Let’s move around to learn a language in a faster way! Language classes of the future might come with some physical exercises. It is found that people learn a new language more easily when words are combined with the relative movements. And people learn a new tongue more quickly when words are accompanied by movements.
Researchers enrolled 20 volunteers in a six-day course to learn a language designed to explain the study results in an easy way. Half of the teaching materials were taught by using spoken and written instructions and exercises, while the other half was taught with body movements to combine each word. In the teaching process, the learners will be asked to act out. For instance, in teaching "cut" to the learners, the trainer did the movement in cutting things into several pieces, and then the learners followed him and memorized it by doing the gesture. It was resulted that the learners remembered more of the words with movements and used them more readily when creating new sentences. The researchers explained that the acting of the words helped the learners’ memory by creating a more complex representation of the words and this could leave a deep impression of the words on learners’ mind. One of the researchers claimed that the method could really speed up foreign language learning in the real language classes of schools.
