For groups or classes that wish to practice spoken English, role-playing exercises can give the opportunity to push their understanding of language to the next level. Role-play is probably best for more advanced students who can already communicate in English but works well for teaching some of the subtleties of the English language, such how to use tone of voice and inflection. Play guessing games, such as those based on "20 Questions," with groups of four, and keep them simple by the teacher giving out a short list of items to be guessed before the activity starts.
Learning to speak in English requires confidence as well as a basic understanding of grammar and vocabulary. Find the confidence to practice and overcome a fear of making mistakes and looking or feeling foolish with online learning sites. As well as basic lessons in how to use English, spoken exercises give examples by a native speaker. Hearing how the words are spoken and then practicing in private give the confidence to practice with others.
Team activities with an element of competition put energy and motivation into the classroom. Games such as Chinese Whispers sometimes produce humorous results when the whispered word gets distorted as it travels along the line. For this type of activity to work, the students need to feel safe and secure in their ability to speak. Establish ground rules beforehand regarding casting blame on the student who speaks the given word at the end of the line.
There comes a time when formal English classes are not enough for the student of spoken English. English-speaking clubs, or conversation groups, introduce you to like-minded people who are also trying to improve their spoken English. Online clubs and groups give a level of anonymity for those who are still building their confidence, while in face-to-face groups, there is chance to make real friends and share interests. A tip if joining a conversation group is to find friends who share your interests. That way you can practice talking in English about something you both find meaningful.
