Essential Requirements of Task
- Identify and interpret specific data in graph captions
- Estimate (to with 0.5 minutes) the time associated with a point
- Estimate (to within 2 degrees) the temperature associated with a
point
- Associate comment events with points on the graph
- Justify event-point associations using by recall
- Justify event-point associations by relating to anchor
associations
on the scale
- Justify event-point associations by ordering relative temperatures of
events
- Justify that more than one event may be associated with a peak/valley
- Relate the shape of the graph to rate of change
- Compute a numerical estimate of the rate change of temperature
between
two points
- Estimate the number of temperature readings taken during a time
period
- Estimate the time elapsed between two points
- Estimate change in temperature (magnitude and direction) between two
points
Major Flaws
- Incorrectly reports the temperature or time associated with a point
- Associates an incorrect unit of time measure with the horizontal scale
- Confuses events measured Fahrenheit with those measured in Celsius
- Incorrectly pairs events with peaks and valleys
- Cannot provide clear justifications for event-point associations
- Omits an entire task
- Confuses the measures of time-location with those of time-duration
- Uses the wrong units in reporting the rate of change
- Does not use most of the available data in computing the rate of
change
Minor Flaws
- Incorrectly distinguishes between the lower of two relatively close
valleys
- Incorrectly distinguishes between the higher of two relatively close
peaks
- Incorrectly distinguishes between the greater of two relatively high
rates
of change
- Fails to report one part of the date (day, month, year)
- Fails to report one event-point association
- Fails to justify one of the two most confident
associations
