Audio Video Feedback Rich Media Efficiency Lookup
Actual matched assignment feedback production time contrast, written to video/audio; not learning quality or universal efficiency. Caller independently verifies learner/context/evidence and reference edition; not causal learning efficacy, disability eligibility or educational certification.
Description
Written and audio or video feedback production can be compared using matched assignment records.
Written and audio or video feedback production can be compared using matched assignment records.1
This tool reports the observed time difference without assuming equal feedback quality or a learning benefit.
When to use Audio Video Feedback Rich Media Efficiency Lookup
Use this tool to calculate or review the supplied observations under the stated rules. Establish the learning task, observed evidence and applicable framework or policy edition.
How to use Audio Video Feedback Rich Media Efficiency Lookup and understand its results
- Establish the learning task, observed evidence and applicable framework or policy edition.
- Enter observedWrittenFeedbackMinutes, observedMatchedRichMediaFeedbackMinutes, independentlyMatchedAssignmentFlags, using the field meanings and rules below, then run the tool.
- Read pairedRichMediaMinusWrittenMinutes, knownMeanFeedbackTimeDifferenceMinutes. Inspect nested result fields where present, and review unknown records separately from known matches.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedWrittenFeedbackMinutes | Observed written feedback minutes | list of number | Required |
| observedMatchedRichMediaFeedbackMinutes | Observed matched rich media feedback minutes | list of number | Required |
| independentlyMatchedAssignmentFlags | Independently matched assignment flags | list of number | Required |
Enter aligned nonnegative written and rich-media minutes plus binary independently-matched assignment flags. For known pairs compute rich-media minus written minutes and its arithmetic mean. At least one known pair is required; unmatched pairs are excluded without a separate unknown-count output. Negative differences mean rich-media production took less time.
difference_i=rich_i−written_i; mean=Σ_known difference_i/knownCount Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| pairedRichMediaMinusWrittenMinutes | Paired rich media minus written minutes | list of number |
| knownMeanFeedbackTimeDifferenceMinutes | Known mean feedback time difference minutes; preserve the subtraction order and sign defined in the mechanics | number |

}Limitations and assumptions
Supplied annotations and framework choices determine the result. The tool does not measure learning effects, assess learner intent or independently establish policy applicability.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Lists and matrices must be dense, without missing cells. Numeric lists allow at most 10000 entries; ordinary string lists allow at most 128 strings of 128 UTF-16 units each; numeric matrices allow at most 128 rows and 128 columns, subject to narrower requirements above.
