Users now have the option of including an Equation Editor when creating Constructed Response items. These tools allow students to construct equations to show solutions to assessment items rather than selecting a pre-formatted answer option. There are two versions of the Equation Editor tool: one for elementary and one for secondary students. Each equation editor is made up of symbols and mathematical functions, like basic operations, algebraic functions, and geometric tools.
*Note: This tool is not available on tablet devices at this time.
To add an Equation Editor to a Constructed Response item:
1. Click the drop-down to the right of “Constructed Response Type,” as shown in the following image.
2. Select either “Equation Editor Elementary” or “Equation Editor Secondary” from the drop-down menu.
3. Enter the item stem.
4. Click “Create.”
*Note: Creating a new version of an existing Constructed Response item allows users access to add an Equation Editor to the new version of the item.
The Elementary Equation Editor features fraction and mixed number buttons along with all basic operations including: addition, subtraction, multiplication, division, greater than, less than, and equal to signs, a dollar sign.
Displayed below are the fraction, mixed number, parenthesis, and bracket buttons included with the Elementary Equation Editor. These buttons may be utilized by students to build fractions, demonstrate order of operation skills, and demonstrate when to multiply specific numbers.
Below are the basic operations tools including greater than, less than, and equal to, or the approximation sign as well as the dollar sign.
The following image displays the Elementary Equation Editor as it appears in iTest. The editor tools appear at the top of the student response field, as indicated by the blue arrow.
Icons to allow students to undo, redo, or clear their response appear in the lower left corner of the student response field, as indicated by a pink arrow. As students construct a response, these tools may be used to remove and restore parts of a response, or to delete a response entirely prior to submission.
The Secondary Equation Editor includes symbols and functions similar to the elementary editor, with the addition of tools for exponents, square root (cube root, nth root), and absolute value.
Below are additional functions used for solving algebraic and geometric equations that are offered with the Secondary Equation Editor.
Lastly, the basic operations are available, along with inequality signs, and the plus or minus sign.
