1、 I 网上选课网上选课系统的开发与设计系统的开发与设计 摘摘 要要 网上选课系统是针对在校学生和教师使用，从学生的角度来说，由于学校教 学制度的改革，现在大部分高等院校开始实行的是学生的自主选课模式，传统的 教学模式（学生按照学校安排好的课程上课）已经不能适应新型的教学手段，如 果仍然通过纸上的方式选课，一方面浪费的大量的人力、物力资源，另一方面浪 费时间以及在人为的统计过程中不可避免出现的差错等情况。 随着高校人数的增 多，这种弊端会越来越多的暴露出来。因此，利用网络，使学生只要在计算机前 输入自己的个人选课信息即可完成原来几倍的作业量。从教师的角度来说，同样 是节省了大量的工作量， 由于教

From the teachers point of view, also save a lot of workload. as proposed by substitute teachers for completion of the course work published more than students in course selection in terms of complexity. it can be released through online courses greatly reduce the work of teachers volume. reducing the occurrence of the error probability. As a teacher, also as long as the computer to operate by their own can, no need to rush in bet
