In my professional context the remaining three technologies are inextricably linked - we don't currently have software which enables us to track our learners so we don't have any data to drive assessment or to analyse learning or even to offer prizes! I would love to do this but I suspect that the cost of tracking software (with the associated legal ramifications and headache) would pale into insignificant against the cost of effective analysis of the data it would produce let alone the effective use of the data analysis in order to drive assessment and target future learning.
If we were to change the software we use to provide good tracking data the other things we would have to do would include:
1. Retrospective 'coding' of existing questions to classify what skill, subject, knowledge and application they are testing
2. Retrospective and future 'coding' of our customers to enable two sided analysis
3. The development of an analysis methodology and the appropriation of software to support that
All of this could be very worthwhile to provide our learners with targeted resources, personalized analysis of their strengths and areas for improvement and to identify any globally weak / strong areas so we can target future developments BUT pragmatically I don't think our particular market is large enough to justify the costs associated with this.
Personally - I'm self obsessed enough to want to see analysis on my learning done by some formally recognized software! I am mercenary enough to want as many virtual badges and points as you can shovel in my direction!
