Research On Teaching Design Of Chemical Preparation Experiments For Scientific Inquiry And Innovation Awareness

The promulgation of the "General Senior High School Chemistry Curriculum Standards" puts forward new requirements for students’ innovative awareness.How to implement the core literacy in the chemistry experiment and give play to the cultivation effect of the experiment on students’ scientific inquiry and innovation consciousness is a question that chemistry educators need to think about.Therefore,this research investigates the status of scientific inquiry and innovation awareness of a high school student in Ningbo and the current status of chemistry experiment teaching,and designs teaching cases that point to the preparation experiment of scientific inquiry and innovation awareness,teaching practice and suggestions.This research is mainly carried out from the following aspects:The first part includes the first and second chapters.On the basis of clear research background,research purpose and significance,the literature method is used to understand the current research status of Scientific inquiry and innovation consciousness and chemistry experiment teaching at home and abroad.The second part is field investigation and analysis.Through the questionnaire method and interview method,the current situation of high school chemistry experiment teaching and students’ innovation consciousness is analyzed,and the existing problems are clarified.The third part is teaching design,based on existing problems,designing the teaching mode of chemical preparation experiment based on innovation consciousness.The corresponding teaching strategies are proposed.The fourth part is the practical research and result analysis.The teaching design is applied to practice,and the teaching case of the preparation of ferrous ammonium sulfate is designed.The differences between the two classes of students’ scientific exploration and innovation awareness literacy level are compared and analyzed in the way of performance evaluation and student interview,so as to explore the development of the new mode of scientific exploration and innovation awareness literacy of students and analyze the teaching The last part is the conclusion and reflection,summarizing the viewpoints of this study,making suggestions on the teaching mode of chemical experiment,and reflecting on the shortcomings of this study.The research shows that the experimental teaching design plays an active role in improving students’ scientific exploration and innovation awareness.By improving the preparation experiment to the inquiry experiment designed by students themselves,not only is it helpful to arouse students’ enthusiasm for learning,but also to train students’ ability of finding,analyzing and solving problems,which is helpful to the promotion of innovation consciousness.At the same time,the ability of scientific inquiry of students in the whole process of preparation experiment has also been improved.
