"Chemical Reaction And Electric Energy" Based On Learning Advanced Theory Unit Teaching Design And Practice Research

In 2017,the Ministry of Education issued the ordinary high school curriculum standards in the learning the advantages of "core concept",and learning advanced the characteristics of the core concept as the center,also solved the traditional chemistry course teaching,memory only facts of knowledge lead to "cramming" teaching and "accept" learning,so as to realize the deep understanding of knowledge and the development of thinking ability,so in science education for learning advanced to carry out in-depth research and application is very necessary.Unit teaching is different from the traditional classroom fragmented knowledge learning,which has systematic and holistic characteristics,and is an effective way to cultivate students’ core literacy in chemistry.If the combination of learning advancement with unit teaching,it can give better play to the advantages of the two,vertically integrate knowledge,improve learning efficiency and develop students’ core literacy of chemistry.On the basis of sorting out and analyzing the relevant literature of"advanced learning" and "unit teaching",this study sorted out the research status of the two and the shortcomings of the current research,and determines the research topic.Under the background of learning advanced theory,guided by the theory of recent development area,using literature analysis,experimental research method,to "learning advanced" "unit teaching design" concept definition,and according to the chemical concept hierarchy found the "chemical reaction and electricity" core concept "unit" cell "" cell ",and conclude the core concept of the following five specific concepts,namely" cell working principle "" chemical power supply "" electrolytic pool "" electrolytic pool application "and" metal corrosion and protection ",and the"chemical reaction and electricity " unit unit teaching design and practice.The teaching of each specific concept corresponds to one class hour,and combined with the hierarchical model "experience(advanced starting point)--mapping--co-union--system--integration" proposed by Professor Yuying Guo,the teaching design and practice,and the unit is evaluated and reflected after practice.Through teaching practice,the following conclusions are obtained:(1)the unit learning framework of "chemical reaction and electric energy" is reasonable and superior;(2)high school chemistry unit teaching,it can promote the improvement of students ’academic performance,and promote students’ thinking level to a higher level;(3)compared with traditional teaching,advanced unit teaching provides teachers with paradigm reference and puts forward higher requirements for teachers’ ability level.
