Lessons are in increasing difficulty according to JLPT levels and school grade indicated in [KANJIDIC2](http://www.edrdg.org/wiki/index.php/KANJIDIC_Project) (the JLPT levels used are the old levels N4-N1 and not the new levels, see [this document](https://jlpt.jp/e/reference/pdf/guide2011_e_02.pdf) for correspondence). Example sentences are sourced from the [Tanaka corpus](http://www.edrdg.org/wiki/index.php/Tanaka_Corpus). +## Why this method? + +I'm putting this section first to make it visible, but you might want to skim +[how to use Datagengo](#how_to_use_datagengo) first. + +I had previous experience with learning kanji using books, starting with +Heisig's *Remembering the Kanji* (RTK), and spaced repetition systems (SRS) +such as Anki or WaniKani. I started with RTK, which I think was truly usefull +to me as it gave me a sense of how kanji are constructed and therefore how to +apprehend them, but I never completed the book. I went on and started using an +Anki deck that contained all the RTK kanji, which I didn't use for very long. A +bit later I started WaniKani and went through a bunch of that, but I still +stopped at some point, partly by lack of motivation and partly by frustration +that this was going nowhere. + +Here are my main frustrations with SRS methods: + + +- The methods I used were based on individual kanji or word, and did not + provide real-world context in which those kanji or words might be used. + +- Items (kanji or words) are taken in isolation and not grouped by level or by + lesson, which means that the full effort of memorization has to be made for + each item independently. + +- As a consequence of the lack of context and logical grouping, I found it very + easy to confuse different kanji or different words. + +- I was always doubtful of "spaced repetition with increasing intervals", it + feels way less efficient to me than consistently repeating something for some + time and then assuming that it is definitively learnt. In my head, "assuming + something is learnt", after having spent a definite amount of effort on it and + having decided it was over with, helps create a category of things I'm supposed to + know, which in turn helps cement that knowledge. + +During my multi-year break from Japanese (something like 2016-2023), I pondered +this question occasionally and started thinking about a new method, that +eventually became Datagengo. + +The basic idea behind Datagengo is to add as much context (explicit or implicit) with the +learning of each kanji, so that all of these contextual clues can be used +when recalling them. + +Here is what Datagengo does, and why I expect it to work much better, at least for me: + +- Datagengo exploits the Tanaka corpus to provide in-context example sentences + for all of the learnt kanji. + +- Datagengo tries to help you learn all the kanji using as few example + sentences as possible, to be efficient. + +- Datagengo requires the learner to write by hand, which is in my experience the + best way to learn difficult things. + +- Lessons, or "batches", are logical units that somewhat "work together" (even + if the sentences or kanji have nothing to do with one another), helping to cement + that entire unit of knowledge in one go instead of lots of independent + efforts on tiny things. + +- Once a lesson has been studied around a dozen times, it becomes very easy to + recite, and it is therefore natural to declare it as "acquired knowledge". + Even if you forget the details of the individual sentences, memory of the + kanji will stay, embedded within the context of the lesson and therefore + easier to pick up when called upon. + +- The period at which you were studying each kanji also becomes part of its + learning context, making it again easier to recall. If like me you + have a visual understanding of the passage of time (I personally see the + year as a big loop, with months of the year each having a relatively + precise position on it), then this effect can be even stronger. + + ## How to use Datagengo ### How to study a lesson -**High-level overview:** +#### High-level overview 1.
