Four apps for students to learn English

Quizlet

Quizlet is a learning app---a computer program you use on your mobile device. It can help users build and test

their knowledge of English words and terms. Quizlet has word sets for millions of subjects. And, it is quickly becoming a useful mobile tool for language learners.

Socrative

In Socrative, teachers can create timed learning games. In class, students compete individually or as part of a team against classmates. One game students love is called space Race. In this game, if a team answers a question correctly, their rocket moves forward. This team whose rocket gets to the end first wins. Also, teachers can use Socrative as an “exit ticket,” a question they can ask students about what they learned in that day’s class. Students write their answers on their mobile devices. Then, the teacher can show the answers on a shared video screen.

QR Codes

A QR Code is a kind of sign that a smartphone can read with its camera. When your phone camera reads a QR code, it takes you to a website, image, video or anything you want to share. For example, one will take you to the VOA Learning English website.

Evernote

Evernote lets users store and share notes, images and recordings in one place. Teachers can also use Evernote to give homework.
