Full Question: I would like further information on the Diagnose, Intervention, Evaluation (DIE) Model, in terms of training student teachers. I have attempted to research the phrase, but not come up with guidance that I can use to share with my school for training and development.
Answer: “The DIiE model is embryonic – I have been exploring it to make the messages from Visible Learning more explicit and in the process of writing it up – although I have mentioned it a number of times. Diagnose – all too often schools introduce interventions prior to excellent diagnosis – both across the school, within the class, and for each student. A lot more student diagnosis is needed to best understand what they bring into the class – personified by the child’s skill, will and thrill (sense of motivation).
In our Visible Learning work we start with a needs analysis undertaken by all in the school (not just the principal) and this forms the basis for a) us validating these claims (the best way is to ask the students), b) it forming the basis for choosing the right intervention, and c) serves as baseline for later evaluating progress. Interventions – we are brilliant at this and there are millions of them, and 97+ percent work – in that they can be shown to improve student learning – but of course I want a higher benchmark than “increasing outcomes” – impact is more than achievement tests, it also involves whether schools are inviting places to come, affective and motivational, respect for self and others, etc. Implementation – I have added this to the DIE as too often excellent interventions have low fidelity of implementation. This is where models like Jim Knight’s coaching are powerful. It seems surprising that we have so few models of intervention in our sector (but see Michael Barber’s Deliverology, Tony Bryk’s Carnegie, Abe Wandersman’s Getting to Outcomes) and need to be much smarter at this. Evaluation – the core notion is evaluating our impact, and this is where the circle is closed as excellent evaluation is the starting point of superb Diagnosis” (John Hattie, personal communication, February 23, 2018).
