Major API Refactor: The API functionality has been refactored to require creating an Opal object for establishing a connection. Methods are now called on this object for interacting with the LMS API, replacing the previous function-based approach.
Added a verify_qti() function to validate XML
documents against the QTI v2.1 schema. Two schema versions are
supported: the original IMS Global schema and an extended version that
permits additional HTML tags.
Added new constructor functions assessmentTest(),
assessmentTestOpal(),
assessmentSection().
The default values of the “academic_grading” parameter/slot have
been updated in the functions assessmentTest(),
assessmentTestOpal(), test(), and in the
classes AssessmentTest and AssessmentTestOpal.
This parameter/slot is a named numeric vector that defines the grade
table shown to candidates as feedback at the end of the test. The
updated default follows the German grading system: gt <- c(“1.0” =
0.95, “1.3” = 0.9, “1.7” = 0.85, “2.0” = 0.8, “2.3” = 0.75, “2.7” = 0.7,
“3.0” = 0.65, “3.3” = 0.6, “3.7” = 0.55, “4.0” = 0.5, “5.0” = 0), where
each grade corresponds to the minimum percentage score required to
achieve it. To disable the grading table at the end of the test, set
this parameter to NA_real_.
Generic functions are now exported to allow advanced users to
extend the functionality of S4 classes (createItemBody(),
createResponseDeclaration(),
createOutcomeDeclaration(),
createResponseProcessing(),
createText()).
Added support for the preview_feedback option within
‘params’ in the YAML section of R Markdown files.
Renamed the service name in the keyring system credential storage to “rqtiopal”.
Renamed the “contributor” slot in QtiContributor to
‘name’.
QTIJS rendering (DirectedPair type, round Score and
Maxscore values).
Added a ‘<div>’ tag as a root child within the ‘itemBody’
element for Entry type tasks to ensure compatibility with
the LMS OpenOlat.
The functions qti_metadata() and
qti_contributor() have been deprecated. Use
qtiMetadata() and qtiContributor()
instead.
The ‘question_type’ column has been removed from the data frame
returned by extract_result(level = "item").
Fix parsing R Markdown files with tables according the latest pandoc version.
Fix extract_results(level="items") for
Ordering type, when candidate response is not
given.
Fix error at createQtitask(obj, zip=TRUE).
New API OPAL function get_course_elements() returns
dataframe with elements of the course by course id.
New API OPAL function get_course_results() returns
an xml with data about results by course id and node id.
New API OPAL function publish_courses() for
publishing a course by Resource ID.
method createQtiTask() can create XML or zip files,
to control this use parameter zip=TRUE.
QTIJS rendering shows feedback and score for tasks.
Handle problem with xsd scheme for xml validation.
Handle some problems with html and mathml entities.
Improved the appearance of the tasks in QTIJS viewer.
Added constructor functions for task classes:
singleChoice(), multipleChoice(),
essay(), ordering(), entry(),
directedPair(), oneInColTable(),
oneInRowTable(),
myltipleChoiceTable().
Added constructor functions for content of Entry class:
numericGap(), textGap(),
textGapOpal(), inlineChoice().
Added constructor functions for the feedback objects:
modalFeedback(), correctFeedback(),
wrongFeedback().
Added the ability to upload SURVEY resource type to Opal using
the API. The upload2opal() function now includes a new
parameter, “as_survey”, which allows you to specify the resource type.
Set “as_survey = TRUE” to upload as a SURVEY resource type.
Added the ability to put metadata in the manifest file for tests.
To store metadata information AssessmentItem and
AssessmentTest use slot “@metadata” that takes
QtiMetadata (and QtiContributor inside)
classes as type. Two construction functions have been added to create
objects: qti_metadata() and
qti_contributor().
Added the missing qti.js for rendering Rmd-files with tasks.
Added processing of the pandoc –embed-resources parameter for pandoc versions < 2.19.
AssessmentItem,
AssessmentSection and AssessmentTest objects
are checked for compliance with QTI requirements.
