories; the work of platform managers when offering and enabling the exploiting of online laboratories as learning objects; the work of teachers when integrating and implementing an online laboratory in their pedagogical scenarios; and the work of learners when interacting and learning with online laboratories.
