- Grading types
### Grading types

# Grading types

The teacher can choose from nine

**Grading types**the one that best matches the educational goals and allows the best assessment of the students.The nine grading types are:

- All or nothing
- Absolute position
- Relative to correct position
- Relative to the next item (excluding last)
- Relative to the next item (including last)
- Relative to both the previous and next items
- Relative to ALL the previous and next items
- Longest ordered subset
- Longest contiguous subset

- All or nothing
The grading type is selected in the question's settings:

The following examples illustrate how each grading type works. The question is to place the six letters A, B, C, D, E and F in alphabetical order. It is marked out of 6.

## All of nothing

If all items are in the correct position, then full marks are awarded. Otherwise, the score is zero.

^{Source: Help in the question settings}With the

**All or nothing**grading type, only the answer A, B, C, D, E, F in the correct alphabetical order gets a total grade of 100%. All other answers score 0%.### Example

Use the

**All or nothing**grading type.#### Explanation

All six items A, B, C, D, E and F are correctly placed, so the grade is 100%.

### Example

Use the

**All or nothing**grading type.#### Explanation

Items E and F are placed incorrectly, so the grade is 0%.

## Absolute position

An item is considered correct if it is in the same position as in the correct answer. The highest possible score for the question is

*the same as*the number of items displayed to the student.^{Source: Help in the question settings}With the

**Absolute position**grading type, each draggable item placed in its correct position gets a score of 100%. Items placed in incorrect positions get a score of 0%.### Example

Use the

**Absolute position**grading type.#### Explanation

Items A, B, D and E are placed correctly, so each one gets a score of 100%. Items C and F are placed incorrectly, so they get a score of 0%.

## Relative to correct position

An item is considered correct if it is in the same position as in the correct answer. Correct items receive a score equal to the number of items displayed minus one. Incorrect items receive a score equal to the number of items displayed minus one and minus the distance of the item from its correct position. Thus, if

*n*items are displayed to the student, the number of marks available for each item is , and the highest mark available for the question is , which is the same as .^{Source: Help in the question settings}With the

**Relative to correct position**grading type, each draggable item placed in its correct position gets a score of 100%. When an item is not placed in its correct position, its score decreases linearly with distance from its correct position (down to 0% for the first and last elements).Let

*n*be the number of draggable items displayed to the student and*x*the number of positions away from the correct position. The score for an item placed*x*postions away from its correct position is given by:For example, suppose there are 6 draggable items (). If an item is placed 3 positions from its correct position (), its score is equal to:

If there are 10 draggable items () and if an item is placed 2 positions from its correct position (), its score is equal to:

### Example

Use the

**Relative to correct position**grading type.#### Explanation

There are 6 draggable items ().

Item F is 5 positions away from its correct position (). Therefore its score is equal to:

Item A is 1 position away from its correct position (). Therefore its score is equal to:

And similarly for the other items.

## Relative to the next item (excluding last)

An item is considered correct if it is followed by the same item as it is in the correct answer. The item in the last position is not checked. Thus, the highest possible score for the question is

*one less than*the number of items displayed to the student.^{Source: Help in the question settings}With the

**Relative to the next item (excluding last)**grading type, draggable items correctly followed by the next item get a score of 100%. Otherwise, they get a score of 0%. The last draggable item is not counted.### Example

Use the

**Relative to the next item (excluding last)**grading type.#### Explanation

- Item C is correctly followed by item D, so it gets a score of 100%.
- Item D is not followed by item E, so it gets a score of 0%.
- Item A is not followed by item B, so it gets a score of 0%.
- Item E is correctly followed by item F, so it gets a score of 100%.
- F is the last draggable item. It has no score and is not counted in the total grade.
- Item B is not followed by item C, so it gets a score of 0%.

## Relative to the next item (including last)

An item is considered correct if it is followed by the same item as it is in the correct answer. This includes the last item which must have no item following it. Thus, the highest possible score for the question is

*the same as*the number of items displayed to the student.^{Source: Help in the question settings}The

**Relative to the next item (including last)**grading type is identical to the**Relative to the next item (excluding last)**grading type except that the last draggable item is counted. This item gets a score of 100% if it is placed correctly in the last position, otherwise it gets a score of 0%.### Example

Use the

**Relative to the next item (including last)**grading type.#### Explanation

This example is identical to the previous one, except that the last draggable item is counted.

- The last draggable item, F, is not placed in the last position, so it gets a score of 0%.

## Relative to both the previous and next items

An item is considered correct if both the previous and next items are the same as they are in the correct answer. The first item should have no previous item, and the last item should have no next item. Thus, there are two possible points for each item, and the highest possible score for the question is

*twice*the number of items displayed to the student.^{Source: Help in the question settings}With the

**Relative to both the previous and next items**grading type, items placed correctly relative to both the previous and next items get a score of 100%, items placed correctly relative to either the previous or next item get a score of 50% and items not placed correctly relative to either the previous or next item get a score of 0%.### Example

Use the

**Relative to both the previous and next items**grading type.#### Explanation

- Item A, the first draggable item, is correctly placed in the first position and followed by Item B, so it gets a score of 100%.
- Item B is correctly preceded by item A and followed by item C, so it gets a score of 100%.
- Item C is correctly preceded by item B but it is not followed by item D, so it gets a score of 50%.
- Item E is correctly followed by item F but it not preceded by item D, so it gets a score of 50%.
- Item F, the last draggable item, is correctly preceded by item E but it is not placed in the last position, so it gets a score of 50%.
- Item D is neither preceded by item C nor followed by item E, so it gets a score of 0%.

## Relative to ALL the previous and next items

An item is considered correct if it is preceded by all the same items as it is in the correct answer, and it is followed by all the same items as it is in the correct answer. The order of the previous items does not matter, and nor does the order of the following items. Thus, if

*n*items are displayed to the student, the number of marks available for each item is , and the highest mark available for the question is , which is the same as .^{Source: Help in the question settings}Each draggable item gets a score based on the total number of items that precede the item and that follow it. Let

*n*be the number of items displayed to the student and*x*the number of items placed before a given item plus the number of items placed after this item. The score for the given item is equal to:The highest score for the question is 100% when all items are in the correct order. The lowest score is 0% when all items are in reverse order.

For example, suppose there are 6 draggable items (). If an item is preceded by 1 previous item and followed by 2 next items (), its score is equal to:

If there are 10 draggable items () and if an item is preceded by 4 previous item and followed by 2 next items (), its score is equal to:

### Example

Use the

**Relative to ALL the previous and next items**grading type.#### Explanation

There are 6 draggable items displayed to the student ().

Item F is not preceded by any previous item, so it gets a score of 0%.

Item A is followed by 4 next items (B, C, D, E), so it gets a score of:

Item D is preceded by 1 previous item (A) and followed by 1 next items (E), so it gets a score of:

And similarly for the other items.

## Longest ordered subset

The grade is the number of items in the longest ordered subset of items. The highest possible grade is the same as the number of items displayed. A subset must have at least two items. Subsets do not need to start at the first item (but they can) and they do not need to be contiguous (but they can be). Where there are multiple subsets of equal length, items in the subset that is found first, when searching from left to right, will be displayed as correct. Other items will be marked as incorrect.

^{Source: Help in the question settings}## Longest contiguous subset

The grade is the number of items in the longest contiguous subset of items. The highest possible grade is the same as the number of items displayed. A subset must have at least two items. Subsets do not need to start at the first item (but they can) and they MUST BE CONTIGUOUS. Where there are multiple subsets of equal length, items in the subset that is found first, when searching from left to right, will be displayed as correct. Other items will be marked as incorrect.

^{Source: Help in the question settings}With the

**Longest contiguous subset**grading type, the longest subset in the response is identified, whose items are contiguous in the set of draggable items. The items of the subset get a score of 100%, the other items a score of 0%.In the answer, it is not necessary for the subset items to begin with the first draggable item and they need not be placed next to each other.

### Example

Consider the following question with ten draggable items: A, B, C, D, E, F, G, H, I, J in this order. Use the

**Longest contiguous subset**grading type.#### Explanation

In the answer, there are three subsets whose items are contiguous in the set of draggable items:

- D, E, F, G
- H, I, J
- A, B, C

The longest subset is D, E, F, G with four items. Each of these items gets a score of 100%, the other items a score of 0%.
