One possible stimulus for teaching the present perfect tense could be a short video clip or a series of images depicting various life experiences. The video or images could show different scenarios such as traveling to different countries, trying new foods, meeting new people, achieving personal goals, or experiencing significant life events.
After watching the video or looking at the images, the teacher can ask the students to discuss and share their own experiences related to the scenes shown. The students can take turns describing what they have done or experienced in their lives using the present perfect tense.
For example, if the video shows a person skydiving, the teacher can ask the students, “Have you ever gone skydiving?” The students can respond using the present perfect tense, such as “Yes, I have gone skydiving once” or “No, I have never gone skydiving.”
This stimulus encourages students to practice using the present perfect tense to talk about their personal experiences and helps them understand the concept of using this tense to describe actions or events that happened at an unspecified time in the past or have a connection to the present.
