随着教育改革的不断深化,实验在教学中的地位越来越重要,作用越来越明显,它已从传统教学的辅助地位上升为教学中不可缺少也不可替代的主导地位。近几年各种专业刊物中有很多论文都证明了化学实验是学生学习化学和进行探索的重要且不可替代的资源。那么,在新形势下化学实验的新理念到底是什么?我们在面对学生时又该如何有效地利用化学实验这种资源呢?新课标强调突出学生的主体性,这种理论与“建构主义理论”是相通的。建构主义认为,知识不是通过教师传授得到,而是学习者在一定的情境即社会文化背景下,借助其他人(包括教师和学习伙伴)的帮助,利用必要的学习资料,通过意义建构的方式而获得的,学习者是学习的中心,是信息加工的主体,是意义的主动建构者。从实验自身的特点上看实验是落
With the continuous deepening of education reform, the role of experiment in teaching has become more and more important and obvious. It has risen from the auxiliary position of traditional teaching to an indispensable and irreplaceable leading position in teaching. In recent years, many papers in various professional journals have proved that chemical experiments are an important and irreplaceable resource for students to learn chemistry and explore. So, in the new situation under the new concept of chemical experiments in the end? We face the students how to effectively use the resources of chemical experiments? The new curriculum emphasizes highlighting the subjectivity of students, this theory and Constructivism "is interlinked. Constructivism holds that knowledge is not taught through teachers. Instead, learners, with the aid of other people (including teachers and learning partners), using the necessary learning materials and through the construction of meaning in certain contexts, that is, social and cultural backgrounds Acquired, learners are the center of learning, the main body of information processing, the active constructor of meaning. Experiment from the experimental point of view the experiment is falling
