新课程标准指出,中小学信息技术课是以培养学生的信息素养为核心、面向学生全面发展的一门课程.面对信息技术发展的日新月异,教学内容很难超前或与发展同步.学生学习到的一些信息技术知识与技能,过不了多久往往就会过时.因此,教师在注重介绍基本操作与技能、用计算机处理信息的基本方法等相对稳 The new curriculum standards point out that the primary and secondary school information technology courses are based on cultivating students’ information literacy as the core and facing all-round development of students. Faced with the ever-changing development of information technology, it is difficult for teaching content to advance or synchronize with development. Some of the information technology knowledge and skills will often become obsolete soon afterwards. Therefore, teachers are relatively stable in focusing on basic operations and skills, and basic methods for processing information using computers.
