Alignment "strength of fit" #6
Description
It seems to me that we should consider the addition of a new property for use with alignment object that identifies the strength of fit of the alignment. Unless a learning resource or an assessment instrument is specifically created to address a specific node in a competency framework, an alignment between an learning resource and a competency node will be at best "more or less" on target. However, without some means of signaling the precision or strength of the alignment, the assumption is that the alignment relationship is 1:1--a circumstance that is frequently not the case. This is a longstanding, well recognized problem with alignment (learning resource to competency node and competency node in one framework to competency node in another). To illustrate, the ASN has a set of properties for use with describing the strength of fit of an alignment between learning resource-to-competency framework node that demonstrate one solution--among a number of other possibilities:
