基于CDIO模式的高中“化学反应与热能”项目式学习——自热饭盒的设计与制作

Project-Based Learning of"Chemical Reaction and Thermal Energy"in Senior High School Based on CDIO Mode:Design and Manufacture of Self-Heating Lunch Box

以“化学反应与热能”为项目主题,选择“自热饭盒的设计与制作”为项目载体,应用CDIO工程教育模式开展项目式学习活动。学生通过完成“构思自热饭盒加热方案”“设计与绘制加工图纸”“学习与应用3D打印技术”“成果汇报与评价反思”等4个CDIO子项目,深入学习化学反应与热能、高分子材料等化学知识,训练数学与经济思维,培养美学设计能力和严谨的理工科思维,最终树立使用跨学科知识与技能助力人类社会可持续发展的价值观念,发展核心素养。

With"chemical reaction and thermal energy"as the project theme and"design and production of self-heating lunch box"as the project carrier,the CDIO engineering education mode was applied to carry out project-based learning activities.By completing four CDIO sub-projects namely"conceiving lunch box heating scheme""designing and drawing engineering drawings""learning and applying 3D printing technology"and"achievement report and evaluation",students could deeply learn chemical knowledge such as chemical reaction and thermal energy and polymer materials,train mathematical and economic thinking,and cultivate aesthetic design ability and rigorous scientific and engineering thinking.Finally,students established the value concept of using interdisciplinary knowledge and ability to help the sustainable development of human society and developed the core literacy.
