A student can right-click (Control-click on Macintosh) in the Equation Editor to open the palettes. From the Matrix palette, the student must select the appropriate size of matrix (see Figure 8. 9). Then, they must fill in the values for the matrix entries. 110 · 8 Authoring Methods for Questions Figure 8. 9: Using the Matrix Palette Note: One of the skills tested with this question is determining the appropriate matrix dimensions. With the more limited Matrix question type, the size of matrix is already fixed, and the student simply enters the matrix entries.

The grading of the student response checks whether the determinant of the student's matrix is non-zero. This question is created in the Question Editor as a Maple-graded question. 8. 6 Question Authoring in the Question Editor · 111 To create the question: 1. In the Enter Maple code that evaluates to the correct answer region, enter M:=Matrix([[1, 2], [3, 4]]): printf(MathML[ExportPresentation](M)); c. In the Enter Maple code to grade the student response region, enter x:=LinearAlgebra[Determinant]($RESPONSE): evalb(type(x, numeric) and x<>0); d. From the Select the type of expression you want to accept field, select Maple Syntax because students will be entering a matrix. From the Text/Symbolic entry field, select Symbolic entry only so that students can use the Equation Editor to create the matrix rather than having to enter the Matrix command. Add the question to one or more question groups, and then click Submit. 112 · 8 Authoring Methods for Questions Figure 8. 10: Invertible Matrix Question For more information on Maple code, refer to your Maple system documentation. Tutorial: Working with Multipart Questions This tutorial describes: · Editing General Information (page 113) · Adding and Editing Individual Question Parts of a Multipart Question (page 113) · Partial Credit and Weighted Scoring (page 113) For an introduction to multipart questions, see Multipart Questions (page 162). For instructions on creating a new multipart question, see Multipart Questions in the Question Editor (page 99). 8. 6 Question Authoring in the Question Editor · 113 Editing the Top Level of a Multipart Question 1. On the Question Name & Type screen, edit the description, solution, or other options. On the Question Statement & Weighting screen, you can: · Edit the text to appear at the top of the question · Specify preferences for numbering the parts using the Numbering style drop-down menu. Adding to and Editing Individual Question Parts of a Multipart Question If your question includes variables, you must edit the plain text script file for it to preserve your variable definitions. You can edit the script file by using the Question Editor Edit Source facility. Setting Partial Credit and Question Weighting in a Multipart Question You can set the weighted scoring of individual question parts in a multipart question. To set the weighting for each component part of a multipart question: 1. On the Question Statement & Weighting screen, update the weighting. That is, if there are x parts in the question, each part is weighted 1/x of the total value assigned to the question in an assignment.
