3.14. Completion Threshold
The completion status of an activity may be explicity used (Completed / Incomplete) or a partial measure of progress may be evaluated against a defined threshold. The Completion Threshold for an activity may be described using the elements shown in Table 3.14a.
Table 3.14a: Description of Completion Threshold
No. | Name | Description | Value Space | Default Value |
1 | Completed by Measure | Indicates that the Minimum Progress Measure is to be used (True or False) in place of any other method to determine if the activity has been completed. | boolean | False |
2 | Minimum Progress Measure | Indictes the minimum completion amount for the activity, normalized between 0..1 (inclusive). If the Attempt Completion Amount for the activity is defined and it is equal to or exceeds this value, the Attempt Progress Status is set to True and the Attempt Completion Status is set to True. If the Attempt Completion Amount for the objective is less than this value, the Attempt Progress Status is set to True and the Attempt Completion Status is set to False. The value is unreliable unless Attempt Completion Amount is available for the activity. | Real [0..1] Precision of at least 4 significant decimal digits | 1.0 |
3 | Progress Weight | A weighting factor applied to the Attempt Completion Amount associated with the activity used during rollup for the parent activity. | Real [0..1] Precision of at least 4 significant decimal digits | 1.0 |
Completed by Measure (False – default value): The Completed by Measure element indicates whether or not the Minimum Progress Measure element, along with the activity’s Attempt Completion Amount (e.g. progress measure), should be used to evaluate the activity’s completion, in place of any other method to determine if activity is completed satisfied (refer to Section 4.2.1.4: Attempt Progress Information).
If Completed by Measure element is True:
o If the Attempt Completion Amount for the objective equals or exceeds the Minimum Progress Measure, then the Attempt Progress Status is set to True and the Attempt Completion Status is set to True.
o If the Attempt Completion Amount for the objective is less than the Minimum Progress Measure, then the Attempt Progress Status is set to True and the Attempt Completion Status is set to False.
o If the Attempt Completion Amount for the activity is unavailable, the
Attempt Progress Status is set to False.
Minimum Progress Measure (1.0 – default value): The Minimum Progress Measure element indicates a threshold for attaining completion of the activity. This element contains a real value between –1.0 and 1.0, inclusive. The default value for the Minimum Progress Measure element, if not defined explicitly for the activity, is 1.0.
Progress Weight (1.0 – default value): The Progress Weight element provides a way for content developers to specify that the progress attained in one activity is more or less relevant than the progress attained in another activity. The Completion Measure Rollup Process (refer to Appendix C: RB.1.1. b) will calculate the weighted average measure of all of a cluster’s children to determine the normalized progress measure of the cluster. If the Progress Weight on the activity is defined as 0.0, the LMS will not consider the activity’s Progress Measure during the Completion Measure Rollup Process, even if the activity has a Progress Measure recorded.
