"Correct use of deck" is the suggestion of Anki deck function in Anki official manual, and the contents are as follows:
From the above, the official suggestion is not to create many small categories of cards, but to use several large categories of cards for research. Obsessive-compulsive disorder patients can use labels or fields to finely classify content, instead of creating many small groups of classification cards.
The "valid" cards in Anki are all internalized into the brain memory, so there is no need to classify the cards. Organize the contents of the cards in an easy-to-remember way. After memorizing them in the brain, the high-end sorting opportunities in the brain will automatically sort them.
The biggest drawback of over-classification is that it destroys the effectiveness of the "interval repeat algorithm" because different types of cards have different memory difficulties. After manual classification, you often inadvertently choose a card with easy memory, instead of relying on the "interval repeat algorithm" to automatically select the card that needs to be reviewed for you at present.
Therefore, please put all the "valid" cards that need to be memorized into the "00- All" deck. If you can't help yourself to classify, then ask yourself, "Classification is usually to distinguish the importance. Since there are less important cards, you can file/delete them directly. Why should we classify them? "
The organization of Anki card content is the difficulty in using Anki. The content of the card cannot be reached in one step, and it usually needs to be revised repeatedly. If it is difficult to recall the card when looking at it many times, there may be two main reasons:
The solution of 1 point varies from person to person. After all, Anki is just a memory tool. How to learn and understand new knowledge systematically is beyond Anki's scope. In this regard, you can turn to related books that explain learning methods.
The second question. At present, I haven't found a monograph on "interval repetition" learning theory. Only Anki fans in Zhihu's and SuperMemo's blogs have some sporadic articles. In terms of card content organization, I recommend reading a blog post by SuperMemo, Effective Learning: 20 Principles of Organizing Knowledge [English] [Chinese]. The core idea expressed in this article is that cards can't pile up a lot of contents in cards, and it is not feasible to expect to remember them once in a while. The content of the card should follow the principle of minimum information, and a card only remembers an extremely simple knowledge point.
According to my understanding, whether it is a question-and-answer form or a fill-in-the-blank form, it is best for a card to recall the answer quickly within 5 seconds, and stimulate the corresponding brain circuits quickly, frequently and accurately to form a long-term memory. There is no strong correlation between this question and the answer. If you can't think of the answer for a long time, or the answer is a few hundred words, and so on. , are you can't remember the unqualified cards. You need to transfer them to the "0 1- iteration" booth for optimization and splitting, and then return to the "00- all" booth for memory.
Making cards is not easy, and it takes a lot of time and energy. Sometimes when I see an expired and useless card, I can't bear to delete it, so this deck exists. Because all the cards stored in this deck are "discarded" cards, the number of new cards and review cards in this deck is set to "0" to avoid digital reminder interference.
Anki is good, but don't mess around. It is meaningless to spend too much time on the structure of cards, but it is really meaningful for Anki to study the content organization of cards.
