The Numeric Entry Module provides an entry space for numeric values. The module "understands" math in that various forms of a number will be accepted by the system. For example, 100 and 1.00 x 102 are graded equivalently. The module contains two potentially gradable fields—the numeric entry field and the units field. Each of these can be configured separately, and global options can be set for the entire module.


Additionally, tolerances can be set that allow for rounded numbers to be accepted as correct within a defined range.


Options

Click anywhere on the edge of the module to open the Options panel. The Options panel contains the following elements:



 

  1. Show units. Shows or hides the units field. To change the units of measure, click the text area Units and type the desired abbreviation.
  2. Graded. Sets the grading policy for units. Check to make sure the units field is graded.
  3. Use dollar units. Shifts the units to the left of the answer space and uses the dollar sign ($).
  4. Revert. Removes any changes made to this module in the current tab.
  5. Grading Status. Changes the module between static , graded , and interactive .
  6. Delete. Removes this module from the stage.

 

Numeric Entry Tools

Click in the numeric entry field to open the Tools panel. The Tools panel contains the following elements:


  1. Scientific notation. Enters 10 to a blank power for scientific notation. (Shortcut: enter "x" or Shift-8 on the keyboard.)
  2. Create algo. Highlight text or number(s) and click to make algorithmic variables.
  3. Insert-algo menu. Click the green arrow to view and select available algorithmic variables from the drop-down menu.
  4. Grading Status. Indicates that the entry space is always graded.


Units Tools

Click on the word Units to open the Unit Tools panel. The Units Tools panel contains the following elements:



 

  1. Superscript. Highlight and click to superscript text or click to open the superscript editing area (Shortcut: Shift-6). Note: this editor provides a special feature that allows for multi-level superscripting. To escape superscript mode, use the right keyboard arrow or click on the main line.
  2. Parentheses. Enters parentheses.
  3. Angstrom. Enters the Angstrom symbol.
  4. Mu. Enters the Greek letter mu.
  5. Ohm. Enters the symbol ohm.
  6. Degrees Celsius. Enters symbol for degrees C.
  7. Degrees Fahrenheit. Enters symbol for degrees F.
  8. Italic. Highlight text and click to make text italic.

 

Setting tolerance

Tolerances can be set for Numeric Entry to allow for rounding and approximations. The system defaults to 2% tolerance. A degree of difference accepted as approximately accurate within a problem. To change the tolerance, go to the Correct tab or an Incorrect tab and click on the gray outer portion of the module to open the Grading options. The Grading options include the following elements:



 

  1. Tolerance field. Entry field for percent or numeric tolerance.
  2. Infinity. Accepts any number above or below the number entered by the author.
  3. Percent. Allows for setting a percent above and below the number entered by the author.
  4. Numeric. Allows for setting a numeric tolerance above and below the number entered by the author.
  5. Exact. Accepts only the exact number entered by the author.


In this example, any value greater than 4 will be accepted. Because infinity is selected in the (+) field when the answer is marked as 4. The (-) field has a tolerance of 0 so any number lower than 4 will be not accepted.
