如何计算SCORM内容的进度? [英] How to Calculate Progress of SCORM content?

问题描述

我试图获得一个分数，并从SCORM内容(2004版)中取得进步.到目前为止，我已经能够使用自定义的书面LMS API将CMI值保存到我的数据库中.

I'm trying to get a score, and progress from SCORM content (2004 Edition).So far I was able to save CMI values to my database using custom written LMS API.

cmi.score.raw--->>0 
cmi.score.max--->>15 
cmi.score.min--->>0 
cmi.score.scaled--->>0 

我需要知道如何根据上述值来计算学生的进度，分数和等级. 有没有特定的方法或功能可用于计算钙盐?还是我错过了SCORM的一些价值?

I need to know how to calculate the progress of the student, score and grade from above values. Is there a any specific way or function for calaluclate progress? Or am I missing some value from SCORM?

推荐答案

通常，您不会计算得分，这是您显示的值-raw和scaled，由SCO设置.为了取得进步，2004年包括了cmi.progress_measure值，尽管我认为它只是偶尔使用，并且会再次由内容设置.直接在SCORM中并没有真正的等级"概念.有精通分数(或按比例划分的及格分数)，旨在反映SCO被认为合格所需要的分数.参见 https://support.scorm.com/hc/en-us/articles/206166246-Setting-the-mastery-score 和

Generally you would not calculate the score, that is the value that you've shown--raw and scaled, and is set by the SCO. For progress, 2004 includes the cmi.progress_measure value though I think it is only used sporadically and again would be set by the content. There isn't really the concept of a "grade" in SCORM directly. There is the mastery score (or scaled passing score) that is intended to reflect the score required for the SCO to be considered passed. See https://support.scorm.com/hc/en-us/articles/206166246-Setting-the-mastery-score and https://support.scorm.com/hc/en-us/articles/206167026-What-are-the-elements-for-placing-a-passing-score-in-your-SCORM-manifest- for more about this value.
