Subset learning

Frequently, you may want to review a portion of your collection. For example, in order to refresh memory before a specific exam, or to review the material pertaining to a topic of current interest. In such circumstances, use subset learning to learn or review a portion of material which may be outstanding or not.

In the simplest case of subset learning, the button Learn at the bottom of the contents window can be used to execute outstanding repetitions on a selected branch of the knowledge tree. For example, to make repetitions in the Medical Sciences branch, click that branch and then click Learn. Using Learn in the contents window is like using Learn in the element window, except only elements belonging to the selected branch will be considered in making repetitions.

Here are the three main ways of subset learning:

You can choose any of these options on the Process branch : Learning submenu of the contents menu, or Process browser : Learning submenu of the browser menu. This will result in learning or review of material in the currently selected branch of the contents window or in the current browser subset.

The parameter Subset in the statistics window indicates the progress of repetitions in subset learning. This field displays the number of items, the number of topics and the number of pending elements in subset learning. The name in the parentheses describes the currently processed subset.

Example 1

If you would like to review the material related to Auguste Comte (1798-1857) do as follows:

  1. Press Ctrl+F and paste Auguste Comte in the search box
  2. Press Enter or click Find (this will search your collection and open a browser with the results)
  3. Choose one of the subset learning options:
    • to prevent forgetting: press Ctrl+Alt+L or choose Process browser : Learning : Learn to review only the outstanding material. This will help you review only the items that are most likely to be forgotten and a portion of topics that have been scheduled for review for today
    • to learn new things: choose Process browser : Learning : Review topics to review all topics related to Auguste Comte
    • to maximize the review: choose Process browser : Learning : Review all to review all topics and to force a repetition on all items related to Auguste Comte

Example 2

If your history exam is approaching and you cannot cope with all repetitions in the collection, make sure that at least your daily portion of history is thoroughly reviewed:

  1. Select History in the contents window
  2. Click Learn at the bottom of the contents window

Repeat the procedure daily. However, in the last 3-5 days, you could follow that yet with Process branch : Learning : Review all to protectively refresh the material that would optimally be scheduled after the exam. Important! This strategy is not recommended for long-term learning! It departs from the optimum timing of review to consolidate memories. It should only be reserved for situation when burning school situation forces you to neglect your long-term planning.

You can also choose Learning : Learn branch on the element menu to begin branch learning for one of the ancestors of the currently displayed element (Ctrl+Alt+L). You can use this method if you encounter interesting material that you would like to refresh more thoroughly before you proceed with your standard learning process.

If you have final drill enabled, remember that subset learning does not keep a separate final drill queue and elements that score less than Good (4) are put to the global final drill queue.
