I. Total class hours of local and school courses. According to the national regulations and the actual situation in Shandong, our province has arranged and comprehensively utilized local courses, school courses and comprehensive practical activities (including information technology, community service, social practice and labor technology education) in the compulsory education stage, accounting for 16.8% of the total nine-year class hours, which is about 1600 class hours according to the calculation of 36 weeks of class hours in each academic year. Second, about the scope of local courses. The local curriculum in our province consists of three areas: national culture, social inquiry and natural inquiry. There are several courses under each area, and each course is generally 18 or 36 class hours. Information technology education is a relatively independent discipline and a local course. Community service and social practice can be arranged separately as school courses or in combination with local courses.
