    When creatilng a question in Calculated Formula, the question type governs the Answer and Answer Set display format only for the Instructor and does NOT enforce the input for the student.The system will take a student's answer and autocorrect to exponential values and grades the student as coorect. For example, if the instructor selects Normal Notation and the student enters an answer, other than Normal Notation, Learn converst their answer to Normal Notation and marks it as correct.

     

    The suggested idea is to have three desired formats:

    Variable Notation (when it doesn’t matter what type of numerical input a student uses. This appears to be the Blackboard default option.) Here the student inputs a number and Bb changes it to exponential. This seems to be the Default. The desired behavior is that Bb does NOT change the input. The student's input to the answer in should exponential. This default could be a choice rather than assumed.


    Mandatory Normal Notation (when normal notation is required for didactic reasons) This would be a choice where the student would have to input their answer as specified by the instructor and NOT changed by the system.


    Mandatory Scientific Notation (when scientific notation is required for didactic reasons). This would be a choice where the student would have to input their answer as specified by the instructor and NOT changed by the system.

    Here is
    ,a further example.  Let’s say that I asked the following question: 

     

    “Convert 1.23E2 into normal notation”

     

    The answer is 123 (This is the answer in “Normal Notation”)

     

    Learn would mark the following answers as correct because they are numerically the same as 123:  1.23E2, 12.3E1, 0.123E3 (I can site an infinite combination of inputs).  To make matters worse, Bb changes the student’s numerical input to “Normal Notation” even if they didn’t input their answer as such, because this was the answer input choice that was chosen.
