High-Performance Open-Source Archive
Replaced platform-specific external SHA1 commands in tests with an R-native hash implementation to improve portability across operating systems.
Fixed MathJax rendering for dynamically loaded referent content in QTI.JS.
Added support for OpenOlat via a new class
AssessmentTestOpenOlat. It introduced OpenOlat-specific
configuration options (e.g., navigation behavior, visibility settings,
number of attempts) as slots and corresponding arguments in
assessmentTestOpenOlat().
Added fallback_titles argument to
test() and test4opal() to control how section
and item titles are assigned when not explicitly provided. Supported
values are “filename” and “generic”. The AssessmentTest
class now includes a fallback_titles slot.
Added a new slot scoring_scheme to the
SingleChoice class to control how response options are
scored. Supported values are “standard” (default) and “penalty”.
Introduced penalty-based scoring for single-choice tasks. When
scoring_scheme = "penalty", incorrect answers receive a
negative score of -points/(k-1), where k is the number of response
options. This ensures that random guessing yields an expected score of
zero.
Added a new stylesheet_path slot to
AssessmentTest objects, allowing users to include custom
CSS stylesheets at the assessment test level. When academic_grading is
enabled, the default styles/rqti.css stylesheet is included
automatically, and custom styles can be added to override the default
appearance.
Added german_grading(), a helper function that
returns a predefined German grading scale for the
academic_grading argument in test() and
test4opal(), avoiding the need to manually define grading
vectors. This grading scheme can also be stored directly in the
academic_grading slot of AssessmentTest
objects.
Added helper provide_file() to embed local files
directly into .Rmd tasks as # Base64-encoded hyperlinks for downloadable
attachments.
section() now supports Rmd files created with the
exams package. Such files are automatically detected and
converted to QTI 2.1 XML via exams::exams2qti21(), so they
can be used directly without additional wrapping.
Added exams_task() helper for explicit control over
exams-based tasks. While section() can handle exams .Rmd
files automatically, exams_task() can be used when
additional control is needed, e.g., to assign a custom title. The
function converts the Rmd file and returns the path to the generated XML
file in a temporary directory, allowing combination with native rqti
items.
Enhanced LMS Opal API with new functions
getCourseGroups() and getGroupUsers() for
retrieving course groups and group users as data frames.
Enhanced verify_qti() to support different input
types, provide more informative validation messages, and use both
xmllint and xml2 backends for XML
validation.
extract_results(level = "task") now includes an
additional column containing scorerComment for manually
scored item results.
Images referenced in external XML files are now automatically embedded as Base64. This ensures that tasks are fully self-contained and do not depend on external image files.
Changed the default time_limit for
AssessmentTest and AssessmentTestOpal objects
(and for all related helper functions) to NULL, so time limits are no
longer set at the test level by default.
Changed the default value of allow_paste in
Essay items to TRUE.
Fixed handling of consecutive gaps in .Rmd tasks.
Fixed identifier validation regex to correctly allow hyphens in valid identifiers.
Fixed test() and test4opal() to
correctly handle input provided as a list containing a single
section.
RQTI_API_USER environment
variable. If api_user is not provided explicitly, its value
is now read from the environment.Fixed an issue in upload2opal() where arguments
open_in_browser and as_survey were not
forwarded to upload2LMS().
Fixed problems in auto-generated scripts via RStudio template.
Fixed parameter serialization in dropdown() to
preserve long values, normalize numeric and logical formatting, and
ensure stable, test-consistent gap interaction output.
Rendering functions (render_qtijs(),
render_xml(), and render_zip()) now accept a
qtijs_path argument (defaulting to
qtijs_pkg_path()), allowing explicit control over the qtijs
installation path.
Added a daemon argument to
start_server() for improved server control.
Exported the qtijs_pkg_path() helper function for
accessing the qtijs installation path.
Improved error and warning messages for duplicate identifiers.
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.
