化学实验给学生提供了最直接的观察对象,而用定量的手段或定量的眼光来实施或观察实验,是化学实验从单纯的感性认知过程向理性探究过程的转变。因此在教学中引人“定量”手段或建立“定量”意识不仅拓展了学生在实验观察中的视角,而且在一定程度上改变了学生原有的认知过程,影响了学生学习的心理状态,增强了学生与周围世界进行对话一、教材定量实验内容分析定量实验的专题化学习是上海高中化学教材的亮点之一。学
Chemistry experiments provide students with the most direct observation of objects, but quantitative means or quantitative vision to implement or observe the experiment is a chemical experiment from a simple perceptual cognitive process to a rational process of inquiry. Therefore, introducing “quantitative” means or establishing “quantitative” awareness in teaching not only expands students’ perspectives in experimental observation, but also changes students’ original cognitive process to a certain extent and affects students’ learning Of the psychological state, and enhance the students to dialogue with the world around a quantitative analysis of teaching materials Quantitative experimental monographic learning is one of the highlights of Shanghai High School chemistry textbooks. learn
