National bodies that are members of ISO or IEC participate in the d

14、evelopment of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-gover

15、nmental, 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 technical committee, ISO/IEC JTC 1. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC

16、Directives, Part 1. In particular the different approval criteria needed for the different types of document should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility that so

21、borative learning communication: Part 1: Text-based communicationiv ISO/IEC 2015 All rights reservedBS ISO/IEC 19780-1:2015ISO/IEC 19780-1:2015(E) Introduction Collaborative communication in general Collaborative learning that is supported with information and communication technologies (ICTs) can i

22、nvolve the use of a range of media, including audio (e.g. IP telephony), video (e.g. video over IP), graphics (e.g. shared whiteboard) and text (e.g. chat, computer conferencing). Combinations of these media (e.g. audio telegraphics) can also be used in collaborative learning activities. ISO/IEC 197

23、80 focuses on messages and events arising in the course of collaborative learning activities, using a range of collaborative tools and media types. ISO/IEC 19780 understands and defines these communicative actions and events as being sent and received by participants and within environments, as thes

24、e are conceptualized and defined in ISO/IEC 19778. This part of ISO/IEC 19780 focuses on text-based communications and messages. Future editions or parts of ISO/IEC 19780 may address communications using other media (e.g. audio or video), or communications independent of any particular medium. Exper

25、ience and feedback deriving from this part of ISO/IEC 19780 and from work with evolving communication media are likely to play an important role in determining the shape and direction of this future standardization work. In this context, “text” can be defined in terms provided by the Oxford English

26、Dictionary: “the wording of anything expressed; the structure formed by the words in their order; the very words, phrases, and sentences as written.” Text is further understood here as that which can be expressed using a specified character set (here the “coded character sets” defined in ISO 10646).

27、 The use of markup languages derived from the specified character set used is also admissible. Some of the most common forms of ICT-supported collaborative learning involve the exchange of messages or text-based expressions. As defined here, text-based collaboration and communication is characterize

28、d by relatively brief messages or “small” expression bodies (e.g. a single word to a few paragraphs), and by relatively short time intervals between such expressions (fractions of a second to days). The result is that content generated through this type of communication tends to be highly context-de

29、pendent, with any one textual expression often gaining its meaning from complex relationships to others. This makes the portability and potential reconstruction of these relationships and of this context of great significance. Within the general parameters described above, the length of and time int

30、ervals between discrete communicative actions or messages can vary. Collaborative technologies and activities with the smallest intervals between messages are often labelled “synchronous”, and tend to be associated with the term “chat”. Those with longer intervals and more sizeable expression bodies

31、 are often labelled “asynchronous”, and tend to be associated with terms such as “discussion” or “conferencing”. In the terminology defined in ISO/IEC 19778, both synchronous (chat) and asynchronous (discussion) represent particular collaborative services, composed of collaborative tools (ICQ, Windo

32、ws Messenger, etc.), which provide collaborative functions (e.g. instant messaging). These functions, in turn, contribute to particular collaborative effects (e.g. facilitating the gradual achievement of consensus). NOTE Italicized terms in the paragraphs above and throughout this part of ISO/IEC 19

33、780 are defined in Clause 3 or in ISO/IEC 19778-1. Text-based communication in particular This part of ISO/IEC 19780 presents a Data Model for text-based expressions. A collaborative workplace is defined as an instantiated independent entity, consisting of the collaborative activities of a collabora

34、tive group, which works together by means of a collaborative environment (ISO/IEC 19778-1 to ISO/IEC 19778-3). As these definitions indicate, collaborative workplaces are associated with two major kinds of components: collaborative service components; collaborative group components. ISO/IEC 2015 All

35、 rights reserved vBS ISO/IEC 19780-1:2015ISO/IEC 19780-1:2015(E) This part of ISO/IEC 19780 provides a Data Model to accommodate the data constituted by and associated with text-based messages or expressions, which are exchanged among collaborative group members within a collaborative environment. E

36、xpressions are composed by and exchanged among collaborative group members within a collaborative workplace. Collaborative environment components (collaborative services, tools and functions) facilitate these collaborative activities, resulting in various collaborative effects. Typical effects can i

37、nclude, for example, “reaching a compromise on a controversial issue”, “exploring arguments for and against a particular decision item” or “getting to know students in a class”. The classification and definition of particular collaborative effects is outside of the scope of this part of ISO/IEC 1978

38、0. Expression Data Model instantiations are associated by reference to collaborative group Data Model and collaborative environment Data Model instantiations. This can be illustrated through the example of a mailing list considered as a collaborative workplace. Such a collaborative workplace is inst

39、antiated as an independent entity by associating a particular list of email addresses (each address being associated with a participant) with a particular email service (or with specific aspects of such a service). Collaborative group members (being identified in the system by their email addresses)

40、 interact with each other and with the email service by composing, sending, receiving, reading and responding to email messages or expressions. The email service accepts emails from collaborative group members only, and forwards or reflects them to all other collaborative group members as specified

41、in the email address list of the collaborative group. Naturally, such a collaborative context, as an abstract entity, does not encompass the holders of the email addresses nor the email server, the email clients or the computers of the participants. Expressions are composed, sent and received by mem

42、bers of the collaborative group. These collaborative activities are made possible through the email service provided through the collaborative environment.vi ISO/IEC 2015 All rights reservedBS ISO/IEC 19780-1:2015INTERNATIONAL ST ANDARD ISO/IEC 19780-1:2015(E) Information technology Learning, educat
