A Study On The Creation Of Chemistry Situation In Senior High School Under The Core Literacy

“Ordinary Senior High School Chemistry Curriculum Standard”(2017)has spoken of the importance of cultivation of chemistry core literacy,which includes five dimensions:macro identification and micro analysis,change concept and balance thought,evidence reasoning and model cognition,experimental exploration and innovative consciousness,scientific spirit and social responsibility.How to develop chemistry core literacy through classroom teaching is the most concerned problem in middle school chemistry teaching.Actually,creating the proper situation for teaching is a critical element to cultivate students' chemical core literacy in classroom teaching because it can well materialize abstract knowledge,rationalize perceptual knowledge as well as enable students to become the active participant in class and the active exporter of knowledge.In recent years,there are many researches concentrating on the creation of situation and the core literacy,while little attention has been paid to the creation of high school chemistry teaching situation under the core literacy.Therefore,this thesis focuses on the theme of “the study on the creation of high school chemistry situation under the core literacy”.Based on the extensive reading of literature,the writer understands the current situation and the meaning of the core literacy as well as the researches on situation creation both home and abroad.And through questionnaire survey,the writer also knows the condition of the high school students' chemical core literacy and the current situation of the application of situation creation in class.Based on the results,this thesis studies the situation creation according to the five dimensions of chemistry core literacy.And the specific strategies are as follows: creating problem situations to guide students to understand the connection between macro phenomena and micro essence;creating analogy situations to encourage students to develop a systematic and“macro” chemical concept;creating questioning situations to change students' traditional mindset;creating “students' experience situations” to stimulate students' cognitive conflicts and change concepts;creating model situations to experience the process of chemical model construction;creating reasoning situation to improve students' scientific reasoning ability;creating experimental situations to cultivate students' ability to find,put forward and solve problems in experimental explorations as well as innovative consciousness;creating chemical history situation to establish the correct concept of chemistry;and creating the social situation to cultivate students' sense of social responsibility.Finally,according to the actual situation of chemistry courses in senior high school,this thesis,taking the mobile teaching of redox reaction and chemical balance as an example,designs and analyzes the teaching case that focuses on the development of core literacy.Combining with the result of questionnaire survey,this thesis concludes that the creation of situational teaching helps to cultivate students' core literacy,having a positive impact on improving students' interest in learning,enhancing their learning ability as well as deepening their understanding of knowledge.
