摘要小学科学课程标准倡导跨学科的学习方式,希望将科学、技术、工程、艺术、数学有机地融合为一体,培养学生的创新能力。“自制指南针”项目的目的,就是让学生体验包括设计、实施、改进在内的简单的技术与工程实践过程。“自制指南针”由三部分组成:第一部分是利用一段有趣的动画片来激发学生制作指南针的兴趣。第二部分是实验探索,通过提问和演示引导学生成功制作一个水浮式指南针。第三部分是拓展研讨,教师拓展指南针的发展历史,学生对“利用新方法再做一個指南针”这个问题进行研讨。本项目的主线是制作一个水浮式指南针,而重点在于让学生体验包括设计、实施、改进在内的简单的技术与工程过程,培养他们的动手制作能力和创造意识,并能对制作过程或测试结果中出现的问题提出改进方法。

Abstract: The primary school science curriculum standard advocates an interdisciplinary learning method, hoping to organically integrate science, technology, engineering, art and mathematics, so as to cultivate students’ innovative ability. The purpose of "homemade compass" project is to let students experience simple technical and engineering practice processes including design, implementation and improvement. "Homemade compass" con? sists of three parts: the first part uses an interesting cartoon to stimulate students’ interest in making compass. The second part is experimental exploration, which guides students to successfully make a water floating com? pass through questions and demonstrations. The third part is to expand the discussion. Teachers expand the de? velopment history of compass, and students discuss the problem of "making another compass with new meth? ods". The main line of this project is to make a floating compass, and the focus is to let students experience simple technical and engineering processes including design, implementation and improvement, cultivate their hands-on production ability and creative consciousness, and put forward improvement methods for problems in the production process or test results.

项目分析
“自制指南针”由三部分组成:第一部分是利用一段有趣的动画片来激发学生制作指南针的兴趣,聚焦到本项目的主要任务——做一个水浮式指南针。第二部分是实验探索,为学生提供钢针、菱形吹塑纸、条形磁铁、装有水的盘子、指南针这几种材料,通过提问和演示引导学生成功制作一个水浮式指南针。第三部分是拓展研讨,教师拓展指南针的发展历史,学生对“利用新方法再做一个指南针”这个问题进行研讨。
本项目的主线是制作一个水浮式指南针,而重点在于让学生体验包括设计、实施、改进在内的简单的技术与工程过程,培养他们的动手制作能力和创造意识,并能对制作过程或测试结果中出现的问题提出改进方法。……
