胡萝卜牙签搭高塔：跨学科视角下的小学科创项目探索
摘要：文章结合多年的教学实践，以“胡萝卜牙签搭高塔”项目为具体载体，构建了问题驱动、任务分解、技术赋能、评价闭环的跨学科项目式学习模式。该项目有机融合科学、数学、工程、技术等多学科知识，通过入项启动、方案设计、搭建实践、优化改进、出项展示五个递进式环节，依托信息化工具，着力培养学生的科学探究、工程实践与团队协作能力。经过多轮课堂实践与校级竞赛检验，项目学生参与率与任务完成率均达100%，学生的知识应用能力、问题解决能力得到显著提升，为小学科创活动实施提供了可直接借鉴、易于复刻的实践案例。

Building Towers with Carrots and Toothpicks: Exploring Elementary School Innovation
Projects from an Interdisciplinary Perspective
Based on years of teaching practice, this article uses the "Carrot and Toothpick Tower" project as a concrete case to establish an interdisciplinary project-based learning model driven by problem-solving, task decomposition, technology empowerment, and a closed-loop evaluation system. The project organically integrates knowledge from multiple disciplines such as science, mathematics, engineering, and technology. Through five progressive phases—project initiation, design planning, construction practice, optimization and improvement, and final presentation—and supported by information technology tools, it focuses on cultivating students' abilities in scientific inquiry, engineering practice, and teamwork. After multiple rounds of classroom implementation and school-level competitions, the project achieved a 100% student participation rate and task completion rate. Students demonstrated significant improvement in their ability to apply knowledge and solve problems. This project provides a practical case that can be directly referenced and easily replicated for implementing innovation activities in elementary schools.
