Research On The Context Creation Of High School Chemistry Teaching Based On Core Literacy

The newly revised "The Senior High School Chemistry Curriculum Standards" in2017 put forward the core literacy curriculum goals,marking the formal start of the reform of the chemistry curriculum that aims at core literacy.The new chemistry curriculum standard emphasizes the creation of context to cultivate the core literacy of chemistry.Situation creation has always been an important method in classroom teaching,and it is also an inevitable choice to meet the needs of curriculum reform and cultivate core literacy in chemistry.On the basis of reviewing the existing studies of context creation research at home and abroad,the thesis defines the concepts of context creation and core literacy under the guidance of constructivist theory and context cognitive theory.Taking 6 model chemistry classes in Shandong province in 2019 for example,the teaching context evaluation criteria based on core literacy are used,and analysis and assess are conducted from the three dimensions of composition,function and process characteristics.In the meanwhile,the interview method is used to summarize the current difficulties of teachers in creating context,and to sum up the achievements and problems in the creation of context in the current chemistry classroom.Based on the the current situation analysis of context creation,the core literacy-based high school chemistry teaching situation creation model is proposed,including creation goals,creation principles,creation process and situation evaluation.And context creation strategies are proposed,including: designing a series of teaching situations according to teaching and evaluation objectives;creating teaching situations that can cultivate higher-order thinking;creating teaching situations that can cultivate students' scientific attitude and social responsibility.Finally,the proposed teaching context creation strategies of high school chemical is applied to the specific teaching design,and the thesis also explains how to apply these teaching strategies in practical teaching.Whereas high school chemistry knowledge can be divided into two parts: chemical concepts and elemental compounds,this part carries out the teaching design of the unit“Redox reaction”that is one of the typical chemical concepts and principles,and the teaching design of the class“Ferrous salt and iron salt ” that is one of typical elemental compounds.Each instructionaldesign revolves around curriculum standards analysis,academic analysis,chemistry learning content analysis,teaching objectives analysis,teaching resources analysis,context creation,teaching process and teaching reflection,in order to fully reflect the application of teaching context creation strategy in practical teaching.
