Quizlet.com is a great website for effectively learning vocabulary, for languages and anything else! For a quick video on how the whole thing works, check out the demo video. Cool fact: It was started by a 15-year-old high school student!
Basically, you can add and share vocabulary lists, make them public, private or share only with certain groups. Once you have them in the system (or you find an existing set you want to study), you can choose between several options for learning/familiarizing and self-assessment.
The site is slick, fast and has lots of active users. It's really a cool place to learn anything from the Greek Alphabet to TOEFL and SAT vocabulary and plenty more.
There are already gobs of lists available on the site - so many that individual attention is being brought to amazing collections available on the site, such as the HSK Test Vocabulary Preparation Pack and more.
So take a look at Quizlet when you get the chance. It's likely that content already exists for what you need to study! I have added this to all the language sections even though there are not vocabulary stacks yet for all of these. Reason being you can use the site to create any vocabulary lists you want - it's wide open!
The Quizlet Story
For lack of a professional writer working for Quizlet, here are some ramblings from me, Andrew Sutherland, creator of Quizlet, president of Brainflare, web developer, and high school student.
Quizlet is how I occupy my free time and even some of my non-free time. My mission for Quizlet is to make learning vocabulary not a chore. I know a lot of teachers assign vocabulary to students, but few students actually "absorb" words into their vocabularies after they take their test. Which kind of defeats the purpose, right? So Quizlet is my response - it aims to make learning fun, thus make learning effective. At the very least, it can help students do better on quizzes and tests even if they don't fully "absorb" their words.
I started Quizlet in October 2005, back when I was a mere 15-year-old (human years). I had just received a list of 111 French Animals to memorize from my magnanimous French teacher. I was puttering along with my dad with some call-and-response type quizzing. "Man, I love doing this" was NOT what I was thinking. So I put my thinking cap on, and the first line of code for Quizlet was written that night. Of course, that code was all deleted when I thought about what Quizlet would be. You really should plan first.
Quizlet is a shoestring operation. For its first 420 days, it was the work of only myself. I did all the designing, programming, debugging, and perfecting. The project had no product managers, no marketers, and no venture capitalists. It was just me and my testers. Recently I've realized some things are out of my field of expertise (I'm not a lawyer, for example). So there are a few other people involved these days.
Quizlet is free and will remain free to all users. The current plan is to offer targeted advertising on the non-studying pages. I'm hoping to make some deals with some educational and test-prep companies and perhaps some universities. If you're interested in advertising to my userbase of highly-motivated high-school and college students, shoot me a note (see above right).
Let's see, what haven't I covered? Ahh, the name Quizlet comes from Quizlette, the name of the "little" quizzes my French teacher gives. She could have charged royalties, but that just wouldn't be right…
And because you really want to know, I made Quizlet using only the finest ingredients:
