Switching to natural weighting

Background

If a course uses a weighted aggregation scheme, switching to Natural aggregation will likely result in undesired outcomes that are the result of a known bug. Specifically, your weights will all be adjusted to a sum of 100, and items or categories that used a weighted aggregation scheme in the original course will be marked as extra credit. As a result, it may be easier to recreate the gradebook from scratch, though it is possible to “fix” the outcome by following the steps below:

How-To

  1. Before you begin, be sure to record your item and category weights. You can find them in the gradebook’s Setup tab or menu link in the “Weights” column.
  2. From the Setup tab, click the “Edit” drop-down in the “Actions” column for the topmost row (the category for the entire course) and then click Edit settings.
  3. In the “Grade category” section, click the Show more… link.
  4. Change the “Aggregation” drop-down to Natural and click [Save changes]. All weights will be reset to zero and any value previously controlled by a different weighted aggregation will be marked as extra credit (as evidenced by the + sign next to their max grade).
  5. Click the “Edit” drop-down in the “Actions” column for any item or category marked as extra credit and then click Edit settings.
  6. In the “Parent category” section, click the Show more… link.
  7. Uncheck the Extra credit checkbox and then click [Save changes]. Repeat this process for any additional items or categories marked as extra credit.
  8. From the Setup tab, check the box in the “Weights” column for any item or category you want to be weighted.
  9. Fill out the “Weights” fields with the weights you recorded originally and click [Save changes].
