信息技术课程是一门新生的课程。信息技术教师在课堂上管理的方法多种多样,可是在有些特殊的环境下,比如是在机房上网络课,管理起来非常不便。一些学生无意间浏览到一些不健康的网站,下一节课的同学在输入网址时,碰巧输入某个字符,在地址栏中自动弹出下拉列表(不健康网站网址)。如果教师发现及时予以制止,但多数情况下,未能及时发现。有网络过滤功能的机房,可设置参数来禁止访问不健康的网站,这种方法只适合一些规模较大的学校,而对一些小而穷的学校是不符合实际的。如果让机器自己删除一些不必要的网址,那该多好啊!现笔者介绍一些方法给同行,共同讨论。
The information technology course is a freshman’s course. There are many ways in which information technology teachers can manage in the classroom, but in some special circumstances, such as online classes in the computer lab, management is very inconvenient. Some students inadvertently browse unhealthy websites. When the next class of students enters a website, they accidentally enter a character and automatically pop up a drop-down list (unhealthy website URL) in the address bar. If teachers find that they are stopped in time, but in most cases, they are not discovered in time. In a computer room with network filtering, parameters can be set to prohibit access to unhealthy websites. This method is only suitable for some large-scale schools and is not practical for small and poor schools. If you let the machine delete some unnecessary URLs yourself, that would be great! Now the author introduces some methods for peers to discuss together.
