24、al Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields o
25、f technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint
26、 technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee
27、are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote.

It is intended to
42、 address mismatches between personal needs and preferences caused by any number of circumstances, including requirements related to client devices, environments, language proficiency or abilities. The terms and definitions within ISO/IEC 24751 are not judgmental but functional; the purpose is not to
43、 point out flaws in educational digital resources with respect to accessibility and adaptability, but to facilitate the discovery and use of the most appropriate content components for each user. In ISO/IEC 24751, it is recognized that learners experience a disability when there is a mismatch betwee
44、n the learners needs (or preferences) and the education or learning experience delivered. Disability is therefore not viewed as a personal trait but as a consequence of the relationship between a learner and a learning environment or resource delivery system. An individual who is blind is not disabl
45、ed when the lesson is delivered in audio, but an individual who does not have the necessary background knowledge to understand the lesson, or an individual who is listening to the lesson in a noisy environment, is disabled. Given this reframing, a learning environment is accessible when learner need
46、s can be addressed or matched (through adaptation, re-aggregation or substitution of digital learning resources). Accessibility is determined by the flexibility of the learning environment (with respect to presentation, control methods, structure, access mode, and learner supports, for example) and
47、the availability of adequate alternative-but-equivalent content and activities. The needs and preferences of a user may arise from the users context or environment, the technical requirements of the users device, the tools available (e.g. assistive technologies such as Braille devices, voice recogni
48、tion systems, alternative keyboards, etc.), the users background, or a disability in the traditional sense. Accessible systems adjust the user interface or configuration of the learning environment, locate needed resources and adjust the resources to match the characteristics of the resources to the needs and preferences of a user. This part of ISO/IEC 24751 provides a common framework for additional parts. These additional parts provide two complementary sets of information: a) the description of a learners accessibility needs and preferences, including 1) how digital resource
