## Math and Science Notations on Blackboard

Blackboard has Message Box features in its different functionalities. For example, creating annoucement, building items, creating assignments, or building test. The ribbon at the top of the Message box, right under the "Subject" box, has multiple options to choose from to include in the message. It can be regular text with different font type and size, or add audio and video files, or mathematical notations and symbols.

The mathematical notations and symbols are mostly uselful to create assignments, test
questions and test options that require those notations in math and sceinces. To create
those equations, you have to select the mathematical symbol option that is shown with
the "*f _{x }" *symbol

**NOTE: the WIRIS math editor does not work well, and sometimes at all, with the Microsoft Office equation editor or the Google Docs equation editor. If you do attempt to use it, please check very closely for errors.**

* *

If you don't see the "*f _{x }" *symbol, it might be because your message box is compressed. To show all text style
options, click the double drop down arrow at the to right of the message box.

Clicking the math equation option gives you a new window to write your mathematical equations on.After you write your equation, you click "Accept" to add the equation to the message, question item, or answer option you are writing, or you click "Cancel" to disregard it.

If the symbol you want to include in different from what you see in the general symbols
options, you might need to click on the other options that are on the top raw which
will give you many more symbol options in that domain. For example, arrows, Greek
symbols, matrices, and more.

There are more options than the ones seen in the above images. Hoover over each domain option on the top row and see what other options are available to make your equation complete.

If you are creating mathematical question, the question item can include formula, text, equations, and anything you want to include in it. See the example below:

If you create a multiple choice item using mathematical notations, and if the answer options also need to use those notations, you can create the eqautions same way as you did for the question item.

For science subjects that use a different subject related symbols, you can use a software, or applications that are used in the descipline and you can copy the formula from the software or application and paste it on blackboard.

## Creating Calculated Formula Questions

A Calculated Formula question allows instructors to create questions with varying
numerical values based on an instructor-determined formula. To create a calculated
formula question, open the test canvas and click on Create Question,** **and select Calculated Formula from the menu. When the question page opens, add question text that includes variables
in square brackets [x] corresponding to variables in the formula that will be used
to calculate the answer to this question.

Answers are not part of the formula because answer sets are automatically calculated. Variables must consist of letters, but "pi" and "e" are reserved and cannot be used as variables. The answer formula for the example question in the image above will look as seen below.

After intering the question and answer formula, define the correct answer range, plus or minus a numeric or a percentage variation
from the exact answer. If the correct answer must be exact, the range should be 0.
If partial credit is allowed, define the broader range for partial credit and the
percentage of the total points that will be given if the answer is within the partial
credit range. For example, units can be required as part of the answer, and a student
may lose points if the units are missing or are incorrect. After completing the fields
on this page to calculate answer sets and provide response feedback, click **Next**.

The next step is defining your variables and answer sets. Variables can be expressed in either normal or exponential notation. For example, -0.0001 can be written as 1.0e-4 or as 1.0E-4 without spaces. Studennts' answeres can also be expressed in standard or exponential notation.

Specify the the minimum and maximum values for all your variables, and at the answer
set option, specify the number of decimal places or significant digits to calculate the answer
to and the possible number of answer sets to generate to students. You can make every stduent
get a different value for each variable by specifying the number of answer sets the
same amount as the number of students taking the test.

You can then click **Calculate** to generate new answer sets , or **Next** to go to the next page to adjusting the number of answer sets as required but without
recalculating existing answer sets if answer sets have already been generated. Click **Back** to go back to the previous page. Click **Cancel** to quit.

You will now be able to view the system generated answer sets. You can change any
of the variable values by inputing new values, To remove an answer set, click the **Remove** button. If you change any variable values, click the **Calculate** button to calculate new answer values.

Once you are done creating your question, you can submit and close or submit and create a new calculated formula question.
