我对清单中的 readNormalizedMeasure 属性有疑问。请参阅以下 SCORM 2004 第 3 版清单。Activity 3 从哪里读取其标准化度量？请为我解释。非常感谢。

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。要测试您的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，您可以在其中了解很多关于 SCORM 清单的信息。这是加载到 LMS2004 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。
