New Quizzes: Allow Only Numeric Values for Numeric Questions

    In classic Quizzes, if a student tries to enter a non-numeric value for a numeric question, their answer is rejected and they receive the following error message saying that "only numerical values are accepted":

    In New Quizzes, non-numeric values (excluding - negative numbers) were previously rejected for numeric questions. If the student tried to submit the quiz after entering non-numeric values, they received a message saying that they had unanswered questions. But as of around February 2019, New Quizzes has backtracked on this ability and now students can submit any type of value (letters, symbols, etc) in the answer field. 


    This is a problem because students can answer a numeric question with the right numeric value, but if they include any extra characters or symbols, their responses will be marked incorrect.


    For example, in the question below there are multiple ways in which students might correctly respond:

    Possible answers could include 3.20, 0.032, 3.2%, 3.20 percent, or the fraction 8/25.


    Instructors can specifically tell students to only respond in numeric values with no additional symbols for each question. But unless the response field itself rejects non-numeric values and/or gives an error message, students will inadvertently respond with extra text or symbols. While instructors have the ability to add multiple "Possible Answers" for numeric questions, they can only enter numerical values for the answer fields, not letters and symbols. 



    It doesn't make sense that students can enter non-numeric values as answers while instructors cannot. This also creates an undue burden for instructors as they have to anticipate every possible way in which a student might respond to the question. 


    To have feature parity with classic Quizzes, New Quizzes should only accept numeric value responses (excluding the negative sign -  and scientific notation ^) for numeric questions.
