TPACK视域下的高中数学教学设计研究

Research on High School Mathematics Instructional Design in the Perspective of TPACK

摘要: 随着中国教育体制改革的深入，信息技术与课程的有机整合是新课程改革的热点话题，TPACK (整合技术的学科教学知识)的研究是这一热点话题的典型代表，根据《普通高中数学课程标准(2017年版) 2020年修订》对三角函数的内容要求，通过信息技术与课程教学整合，借助GeoGebra软件精准并动态地演示筒车灌溉过程，并建立 函数模型，利用软件中滑杆的滑动，让学生主观感受各参数对三角函数图像的影响，在这个过程中，采用启发式教学法、讨论法和实践法等教学方法，做到技术、教学法和知识的深度整合，从而让学生更好地理解三角函数中的知识点，减弱对三角函数的惧怕感，提高学习兴趣，让学生主动发现、探索知识，在提高教学质量的同时提升学生的数学素养。

Abstract: With the deepening reform of China’s education system, the organic integration of information technology and curriculum has become a hot topic in the new curriculum reform. Research on Technological Pedagogical Content Knowledge (TPACK) serves as a typical representative of this hot topic. According to the “Revised 2020 Edition of the High School Mathematics Curriculum Standard (2017 Version),” the content requirements for trigonometric functions, through the integration of information technology and curriculum instruction, the precise and dynamic demonstration of the process of water irrigation by a sprinkler cart can be achieved using GeoGebra software. A function model of can be established. By manipulating the sliders in the software, students can subjectively experience the influence of various parameters on the graph of trigonometric functions. In this process, teaching methods such as heuristic teaching, discussion, and practice are employed to achieve a deep integration of technology, pedagogy, and knowledge. This enables students to better understand the key points of trigonometric functions, reduce their fear of trigono-metric functions, increase their interest in learning, and encourage students to actively discover and explore knowledge. By improving the quality of teaching, students’ mathematical literacy is enhanced.
