Research And Practice Of Middle School Chemistry Teaching Based On Evidence Reasoning

With the Ministry of Education officially promulgating the Chemistry Curriculum Standards for General High Schools(2017 Edition),the core chemistry literacy is becoming more and more familiar.Core literacy plays an important role in the reform of new curriculum education and teaching,among which "evidential reasoning",as an important part of core literacy,has mushroomed in educational research and educators' research in recent years.Integrating evidential reasoning into chemistry classroom teaching can cultivate students' evidential awareness and reasoning ability,incubate students' key qualities in the development of cognitive activities and solving related problems,and is also one of the important ways to cultivate core literacy.Based on theoretical analysis and practical teaching,around the middle school chemistry teaching research practices based on evidence reasoning,after studying the relevant literature,the author to practice school to teach two classes as object,the first questionnaire survey was conducted for the local teachers,found that most of the teachers of core literacy has certain understanding,but for the core literacy in teaching and role did not have too much involved in the application.Then we conducted an evidence-based reasoning investigation on the students,and found that the evidence-based reasoning ability of the students was relatively weak,and the core quality needed to be further improved.On this basis,the author designed the evidence-based reasoning teaching process,aiming at training students to collect evidence,screening evidence for accurate and effective reasoning ability,and carried on the teaching practice in the experimental class.After the teaching practice,we conducted a post-test and interview for the two classes.Through the analysis of the results,the following conclusions were drawn :(1)Teaching based on evidential reasoning helps to enhance students' interest in learning.(2)Teaching based on evidential reasoning is conducive to improving students' academic performance.(3)Teaching based on evidential reasoning helps to improve students' evidential reasoning literacy.(4)Teaching based on evidential reasoning helps to change students' learning styles.
