微课以微视频为核心,资源构成多样,学习情景真实,具有主题突出、针对性强、交互性强的特点。在小学数学教学实践中,巧妙运用微课辅助教学,可以实现:精彩课堂导入,充分调动学生的学习热情;高效突破教学难点,提高教学的效率;激励学生自主学习。因此,把“微课”引入课堂,使得课堂教学更加精彩、灵动、高效。 Micro-class micro-video as the core, resources, diverse, real learning scenarios, with prominent themes, targeted, interactive features. In the practice of primary school mathematics teaching, we can make use of the teaching mode of micro-class, which can be achieved: wonderful classroom introduction, full mobilization of students’ enthusiasm for learning; efficient breakthrough of teaching difficulties and improvement of teaching efficiency; motivating students to study independently. Therefore, the “micro class ” into the classroom, making classroom teaching more exciting, smart and efficient.
