Discrepent event interview -
Exploration Of The Temperature Of Different Objects
- The discrepent event starts after the student arranged the objects in order from the coldest (styrofoam ball) to hottest (aluminium cube).
- Then the temperature of the objects is taken with an electronic thermometer and displayed in real time on a computer screen as a decimal number in a chart and as a line on a graph.
- When the data doesn't fit the student's expectations the interviewer has him take some more readings, asks some probing questions to assess how close the student was to a scientific understanding.
- Having assessed what was believed to be the student's understanding and what might be missing from the student's understanding, the interview was ended after the student replied ... weird...
Enjoy!
