Answer types¶

There are two levels for setting the type of answers in a question: at the question level, with a uniform type for all answers in the question, or within each answer environment.

Hence a question can contain answers of different types, in particular some can be of type multiple choice and others of input field types (see Different Answer Type).

There are Multiple Choice problems of different types: unique, multiple, yes-no, .... For details see the corresponding paragraph below. Do not confuse the term "type of MC-problems" with the term "type of answers".

(see Different Answer Type)

Setting the type is done by the \type{...}-command, and the position of the command determines how it works.

Example 1 (one type for all answers fields):

\begin{question}
    \type{input.number} % set for all answers

    \begin{answer}
        ...
    \end{answer}

    \begin{answer}
        ...
    \end{answer}

\end{question}

Example 2 (possibly different types for each answer):

\begin{question}
    \type{input.generic} % optional 

    \begin{answer}
        \type{input.number} % this answer has to be a number
        ...
    \end{answer}

    \begin{answer}
        \type{input.function} % this answer is a function
        ...
    \end{answer}

    \begin{answer}
        \type{mc.multiple} % this answer block consists of a task with MC-choices.
        ...
    \end{answer}

\end{question}

In the second example, the command \type{input.generic} can be omitted, but each answer environment needs to have a \type{...}-command. It is not possible to set a specific type on question level and just overwrite it for some answers.

Input types¶

More detailed information on input field questions can be found under the following link: Overview input field questions

Here is just an overview of the types:

Type	Preview
input.number example and detailed explanation
input.finite-number-set example By default only numbers (e.g. 1, 5, 1.2, 2/3) are accepted values for the user input. With the command \allowForInput the set of valid symbols for the input can be extended. That allows for example to ask for multiple of pi: \allowForInput{+ - * / pi}.
input.function Compare the user's answer numerically with the pre-given solution or subject to given conditions example and detailed explanation
input.cases.function Designed for case differentiations of e.g. absolute value functions. Note that you can only use this input type in an answer environment. example and detailed explanation
input.interval By default only numbers (e.g. 1, 5, 1.2, 2/3) are accepted values for the user input. With the command \allowForInput the set of valid symbols for the input can be extended. That allows for example to ask for multiple of pi: \allowForInput{+ - * / pi}. example and detailed explanation
input.matrix If the solution to a question is a row vector, a column vector or a matrix, the generic problem is of the type input.matrix. example (cross product) and detailed explanation Use checkAsFunction for comparing matrices with (multivariate) functions as matrix entries. example (Jacobian matrix)
input.text examples and detailed explanation
input.truth-table The boolean values can be changed by mouse click example and detailed explanation

Multiple Choice types¶

Graphics types¶

For question which are solved by interacting with a visualization, there are the answer types

• \type{graphics.number},
• \type{graphics.function} and
• \type{graphics.matrix}.
