Conventional evaluation privileges short-term outcomes (if it gets to outcomes at all). This is unavoidable. As a teacher I used to think that the true results of my efforts would be seen five-ten-fifteen years down the road. But my university needed to know how good a teacher I was every quarter or every year, so remedial action could be taken or my good/bad teaching could be factored into my next pay raise or promotion. How my students did fifteen years later was the true test, but the time frame was wrong for what the university had to do.
