Research On Teaching Design And Practice Of Chemical Element Compounds In Senior High School Based On "5E" Teaching Mode

In order to carry out the general high school education idea,it is particularly important to break the original teaching mode and explore and construct a new teaching mode.The series of "learning rings" of "5E" teaching mode,namely Engage,Explore,Explain,Elaborate and Evaluate,focus on promoting students' cognitive development level and problem-solving ability.It can effectively break through the teaching dilemma in the traditional classroom and is conducive to the implementation of the new curriculum standards and the improvement of teachers' education and teaching guidance ability."5E" teaching mode,as a new educational method,conforms to the basic concept of "literacy orientation" chemistry classroom teaching of the new curriculum standard,and also provides important reference and reference value for the teaching reform of the knowledge of elemental compounds.At the same time,the knowledge of elemental compounds is also the root of learning other knowledge modules.In the five hierarchical gradients of "5E" teaching mode,students learn to independently construct the knowledge network of elemental compounds,which plays a decisive role in improving students' self-accomplishment and self-development ability.Comb first of all,the deep analysis of the new curriculum standard and the content of the new textbook compulsory module,on the basis of element compounds the status of knowledge in the teaching material and the content of the new standard for the module knowledge and academic requirements,combing the relevant literature,refined to be support for the theoretical basis and based on the "5E" teaching pattern of high school chemistry element compound teaching design principles.On the basis of understanding students' learning disabilities,this paper analyzes and summarizes the difficulties of the module knowledge of elements and compounds in practical teaching,and at the same time defines the core concepts of this study and clarifies the core content.Make clear the learning characteristics of students in "5E" teaching mode,and try to explore the application of the core concept of "5E" teaching mode in the teaching of specific knowledge modules of elements and compounds,so as to construct appropriate teaching strategies for experiments.Secondly,set up based on the "5E" series "learning" teaching model and corresponding teaching strategy to carry on the organic fusion,according to the characteristics of element compounds content find out the ways to design the teaching main line,to extract the teaching of plate around the core knowledge and ideas to establish complete with the five ring "learning" guidance elements compound model structure of the knowledge content learning,The teaching design of typical cases is carried out,and the designed teaching cases are used in classroom practice.Select a senior high school grade one students as the research object,setting up a experimental classes,the experimental classes before the mid-term grades as a measurement,after the final grade as a test,this paper compares and analyzes analysis before and after using the "5E" teaching mode in the implementation of the students' learning status change and related problems,and targeted Suggestions on problems are: Suggestions on teaching case design stage;Suggestions on the teaching stage of classroom organization;Case implementation of reflection phase recommendations.Finally,the innovation of this study is to design the framework and key points of the "5E" teaching mode in the teaching implementation stage based on the "5E" teaching mode,according to the requirements of the new curriculum standard,literacy evaluation system,students' cognitive development level,existing prerequisite knowledge and so on.On this basis,the teaching process framework and quantitative evaluation table of students' learning activities based on "5E" teaching mode are designed.In the implementation process,students' learning behavior and comprehensive quality development are evaluated by referring to the evaluation standards,and the classroom teaching design concept based on the "5E" teaching mode is deeply analyzed and concluded: it embodies the teacher-led and student-centered concept;Reflect the concept of taking questions as the guidance and taking inquiry as the center;It embodies the concept of evaluation as a summary and practicality as the foundation.At the same time,the basic principles of teaching design of chemical elements and compounds in senior high school based on "5E" teaching mode are extracted: the student-centered principle;Principle of inquiry;Creative principle;Comprehensibility principle;The principle of evaluation.Finally,the feasibility and effectiveness of the application of "5E" teaching mode in the classroom teaching of knowledge module of elements and compounds in senior high schools are verified,and the learning advantages of "5E" teaching mode are found: it can promote students' deep learning and form higher-order thinking;It can stimulate students' drive and enhance their learning initiative.It can cultivate students' ability of evidentiary reasoning and self-structured knowledge;It can promote students' knowledge transfer and understanding and application ability;It can effectively improve students' self-cognition ability.
