Scorm 2004 第 4 版 CM-04b 测试

Question

我有一个关于 Scorm 2004 第 4 版 CM-04b 测试的问题。我不明白为什么在活动 15 中应该禁用上一个按钮。 Activity 15 的父级上有一个流设置为 true，因此按钮继续，并且应该启用上一个。有人可以向我解释为什么应该禁用它吗？

这是 Scorm 2004 第 4 版测试套件 - 测试 LMS 测试内容包 CM-04b 的清单。

Activity 15 是一个叶子，所以我们看它的父节点，它是树的根。根有 controlMode flow="true" 并且 controlChoice 未定义，因此我们采用默认值为 true。所以我不明白为什么应该禁用上一个按钮。

还有日志。

Answer 1

flow "true" 应该允许按照您的说明对请求进行排序。但是，如果选择为 false，则会在 LMS 级别隐藏导航按钮。

我在这里举了你的例子并对其进行了修改，以便我可以找出发生了什么。添加时...

<imsss:sequencing>
    <imsss:controlMode flow="true"/>
</imsss:sequencing>

...为了让您在每个部分中前进，您需要将其放在该活动的根目录中。这使下一个/上一个可以继续通过树中的活动。

我用 cmets 修改的 XML
