-- 高手请指教，在此谢过了！
我是新手，对scorm了解的不深刻，所有一些地方不明白
scorm sequencing and navigation部分中，序列中定义了三个数据模型，其中一个是跟踪模型，里面记录了三方面的内容。
我想知道的是，这些信息数据是所谓的cmi数据吗？
如果再e-learning的设计过程中，我想通过这些信息来介入学习的过程，是可以的吗？
请大虾多多指教！
谢谢了！顺祝春节愉快！！

-- 作者：echo6459 -- 发布时间：2/2/2006 1:26:00 PM -- 在scorm 论坛上 有人对这个问题给了我这样的回答 The data model is called "cmi" for historical reasons. It is based on the data model originally defined in the AICC specification in which CMI stood for computer managed instruction. The data model was later was taken up by an IEEE working group going by the moniker "CMI" and was the base for the IEEE 1484.11.1 standard of which the SCORM 2004 "cmi" data model is an application. As to whether the data can be used to modify the user experience, definitely so. How a SCO uses the data for its own experience adaptations is outside the scope of the SCORM. But in SCORM 2004, some of the data collected in the CMI data model can influence the application of adaptive sequencing rules defined in the activity tree (activities within activities) that is specified in a SCORM package manifest. |

-- 作者：echo6459 -- 发布时间：2/5/2006 8:06:00 PM -- There is a lot of overlap between the data model in the RTE book (which basically describes the way learning objects are launched and communicate with the runtime environment) and the data models defined in the SN book (which basically describes how to add sequencing behavior by defining the content organization in a package as an activity tree and specifying rules that will govern the sequencing and management of the activities by a RTE). The data models were defined by different groups from different cultures, and therefore the naming conventions for similar or identical data elements don't always match (e.g. "measure of satisfaction" is what many people call, in short, a "score", but is it better to use a verbose term or a short term in formal notations and encodings?). To complicate things a little more, there are some cultural differences in data modeling conventions, e.g. the use of flags in the SN data model. An upcoming update of the SCORM 2004 documents is expected to contain a section summarizing the mappings between the data models. |
