Course tests
:: services/crstests module

This module enables users to view and edit course tests.

Course test enables lecturers to give points and grades to their students. We use a rooted tree to represent a course test. We use course test, and tree terms interchangeably.

Vocabulary:

  • test - course test
  • test ID - the ID of the root of a particular test
  • template - a test not connected to a course edition
  • template ID - ID of a root of a particular template

Node types

There are 4 node types: RootNode, FolderNode, TaskNode, GradeNode.
  • RootNode - RootNode can have sons of type: FolderNode, TaskNode, GradeNode.
  • FolderNode - A folder node is used to logically organize other nodes. Eg. You can have a folder node for each written quiz. Such folder could have many TaskNodes as sons representing single tasks at such quiz. FolderNode can have sons of type: FolderNode, TaskNode, GradeNode.
  • TaskNode - Points can be given in this type of node. So it should be used for such activities as homework, quizzes, single tasks inside quizzes, etc.
  • GradeNode - Grades can be given in this type of node. Each GradeNode has associated grade type. It can be used to give final grades for the semester. For further info about grade types see services/grades/grade_type method.

Additional information

  • Nodes of type TaskNode, GradeNode can only be leaves of the tree (can't have any children).
  • Each node has a property called 'order' it should be used to sort children of some node, so that each time the tree is displayed children are in the same order.
    • Exemplary test tree:

    Grades and points

    The goal of the course test is to be able to give grades and points to students. Grades and points are associated with nodes. To represent grades and points we introduce two objects:
    TestGradeObject - a dictionary representing a grade:
    • node_id - ID of the node.
    • student_id - ID of the student that got this grade.
    • grader_id - ID of the user that gave this grade or null if the grader is not set
    • grade - dictionary describing given grade. The structure will be same as the structure of elements of the 'values' array of services/grades/grade_type method.
    • last_changed - a DateTime string (see datatypes). Date and time of last modification or null ""
    • private_comment - Grader's comment, which should not be visible to the student.
    • public_comment - Comment intended for a student.
    TestPointsObject - a dictionary representing points:
    • node_id - ID of the node.
    • student_id - ID of the student that got this point.
    • grader_id - ID of the user that gave points or null if the grader is not set.
    • points - Number of points the student got.
    • last_changed - a DateTime string (see datatypes). Date and time of last modification or null ""
    • comment - Comment intended for a student.

    Automatic grading

    Points and grades given at some node (TaskNode or GradeNode) can depend on points or grades given in other nodes. Eg. a grade at the end of semester can depend on the sum of points of all the quizzes in that semester. TaskNode and GradeNode support this kind of dependency. These dependencies can be used to automatically calculate some grades of points. We call this automatic grading. Eg. lecturer can write algorithm to give final grades, it can depend on the sum of points student got over the semester. There is a custom programming language used to code such algorithms. Such algorithm can have dependencies on others nodes which are bind to variables. It can also have public constant variables. Please note: For the time being this module doesn't concern itself with executing such algorithms. Therefore result of methods such as node_grades, node_points will only contain points and grades set with update_points, update_grades

    Permission model

    Of course we don't want any student to see the grades or points of the other students. Therefore there is a permission system needed. There are 6 types of permissions users can be granted: ReadPerm, ModStructure, ModPermissions, ModPoints, ModGrades, ModGroupPoints. To represent the permission in method parameters and results we use:

    PermissionObject

    Each PermissionObject is a dictionary with at least these fields:
    • name field equal to the name of permission type it represents
    • user_id field containing ID of the user that this PermissionObject concerns.
    Additionally, if a particular PermissionObject represents ModGroupPoints type it should contain two more fields:
    • course_unit_id
    • group_number
    These two fields should identify a class group (see vocabulary). We will describe each of these permissions separately:
    • ReadPerm This permission can only be granted in RootNodes. It specifies if a user can access all the data in the test represented by a RootNode. You must grant this permission if you want to grant other permissions. name field for this type of permission will be equal to 'read'.
    • ModStructure This permission can only be granted in RootNodes. It specifies if a user can manipulate structure of the test represented by a RootNode i.e. add nodes, delete nodes, change properties, etc. name field for this type of permission will be equal to 'mod_structure'.
    • ModPermissions This permission can only be granted in RootNodes. It specifies if a user can manipulate permissions of the nodes in a test. name field for this type of permission will be equal to 'mod_permissions'.
    • ModPoints This permission can only be granted in nodes of type RootNode, FolderNode, GradeNode. It specifies if a user can change points (in a particular node) of all the students that a test concerns. name field for this type of permission will be equal to 'mod_points'.
    • ModGrades This permission can only be granted in nodes of type RootNode, FolderNode, GradeNode. It specifies if a user can change grades (in a particular node) of all the students that a test concerns. name field for this type of permission will be equal to 'mod_grades'.
    • ModGroupPoints This permission can only be granted in nodes of type RootNode, FolderNode, TaskNode. This permission concerns particular class group. It specifies if a user can change points (in particular node) of all the students of that class group. name field for this type of permission will be equal to 'mod_group_points'.

    Permission invariants

    Among all the permissions ReadPerm, ModStructure, ModPermissions only concern root nodes. For all others permissions the following invariant must be satisfied. If a particular permission is granted in some node then it also must be granted in all the nodes in the subtree that the permission concerns. For example, if a ModPoints permissions is granted in root node for some user, then it must be granted in all the nodes in the tree of type different than GradeNode. When you change some permissions in some node, then some permissions might be added and some might be deleted to satisfy this invariant.
