Word cards

http://visualidioms.blogspot.com/

Encourage your students to use word cards when learning new words from the posts (and there are plenty!). Word cards are better than word lists because you can change the order of the words which you want to learn and revise. Thus you avoid the primacy and recency effect, i. e. the words at the top and the bottom of the list are better remembered than those in the middle. See an online tool for creating word cards http://quizlet.com/

Another web-based tool for making flashcards is Cram (http://www.cram.com/) Flashcards are effective because they are based on the principles of rote and memorization. You can make your own idiom flashcards (two-sided or three-sided) by copying and pasting the content of the blog http://visualidioms.blogspot.com/ (you can even add the images). Then you can share, export or print the cards. Encourage your students to make their own sets and/or help you to make the cards - thus they will retain more of the information they are studying.
