There was a facet I omitted from my earlier put up, Space invaders, wherein I coated the spacing impact as a method of maximising long-term retention.
Zsolt Olah picked it: interleaving and – sarcastically! – I judged it a bridge too far to incorporate in the identical put up and so determined to separate it out throughout a second one.
You’ll see why…
Interleaving
Earlier than defining interleaving, I really feel it’s useful to evaluate the other: blocked presentation or blocking. This method is equal to massed presentation whereby the content material is consumed successively:
An alternate method is to separate every block into leaves and differ their presentation. This method is named interleaved presentation or assorted presentation or combined presentation:
The illustration above maintains the topical sequence, in distinction to random interleaved presentation whereby the sequence is shuffled:
Spaced interleaving
Simply as the spacing effect may be employed to supply spaced block presentation:
…so can also or not it’s employed to supply spaced interleaved presentation (grouped):
…or spaced random interleaved presentation (grouped):
I take advantage of the qualifier “grouped” as a result of, whereas that’s the normal approach of illustrating interleaving – I think because of the formal paradigm of schooling by which you replenish the durations assigned to you – I see no purpose why every leaf couldn’t be separated over time; therefore spaced interleaved presentation (separated):
…and spaced random interleaved presentation (separated):
As you may see, it will get difficult actual fast, and that’s earlier than using reinforcement or the testing effect!
Dynamic interleaving
Once I have a look at the assorted permutations of spacing and interleaving, I ponder if an optimum timing or sequencing regime exists. Full disclosure: I’ve carried out zero analysis to seek out out; you probably have, I’d like to play my lazy internet card and ask you to share your findings by way of a remark beneath.
I additionally surprise in regards to the efficacy of a bespoke regime that sequences the leaves in keeping with a dynamic sample – take a look at newest > take a look at earlier > current new – resulting in a last summative take a look at:
I name this regime spaced dynamic interleaved retrieval (fairly a mouthful!) or dynamic interleaving for brief. Once more, when you’re conscious of something on the market that’s comparable, please let me know.
