How much language input you could be getting

How much input can you get?

I ran some numbers…

Average conversation speed is, apparently 140-160 words a minute. We can understand speeech much faster, but we don’t like to produce speech much faster. Let’s be conservative though, and say that we are gettin 100 words a minute of input in listening to audio / in a live class (I’d love to see actual data, but I don’t have it. Do you?)

For good CI reading, we want learners reading somwhere between 150-250 words a minute. Much below this and it’s likely an indicator that they are not processing it well enough – it’s shifting from extensive reading to intensive.

Now, let’s make two assumptions: one that our classes and materials only manage to stay in target language 95% of the time, and that the comprehensibility level remain a nice, high 95% (but not an ideal 98%).

So, on my numbers, an hour of oral class is 100 wpm * 60 mins = 6000 * 0.98 * 0.95 = 5415 words an hour.
Similarly, a lower end 150 wpm reading is 8122.5 words and hour.

A 14 week semester, 10 hours with 3 live instruction, 3 audio practice, 4 reading, would be 64980 a week, 909720 words of input a semester.

A school class doing 2 hours a week, 38 weeks a year, with 2 hours outside class reading: 974700.

A 3hrs a week reading habit, 48 weeks a year: 1169640.

All of these numbers are, I would suggest, orders of magnitude higher than the amount of text a student normally receives in a standard course. Even if you halved them, it’s still a lot of input. It would, undoubtedly, require the availability of a suitably vast amount of appropriately graded material. Difficult for Latin, almost impossibly for Greek.

Still, any shift in this direction would be good.

So, what to do? If you’re the learner in this equation, my advice is to read everything easy that you can lay hands on. Read all the text in every intro course you can borrow. For Latin, download every direct method reader you can, but every novella your budget stretches to, and develop a podcast habit. For Greek, hmmm, I’m still trying to solve this conundrum. Apart from textbooks, even most easy material is not as easy as it needs to be. This remains a problem to be solved. In the meantime, for Greek, Latin, or whatever it is you love, re-read everything as well: x2, x3, x10!
