    14、, education and training.iv ISO/IEC 2015 All rights reserved ISO/IEC TR 18121:2015(E) Introduction New and emerging technologies are allowing learners to test and develop new knowledge for the creation of virtual experiments. By employing a collection of different technologies, virtual experiments a

    15、re widely used within K-12 and higher education institutions (e.g. scientific laboratory experiments, technical training in medicine and biomedicine) and also within corporate training (e.g. flight simulators, manufacturing process control). Virtual experiments allow access to a wide range of differ

    16、ent experiments, decrease the timeframe to complete experiments, eliminate hazardous situations, and reduce the costs of materials. To facilitate the development of virtual experiment technology and specification integration, this Technical Report defines a virtual experiment framework that indicate

    17、s how various standards and specifications can be combined to support the design, implementation, analysis and evaluation of virtual experiment systems. This Technical Report denotes the components and categories of related standards and specifications that can be used to support virtual experiment

    18、systems and learners. It illustrates how the components and categories can be structured to support implementations to improve reusability, reduce costs, and broaden applicability. It defines the framework of related virtual experiment standards and determines the mutual relations between different

    19、standards for designing, analysing and comparing different virtual experiment systems in order to promote the design and application of the virtual experimental components and systems. The framework of virtual experiment standards also helps to illustrate the categories of related virtual experiment

    20、 systems and their relations in order to guide the development of other standard-setting work and normatively describe virtual experiment system. Virtual experiments are typically accessed from an IT system, such as a learning management system (LMS), which provides the environment for learning. In

    21、addition to tools specifically tailored for learning, IT systems (such as LMSs) can also provide access to external tools. In a common scenario, an identity federation mechanism will automatically log into the external service but it is up to the learner whether to provide data inputs to the externa

    22、l tool. At the end of the activity, a score is returned to the IT system (e.g. LMS). This type of approach can be used to support activities, such as those involved in the scientific experimental approach, where there are requirements to repeat an experiment with a variety of parameters in order to

    23、assess their individual role in a process. There is a need to bridge the switch from the IT system (e.g. LMS) to an external virtual experiment tool, providing data inputs and recording outputs for further analysis. This Technical Report can be used to support these types of activities. In addition,

    24、 this Technical Report provides specific considerations for the development of ITLET supportive technology and specification integration. ISO/IEC 2015 All rights reserved v Information technology Learning, education and training Virtual experiment framework 1 Scope This Technical Report defines the

    25、framework for IT standards and specifications on virtual experiments supporting IT-enhanced learning, education and training. It is based on implementations of standards and specifications that are used to support virtual experiment, development, evaluation and management that rely on ITLET. This Te

    26、chnical Report provides a framework that can be used for virtual experiment systems that rely on ITLET, determines the categories of different virtual experiment standards and specifications and their relationships to facilitate their integration, promotes the appropriate design and application of v

    27、irtual experiment components so that IT systems that are being used are reusable, low cost, and more broadly applicable, indicates considerations to be taken into account when developing ITLET systems that are being developed or used to support virtual experiment systems, provides sample architectur

    28、e of a virtual experiment system framework that can be used to support further development of virtual experiments, illustrates various roles that different actors can have at various points within the virtual experiment system, demonstrates how standards and specifications that support virtual exper

    29、iments can be combined to form the basis for future work and implementations. The following aspects are not addressed in this Technical Report: specifications of the implementation details of virtual experiment systems; accessibility; privacy; security. 2 Conformance It is noted that it is possible

    30、for a virtual experimental instruction system to support more than one standard or specification by utilizing different combinations that include base standards, specifications, etc. The standards or specifications coordinate with circumstances or the virtual experiment instruction system that is co

    31、nfigured separately to support specific standard or specification combinations. This Technical Report provides the framework and objective to assist in the development of virtual experiments for information technology supporting learning, education, and training. This Technical Report also provides

    32、a proposed architecture of a system framework that is used to support the further development of virtual experiments. This Technical Report provides specific considerations for the development of ITLET supportive technology and for the integration of IT standards and specifications. TECHNICAL REPORT

    41、verview of virtual experiment framework The virtual experiment framework standard consists of the following four major parts. Basic framework standards and specifications Basic framework standards focus on various compatible specifications of the virtual experiment platform and tools. They are the b

    42、asis of the whole virtual experiment standard system. ISO/IEC 2015 All rights reserved 3 ISO/IEC TR 18121:2015(E) Application service standards and specifications Application service standards focus on the normative description of service interface provided by virtual experiment teaching systems whi

    43、ch can help to improve the management of services. Data processing standards and specifications Data processing standards are the hard core of the whole virtual experiment standard system, providing data elements of virtual experiment component metadata and a conceptual data mode, which are used to

    44、define an instance of metadata structure. Management and evaluation standards and specifications Management and evaluation standards concentrate on how to control and manage the virtual experiment procedures in a standardized way for the purpose of helping learner complete the experiment in the expe

    45、rimental processes. 5.1.2 Core feature of virtual experiment framework The virtual experiment framework mainly illustrates the categories of related virtual experiment standards and describes the relations among the standards in order to promote the virtual experiment resources-sharing and interoper

    46、ability of virtual experiment systems. 5.1.3 Basic specifications The virtual experiment framework is established on some related specification such as CP, CC, SCORM, etc. All the specifications are described in detail in their own documents. 5.1.4 Relationship The examples below provide the standar

    47、d structure of a typical virtual experiment instruction system which normatively describes the standardized environment of the virtual experiment instruction system. As shown in Figure 1, this virtual experiment instruction system conforms to some related virtual experiment standards which are divid

    48、ed into four categories: basic framework standards, application service standards, data processing standards, and management and evaluation standards. The specific explanations of virtual experiment instruction system are provided below. Basic framework standards and specifications The virtual exper

    49、iment instruction system may conform to the virtual experiment terminology specification to regulate the definition of key terms and the explanation of symbols which are used in the system. The system unify the terms in the development process and help users to translate and use the standard correctly; meanwhile, it may also be beneficial to manage the virtual experiments system. Basic framework standards are in reference to framework standards (ISO/IEC/TR 24725-1:2011),
