Points
5.1 To demonstrate, we will use the
following example and calculate the grade using each method. Let’s say our fictitious course has two
grading categories (activity types).
Labs & Tests. Our fictitious
student, John, has achieved the following grades:
Points
Labs: 20/30, 60/100
Tests: 80/100, 15/20
Using the points system, John’s grade would be calculated:
(20+60+80+15) / (30+100+100+20)
=175/250
=70.0%
This feature can be turned on by
going to the CLASS screen and setting the “Activity Type Weighting” to “Use
Points” for each category (activity type) you have listed.
Weighted Categories
5.2 Weighted categories require that
each category (activity type) must have an associated weighting. This weighting is often expressed as a percentage
although 1st Class GradeBook will allow you to use any weighting
scheme you like. In our example, let’s
say that Tests are weighted at 60% and Labs are weighted at 40%. Here is how John’s grade would be calculated
with this grading scheme:
((20+60) / (30+100) * 40) + ((80+15) /
(100+20) *60)
=((80/130) *
40) + ((95/120) * 60)
=(0.6154% *
40) + (0.7917 *60)
=24.62 + 47.50
