iMendi, a simple language learning service that I reviewed in January, recently added support for a few more languages. iMendi now offers language learning exercises in Italian, German and French. To use iMendi just select the language you speak and select the language you want to learn. iMendi then gives you the choice of choosing a lesson (level 1, level 2, etc) or trying a randomly chosen lesson.
Applications for Education
Because it doesn't provide any direct instruction, iMendi's best purpose is as a place where students can practice vocabulary words and terms. The site is straight-forward enough that even young (elementary school age) students could use the site on their own.
