美国教育家杜威认为:教育即生活,教育过程就是一个连续不断的生长过程。课堂教学与生活有密切联系,生活既是课堂教学的起点,又是课堂教学的归宿。《义务教育物理课程标准》指出:“物理来源于生活,又要回到生活中去。教师要紧密联系学生的生活环境,从学生的经验和已有的知识出发,创造生动的物理情景。” Dewey, an American educator, believes that education is life and education is a continuous process of growth. Classroom teaching is closely related to life. Life is both the starting point of classroom teaching and the destination of classroom teaching. The “Course Standard for Compulsory Education Physics” points out: “Physics come from life and go back to life. Teachers need to closely connect with students’ living environment and create vivid physical scenes based on students’ experience and existing knowledge. ”
