守正创新，精准赋能:新时代教师多媒体技术应用优化路径探究以中学思政学科教师为例

解亚伟，庞 涛

摘 要:在教育数字化转型背景下，多媒体技术与学科教学的深度融合已成为提升课堂育人实效的重要路径。然而，实践中技术应用脱离教学目标、素材过载冲淡重难点、演示节奏过快留白不足等问题突出。本文以中学思政学科为研究场域，基于维果茨基的最近发展区理论、认知负荷理论等，系统阐释多媒体技术在思政课堂中的育人价值，剖析教师应用中的突出问题及其成因，从目标锚定、素材精炼、节奏调控三个维度提出优化策略，旨在为新时代教师科学运用多媒体技术、落实核心素养培育提供理论参考与实践指引。

Abstract: Against the backdrop of educational digital transformation, the deep integration of multimediatechnology with subject teaching has become a critical path for enhancing classroom effectiveness. However, practicalproblems persist, including technology application detached from teaching objectives, excessive material dilutingkey points, and an overly fast presentation pace with insufficient reflection time. Taking middle school ideologicaland political education as the research field, the research systematically explains the educational value of mulimediatechnology based on Vygotsky's Zone of Proximal Development theory and Cognitive Load Theory. It analyzesprominent problems and their causes, and proposes optimization strategies from three dimensions: objective anchoring.material refinement, and pace regulation, aiming to provide theoretical reference and practical guidance for teachers toscientifically apply multimedia technology and cultivate core competencies.

Keywords: educational digitalization; multimedia technology application; middle school ideological and politicalcourse; core competencies; teaching-learning-assessment alignment
