近几年的高考实验基本改变了过去的那种纯粹以“教材实验内容”为主的考查方式,而是以原来的学生实验为起点,通过改变原有实验的实验条件、仪器、目的、要求等提出新问题,引导学生运用已学的实验思想方法和理论来设计新的实验方案和处理方法, In recent years, the college entrance examination experiment has basically changed the type of examination that used to be based solely on the “experimental content” of textbooks. Instead, it uses the original student experiment as a starting point to change the experimental conditions, instruments, and purpose of the original experiment. And ask new questions and guide students to use the experimental ideas, methods, and theories they have learned to design new experimental programs and methods.
