Study On The Spiral Model Of Chemistry Knowledge Learning In Middle School Under The Guidance Of SECI

In the age of knowledge development,knowledge is being transformed into the technology around us through the localization of people,and the most important form of knowledge transmission is in the classroom,the learning of knowledge is produced in the communication between teachers and students.And as the university says,"to know in conforming","conforming" is to explore things to achieve the principle of things,the law of understanding.So,in the chemistry class,what form does knowledge pass between teachers and students?First of all,there are two basic forms of knowledge-tacit knowledge,formal knowledge.Secondly,on the process of knowledge creation,in the SECI spiral model of knowledge creation proposed by Japanese scholar Nonaka,it includes four processes of "co-","externalization","uniting" and "internalization"(hereinafter referred to as "Four Modernizations").In the classroom,on the one hand,these two forms of knowledge in the proportion of teachers and students are different,and in the "Four Modernizations" process,tacit knowledge and formal knowledge can occur to varying degrees of transformation.On the other hand,in the SECI model,knowledge is rising in the form of a spiral,like the three-dimensional trapezoidal in the geometry,so the bottom radius of the trapezoidal can be used to represent the knowledge base(that is,the transverse radius of the spiral),the high trapezoidal expression of the depth of knowledge(that is,the longitudinal height of the spiral)In this way,with the occurrence of each chemical knowledge learning,the knowledge base is constantly expanding,the depth of knowledge is constantly rising,we should first analyze the relationship between knowledge base and knowledge depth.At the same time,because knowledge learning is a process of mutual influence between teachers and students,students ' knowledge spiral will affect teachers to produce a very small knowledge spiral,so the actual existence of the spiral should be double helix.However,in teaching,because the probability of teacher knowledge spiral is very small,negligible,the knowledge spiral is mainly the knowledge spiral of students.Under the guidance of the above theoretical hypothesis,the main contents of this thesis are as follows: first,establish the SECI spiral model of chemistry knowledge learning combined with teachers,students and teaching environment.Secondly,using the model and its "four Modernizations" operation process,this paper analyzes the influencing factors of students ' chemical knowledge learning,classifies them and calculates various factors,and then establishes the mathematical model of SECI chemistry knowledge learning based on knowledge base and knowledge depth,and then uses the software to simulate the various parameters of the model,Use this to verify the effect of the model.Finally,the SECI spiral model of chemical knowledge learning is used to design the learning process of chemical knowledge in order to improve the efficiency of chemical knowledge learning effectively and to contribute to the further improvement of chemistry teaching system,so as to contribute to the better development of chemistry teaching.
