“算法与程序设计”作为高中信息技术教学内容的选修模块,由于课程内容较为抽象,且逻辑思维性极强,“难教”和“难学”成为困扰该课程教学的最大痼疾。因此,从事“算法与程序设计”教学的教师,如何运用科学的教学方法,来提高学生的学习效率并且激发学生的学习兴趣,是算法与程序设计教学过程中必须要解决的一个重要问题。 As the elective module of high school information technology teaching content, because of its abstract content and strong logical thinking, “difficult to teach ” and “difficult to learn ” became a problem for the teaching of this course The biggest 痼 disease. Therefore, how to use scientific teaching methods to improve teachers ’learning efficiency and stimulate students’ interest in learning is an important problem that must be solved in algorithm and programming teaching .
