数字化物理教学正在蓬勃发展，现已涵盖多媒体、虚拟仿真、人工智能等多代技术，以及电脑、手机等多种设备平台．作为一种动态网页脚本语言，JavaScript具有代码轻量化、交互性强，以及极佳的平台兼容性和可移植性等优势．本文用JavaScript编写了几个数字化物理教学课件，推进了建构主义的情景式、探究式、启发式教学．新技术可用于ETA物理教学全环节，在理论课、实验课、生活中不断增强学生的理论联系实际能力和创造力．

Digitalized physics teaching is flourishing and now covers multiple generations of technologies such as multimedia, virtual simulation, artificial intelligence, as well as various device platforms such as computers and mobile phones. As a dynamic webpage scripting language, JavaScript has advantages such as light-weight coding, strong interactivity, excellent platform compatibility and portability. We use JavaScript to develop several digital physics-teaching coursewares, pursuing the constructivistic ideals of situational, exploratory, and heuristic teaching. This new technology runs through the entire process of ETA physics teaching to continuously enhance students’ ability to connect theory with practice and creativity in theoretical, experimental classes, and daily life.
