学生是实验的主人,但真正要让学生“做主”,让学生会“做主”,却并不是那么简单的事情。凡事都不可能一蹴而就。在小学自然(科学)实验设计的教学中,让学生一开始就一步到位地独立设计实验方案是不现实也是不可能的,特别是对中低年级学生而言。教师只有充分调动学生学习的积极性,向学生提供从事实验活动的机会,帮助他们在自主探索和合作交流的过程中理解和掌握相应的科学知识与技能,使他们获 Students are the masters of experiments. However, it is not so simple for students to “call the shots” for the students to “call the shots.” Everything can not be accomplished overnight. In the teaching of primary (natural) (science) experimental design, it is impractical and impossible for students to design experimental programs independently from the very beginning, especially for lower and middle-grade students. Only by fully mobilizing students’ enthusiasm for learning, teachers can provide students with the opportunity to conduct experimental activities so as to help them understand and master the scientific knowledge and skills in the process of exploration and cooperation and make them
