Design And Practice Of Mobile Phone Charger Assisted Electrochemical Teaching Based On The Cross-discipline

In middle school chemistry teaching,interdisciplinary emphasis emphasizes that the content of chemistry teaching should tend to be integrated and diversified,and advocates the integration of multi-field and multi-disciplinary qualities.This research incorporates the crossdisciplinary concept into the teaching of electrochemical experiments,designing an electrochemical experiment device with a small amount of reagents,obvious experimental phenomena,and easy to promote,which is conducive to improving students 'learning ability and problem solving ability,and developing students' creativity in practice.The mobile phone charger assisted in electrochemical teaching with penetrating crossdisciplinary concepts is expected to provide new ideas for the reform of chemistry experiment teaching and provide a new way to implement innovative education and cultivate innovative talents.This research is divided into four parts: The first part summarizes the interdisciplinary teaching research and its application in middle school teaching and the status of electrochemical experiment teaching,etc.,to provide a theoretical basis for subsequent research.The second part is to design the electrochemical experiment.According to the design types of middle school electrochemical experiments summarized in the first part,electrolysis,electroplating,and electrophoresis experiments were selected as the content of innovative experimental design and integrated with mobile phone chargers to design daily and miniaturized electrochemical experimental devices.At the same time,by investigating the influence of experimental operating conditions on electrochemical phenomena,the experimental device is optimized to provide an operating platform for electrochemical experiments to enter the classroom.The third part is to design electrochemical teaching cases and apply them to the classroom.The teaching content is to elect the relevant knowledge of electrolysis experiment,electroplating experiment and electrophoresis experiment in compulsory one in Chapter IV of Chapter 4 "Electrochemical Basics".The interdisciplinary knowledge and skills of physics,biology and mathematics are combined with chemistry teaching.The quasi-experimental research method was used to carry out electrochemical innovation experiment teaching and routine teaching to the students in the experimental class and the control class,and compare the teaching effects of the two after the experiment.The fourth part is based on the test results of students before and after testing,inferring that the mobile phone charger-assisted electrochemical experiment teaching that penetrates interdisciplinary subjects is feasible,can improve the classroom teaching effect,and is helpful to cultivate students' learning ability,problem solving ability and creativity.
