A three axis model

Taking the ideas from the previous post and putting them into a diagram I get this

Some assessment uses ICT (or technology) – this is e-assessment (x axis).

Some assessment is designed to assess ICT capability (y axis).

Elliott’s Assessment 2.0 seems to be using ICT, not as e-assessment, but as a medium for allowing judgement to be made about the ICT capability (z axis).

Now of course, analysing any one particular assessment methodology one could locate it in this three-dimensional space. for example:

A traditional written paper would be on the y-axis. The NAA online assessment activities designed for KS3 would be in the space between all three axes (with perhaps a lower y- and z-values than x-value. Coursework would have an x-value of 0 but would have some components of y and z. Online assessments such as the driving test would be on the x-axis.

My questions here are “Where is the highest validity”? and “Where is the highest reliability?”. How does one use Elliott’s Assessment 2.0 to determine success in a certificated qualification?

  1. “My questions here are “Where is the highest validity”? and “Where is the highest reliability?”. How does one use Elliott’s Assessment 2.0 to determine success in a certificated qualification?”

    Before I stab an answer at this, I feel I need to ask what are we asessing? When we know that, I hope the answer will be clearer.
