无机化学实验的创新教学设计——以海盐制备试剂级氯化钠实验为例

Innovative Teaching Design of Inorganic Chemistry Experiment:Taking the Salt-prepared Reagentgrade Sodium Chloride Experiment as an Example

无机化学实验课程是高等学校重要基础实验课程,也是其他后续实验课的基础。实验课的学习,不但能加深学生对无机化学基本理论、基础知识的理解和掌握,也能提高学生观察问题、解决问题的能力。以海盐制备试剂级氯化钠实验为例,创新设计了教学内容,建立了一个立体的、多层次的教学模式,使学生不但很好地掌握了实验内容,拓展了知识面,也提高了学生动手能力和创新意识。

Inorganic chemistry experiments are important basic experimental courses in colleges and universities and the basis of other follow-up experimental courses.Through the study of the experimental class,not only can students deepen their understanding and mastery of the basic theory and basic knowledge of inorganic chemistry,but also improve their ability to observe and solve problems.In this paper,the experiment of sea salt preparation reagent grade sodium chloride is taken as an example.The experimental teaching contents is designed innovatively,and a three-dimensional and multi-level teaching mode is established,so that students not only master the experimental content well,but also greatly improve the training of students'practical ability and innovation consciousness.
