📚 Wide Applicability
Spaced repetition is a method that can be applied to nearly every subject requiring memorization, such as language, science, history, mathematics, and even technical concepts.
🧠 Declarative Knowledge
It is particularly suited for declarative knowledge—facts, definitions, and discrete concepts. Every fact can be transformed into a little, easily retrievable unit (like a flashcard).
⚡ Procedural Skills
Besides, spaced repetition is capable of facilitating the learning of procedural skills( math, coding...) but only when active practice and repetition of procedures are performed alongside.
🔁 Long-Term Mastery
The use of spaced repetition over a period of months or years not only allows for the learning of various topics to be accumulated but also helps one retain knowledge beyond examinations thus, making it suitable for lifelong learning.
💡 Adaptation Needed
Even though it is a method that is applicable to many areas, there are still some subjects that may need more creative card design or integration with other techniques. Concepts that are abstract or highly interlinked may require not only explanation but also SRS.
✅ Key Takeaway
Spaced repetition is beneficial for almost all subjects if the learning objectives are clear, the materials are divided into smallest units, and active recall is applied regularly.
