Timed map interpretation
The student is handed a map and a clock. It might be a topographic map to read for contours, relief, and gradient; a geologic or weather map to interpret; or three seismograms to triangulate an earthquake's epicenter. Working against time, they extract what the map shows and decide what it means — then justify the reading out loud. There is nothing to copy and no key to consult: the map is real, the time is real, and the interpretation has to hold up.
| Criterion | Not yet | Approaching | Mastered |
|---|---|---|---|
| Reading contours, relief & gradient | Cannot tell high ground from low or read a contour interval. | Reads elevation but misjudges gradient or relief between points. | Reads contour lines fluently — elevation, relief, and gradient — and pictures the terrain they describe. |
| Interpreting a geologic or weather map | Cannot connect map symbols to features or fronts. | Reads obvious symbols but misses what they imply about structure or weather. | Interprets a geologic or weather map's symbols into a coherent account of the structure or the forecast. |
| Triangulating an epicenter | Cannot read S–P arrival times or place a single circle. | Draws the circles but misplaces the epicenter or misreads a seismogram. | Reads S–P intervals from three seismograms and triangulates the epicenter, defending each distance. |
| Working under time pressure | Freezes or rushes into errors as the clock runs. | Makes progress but gets sloppy or loses track of the goal under time. | Stays deliberate under pressure — reading carefully and pacing the work to the time available. |
| Justification of the reading | States a reading the map does not support, or cannot explain it. | Gives a reading but cites only one feature, or hedges between two. | Defends the reading by pointing to the specific contours, symbols, or arrivals that support it. |
“The contours bunch up on the west face, so that’s the steep side; the stream runs down the valley where they point upstream. And from the three seismograms, the S waves lagged the P waves most at the third station, so it’s farthest from the epicenter — the circles cross just east of the ridge.”
“There are a bunch of lines close together, so it’s a hill, maybe? I’m not sure how to find where the earthquake was from the graphs.”
This assessment is AI-proof by design: it happens in the room, with a real map and a real clock. No chatbot can read a contour it was not given, triangulate from seismograms it cannot see, or decide what a map means while the timer runs. The maps differ from student to student, so there is no answer to look up — mastery is shown by reading and justifying in person, not by submitting.
