Arguments

section

A list containing AssessmentSection objects.

identifier

A character value indicating the identifier of the test file. By default, it is generated as 'id_test_dddd', where dddd represents random digits.

title

A character value, optional, representing the file title. By default, it takes the value of the identifier.

time_limit

An integer value, optional, controlling the time given to a candidate for the test in minutes. Default is 90 minutes.

max_attempts

An integer value, optional, indicating the maximum number of attempts allowed for the candidate. Default is 1.

fallback_titles

A character value, optional, controlling how titles are assigned when no explicit title is provided. Possible values are "filename" (use filenames as titles) and "generic" (use generic labels such as "Section 1", "Section 1.2", or "Task 1.2.1"). Default is "generic".

academic_grading

A named numeric vector that defines the grade table shown to the candidate as feedback at the end of the test.

Each grade corresponds to the minimum percentage score required to achieve it. A helper function german_grading() is available to generate a common German grading scheme.

The default is NULL, which means that no grading table is shown. To display a grading table, provide a named numeric vector or use german_grading().

grade_label

A character value, optional; a short message that shows with a grade in the final feedback; for multilingual use, it can be a named vector with two-letter ISO language codes as names (e.g., c(en="Grade", de="Note")); during test creation, it takes the value for the language of the operating system; c(en="Grade", de="Note")is default.

table_label

A character value, optional; a concise message to display as the column title of the grading table in the final feedback; for multilingual use, it can be a named vector with two-letter ISO language codes as names (e.g., c(en="Grade", de="Note")); during test creation, it takes the value for the language of the operating system; c(en="Grade", de="Note")is default.

navigation_mode

A character value, optional, determining the general paths that the candidate may have during the exam. Two mode options are possible: - 'linear': Candidate is not allowed to return to previous questions. - 'nonlinear': Candidate is free to navigate; used by default.

submission_mode

A character value, optional, determining when the candidate's responses are submitted for response processing. One of two mode options is possible: - 'individual': Submit candidates' responses on an item-by-item basis; used by default. - 'simultaneous': Candidates' responses are submitted all together by the end of the test.

allow_comment

A boolean, optional, enabling the candidate to leave comments in each question. Default is TRUE.

rebuild_variables

A boolean, optional, enabling the recalculation of variables and reshuffling the order of choices for each item-attempt. Default is TRUE.

show_test_time

A boolean, optional, determining whether to show candidate elapsed processing time without a time limit. Default is TRUE.

calculator

A character value, optional, determining whether to show a calculator to the candidate. Possible values: - "simple" - "scientific".

mark_items

A boolean, optional, determining whether to allow candidate marking of questions. Default is TRUE.

keep_responses

A boolean, optional, determining whether to save the candidate's answers from the previous attempt. Default is FALSE.

metadata

An object of class QtiMetadata that holds metadata information about the test. By default it creates QtiMetadata object. See qtiMetadata().

points

Do not use directly; the maximum number of points for the exam/test. It is calculated automatically as a sum of points of included tasks.

Value

An AssessmentTestOpal object.
