客观归一化测度

Question

我有一个关于清单中readNormalizedMeasure属性的问题。请参阅下面的SCORM 2004第三版清单。活动3从哪里读取其标准化度量？请给我解释一下。非常感谢。

Answer 1

活动3根本不读取任何跟踪数据。读取跟踪数据的唯一活动是活动1和活动8，它们从活动3的主要目标读取objectiveSatisfiedStatus。要测试清单并了解更多信息，请从http://www.naseelco.com下载LMS2004。它有一个测试模式，你可以在其中学习很多关于你的SCORM清单的信息。这是加载到LMS2004中的清单的快照，您可以在其中查看哪些活动读取/写入跟踪数据。
