I’m studying my Japanese video and audio lessons on a spaced repetition schedule, which is very different than a normal study schedule.
Most schools and curricula are basically like this:
Unit 1
Lesson 1
Lesson 2
Lesson 3
Unit 1 (Lesson 1-3 Review)
Unit 2
Lesson 4
Lesson 5
Lesson 6
Unit 2 Review (Lessons 4-6 Review)
I’ve taught at schools before with textbooks like these and have used textbooks like these before, and the best ones use information from previous lessons and build on top of each other so that you are reviewing what you already learned while at the same time learning new information.
At worst, the lessons are completely disjointed and do not have any kind of logical ordering, structuring or progression.
(I would say that most English textbooks in Korea are like this.)
So what I’m doing is actually something like this:
Day 1: Lesson 1
Day 2: Lesson 1 (review), 2
Day 3: 2, 3,
Day 4: 1, 3, 4
Day 5: 2, 4, 5
Basically, I’m not only reviewing the immediate past lessons, but I’m also reviewing lessons that I studied a long time ago.
For example, my future plan might look like this:
Day 30: 1, 9, 17, 24, 26, 28, 30
The lessons all before 30 would be kind of like skimming reviews, not as intense as the initial first lesson, but would still be good to keep the information in my mind.
