微课在初高中数学衔接内容中的应用
The Application of Micro Courses in the Connecting Content of Mathematics between Junior and Senior High Schools

随着互联网时代硬件设备和软件技术的飞速发展、教育资源开放度逐渐提高，教育信息化在数学教学中的地位逐渐提升。以现代化教学方式著称的微课以其“短小精悍”的优势走近了数学教学之中。初中数学与高中数学之间在“质”“量”“思”“教”“学”等方面都存在着较大的差异，且初高中数学在知识上具有缝隙性、教材上具有断层感，这种知识的缝隙与教材的断层需要用初高中数学衔接内容来填补。将微课应用于初高中数学衔接内容中，不仅可以让学生不再对初中高中两个阶段的数学学习具有割裂感，优化了数学课堂，提高了教学与学习的效率和质量，而且还能实现数学课堂的精准性、针对性、高效性与层次性定位。
With the rapid development of hardware devices and software technology in the Internet era, and the gradual increase in openness of educational resources, the position of educational informatization in mathematics teaching is gradually improving. Micro courses, known for their modern teaching methods, have entered the field of mathematics teaching with their “short and concise” advantages. There are significant differences in terms of “quality”, “quantity”, “thinking”, “teaching”, and “learning” between junior high school mathematics and senior high school mathematics. More-over, junior high school mathematics has gaps in knowledge and a sense of discontinuity in text-books. This gap in knowledge and the gap in textbooks need to be filled with the content of junior high school mathematics connection. Applying micro courses to the connection between junior and high school mathematics can not only help students no longer have a sense of separation between the two stages of middle and high school mathematics learning, optimize the mathematics class-room, improve the efficiency and quality of teaching and learning, but also achieve the accuracy, targeting, efficiency, and hierarchical positioning of the mathematics classroom.
