Aesthetic Development Interview
VTS's main instrument is a non-directive interview, the Aesthetic Development Interview or ADI, that involves showing subjects a reproduction of a work of art and asking them to talk about it as though thinking out loud. This interview is tape-recorded, transcribed, and parsed. A sampling of thought units is coded using a manual covering thirteen different domains of thinking that was derived over a fifteen-year period using the same interview protocol. We further study each interview in context to understand how each thought unit fits into an over-all pattern of thinking.
Because of consistent teacher reports that the students write more and better as a result of their VTS discussions, writing assignments are collected and analyzed. They are also used as part of VUE's teacher professional development program as they provide evidence of growth in writing and critical thinking skills.
Material Object Interview
Originated from the Aesthetic Development Interview (ADI), the Material Object Interview (MOI) utilizes a material object such as a coin, a fossil, or a map in place of a work of art to elicit thoughts. As with the ADI, this non-directive interview follows the same procedures of collecting, coding, and analysis.
