Say you wish to be taught French. Would you do higher in the event you studied for 100 hours in a year-long course (~2 hours per week) or if these hours had been compressed right into a month (~20 hours per week)?
Surprisingly, the reply appears to be that extra intensive language teaching programs do higher! This seems to be a reasonably constant analysis discovering, within the dozen or so research the place the comparability has been made. From a paper by Raquel Serrano and Carmen Muñoz:
[We] analyze the efficiency of grownup college students enrolled in three various kinds of EFL applications by which the distribution of time varies. The primary one, referred to as ‘intensive’, distributes a complete of 110 h in 7 months … ‘semi-intensive’, which gives the identical variety of hours distributed in 3–4 months … intensive course gives 110 h in 5 weeks … The outcomes from our analyses counsel that concentrating the hours of English instruction in shorter durations of time is extra helpful for the scholars’ studying than distributing them in lots of months.
The analysis is stunning as a result of the spacing effect is one in all psychology’s most robustly replicated results. Basically, when materials is introduced repeatedly, unfold out over time, it leads to enhanced reminiscence in comparison with repeated displays briefly succession.
What’s Happening Right here?
After I stumbled into this analysis a pair weeks in the past, it shocked me! If any analysis outcome felt stable, it was the spacing impact. Whereas the spacing impact and the seeming superiority of intensive language instruction will not be essentially incompatible, they’re positively in pressure.

Listed below are some speculative explanations for what is perhaps happening:
1. Spacing makes studying more durable, generally too arduous.
Spacing is likely one of the “desirable difficulties” that will increase efficacy at the price of short-term efficiency difficulties. Nonetheless, added complexity can generally flip the anticipated profit of those fascinating difficulties.
Contextual interference, as an example, tends to be useful, however it may well backfire for complicated expertise or poorer students. Equally, retrieval practice tends to be useful—except the particular person can’t retrieve what they’re attempting to recollect. These outcomes counsel that the optimum learning approach for complicated expertise modifications over time, beginning with massed/blocked/evaluation, and shifting to spaced/interleaved/retrieved presentation.
On condition that most individuals in language lessons don’t go away with conversational fluency, it could be that the complexity of language studying interferes with the anticipated advantages of spacing.
2. Spacing of particular person gadgets is impartial of total classroom intensiveness.
A number one clarification for the spacing impact (though hardly the one one) is that spacing works as a result of massed apply leads to poor processing of repeated info. Once you see the identical vocabulary phrase a number of occasions in a row, you cease being attentive to it. In distinction, when the identical phrase comes up at spaced-out intervals, you attend to it recent every time since you possibly can’t simply recollect it from reminiscence.
It’s attainable that within the time frames studied, particular person gadgets of vocabulary and grammar are being spaced out simply positive within the intensive applications, so the effectivity positive aspects of the intensive schedule will not be noticed.
3. Intensive lessons are extra motivating (or appeal to extra motivated college students)
Maybe the outcomes aren’t cognitive in any respect—it’d merely be {that a} extra intensive class is extra pleasing, motivating, or leads to a greater classroom expertise. Serrano and Muñoz cite one study that evaluated qualitative efficiency from intensive/intensive learning schedules and located the intensive lecture rooms had higher group cohesion and motivation. (Then once more, this outcome would additionally make sense if the scholars had been studying higher.)
In arguing for my intensive language immersion bursts, I equally relied on a non-cognitive argument. I’ve discovered that the behavior of talking a specific language shortly turns into entrenched when assembly new individuals, which is usually the case when touring overseas. Since English is widespread, there’s a bent to default to talking English even in the event you examine sufficient to converse within the new language. This motivated the “no English” rule that Vat and I employed while traveling.
4. Maybe the assessments weren’t delayed sufficient.
Alternatively, maybe this analysis is only a pink herring. Possibly the intensive teams would carry out higher if the comparability of the intensive/intensive coaching was 5 years out. A widely known consequence of the spacing impact is that massed displays are typically simpler initially, however their benefit usually fades over time.
Nonetheless, on condition that we frequently enroll in a French or Spanish class aiming to have the ability to have conversations now, reasonably than mildly higher non-conversational capability in half a decade, these analysis outcomes can’t be ignored.
Rethinking Spacing?
As somebody who has made a present of taking up big, intensive projects, I’ve typically been a minimum of mildly embarrassed by the dissonance between the timeframe of these tasks and my repetition of the standard recommendation to area out learning to carry out higher.
However maybe there’s much less pressure than I initially thought. It seems that research of precise classroom language studying appear to weigh extra in favor of the strategy I’ve intuitively most popular—working via an intensive burst to get to semi-conversational after which following that with periodic evaluation, reasonably than learning in twenty-minute day by day periods from the get-go.
Fairly than over-adjust my present recommendation, two issues appear to carry:
- Spacing for particular person gadgets remains to be central. Issues like flashcards with spaced opinions, applications like Pimsleur or DuoLingo that encourage evaluation of earlier models, and even revisiting previous classroom workouts are doubtless helpful. Spacing must be utilized inside a learning program, even when the recommendation for the general depth of the schedule is much less clear.
- Intensive tasks must be adopted by extra leisurely upkeep. Even when an intensive burst can get you shortly to proficiency, it in all probability is smart to proceed to apply at a extra leisurely tempo for months or years after in the event you don’t need that proficiency to say no too abruptly.
Studying this analysis has made me curious in regards to the results of intensive versus prolonged curricula for different topics. Do these in programming bootcamps overlook greater than their faculty counterparts who unfold CS lessons over 4 years? Is an government MBA worse for administration considering than one taken over a pair years? I don’t have any solutions, however I’m curious in mild of this sudden analysis.
