According to the video, a webinar on how to write an ESA lesson plan, by Carl, a TEFL teacher trainer, ESA lesson plans consist of three stages: Engage, Study, and Activate.
The Engage stage involves getting the students talking and thinking about the topic of the lesson. This can be done through games, stories, pictures, or discussion questions. The goal is to get the students emotionally involved in the topic.
In the Study stage, the teacher introduces the target language or skills of the lesson. This can be done through grammar explanations, vocabulary presentations, or listening activities. The students then practice using the language through activities such as gap fills, pronunciation drills, or group work.
In the Activate stage, the students use the language they have learned in a communicative way. This can be done through role plays, discussions, stories, or letter writing. The teacher checks for accuracy and corrects any errors.
The speaker also mentions that there are different ways to order the stages of an ESA lesson plan. A boomerang ESA lesson plan, for example, starts with Engage, then Activity, then Study, and then back to Activate. The speaker says that this is a good way to check for errors before the students have been taught the target language.
