"Future illiterates will no longer be people unable to read or write but people who do not understand images." In order to survive in the future society led by images, one must learn all the techniques of image reading, image understanding, and visual thinking. Micro-credit courses offer a variety of multielement and flexible course contents. The micro-credit course "Visual Reading Ability" hopes to help students not only master a specialized skill but be able to have a foothold on a profession and combine other fields. With the main direction "cultivating visual reading/application ability," the course enhances students' image reading ability and expressive ability. In the practice lessons, it also trains their information application and digitalization abilities as well as strengthens their workplace ability. The assessment materials and related questionnaires will be used after class to examine the implementation effectiveness of this course, which serves as a method of improving the course in the future.
