Research On Teaching Strategies And Application Of Chemical Elements Compounds In Senior High School To Promote Deep Learning

Deep learning is an effective way to develop the core literacy of students' chemistry disciplines.It is of great significance to promote the transformation of students' learning style and promote the smooth implementation of basic education chemistry curriculum reform.As an important teaching content of high school chemistry,elemental compound knowledge is an important carrier for the development of students' core literacy.Therefore,the deep learning of students' knowledge of elemental compounds is an inevitable requirement of the current chemistry curriculum reform.On the basis of reviewing the existing researches on deep learning at home and abroad,the thesis defines the concepts of deep learning and elemental compounds.Under the guidance of the theory of cognitive flexibility and metacognition theory,based on the analysis of deep learning and the knowledge characteristics of elemental compounds,the teaching characteristics of high school chemical element compounds that promote deep learning are summarized.Based on the understanding of the teaching characteristics of high school chemical compounds that promote deep learning,using the methods of classroom observation and text analysis,the typical inorganic element compound "Sulfur and its compounds" and the typical organic element compound "Ethanol" are taken as examples.The teaching perspective and the perspective of student learning have analyzed the problems in the teaching of high school chemical element compounds,and obtained the status quo of high school chemical element compound teaching.Based on this,the problems in the teaching of high school chemical element compounds,around the components of the teaching system,from the design of teaching objectives,the organization of teaching content,the creation of problem situations,the design of learning activities,teaching evaluation and reflection The teaching strategies of high school chemical element compounds for deep learning are proposed,including: establishing the teaching objectives of higher-order thinking development based on knowledge value analysis;rationally organizing structured teaching contents;creating real and thoughtful problem situations;learning activities Designed to promote the transformation of students' learning styles;establish acontinuous and diverse feedback evaluation method.Finally,the proposed high school chemical element compound teaching strategy is applied to the specific teaching design,and the teaching design is used to explain how to apply these teaching strategies in practical teaching.In view of the fact that the knowledge of chemical element compounds in high school can be divided into two parts: inorganic element compounds and organic element compounds,and deep learning advocates the subject of unit learning,this part separately carries out the unit teaching design and typical of the typical inorganic element compound "Sulfur and its compounds".The class teaching design of the organic element compound "Ethanol".Each teaching design is carried out in terms of teaching content analysis,academic analysis,teaching objectives,teaching concepts,teaching process,and teaching reflection,in order to fully reflect the application of elemental compound teaching strategies to promote deep learning in practical teaching.
