核心素养的低成本实验要求教师具备的核心素养,是教师言传身教、潜移默化地促进学生科学素养的提升。作为教学主导,教师应具备扎实的专业知识、不断更新的教育理念和“信手拈来”的低成本实验制作。每每想起“知识全还给老师您了,学费能否还给我”诸如此类戏言,我不禁深思:物理课程的价值是什么呢?大教育家冯·劳厄说过:教育给予我的是当所有学过的都忘后所留下的东西。物理研究的内容和规律可能随时间流失而遗忘,然而研究的思想方法、解 The core literacy low-cost experiments require teachers with the core literacy, is the teacher precept and example, subtly promote the improvement of students’ scientific literacy. As a leading teaching, teachers should have solid professional knowledge, constantly updated educational philosophy and “low cost ” experimental production. I often wonder: what is the value of physics curricula? Von Laue, a great educator, said: What education has given me is that “if the knowledge is all returned to the teacher, can the tuition be returned to me?” When all learned forgotten what left behind. The content and laws of physical research may be forgotten with the loss of time. However, the research methods and solutions
