Research On The Influence Of The Family Of Prototype Battery And PDEODE Teaching Strategy On The Modeling Of Primary Battery For Senior High School Freshmen

With the new curriculum reform further thorough,the newly released 2017 "the ordinary high school chemistry curriculum standard" proposed by chemical core literacy including "evidence reasoning and model recognition",emphasizes the students should have the empirical consciousness,to establish the model and use.Model method of chemical disciplines played an extremely important role in the development,in the chemistry teaching,the model can also help students to build knowledge theory model,to deepen the comprehension of knowledge and understanding,and the modeling process is a good time in the process of students experience the science inquiry,it can improve the students' innovation spirit and practice ability through modeling.The primary battery is an important part in high school chemistry course,How to choose suitable prototype and effective teaching strategy is one of the hotspots in high school chemistry teaching research.This research designed the uel cell prototype family and metal battery prototype family,revised Zhikang Zhang and Meihong Qiu 's electrochemical modeling ability test volume,and compiled the evaluation tools for primary battery academic achievement and emotional attitude questionnaire based on the literature review of chemical modeling,electrochemical modeling,POE strategy and PDEODE strategy.And then take 167 senior students as the research object,a quasi experimental study was designed to explore the influence of PDEODE teaching strategies and different battery prototypes on the students' modeling ability,academic achievement and emotional attitude.The results show that:1.Under the condition of using the same metal battery prototype family as learning materials,the PDEODE teaching strategy is more conducive to improving the students' battery modeling ability and academic achievement than the conventional teaching methods,and is also beneficial to the cultivation of students' emotional attitude.2.Under the condition of using PDEODE teaching strategy,the prototype of fuelcell prototype is more conducive to the improvement of students' academic achievement than the prototype of metal battery prototype;There is no significant difference in the influence of the student's battery modeling ability,but it has an influence on the thinking angle of the student modeling;However the model construction is based on the metal battery family is more conducive to the cultivation of students' affective attitude than the modeling of fuel cell family.
