This video requires my students to conduct learner material interactions, as well as learner and learner interaction. Students can directly get to know a learning point through a video clip. The principle message it aims to deliver is to stimulate a natural interest through the materials, so that helps the instructor achieve the final goal of education. Since the target students in our group are K-12 level children, we need to use multifunctional materials to draw their attention to focus on. This video does not include any inherent interactions forcing them to give feedback in any aspect. However, it sets a good example regarding the topic “introducing yourself in English in front of people”, which could drive the students to practice according to the video and practice with their classmates in groups. Besides, students could take notes when watching this video, and discuss, imitate the video in groups. As instructors, we can design a small quiz regarding the information in the video, and conduct a competition in these groups. One important factor in cooperative learning design is student-student interactions. Video material is a kind of multimedia teaching method which has many advantages. Multimedia teaching can motivate children to learn actively. For children, interest is the best teacher and the driving force for learning. Multimedia technology, through realistic and creative pictures, combined with rich dynamic effects, turns passive remembering and listening into active watching” and “thinking, which stimulates students’ strong interest in learning and is also in line with children’s cognitive characteristics. It is easy for k-12 students to be distracted when listening to lectures in the classroom. The flexible use of multimedia in teaching can prompt the child’s unintentional attention to quickly turn into intentional attention. Teachers use the characteristics of rich multimedia, sound, and picture, and combination of dynamic and static to create the situation required for teaching, which can make students emotionally infected and emotionally resonate, increase the attention of pupils, and make them actively participate in learning Come here. A student can comprehend the content through the screen, develop associations, and develop thinking. In the teaching process, the use of multimedia means is conducive to deepening the understanding of knowledge and enhancing students’ memory. For example, it is difficult for young age kids to recite English essays or dialogues. At this time, teachers can use multimedia courseware to display the characters in the dialogue and give some hints to deepen the students’ understanding of the content and cause students to associate, so as to achieve the memory of recitation, like the video I provided.
