How To: Study Item weighting feature
From it's first days, Scriptorian has utilized a "weighting" scheme to
determine when a study item should be presented for review. This
weighting approach helped ensure that study list material was
presented in a manner that would aid in memory retention. The 3.0
version of Scriptorian includes a modification in the algorithm that
improves this spaced repetition feature.
Every study item in a study list is assigned two weight values. This
value is a combination of time and proficiency. One value is for Quote
It, the other for Chase. Each time you use Quote It or Chase for a
study item, the weight value will be adjusted. All new items have the
maximum weight value attached to them. Recently completed study items
that have not required assistance to complete will have the lowest
weight associated with them. When you run Quote It or Chase for a
study list, those items with the largest weight value will be
presented first- these being the ones that usually require the most
assistance or have not been reviewed for the longest period of time
(or a combination of both factors). You can check out the Scriptorian
help topic Weighting of study list items for a good example of how
this works.
As mentioned above, the weight value is derived from factors of
elapsed time and proficiency. Normally these are considered equally
important, however you can alter this if you like. In either the
Options or Study List Options dialogs, you can adjust how these
factors influence the weight calculation. Adjustments can be made for
Quote It and Chase independent of each other.
The Study List window displays the weighting information for each
study item in the list, as well as help and elapsed time information.
This information is a good way to see which items will be next up for
review (you can sort on each of the columns by clicking on the column
header)
Because the weight information is stored in the study list, if you
have more than one person using a particular study list, then the
weight information will not be effective. In this case, it is best to
make a copy of the study list for each person that will use it. This
way, each person's progress can be effectively tracked.
