Since I’ve touched on this in another topic, I thought I’d get into detail about it. I’ve been a bit frustrated that it is hard to quantify the progress you make reading native material. You know it gets easier, but it’s a gradual process, so there’s no immediate gratification. I’m very fond of numbers and statistics, so I tried to measure my own progress.
So this is what I did:
- over the course of 1 month, I read 114 Japanese newspaper articles on NHK’s website (more like 20 days, though, since I had to stop for 9 days in between because of a study trip that left me with little spare time)
- I tried to cover many different topics, but of course was a bit biased in my selection (didn’t read more than a couple of sports-themed articles)
- I created a spreadsheet and wrote down (a) the length of each article and (b) the number of words I had to look up
- (I looked up all words I didn’t know with certainty, including the reading, but didn’t count names of places and people. When I was in doubt, but turned out to be correct, I also didn’t count that.)
- I then calculated the ratio of unknown words to measure the change.
- I also re-read most of the articles directly afterwards and counted again (that wasn’t the main purpose, though)
- I did not do any kind of conscious repeating apart from reading the articles.
Here are the results:
Important is the blue stuff here (red is only for 2nd time reading which I recorded more out of curiosity). The horizontal axis show the progress on # of articles, the % numbers on the vertical axis show the percentage of words* I had to look up.
The diagonal blue line shows the trend. As you can see, there are always spikes (often during articles on topics I was unfamiliar with, like politic organs or technology) and lows (I became quite good at reading articles about weather, climate and natural disasters). What’s important, however, is that there was a constant and notable trend downwards, from about 2,4% to 1,2%. So basically I was able to eliminate half of the unknown words in the course of one month or 114 articles.
(*Actually, this is not entirely true: I calculated the value by dividing the # of lookups by the # of characters of the article without taking into account how long the words I looked up were, so the actual percentage should be higher. It just would’ve taken a lot of extra effort otherwise. But what’s important here is the progress, not the exact values.)
To illustrate that further, let’s take a look at these numbers:
The table shows (a) the average percentage of lookups in the last 7 days and (b) the total average percentage of lookups of all days. Here, too, you can see both numbers going down steadily.
Conclusion: One month is not a long time, so I was very happy to see that progress was constant and significant. I’m no one special, I don’t think I’m above-average at memorizing stuff, so I think the results can be applied to most everyone.
It is easy to loose motivation if you can’t see or feel your immediate progress, so I hope the results of my little self-experiment will encourage others and reaffirm them that progress is constant and significant if you keep doing something regularly.
