Inquiry-based Teaching Practice Of Chemistry Experiments Based On Core Literacy

The core literacy model is constructed in the National Curriculum Standards of General High School(2017 edition 2020 revision).The core literacy emphasizes that students should possess systematic and structured knowledge and skills of the subject through curriculum teaching to form a comprehensive quality which enables students to flexibly integrate domain-specific knowledge and skills,form thinking inquiry patterns,attitudes and values,understand complex reality situations and solve problems.In the process of exploring chemical experiment,students can explore and touch some indescribable things,deeply feel the mystery of chemistry and the fun of learning chemistry.The chemical experiment teaching can cultivate students’ practical ability,thinking ability and innovation ability.The training goal of chemical experiment is in good agreement with that of core literacy.The author studies the optimization and application of inquiry-based chemistry experiment teaching in senior high school under the core literacy,which provides some references for front-line educators.Part I: The author combs the related literature,illustrates research background,studies the current situation of inquiry-based research in high school chemistry experiment at home and abroad,and explains the research objectives and methods.Part II: The author defines some important concepts such as core literacy,chemistry core literacy,inquiry teaching,and chemistry experiment inquiry teaching and lists the relevant educational theories.Part III: The author investigates the implementation of exploratory chemistry teaching and experimental chemistry teaching in senior high schools in Dancheng County through student questionnaires,teacher questionnaires and teacher interviews,studies the problems in the implementation of inquiry teaching in high school chemistry experiment and analyze the reasons.Part IV: According to the teaching situation and literature materials in the area where I live,the principles of experimental inquiry teaching design suitable for this region are put forward,which are subjectivity principle,openness principle,hierarchy principle,autonomy principle and cooperation principle.According to the experimental inquiry teaching link,the author puts forward the design strategies of experimental inquiry teaching: teaching goal design strategy,teaching content design strategy,teaching situation design strategy,teaching activity design strategy,teaching program optimization design strategy.Part V: Two classes with small achievement gap are selected and set as experimental class and control class.The inquiry teaching mode is adopted in the experimental class and the conventional teaching method in the control class.Based on the mode of inquiry-based experimental teaching,the author conducts practice,tests the effect of practice,carries out the horizontal comparison of results of the experimental class and control class before and after experiments,analyzes the influence of inquiry experiment teaching on senior high school students’ learning chemistry,makes a post-test questionnaire survey to the students in the experimental class after the experiment,and understands the influence of inquiry experiment teaching on the comprehensive ability of students from a longitudinal perspective.Based on the practical activities in high school textbooks-the detection of iron in Auricularia Auricula,physical properties-active metal-sodium,chemical principles-primary batteries,the inquiry teaching is designed and explained.Part VI: The conclusion is that the inquiry teaching mode of chemical experiment driven by core literacy can improve students’ core literacy,increases their interest of learning,form a better learning ability,cultivates students’ inquiry learning ability,enhances their consciousness of exploring the nature.It will lay the foundation for students’ exploring the unknown world and make them meet the social needs.
