Abstract: In order to solve the problems of insufficient experiment time, excessive experiment content, and limited training of students' innovation and application ability in the Computer Software Foundation course, the content and form of the in-class experiment were improved. In terms of content, on the basis of the simple verification design, combined with typical applications, practical application design is added to cultivate the students' innovation and application ability. In terms of form, the experiment was designed as a level-style practical training project. Taking the "Sequential Stack" as an example, a practice project with multiple levels was designed and implemented in the Educoder online practice teaching platform. The platform provides the students with an online practical training environment and testing tools, meticulous recording of the student's experimental process, and the automation and intelligent evaluation of experimental results. Practice results show that the project training experience of game breakthrough can effectively stimulate the students' interest and motivation in learning, and further enhance the training of programming ability and application ability. This design has reference significance for the construction of an online practice platform for program design experiments under the background of application-oriented undergraduate education construction.
