中等学校开展计算机教学,是提高民族科技素质的重要环节。学习计算机语言的关键是要按照计算机语言的语法规則来正确编写语句和程序,这只有通过大量的编程练习和上机实习才能掌握。由于教育资金的不足,我国只有少数重点中学才有可能建立计算机实验室开设计算机课程。大多数中学则由于没法向学生提供足够必需的上机实习机会,免开计算机课, The development of computer teaching in secondary schools is an important part of improving the national science and technology quality. The key to learning computer languages ​​is to write sentences and programs correctly in accordance with the grammar rules of computer languages, which can only be mastered through extensive programming exercises and hands-on internships. Due to the lack of educational funds, only a few key high schools in China are likely to set up computer labs to open computer courses. Most secondary schools are unable to provide enough necessary internship opportunities to students and avoid computer classes,
