Reverse Teaching Design Under The Core Quality Of "Evidence Reasoning And Model Cognition"

At present,international and domestic research on the overall teaching of units is in full swing,and many teachers often start with teaching materials,favorite methods and traditional activities when designing teaching units,rather than with the focus-such as content standards and understanding such as target results.There are two misunderstandings in teaching,one is purposeless indoctrination,teachers tend to take the content of teaching materials as the task that must be completed in teaching,a large amount of scattered knowledge is insufficient for students,in order to make students’ ability in the field of inquiry develop,students must pursue understanding learning;The second misconception is isolated activities,where learners only feel fun from the activities and do not appreciate the meaning behind the activities.The comprehension-based reverse unit teaching design proposed by Wiggins and Mc Teiger advocates reversing the original teaching habits,starting with the results,and then determining whether students have achieved the desired goals by determining the necessary evidence.Actively guide teachers to think about what the purpose of learning is,how to evaluate what students have achieved a certain goal,and how to design activities before teaching and learning,so that students can deeply understand the deep meaning behind this purpose to design teaching.Under the background of the globalization of literacy,each discipline puts forward the corresponding core literacy according to its own characteristics,and improves the education curriculum system based on students’ core literacy,"evidence reasoning and model cognition" is the core thinking in the core literacy of chemistry,which is of great help to students to build a framework system of knowledge,help students deeply understand knowledge,improve comprehensive ability and literacy level and transfer ability.Based on reading a large number of literature,this paper determines the feasibility of combining reverse teaching with core literacy,and takes "The Amount of Matter" as an example to carry out practice.This research content is divided into six parts,based on the domestic and foreign research background of core literacy and reverse teaching design,the research status of "material quantity" teaching design,and the use of questionnaire surveys,teaching experiments and other methods,focusing on the teaching practice of "material quantity".Through the collation and analysis of data,the following conclusions are obtained: 1.The reverse teaching design based on the core literacy of "evidence reasoning and model cognition" has a certain role in promoting students’ learning,which is conducive to realizing the transfer and application of knowledge,cultivating students’ ability of evidence reasoning and model cognition,and constructing a knowledge thinking framework.2.Build a model of "evaluation first,start with the end",and can be applied to other class hours.3.Based on the core literacy of "evidence reasoning and model cognition",diversified evaluation methods such as model construction and interview in reverse teaching design can improve the effectiveness of the classroom,improve the teaching effect,and help the professional cultivation of teachers themselves.
