信息技术是一门实践性很强的学科,同样的目标要求下去,学生在课上的完成情况差距很大。统一的目标要求很大程度上造成学生在课堂上学不会或者学不好,学习积极性下降。因此,分层次设立目标教学成为必然的选择。 Information technology is a highly practical subject, with the same goals and requirements, and a wide range of student achievement in class. The goal of unification is to a great extent causing students to fail to learn or not to learn in the classroom, and the enthusiasm for learning decreases. Therefore, the establishment of targeted teaching at different levels has become an inevitable choice.
