无论是化学基本知识的学习,还是基本技能的培养,其过程中总要面对多种不确定因素,或是知识本身的局限,或是在运用知识过程中出现的问题。因此,化学课堂教学要充分利用不确定因素,努力探求更合理、更科学的学习方式,激发学生探究科学奥秘的积极性。一、精心预设非确定性问题情境,培养学生的探究意识 Whether it is the study of basic knowledge of chemistry or the cultivation of basic skills, there are always many uncertainties in the process, or the limitation of knowledge itself or the problems that arise in the process of applying knowledge. Therefore, the chemistry classroom teaching should make full use of the uncertain factors, make efforts to explore a more reasonable and scientific way of learning, and stimulate students’ enthusiasm to explore the mysteries of science. First, elaborate non-deterministic situation, develop students’ awareness of inquiry
