Value

An object of class MultipleChoiceTable

Arguments

identifier

A character representing the unique identifier of the assessment task. By default, it is generated as 'id_task_dddd', where dddd represents random digits.

title

A character representing the title of the XML file associated with the task. By default, it takes the value of the identifier.

content

A character string or a list of character strings to form the text of the question, which may include HTML tags.

prompt

An optional character representing a simple question text, consisting of one paragraph. This can supplement or replace content in the task. Default is "".

points

A numeric value, optional, representing the number of points for the entire task. It can also be calculated as the sum of points for individual answers, when provided. Default is 1.

rows

A character vector specifying answer options defined in rows of the table.

rows_identifiers

A character vector, optional, specifies identifiers of the rows of the table

cols

A character vector specifying answer options defined in columns of the table.

cols_identifiers

A character vector, optional, specifies identifiers of the columns of the table.

answers_identifiers

A character vector specifying couples of identifiers that combine the correct answers.

answers_scores

A numeric vector, optional, where each number determines the number of points awarded to a candidate if they select the corresponding answer. If not assigned, the individual values for correct answers are calculated from the task points and the number of correct options.

shuffle

A boolean value, optional, determining whether to randomize the order in which the choices are initially presented to the candidate. Default is TRUE.

shuffle_rows

A boolean value, optional, determining whether to randomize the order of the choices only for the first elements of the answer tuples. Default is TRUE.

shuffle_cols

A boolean value, optional, determining whether to randomize the order of the choices only for the second elements of the answer tuples. Default is TRUE.

feedback

A list containing feedback message-object ModalFeedback for candidates.

calculator

A character, optional, determining whether to show a calculator to the candidate. Possible values:

• "simple"

• "scientific".

files

A character vector, optional, containing paths to files that will be accessible to the candidate during the test/exam.
