随着教育现代化步伐日益加快,信息技术在课堂教学中得到广泛应用,数学教学理念也发生了较大变化。构筑以“核心主线”为路径,以“问题串”为路标,以“问题解决”为动力的教学框架以及运用嵌入自主研发数字化资源的网络教学平台开展数学教学活动,是以学生为本的教学实践创新,也是智慧运用信息技术于教学活动的行动研究。 With the accelerating pace of education modernization, information technology has been widely used in classroom teaching, mathematics teaching philosophy has also undergone major changes. Constructing a teaching framework motivated by “Problem Struts ” with “Problem Strings ” as the path, “problem solving ” as the motive, and carrying out the mathematics teaching activities by using the online teaching platform embedding self-developed digital resources Student-based teaching practice innovation, but also the wisdom of the use of information technology in teaching activities of action research.
