How I Use It
I would use the Phrasal Verb Machine with the whole class to introduce specific verbal phrases, particularly to illustrate the differences between phrases with a common verb (make out vs. make up). This would be followed up with whole group and partner practice to reinforce the phrase. After reviewing all 100 phrasal verbs, I would then have whole class practice with the "exercise," turning it into a game.
In addition to whole class teaching and review, I would also use the app as a center to give students who are struggling with phrasal verbs another opportunity for practice.
This is a simple app, and on it's own won't get students to mastery of phrasal verbs. For one thing, it only has 100 phrasal verbs, and in English there are thousands. That said, the phrasal verbs included, are definitely high utility. Also, some of the animations vary in terms of how clear they express the meaning of the phrasal verbs. All in all the app is entertaining, easy to use, and has the added bonus of providing examples of the phrasal verb being used in English sentences and translated into six other languages (Spanish, French, Portuguese, Russian, Italian, and German).
