Practical Research On Percolating The Thought Of Combination Of Numbers And Shape Into Chemistry Teaching Of Senior High School By Hand-held Technology

With the development of the thought of combination of number and shape,its research in the field of chemistry teaching has gradually surged.The thought of combination of number and shape is a thought that to solve problems by combining abstract mathematical language with intuitive images.Number and shape are two basic research object,which can convert mutually under certain conditions.This research takes the hand-held technology as the main tools and put forward the teaching strategy of the thought of number and shape to percolate into Chemistry teaching with the help of hand-held technology And select suitable cases to carry out the practical research on this basis,looking forward to enriching the research on the application of combination of number and shape thought by the suggestions that put forward in this research.Meanwhile,to help more and more students understand and grasp the knowledge learned more thoroughly and cultivate students’ core quality of evidential reasoning.First of all,part of theory.After consulting a large number of documents and summarizing relevant research at home and abroad by using the method of literature research,this study investigates the current situation of percolating the thought of combination of number and shape into chemistry teaching to practice in middle schools under the guidance of schema theory,constructivism theory and representation theory,and puts forward the teaching strategy of percolating the thought of combination of number and shape into chemistry teaching in high schools by means of hand-held technology,"Teachers change their concepts,establish the teaching consciousness of combination of number and shape,study textbooks to select typical cases,guide students to analyze the quantitative relationship and draw curve images by means of hand-held technology,and finally realize the transfer and application of knowledge" On this basis,the paper puts forward the teaching process,the principle of strategy application and the evaluation method of strategy application effect.Second,part of practice.According to PEP senior high school chemistry elective 4 Principles of Chemical Reaction,three teaching cases,"Determination of Chemical Reaction Rate","Factors Affecting Chemical Reaction Rate" and "Influence of Concentration on chemical equilibrium",were selected in this study for practice in a middle school in Ningxia.The students and teachers involved in the practice were investigated by questionnaire and interview.After analyzing and summarizing the practical results,some suggestions were put forward on how to percolate the idea of combining numbers with shapes into chemistry teaching.It is indicated in the research that the thought of combination of number and shape can be effectively percolated into high school chemistry teaching by hand-held technology,and the application of hand-held technology can stimulate students’ interest in learning and make students actively participate in classroom sessions;Percolating the thought of combination of number and shape into high school chemistry teaching with the help of hand-held technology can improve students’ ability to collect evidence,deduce evidence,distinguish evidence and apply evidence,and cultivate students’ core quality of evidential reasoning;Percolating the thought of combination of numbers and shapes into high school chemistry teaching with the help of hand-held technology can help students understand and master what they have learned.Therefore,the teaching strategy of percolating the thought of combination of numbers and shapes into high school chemistry teaching with the help of hand-held technology constructed in this study is feasible and has positive enlightenment and reference for front-line teachers.
