Question:
In your materials you write that users should avoid memorizing
sets (e.g. countries of Europe) or long sequences (e.g. the
alphabet). What if I want to remember the sequence of a form of
Tai Chi?
Answer:
Let us consider an example in which you want to memorize the
entire sequence of letters in the alphabet. It won't be very
effective if you use the following item:
Q: What is the sequence of
letters in the alphabet?
A: A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z
You will notice that you frequently stumble on parts of the sequence and need to stop repetitions just to exercise the entire sequence in the traditional way (like we all learn poems by rote).
However, you can approach this in a way that guarantees quick effects:
Q: What is the sequence of
letters in the alphabet between A and E?
A: A,B,C,D,E
Q: What is the sequence of
letters in the alphabet between D and H?
A: D,E,F,G,H
Q: What is the sequence of
letters in the alphabet between G and K?
A: G,H,I,J,K
etc. etc.
After 2-3 weeks of repetitions, you may take on an extra task of recalling the whole sequence after each repetition of these simplified items. This will make sure you can recite the entire alphabet quickly. You will also frequently rehearse that parts of the sequence that are harder for your memory (e.g. V,W,X,Y,Z) as opposed to those that are much simpler (e.g. A,B,C,D,E)

Item reviewed:
Q: a
rod-and-tube element temperature sensor consists of:
A: a high expansion metal tube containing a low expansion rod.
The rod & tube are attached on one end. The tube changes
length with changes in temperature, causing the free end of the
rod to move
Suggestions:
This is a typical case of combining a number of items in one with detriment to the ability to recall the combined item. The suggestion here is to split the item into a number of simpler items that reproduce the same information in student's memory:
Q: What are
the two parts of a rod-and-tube temperature sensor?
A: rod and tube
Q: What is the
expandability of the tube in rod-and-tube sensor?
A: high
Q: What is the
expandability of the rod in rod-and-tube sensor?
A: low
Q: How is
temperature indicated in the rod-and-tube sensor?
A: tube moves relative to the rod
Q: Where are rod and tube connected?
etc. etc.

Cloze deletions (i.e. questions with blanks) are generally a good learning tool; however, in most cases it is better to keep a single deletion per question
(Jim Ivy, USA, June 4, 1997)
Question:
What is the difference between a topic
and an item?
Answer:
Topics are used to present knowledge (like chapters in a book),
while items are used to test knowledge by means of repetitions (e.g. they have the question-and-answer
structure). The main difference is that topics do not take part
in repetitions but are only presented before learning a sequence
of items. This helps to approach the subject as a whole before
repetitions begin. See also: Topics vs. items
(Deron Isaac, USA, May 21, 1997)
Question:
How can I edit texts of items during repetitions without backing out of the test mode?
Answer:
Choose Q to edit the question, A to edit the
answer, or E to edit all text components. You can also edit all properties of all
components by using pop-up menus available
with right button click on a component in question.
Question:
What is the purpose of the option Tools : Categories?
Answer:
SuperMemo 98 introduces the concept of a category to help you keep items related to
different subjects in different branches of the knowledge
tree (contents window). It also makes it possible to give
different item groups different appearance (e.g. size of
text components, screen layout, font, color, and many
more). Read more: Using categories

Question:
I am using Advanced
English to enhance my
English and business English. Now I am registering for CFA examination
(that is Chartered Financial Analyst program of Association of
Investment Management and Research). There are several
organizations developing and distributing methodological stuff
for preparing to the exam. A lot of things should be memorized
for passing the exam. What do you think the best way to fit
SuperMemo for memorization and what approach should I use to
prepare my own knowledge base for memorizing the material. Is
special programming knowledge needed for it?
Answer:
No specialist knowledge is needed to prepare simple knowledge
systems in SuperMemo. With Ctrl+A (i.e. Add new
item) you get 90%
of functionality! All advanced editing options can be worked
around by an appropriate questions-and-answer approach. Perhaps
it would be useful yet to learn how to add images to your items
(see help for details). To learn more about effectively
structuring knowledge in SuperMemo you might want to read Knowledge Structuring and Representation; however, nothing works better as learning
on one's own mistakes in formulating knowledge for learning with
SuperMemo
(David Mckenzie, New Zealand, Apr 8, 1998)
Question:
Is there any point in keeping collections separate?
Answer:
No. Once you master contents categories and templates, there is no
point. You gain global search, global registries, global
repetitions, global optimization, etc. This would not be
advisable back in SuperMemo 7 as item difficulty measure
(E-factor) was dependent on the average difficulty of items in the collection. Presently, the item difficulty
measure (A-Factor, or absolute difficulty factor) is absolute and
does not depend on the context in which an item is placed (see: Algorithm SM-8). Only
the length of the first interval will significantly be affected
by the average difficulty of items in the collection. However,
this shall not bear dramatically on the speed of
learning. Especially that variable forgetting index for individual items makes it possible to set
different first intervals for whole contents categories or branches of the knowledge tree
Question:
What should I use Duplicate for? What for do I need
the same item in the same collection?
Answer:
You can duplicate an item, if you
want to add to the another item which is only slightly different.
This way you can spare some time by reediting the old item
instead of typing in the new one
