Open classes are usually free courses, which can be watched in official website or other cooperative platforms. These courses cover a wide range of subjects and are usually taught by some well-known experts or teachers. Because the open class is free, it can attract a large number of students to watch, which is also a remarkable feature of the open class. In the open class, students can listen to experts' explanations, understand the frontier trends of the subject, and communicate with teachers and other students through interactive links. However, there are usually not too many personalized teaching in open classes, because there are too many students, and it is impossible for teachers to give detailed guidance for each student. Because open classes are free, sometimes there may be some technical problems or the quality of the courses is not high enough.
In contrast, online classroom is a more formal and systematic way of online learning. Online courses usually require students to pay a certain fee to participate, and there will be a relatively complete and systematic curriculum system. In the online classroom, students can get a more comprehensive and in-depth learning experience, including more detailed explanations of knowledge points, more examples and case studies, and more interactive and communication links. Online classroom can also provide some additional learning resources and services, such as online answering questions and downloading learning materials, which can help students better master knowledge and skills. Because online classes need to be paid, there are usually some quality assurance and technical support to ensure that students can get a more stable and efficient learning experience.
Based on my personal experience, I think that open courses and online courses have their own advantages and disadvantages. Open classes can let me know some new knowledge points and subject trends, and also communicate with other students through interactive sessions to expand my social circle. However, due to the lack of personalized teaching in open classes, sometimes I feel that my learning effect is not ideal. The online course pays more attention to systematicness and depth, which allows me to master knowledge and skills more comprehensively and get more learning resources and services. But online classes also need to pay a certain fee, which may sometimes make me feel a little burdened.
I think both open classes and online classes are very valuable online learning methods. They have their own advantages and disadvantages, and they can be chosen according to their own needs and actual conditions. If you want to know some new knowledge points and subject dynamics, you can participate in some open classes; If you want to master knowledge and skills more systematically, you can choose some online courses to study. Of course, the best way is to combine them and make full use of their respective advantages to gain a more comprehensive and in-depth learning experience.
