The Hazards of Online Classes

With the continuous development of science and technology, online courses are gradually welcomed by the public. However, compared with the traditional offline courses, there are some disadvantages, such as the lack of students' learning conditions, the lack of interaction in the classroom, and the difficulty in testing the teaching effect.

First of all, the conditions and environments for students to participate in online courses are not guaranteed. Especially in rural areas, due to the poor network and the low level of family economy, students can not participate in the live broadcast of the course on time, which affects the progress of learning. In addition, some parents work and play at home will also produce noise, interfering with children's learning.

Secondly, the teaching method of network course is single and lack of emotional interaction. From the current situation of network teaching in colleges, many teachers are not fully prepared before class, only the mechanical setting of check-in, reading textbooks and PPT. In addition, due to the limitations of electronic equipment, even if the camera is turned on, teachers and students still can not achieve effective emotional communication, students become passive recipients of classroom content, greatly reducing their autonomy.

Finally, it is difficult to test the learning effect of online courses.

Some teachers do not force students to turn on the camera in class, which provides them with the opportunity to distract. They can browse micro-blog or play games at the same time, ignoring the content of the class. In the exam, students can get high scores by cheating, without being detected by electronic devices. In addition, because students' learning effect can not be truly and accurately fed back to teachers, it will also affect teachers' follow-up teaching activities.

Only when students, teachers, parents and social forces work together, can we overcome these problems and promote the development and progress of online education.

随着科学技术的不断发展，网络课程逐渐受到大众的欢迎。然而，与传统的线下课程相比，存在一些不足之处，如学生学习条件不足、课堂缺乏互动、教学效果难以测试等。

首先，学生参加在线课程的条件和环境没有保证。特别是在农村地区，由于网络条件差，家庭经济水平低，学生不能按时参加课程的直播，影响学习进度。此外，一些家长在家工作和玩耍也会产生噪音，干扰孩子的学习。

其次，网络课程教学方法单一，缺乏情感互动。从目前高校网络教学的现状来看，很多教师上课前并没有做好充分的准备，只有机械设置的报到、阅读教材和PPT。此外，由于电子设备的限制，即使打开相机，教师和学生仍然无法实现有效的情感交流，学生成为课堂内

容的被动接受者，极大地降低了他们的自主性。

最后，很难测试在线课程的学习效果。有些老师不强迫学生在课堂上打开相机，这给了他们分散注意力的机会。他们可以同时浏览微博或玩游戏，忽略课堂内容。在考试中，学生可以通过作弊获得高分，而不会被电子设备发现。此外，由于学生的学习效果不能真实、准确地反馈给教师，也会影响教师后续的教学活动。

只有学生、教师、家长和社会力量共同努力，才能克服这些问题，推动网络教育的发展和进步。
