15、 2016 All rights reserved ISO/IEC TR 20748-1:2016(E) Introduction The increasing amount of data being generated from learning environments provides new opportunities to support learning, education and training (LET) in a number of new ways through learning analytics. Learning analytics is a composit

16、e concept built around the use of diverse sub-technologies, workflows and practices and applied to a wide range of different purposes. For instance, learning analytics is being used to collect, explore and analyse diverse types and interrelationships of data, such as: learner interaction data relate

17、d to usage of digital resources; teaching and learning activity logs; learning outcomes and structured data about programmes; curriculum and associated competencies. Learning analytics is an emerging technology addressing a diverse group of stakeholders and covering a wide range of applications. Lea

18、rning analytics raises new interoperability challenges related to data sharing; privacy, trust and control of data; quality of service, etc. Through use case collection in the ad- hoc group on learning analytics interoperability, established under JTC1/SC36 in 2014, the following issues were identif

19、ied and captured as general requirements for learning analytics applications: For the learner: tracking learning activities and progression; tracking emotion, motivation and learning-readiness; early detection of learners personal needs and preferences; improved feedback from analysing activities an

20、d assessments; early detection of learner non-performance (mobilizing remediation); personalized learning path and/or resources (recommendation). For the teacher: tracking learners/group activities and progression; adaptive teacher response to observed learners needs and behaviour; early detection o

21、f learner disengagement (mobilizing relevant support actions); increasing the range of activities that can be used for assessing performance; visualization of learning outcomes and activities for individuals and groups; providing evidence to help teacher improve the design of the learning experience

22、 and resources. For the institution: tracking class/group activities and results; quality assurance monitoring; providing evidence to support the design of the learning environment; providing evidence to support improved retention strategies; support for course planning. In addition, learning analyt

23、ics practice can build upon prior work in LET standardization and innovation but there are several factors that require special attention. These factors include: requirements arising from the analytical process; data items required to drive operational LET systems are not always the same as desired

24、for learning analytics; ISO/IEC 2016 All rights reserved v ISO/IEC TR 20748-1:2016(E) volume, velocity and variety of the data collected for analytics indicate different IT architectures, which imply different interoperability requirements; use of learner data for analytics introduces a range of eth

25、ical and other socio-cultural issues beyond those which arise from exchanging data between operational systems. Therefore, this document gives a conceptual description of the behaviour of components related to learning analytics interoperability. In particular, this document specifies terms as well

26、as proposes a reference model for the learning analytics process and interoperability.vi ISO/IEC 2016 All rights reserved TECHNICAL REPORT ISO/IEC TR 20748-1:2016(E) Information technology for learning, education and training Learning analytics interoperability Part 1: Reference model 1 Scope This d

The reference model identifies relevant terminology, user requirements, workflow and a reference architecture for learning analytics. 2 Normative references The following do

The use cases illustrate key functionalities related to learning analytics by focusing on particular requirements that stakeholders

42、 may have and then outlining how such requirements can be reflected in workflows for learning analytics. A total of fifteen use cases were received in 2014. Use cases considered four main areas: learning analytics; assessments; ISO/IEC 2016 All rights reserved 3 ISO/IEC TR 20748-1:2016(E) data flow

43、and data exchange; accessibility preferences. The summary of the use cases is presented in Clause 5. The complete list of use cases is available in Annex A. 5.2 Learning analytics A stakeholder has previous experience with analytics dashboards available in online learning platforms (known as learnin

44、g management systems (LMS) or virtual learning environments (VLE). In general, data logs were not in a format that non-technical users could interpret, but these are now rendered (displayed) via a range of graphs, tables and other visualization forms, and custom reports designed for learners, educat

45、ors, administrators and data analysts. Learners may get basic analytics from dashboards such as progress relative to the cohort average marks or engagement ratio. Learning analytics are delivered with more advanced features, namely predictive analytics. Predictive analytics focuses on the pattern of

46、 learners static data (e.g. demographics; past attainment) and dynamic data (e.g. pattern of online logins; quantity of discussion posts). Once a students trajectory is drawn (e.g. “at risk”; “high achiever”; “social learner”), timely interventions can be planned (e.g. offering extra social and acad

47、emic support; presenting more challenging tasks). Learning analytics are used to enhance the personalized learning environment (PLE). Based on learning analytics output, the PLE can recommend learning pathways combined with learning content or resources. This service model enables fine-grained feedb

48、ack (e.g. which concepts have been grasped and at what level), and adaptive presentation of content (e.g. not showing material that depends on the mastery of concepts that the learner is yet to acquire). Other types of learning analytics are social network analytics and discourse analytics. Social n

49、etwork analysis makes visible the structures and dynamics of interpersonal networks to understand how people develop and maintain these relations (in the classroom or learning community). Discourse analytics requires the use of sophisticated technology to assess the quality of text in order to scaffold the higher-order thinking and writing skills that we seek to instil to learners. 5.3 Assessment One of the adv
