The Center for Teaching & Learning of Chung-Ang University offers a variety of extracurricular programs as online courses. The courses, which run until July 31, are open to any CAU student. To take a course, a student must log in to canvas.cau.ac.kr and click on the COOC. Then there is a button applying for extracurricular courses. Once a student has applied, the way to take a course is the same as regular classes through e-class. There are also benefits. A certificate of completion will be issued if the enrollment rate of 80 percent or more is achieved. In addition, the student will be registered as a complete person in the Rainbow system. The online classes being offered include courses on the basics and utilization of PowerPoint, Excel, Word, and Illustrator CC. These are the tools that students often use in life. There are classes on data management and visualization using Excel and Power BI to keep up with the trend. The courses also include lectures on interesting subjects such as design thinking and independent publishing. Are you spending repeated daily life in the same space as lethargy? Taking the extracurricular program would be a good choice to use time productively.
