On the dual-channel principle of information processing from Teacher Li's "colored chalk"

In Applying Learning Science to Improve Learning Strategies, Meyer summed up three principles of learning science, and the third one mentioned the multimedia principle. This third article is also an important theoretical basis for multimedia teaching. The effect of enhancing memory mentioned that image stimulation is higher than voice stimulation. In the process of classroom teaching, adding multimedia materials such as pictures will greatly improve the efficiency of learners' memory.

The study of this knowledge suddenly reminds me of my chemistry teacher in junior high school and the small box of colored chalk that Miss Li carries with her in every class. At that time, without multimedia and modern information technology, it was not easy to find some colored chalk.

When Mr. Li always explains some important places in class, he takes out his precious colored chalk from his small box of colored chalk and draws a few strokes in that important place. These places marked with colored chalk look particularly conspicuous, just like a painting. Of course, the effect of our study is also very good. Every time we test difficult points, we can always play back the main points of colored chalk painting in our minds.

Isn't this just the image stimulation, which improves our memory efficiency at once, makes us master the important and difficult points of chemistry well, and makes the exam not difficult, so the results are naturally excellent.

There is so much energy hidden in this small colored chalk, and the source of this energy, after so many years, I found his theoretical basis.

Miss Li, in that simple teaching environment, knows such skills. Now I will study this knowledge hard and apply it to teaching to improve the teaching effect better.
