<P ALIGN=CENTER><B>Assignment Elements</B></P>

<P>For ease of grading, a Workshop Assignment should have a reasonable 
	number of &quot;Assessment Elements&quot;. Each element should cover
	a particular aspect of the assignment. Typically an assignment will have
	something between 5 to 15 elements for comments and grading, the 
	actual number depending on the size and complexity of the assignment. A peer 
	assignment with only one element is allowed and has a similar assessment
	strategy to the standard Moodle Assignment. 
	
<P>The type of elements dependent of the assignment's grading strategy.

<P><B>Not Graded.</B> The elements are descriptions of aspects of the assignment. 
	The assessor is asked to comment on each of these aspects. As with all the grading
	strategies, there is also an area for general comments.


<P><B>Accumulative Grading.</B> The elements have the following three features:
<OL>
<LI>The DESCRIPTION of the assessment element. This should clearly state what 
	aspect of the assignment is being assessed. If the assessment is qualatative
	it is helpful to give details of what is considered excellent, average 
	and poor.
	
<LI>The SCALE of the assessment element. There are a number of prefined
	scales. These range from simple Yes/No scales, through multipoint scales to
	a full percentage scale. Each element has its own scale which should be choosen
	to fit the number of possible variations for that element. Note that the scale 
	does NOT determine the element's	importance when calculating the overall 
	grade, a two point scale has the same &quot;influence&quot; as a 100 point 
	scale if the respective elements have the same weight...

<LI>The WEIGHT of the assessment element. By default the elements are given the same 
	importance when calculating the overall grade of the assignment. This can be
	changed by giving the more importance elements a weight greater than one, and
	the less important elements a weight below one. Changing the weights does NOT 
	effect the maximum grade, that value is fixed by the Maximum Grade parameter
	of the peer assignment. Weights can be assigned negative values, this is an 
	experimental feature.
</OL>
<P><B>Error Banded Grading.</B> The elements will normally describe certain items 
	or aspects which must be present in the assignment. The assessment is made on the
	present or absence of these items or aspects. The teacher must all set of grade table which 
	give the suggested grades when all the items are present, when one is absent, when two are
	absent, etc. If certain items are more important than others then those items can be given
	a weighting greater than one. Minor items can be given a weighting less than one. The
	overall &quot;error count&quot; is a weighted sum of the missing items. The assessor 
	can always make a minor adjustment to these suggested grades.

<P><B>Criterion Grading.</B> The elements will give a set of &quot;level&quot; statements
which can be used to rank the assignment. The statements may be cumulative or they may 
each be self contained. The assessor must decide which statement best fits each piece of
work. The teacher must also relate each criterion statement with a suggested grade. These
should normally be in order. The assessor can make a minor adjustment to these 
suggested grades.</P>

<P><B>Rubric Grading.</B> This is similar to Criterion Grading but there is more than
one criteria. The number of criteria is given in the assignment parameters. Within each
criterion there can be up to five &quot;level&quot; statements. In a given assignment
the number of levels can vary from criterion to criterion. When setting up a criterion a
blank level statement signals the end of the level statements. Thus some criteria may have
two levels, others have three, up to five levels. The criteria can be weighted. The levels
are scored 0, 1, 2, up to 4. The grade for the assessment is a weighted sum of these
scores.
