Research On The Teaching Strategy Of Chemistry Experiment In Senior High School Based On Scientific Research And Innovative Consciousness

The chemistry curriculum standard of senior high school(2017 Edition)emphasizes that the core quality of chemistry discipline in senior high school includes five dimensions,among which the "scientific exploration and innovation awareness" dimension attaches importance to the cultivation of students' practical ability.Chemical experiment is an important way to cultivate students' ability of scientific inquiry,unity and cooperation,and innovative consciousness.In this thesis,I comprehended the research background and research status of this topic by consulting the literature,sorted out the relevant concept connotation and theoretical basis,realized the significance and task of the research,and determined the research ideas and research methods.According to the requirements of the new curriculum standard for senior high school students' scientific exploration and innovation awareness,I designed two questionnaires to understand the current situation of chemistry experiment teaching in senior high school and the current situation of scientific inquiry ability and innovation consciousness of Senior One Students.Statistical analysis shows that the current situation of chemical experiment teaching makes students lack enough practice opportunities,and students' scientific exploration ability and innovation consciousness cannot meet the requirements of the new curriculum standard,which needs further development.On the basis of the above research,combined with the relevant contents of pedagogy,I put forward the corresponding teaching strategies:(1)The teaching strategy of cultivating the ability of putting forward questions and hypotheses: By using social current events,reviewing old knowledge,demonstrating chemical experiments and other ways to create a real and effective problem situation,students' curiosity and curiosity can be aroused,and students' problem awareness can be cultivated.(2)The teaching strategy of training the ability of designing experiment scheme and collecting evidence: Give full play to the role of chemical experiment,carry out chemical experiment teaching through group experiment or teacher demonstration experiment,and provide more opportunities for students to operate the experiment.(3)Teaching strategies for problem presentation,cooperation and communication: Guide students to systematically and clearly present experimental phenomena and data by means of charts and tables;Make the students clear about the division of labor in the experiment and try to complete the experiment part they need to undertake;Train students to be good at expressing their own views and listening to others' views.(4)The teaching strategy of cultivating the ability of innovation consciousness: Encourage students to use information to make a variety of possible assumptions;Guide students to think about the design of experimental scheme and the selection of experimental device from multiple perspectives;Play the role of students' divergent thinking.In the process of practice,I studied the students through classroom observation and analyzed and summarized the implementation of teaching design after class.Through the analysis,I found that the implementation of the corresponding teaching strategies of this study,students were more active in the classroom,teaching activities were carried out smoothly.However,the improvement of students' scientific exploration ability and innovation consciousness is a long-term development process,which needs more detailed and systematic research in the future.
