Re: Grading Graphing Questions
Posted:

I am a retired HS math teacher, and recall that the first consideration was consistency, so we made up a grading key for each question to be used by anyone grading the question. If the person got the answer correct, plotted the graph, labelled axes correctly, and showed the correct points of intersection, that might be considered to be appropriate work shown, to get full credit. If the student showed everything correctly that was specifically requested, I would accept that as acceptable. Using a calculator on a Regents exam may show the student a lot of data that he may not realize some teachers would like to see on the exam paper. There are differences of opinion among teachers that used to be rectified when regrading papers which were close to passing. Now I would be asgenerous as possible if the student has nothing wrong in his answer, gets all the required answers correct, and uses a mathematically acceptable approach..

I teach in a small school. There are four math teachers; each of us has one entire Regents or AP Course. Every year we have a discussion, when grading exams, about how much credit to give (or not) for graphing questions. Here's the situation:
Assuming the question is a nonpart I graphing question(such as graphing two lines, graphing two inequalities, graphing a parabola, graphing a parabola and a line), and the student draws the graph(s) correctly, labels everything, identifies point(s) of intersection or overlap of shading correctly, but does not show how they graphed the line or parabola, i.e., does not show a table, or the slope and intercept, or a test point for shading, Do you give full credit, or do you take off points because not enough work was shown?
The Scoring guide often indicates "appropriate work is shown" but what do you consider "appropriate work?" If this were a question on my own test, I would take off points for not showing the table, etc. to draw the graphs. However, this is the Regents . . . I do not want to be shorting my students of points that others could be receiving.
Any thoughts are greatly appreciated. ******************************************************************* * To unsubscribe from this mailing list, email the message * "unsubscribe nyshsmath" to majordomo@mathforum.org * * Read prior posts and download attachments from the web archives at * http://mathforum.org/kb/forum.jspa?forumID=671 *******************************************************************
