**********************************************
XML format of drag and drop input [inputtypes]
**********************************************
.. module:: drag_and_drop_input
Format description
==================
The main tag of Drag and Drop (DnD) input is::
<drag_and_drop_input> ... </drag_and_drop_input>
``drag_and_drop_input`` can include any number of the following 2 tags:
``draggable`` and ``target``.
drag_and_drop_input tag
-----------------------
The main container for a single instance of DnD. The following attributes can
be specified for this tag::
img - Relative path to an image that will be the base image. All draggables
can be dragged onto it.
target_outline - Specify whether an outline (gray dashed line) should be
drawn around targets (if they are specified). It can be either
'true' or 'false'. If not specified, the default value is
'false'.
one_per_target - Specify whether to allow more than one draggable to be
placed onto a single target. It can be either 'true' or 'false'. If
not specified, the default value is 'true'.
no_labels - default is false, in default behaviour if label is not set, label
is obtained from id. If no_labels is true, labels are not automatically
populated from id, and one can not set labels and obtain only icons.
draggable tag
-------------
Draggable tag specifies a single draggable object which has the following
attributes::
id - Unique identifier of the draggable object.
label - Human readable label that will be shown to the user.
icon - Relative path to an image that will be shown to the user.
can_reuse - true or false, default is false. If true, same draggable can be
used multiple times.
A draggable is what the user must drag out of the slider and place onto the
base image. After a drag operation, if the center of the draggable ends up
outside the rectangular dimensions of the image, it will be returned back
to the slider.
In order for the grader to work, it is essential that a unique ID
is provided. Otherwise, there will be no way to tell which draggable is at what
coordinate, or over what target. Label and icon attributes are optional. If
they are provided they will be used, otherwise, you can have an empty
draggable. The path is relative to 'course_folder' folder, for example,
/static/images/img1.png.
target tag
----------
Target tag specifies a single target object which has the following required
attributes::
id - Unique identifier of the target object.
x - X-coordinate on the base image where the top left corner of the target
will be positioned.
y - Y-coordinate on the base image where the top left corner of the target
will be positioned.
w - Width of the target.
h - Height of the target.
A target specifies a place on the base image where a draggable can be
positioned. By design, if the center of a draggable lies within the target
(i.e. in the rectangle defined by [[x, y], [x + w, y + h]], then it is within
the target. Otherwise, it is outside.
If at lest one target is provided, the behavior of the client side logic
changes. If a draggable is not dragged on to a target, it is returned back to
the slider.
If no targets are provided, then a draggable can be dragged and placed anywhere
on the base image.
Targets on draggables
---------------------
Sometimes it is not enough to have targets only on the base image, and all of the
draggables on these targets. If a complex problem exists where a draggable must
become itself a target (or many targets), then the following extended syntax
can be used: ::
<draggable {attribute list}>
<target {attribute list} />
<target {attribute list} />
<target {attribute list} />
...
</draggable>
The attribute list in the tags above ('draggable' and 'target') is the same as for
normal 'draggable' and 'target' tags. The only difference is when you will be
specifying inner target position coordinates. Using the 'x' and 'y' attributes you
are setting the offset of the inner target from the upper-left corner of the
parent draggable (that contains the inner target).
Limitations of targets on draggables
------------------------------------
1.) Currently there is a limitation to the level of nesting of targets.
Even though you can pile up a large number of draggables on targets that themselves
are on draggables, the Drag and Drop instance will be graded only in the case if
there is a maximum of two levels of targets. The first level are the "base" targets.
They are attached to the base image. The second level are the targets defined on
draggables.
2.) Another limitation is that the target bounds are not checked against
other targets.
For now, it is the responsibility of the person who is constructing the course
material to make sure that there is no overlapping of targets. It is also preferable
that targets on draggables are smaller than the actual parent draggable. Technically
this is not necessary, but from the usability perspective it is desirable.
3.) You can have targets on draggables only in the case when there are base targets
defined (base targets are attached to the base image).
If you do not have base targets, then you can only have a single level of nesting
(draggables on the base image). In this case the client side will be reporting (x,y)
positions of each draggables on the base image.
Correct answer format
---------------------
(NOTE: For specifying answers for targets on draggables please see next section.)
There are two correct answer formats: short and long
If short from correct answer is mapping of 'draggable_id' to 'target_id'::
correct_answer = {'grass': [[300, 200], 200], 'ant': [[500, 0], 200]}
correct_answer = {'name4': 't1', '7': 't2'}
In long form correct answer is list of dicts. Every dict has 3 keys:
draggables, targets and rule. For example::
correct_answer = [
{
'draggables': ['7', '8'],
'targets': ['t5_c', 't6_c'],
'rule': 'anyof'
},
{
'draggables': ['1', '2'],
'targets': ['t2_h', 't3_h', 't4_h', 't7_h', 't8_h', 't10_h'],
'rule': 'anyof'
}]
Draggables is list of draggables id. Target is list of targets id, draggables
must be dragged to with considering rule. Rule is string.
Draggables in dicts inside correct_answer list must not intersect!!!
Wrong (for draggable id 7)::
correct_answer = [
{
'draggables': ['7', '8'],
'targets': ['t5_c', 't6_c'],
'rule': 'anyof'
},
{
'draggables': ['7', '2'],
'targets': ['t2_h', 't3_h', 't4_h', 't7_h', 't8_h', 't10_h'],
'rule': 'anyof'
}]
Rules are: exact, anyof, unordered_equal, anyof+number, unordered_equal+number
.. such long lines are needed for sphinx to display lists correctly
- Exact rule means that targets for draggable id's in user_answer are the same that targets from correct answer. For example, for draggables 7 and 8 user must drag 7 to target1 and 8 to target2 if correct_answer is::
correct_answer = [
{
'draggables': ['7', '8'],
'targets': ['tartget1', 'target2'],
'rule': 'exact'
}]
- unordered_equal rule allows draggables be dragged to targets unordered. If one want to allow for student to drag 7 to target1 or target2 and 8 to target2 or target 1 and 7 and 8 must be in different targets, then correct answer must be::
correct_answer = [
{
'draggables': ['7', '8'],
'targets': ['tartget1', 'target2'],
'rule': 'unordered_equal'
}]
- Anyof rule allows draggables to be dragged to any of targets. If one want to allow for student to drag 7 and 8 to target1 or target2, which means that if 7 is on target1 and 8 is on target1 or 7 on target2 and 8 on target2 or 7 on target1 and 8 on target2. Any of theese are correct which anyof rule::
correct_answer = [
{
'draggables': ['7', '8'],
'targets': ['tartget1', 'target2'],
'rule': 'anyof'
}]
- If you have can_reuse true, then you, for example, have draggables a,b,c and 10 targets. These will allow you to drag 4 'a' draggables to ['target1', 'target4', 'target7', 'target10'] , you do not need to write 'a' four times. Also this will allow you to drag 'b' draggable to target2 or target5 for target5 and target2 etc..::
correct_answer = [
{
'draggables': ['a'],
'targets': ['target1', 'target4', 'target7', 'target10'],
'rule': 'unordered_equal'
},
{
'draggables': ['b'],
'targets': ['target2', 'target5', 'target8'],
'rule': 'anyof'
},
{
'draggables': ['c'],
'targets': ['target3', 'target6', 'target9'],
'rule': 'unordered_equal'
}]
- And sometimes you want to allow drag only two 'b' draggables, in these case you should use 'anyof+number' of 'unordered_equal+number' rule::
correct_answer = [
{
'draggables': ['a', 'a', 'a'],
'targets': ['target1', 'target4', 'target7'],
'rule': 'unordered_equal+number'
},
{
'draggables': ['b', 'b'],
'targets': ['target2', 'target5', 'target8'],
'rule': 'anyof+number'
},
{
'draggables': ['c'],
'targets': ['target3', 'target6', 'target9'],
'rule': 'unordered_equal'
}]
In case if we have no multiple draggables per targets (one_per_target="true"),
for same number of draggables, anyof is equal to unordered_equal
If we have can_reuse=true, than one must use only long form of correct answer.
Answer format for targets on draggables
---------------------------------------
As with the cases described above, an answer must provide precise positioning for
each draggable (on which targets it must reside). In the case when a draggable must
be placed on a target that itself is on a draggable, then the answer must contain
the chain of target-draggable-target. It is best to understand this on an example.
Suppose we have three draggables - 'up', 's', and 'p'. Draggables 's', and 'p' have targets
on themselves. More specifically, 'p' has three targets - '1', '2', and '3'. The first
requirement is that 's', and 'p' are positioned on specific targets on the base image.
The second requirement is that draggable 'up' is positioned on specific targets of
draggable 'p'. Below is an excerpt from a problem.::
<draggable id="up" icon="/static/images/images_list/lcao-mo/up.png" can_reuse="true" />
<draggable id="s" icon="/static/images/images_list/lcao-mo/orbital_single.png" label="s orbital" can_reuse="true" >
<target id="1" x="0" y="0" w="32" h="32"/>
</draggable>
<draggable id="p" icon="/static/images/images_list/lcao-mo/orbital_triple.png" can_reuse="true" label="p orbital" >
<target id="1" x="0" y="0" w="32" h="32"/>
<target id="2" x="34" y="0" w="32" h="32"/>
<target id="3" x="68" y="0" w="32" h="32"/>
</draggable>
...
correct_answer = [
{
'draggables': ['p'],
'targets': ['p-left-target', 'p-right-target'],
'rule': 'unordered_equal'
},
{
'draggables': ['s'],
'targets': ['s-left-target', 's-right-target'],
'rule': 'unordered_equal'
},
{
'draggables': ['up'],
'targets': ['p-left-target[p][1]', 'p-left-target[p][2]', 'p-right-target[p][2]', 'p-right-target[p][3]',],
'rule': 'unordered_equal'
}
]
Note that it is a requirement to specify rules for all draggables, even if some draggable gets included
in more than one chain.
Grading logic
-------------
1. User answer (that comes from browser) and correct answer (from xml) are parsed to the same format::
group_id: group_draggables, group_targets, group_rule
Group_id is ordinal number, for every dict in correct answer incremental
group_id is assigned: 0, 1, 2, ...
Draggables from user answer are added to same group_id where identical draggables
from correct answer are, for example::
If correct_draggables[group_0] = [t1, t2] then
user_draggables[group_0] are all draggables t1 and t2 from user answer:
[t1] or [t1, t2] or [t1, t2, t2] etc..
2. For every group from user answer, for that group draggables, if 'number' is in group rule, set() is applied,
if 'number' is not in rule, set is not applied::
set() : [t1, t2, t3, t3] -> [t1, t2, ,t3]
For every group, at this step, draggables lists are equal.
3. For every group, lists of targets are compared using rule for that group.
Set and '+number' cases
.......................
Set() and '+number' are needed only for case of reusable draggables,
for other cases there are no equal draggables in list, so set() does nothing.
.. such long lines needed for sphinx to display nicely
* Usage of set() operation allows easily create rule for case of "any number of same draggable can be dragged to some targets"::
{
'draggables': ['draggable_1'],
'targets': ['target3', 'target6', 'target9'],
'rule': 'anyof'
}
* 'number' rule is used for the case of reusable draggables, when one want to fix number of draggable to drag. In this example only two instances of draggables_1 are allowed to be dragged::
{
'draggables': ['draggable_1', 'draggable_1'],
'targets': ['target3', 'target6', 'target9'],
'rule': 'anyof+number'
}
* Note, that in using rule 'exact', one does not need 'number', because you can't recognize from user interface which reusable draggable is on which target. Absurd example::
{
'draggables': ['draggable_1', 'draggable_1', 'draggable_2'],
'targets': ['target3', 'target6', 'target9'],
'rule': 'exact'
}
Correct handling of this example is to create different rules for draggable_1 and
draggable_2
* For 'unordered_equal' (or 'exact' too) we don't need 'number' if you have only same draggable in group, as targets length will provide constraint for the number of draggables::
{
'draggables': ['draggable_1'],
'targets': ['target3', 'target6', 'target9'],
'rule': 'unordered_equal'
}
This means that only three draggaggables 'draggable_1' can be dragged.
* But if you have more that one different reusable draggable in list, you may use 'number' rule::
{
'draggables': ['draggable_1', 'draggable_1', 'draggable_2'],
'targets': ['target3', 'target6', 'target9'],
'rule': 'unordered_equal+number'
}
If not use number, draggables list will be setted to ['draggable_1', 'draggable_2']

Course Grading
##############
This document is written to help professors understand how a final grade for a
course is computed.
Course grading is the process of taking all of the problems scores for a student
in a course and generating a final score (and corresponding letter grade). This
grading process can be split into two phases - totaling sections and section
weighting.
*****************
Totaling sections
*****************
The process of totaling sections is to get a percentage score (between 0.0 and
1.0) for every section in the course. A section is any module that is a direct
child of a chapter. For example, psets, labs, and sequences are all common
sections. Only the *percentage* on the section will be available to compute the
final grade, *not* the final number of points earned / possible.
.. important::
For a section to be included in the final grade, the policies file must set
`graded = True` for the section.
For each section, the grading function retrieves all problems within the
section. The section percentage is computed as (total points earned) / (total
points possible).
******************
Weighting Problems
******************
In some cases, one might want to give weights to problems within a section. For
example, a final exam might contain four questions each worth 1 point by default.
This means each question would by default have the same weight. If one wanted
the first problem to be worth 50% of the final exam, the policy file could specify
weights of 30, 10, 10, and 10 to the four problems, respectively.
Note that the default weight of a problem **is not 1**. The default weight of a
problem is the module's `max_grade`.
If weighting is set, each problem is worth the number of points assigned, regardless of the number of responses it contains.
Consider a Homework section that contains two problems.
.. code-block:: xml
<problem display_name=”Problem 1”>
<numericalresponse> ... </numericalreponse>
</problem>
.. code-block:: xml
<problem display_name=”Problem 2”>
<numericalresponse> ... </numericalreponse>
<numericalresponse> ... </numericalreponse>
<numericalresponse> ... </numericalreponse>
</problem>
Without weighting, Problem 1 is worth 25% of the assignment, and Problem 2 is worth 75% of the assignment.
Weighting for the problems can be set in the policy.json file.
.. code-block:: json
"problem/problem1": {
"weight": 2
},
"problem/problem2": {
"weight": 2
},
With the above weighting, Problems 1 and 2 are each worth 50% of the assignment.
Please note: When problems have weight, the point value is automatically included in the display name *except* when `"weight": 1`. When the weight is 1, no visual change occurs in the display name, leaving the point value open to interpretation to the student.
******************
Weighting Sections
******************
Once each section has a percentage score, we must total those sections into a
final grade. Of course, not every section has equal weight in the final grade.
The policies for weighting sections into a final grade are specified in the
grading_policy.json file.
The `grading_policy.json` file specifies several sub-graders that are each given
a weight and factored into the final grade. There are currently two types of
sub-graders, section format graders and single section graders.
We will use this simple example of a grader with one section format grader and
one single section grader.
.. code-block:: json
"GRADER" : [
{
"type" : "Homework",
"min_count" : 12,
"drop_count" : 2,
"short_label" : "HW",
"weight" : 0.4
},
{
"type" : "Final",
"name" : "Final Exam",
"short_label" : "Final",
"weight" : 0.6
}
]
Section Format Graders
======================
A section format grader grades a set of sections with the same format, as
defined in the course policy file. To make a vertical named Homework1 be graded
by the Homework section format grader, the following definition would be in the
course policy file.
.. code-block:: json
"vertical/Homework1": {
"display_name": "Homework 1",
"graded": true,
"format": "Homework"
},
In the example above, the section format grader declares that it will expect to
find at least 12 sections with the format "Homework". It will drop the lowest 2.
All of the homework assignments will have equal weight, relative to each other
(except, of course, for the assignments that are dropped).
This format supports forecasting the number of homework assignments. For
example, if the course only has 3 homeworks written, but the section format
grader has been told to expect 12, the missing 9 will have an assumed 0% and
will still show up in the grade breakdown.
A section format grader will also show the average of that section in the grade
breakdown (shown on the Progress page, gradebook, etc.).
Single Section Graders
======================
A single section grader grades exactly that - a single section. If a section
is found with a matching format and display name then the score of that section
is used. If not, a score of 0% is assumed.
Combining sub-graders
=====================
The final grade is computed by taking the score and weight of each sub grader.
In the above example, homework will be 40% of the final grade. The final exam
will be 60% of the final grade.
**************************
Displaying the final grade
**************************
The final grade is then rounded up to the nearest percentage point. This is so
the system can consistently display a percentage without worrying whether the
displayed percentage has been rounded up or down (potentially misleading the
student). The formula for the rounding is::
rounded_percent = round(computed_percent * 100 + 0.05) / 100
The grading policy file also specifies the cutoffs for the grade levels. A
grade is either A, B, or C. If the student does not reach the cutoff threshold
for a C grade then the student has not earned a grade and will not be eligible
for a certificate. Letter grades are only awarded to students who have
completed the course. There is no notion of a failing letter grade.
