The Study Of Teaching Strategies Based On Cultivating "Evidence Reasoning And Model Cognition" Literacy Is Based On The Teaching Principle Of Chemical Reaction As An Example

With the advent of the digital age,the iterative updating of knowledge and information,for chemical disciplines,compared with the2003 edition of the high school chemistry curriculum standard,It is based on "ability" to cultivate students' related ability,the latest educational reform is the 2017 edition of high school chemistry curriculum standard,It is based on "accomplishment" to cultivate the students' chemistry discipline five core quality.The high school chemistry curriculum standard(2017 edition)is an important carrier to promote the formation and development of students' chemistry core literacy.The core accomplishment of chemistry discipline as the current educational theory research and front-line teachers pay attention to the hot direction,Among these five qualities,literacy 3 "evidence reasoning and model cognition" as a chemical subject core literacy' core of thinking,It contains the ideas and methods for students to form the chemistry discipline.If students can really have this quality,it will play a positive role in promoting their chemistry learning.Therefore,the teaching strategies to cultivate the quality of "evidential reasoning and model cognition" can promote the cultivation of students' core quality of chemistry.This paper mainly expands from the following parts:The first part is the introduction.By searching a large number of relevant literatures in CNKI for nearly 10 years,this paper introduces the writing background and research significance of the paper,the research status and related research results of evidential reasoning and model cognition at home and abroad have been made a literature review.The content and method of the study are expounded.There are very few researches on the teaching strategy of cultivating evidential reasoning and model cognition literacy by combining chemical reaction principle teaching in chemistry discipline at home and abroad,which provides an innovative point for this paper.The second part is related concepts and theoretical basis.In the study,we define the related concepts of core literacy,chemistry core literacy and so on,hoping to have a deep understanding of cultivating students' evidential reasoning and model cognitive literacy.Based on constructivism,meaningful learning,humanism and deep learning'relative educational theory,this paper carries out follow-up empirical research,which is the theoretical cornerstone of the research and has a fundamental significance for the research.The third part is a questionnaire survey on the current situation of high school students' evidence reasoning and model cognitive literacy in the teaching of chemical reaction principles.The results showed that the current students' literacy of Grade Two still needed to be improved,and the cultivation of students' this literacy was influenced by many factors.The fourth part is the teaching strategy research of cultivating students' evidential reasoning and model cognitive literacy.Based on the previous investigation and analysis of the current status of "evidential reasoning and model cognition" literacy of Grade Two students,the author puts forward six reasonable and effective teaching strategies,and selects the ordinary middle school in Guiyang during the internship,based on the application of these strategies in all aspects of the teaching process to cultivate students' evidential reasoning and model cognitive literacy,the empirical analysis is carried out.it is found that these strategies can promote students' evidential reasoning and model cognition literacy,enrich teachers' evidential reasoning and model cognition literacy,and provide model reference for teachers' teaching.The fifth part is the conclusion and prospect.The research of this paper provides teaching strategy guidance for the cultivation of evidence reasoning and model cognitive literacy,four conclusions are drawn on the results of the whole research process,the existing problems in this thesis are expounded.To make the core accomplishment take root requires the joint efforts of all colleagues and teachers.The cultivation of core accomplishment is a long process.We will sweat together and look forward to the wonderful development of chemistry discipline.
