How I Use It
As the teacher, I create the Quizlet sets and share the URLs with my students. This way I know that the information they are going to study is correct. Many of the activities have an embed code, so the students can practice within the course management system.
As a Spanish teacher, an advantage to Quizlet is the ability to set language and have the vocabulary words pronounced for the students. They are able to see and hear the Spanish vocabulary.
The students can create free accounts using an email address. Once they have an account, they can join a teacher established class. This will give them easy access to all the teacher sets. The students like the competition. If they have an account, it keeps track of scores and ranks them. To increase the competitive spirit, I play my own sets and set the bar high (but achievable) for the students to strive for.
I agree with other reviews - the quality of study and review is dependent on the quality of the information in the sets. Quizlet is the obvious match for studying vocabulary. With some creativity cards can be created for other topics: historical figures, math problems with answers, geographical locations with pictures.
The Learn mode is effective in helping students keep track of how many answers they know. It saves the incorrect answers so they can be reviewed a second time.
