This is timely. I'm about 4 weeks into a "let's learn Korean" self-study program. The last time I seriously tried to learn a foreign language was Spanish in high school and it was quite a debacle. But after many years married to a Korean woman, I finally decided I was embarrassed enough not knowing more than a few utility words in Korean to take the plunge.
I remember looking into learning Korean about 6 or 7 years ago and there really weren't many on-line self-study resources and very few classes I could take. This time I found an virtual explosion of resources, free text books, skype practice sessions, listening guides, vocabulary resources, etc. For more popular languages, like French, the number of resources is almost mindboggling.
I've decided to focus the beginning of my studies on raw vocabulary acquisition and I've settled on using Anki to do this. My friends know that I have a pretty bad memory, so I've been shocked and surprised at how well Anki has worked. In 4 weeks I've managed to memorize (to different degrees of recall) about 300 words (out of a list of the 1000 most common).
Last week I sat down to start my grammar lessons with a free university textbook and was even more shocked and surprised at how much of the text I was able to decode. I wouldn't call it comprehension exactly, but maybe 20-40% of the beginner-level sentences I could read well enough to get the gist without knowing any grammar. I checked ahead into later chapters and was amazed that I was still able to work out some non-negligible percent of most of the lessons.
For practice I watched a couple Korean tv shows (they love to put subtitles under everything which is helpful) and was also surprised that I could work out some bits of the nightly news. Not enough to really know what was going on, but within a month going from knowing basic foods and the word "bathroom" to starting some minimal comprehension felt pretty remarkable.
More recently I've been practicing language production and took the attitude the article advocates -- just focus on getting the point across, don't worry about all the grammar bits. So, when something my wife and I are doing involves some vocabulary I remember, I try to formulate a basic sentence around it. I know I'm missing some things, but I told my wife to just grade me on "is it understandable or not?" not on "is it correct or not?". It's eased up the pressure quite a bit.
More importantly, even if my little experiment fails in the end. Outside of language study, I feel much more..."engaged" all the time. Like my brain is turned up a little. I'm finding my memory is definitely improving and some mental tasks that were starting to become harder as I've aged have started to become easier.
It's actually kind of cool.
