This is a very simple site for learning basic words in English. http://www.dicts.info/vocabulary-trainer.php?l1=english&l2=turkish&disa=0
There are twenty sets of words that appear with a picture and the English word (which is also heard as a spoken word), and then the student has a multiple choice test to identify the correct translation. Works in a number of languages, Turkish being one.
Not very extensive, and only deals with direct translations, but lower level students might find this motivating.
One could also ask students to report back on words that they have learned, and perhaps ask them to write complete sentences to move them beyond the direct translation state.
