【正文】 he teaching courses and work, also made it is necessary to establish the “schoolbased” work teaching platform. It will design and develop the sites for theme study, bring into full play to the advantages of works, break through the traditional closedend teaching, with the help of opening and interactive new teaching medium it will fulfill the new teaching model with the anic bination of Inter and teaching and the new learn ways of students. This thesis firstly analysis the current situation of embedded system education’s teaching mode and the training of the university’s majors of puter work, and discussed the necessity to establish a teaching site with a construction of a B/S, based “embedded work teaching platform”, used the site as a platform to study the settings of the user access and the technology of online mock examination system. Finally, based on the design of JSP dynamic web, the application of CSS form, the production of static web, the processing of Photoshop image, JavaScript language, Java language and the design for the overall layout of the site to develop and realize the major sections of teaching, study guides online examination and curriculum design and so on. The main bodies of this thesis are teaching modules, study guides and online test module. The embedded systems work teaching platform will give students an exchange and interaction platform and laid a solid base for students’ study of embedded systems.
