定量实验是利用专门仪器和化学反应计量关系来确定某些因素的数值等进行的实验。定量实验在学生的培养目标方面扮演着极为重要的角色。首先,它能帮助学生树立“量”的意识。定量实验能充分体现化学学科正逐步向定量化过渡的特征,能有效地引导、启发学生学会运用适当的数学方法从定量的角度分析并解决化学中的有关问题。其次,它有助于提高学生的科学素养。定量实验既能帮助学生形成化学概念,又能培养学生的观察能力、化学知识综合运用能力等,从而提高 Quantitative experiment is the use of specialized equipment and chemical reaction measurement relationship to determine the value of certain factors such as experiments. Quantitative experiments play an extremely important role in the training of students. First, it helps students establish a “volume” awareness. Quantitative experiments can fully reflect the characteristics of chemistry subject that is gradually changing to quantitative. It can effectively guide and inspire students to learn and solve problems related to chemistry quantitatively using appropriate mathematical methods. Second, it helps to improve students’ scientific literacy. Quantitative experiments can not only help students to form a chemical concept, but also develop students’ observation ability, comprehensive utilization of chemical knowledge and so on, thus improving
