A Study On The Teaching Design And Practice To Cultivate The Core Competencies Of Chemistry That Integrate Into Chemistry History

The New High School Chemistry Curriculum Standards(2017)advocate literacy-based teaching,the creation of real-life scenarios to conduct a variety of research activities,which focused on chemical experirments.The new chemistry curriculum standard also mentions that the actual chemical history in the experimental proposal as an extremely valuable scene material.From the new chemistry curriculum standard,we can see that curriculum concepts,teaching strategies,and material content fully affirmed the importance of the history of chemistry in many aspects.How to select the chemical history with unique educational value to organically integrate into the teaching,to improve the student's chemical core culture is purpose of the research.First of all,through the study analysis method,we have learned about the teaching value,strategy,approach of the history of chemistry,and the current problems faced by teachers and students through the questionnaire survey.We choose comprehensive teaching topics by means of comprehensive analysing of new curriculum standards,textbooks,and chemistry history.After selecting the theme of“electrolyte and ionization”,the teaching design history was completed after the integration of the chemical history of electrolytes with ionization theory.Students'chemical literacy was improved through specific teaching.In the specific teaching,the debate on the development history of ionization theory was introduced.Through experiments,students were guided to construct the concept of electrolyte and ionization twice.Besides,the teaching effect is analyzed and concluded that the teaching content of electrolyte and ionization introduces the development history of ionization theory,and it has achieved certain teaching effects in cultivating students macro and micro integration and scientific inquiry literacy.The introduction of the discovery and development history of chlorine in the teaching theme of the "Nature of Chlorine," after the implementation of the teaching,a comprehensive analysis has yielded good results in the teaching of this lesson in scientific inquiry and creative awareness,scientific attitudes,social responsibility,literacy and macro integration to achieve good teaching effects.
