根据《课程标准》的要求和新的科学教育研究成果,结合四上年级科学教学目标中包含的“科学概念”、“过程与方法”、“情感、态度与价值观”三个方面的要求,就科学分组实验中的教师指导做了初步探析。学生在探究过程中需要老师准确、到位的指导;如果教师“指导不足”会使学生的实验效率低下,很难有大的实验成果。准确指导学生的分组实验,明确教师的主导作用和学生的主体地位,这是学生分组实验成功的保证。
According to the requirements of “Curriculum Standard” and the new scientific education research results, combined with the “scientific concepts”, “processes and methods”, and “feelings, attitudes and values” contained in the fourth grade scientific teaching objectives Aspects of the requirements of the scientific grouping experiments conducted a preliminary analysis of the instructor. Students need teachers in the process of inquiry, accurate guidance in place; if the teacher “lack of guidance ” will make the students experiment inefficient, it is difficult to have big experimental results. Accurately guide students in grouping experiments, a clear role of teachers and the dominant position of students, which is a guarantee of the success of the student group experiments.
