Rosetta Stone for Mac

From Ben Stitz:

By recording which words you are getting wrong and reviewing those words more frequently, the program adapts your program of study to your individual needs. Contrast this to the standard method of learning using lists of words on paper - the words you already know get the same attention as words you don't. Words can be reviewed from English to Hebrew or Hebrew to English, and reviewed in random order so you are not remembering them from their position in the list. Statistics are provided and allow you to set personal goals for each session. By allowing you to filter on the frequency a word occurs in a typical Hebrew text, the program allows you to better target a vocabulary appropriate to your level of knowledge - be that beginner or advanced. In any language, some words are more common than others. For example, "the" occurs more than "zoo" in a standard English text. Typically, if a student knows the top 200 most often used words, they can recognise over 50% of what they are reading. By filtering on the word frequency, you can learn the more common words before the least common, again making your study more efficient.
