Economics Graphing Tool Directions

Instructor Notes

We often find that challenges students experience are related to skipping the directions and tutorial assignment, so we strongly recommend assigning the Tutorial activity in Smartwork5. If your students experience further challenges with Smartwork5 or with the graphing tool, please have them submit a help desk ticket.

Directions on how to use the graphing tool may be found here; the tutorial questions are available as an assignment titled “Smartwork5 Tutorial.” Video walkthroughs for each question type may be found here.

The notes below are intended to help you answer some common questions your students might have.  This information is also included in the student directions.

1.  I believe I answered the question correctly/my answer looks like the solution, but I was graded incorrect.

Ensure that your student carefully read the directions to the question.  Some questions require students to take two distinct actions; for instance, plotting points with the point tool and then plotting a curve with the curved-line or straight-line tool.  If the student plotted the curve but not the points, the question will be marked incorrect.

2.  The question told me to shift the line, so I drew it in the correct area but was marked incorrect.

Shifting questions require the student to pick up and move the curve(s) that exist on the screen, rather than drawing new ones.

3. Instead of picking up an entire curve to shift it, I picked up the midpoint/endpoint and shifted that, and was marked incorrect.

While it is possible to move the midpoint/endpoint of a curve, questions that instruct the student to drag the curve require that the student drag the entire curve, not just one segment.  To answer this question correctly, the student needs to pick up the entire curve rather than a single point.

4. When I click on a point, the coordinates don’t match what I see when I hover over the point – for instance, when I click I see (0,0) but when I hover I see (0, 0.2).

We don’t want students to be marked incorrect because they have clicked the tiniest margin off of the correct point, so our graphing system includes a snap feature.  Questions default to having snap enabled, though in some cases an author may turn it off (you can see this by looking at the question in the authoring view). When snap is enabled, all points will be pulled to the nearest half-increment – so a point placed at (0, 0.2) on a graph with axis increments of 1 will be pulled to (0,0).  This is why the coordinates the student sees when hovering may sometimes be different from those they see when clicking.

5.  At any time, should you wish to reset a student’s attempts on a question, you may do so by following the directions here.
