用图片教学怎么说英语

Using images to teach is often referred to as "visual learning" or "visual instruction." You could say something like: "I'm using visual learning techniques to teach this lesson, using images to help illustrate the concepts."
Alternatively, you could say: "I'm using pictures to teach this lesson. I find that using visual aids helps students understand and retain the material more effectively."
Overall, the term "visual learning" is a broad term that refers to the use of visual aids, such as images, diagrams, charts, and videos, to help convey information and facilitate understanding. Visual aids can be an effective way to supplement traditional teaching methods, as they can help make abstract concepts more concrete and easier to understand.
