Research On Teaching Practice Of Promoting "Evidence Reasoning" Subject Quality With Infrared Thermal Imaging Technology

"Evidence-based reasoning",as a higher-order way of thinking,is the core method of chemistry literacy.As an important carrier of chemistry,experiment plays a key part in disseminating students' chemical knowledge,cultivating their scientific methods,and inspiring their researchful minds.But there are still problems such as single choice of experimental method and insufficient implementation of the core literacy of the discipline.With the update and iteration of science and technology,the introduction of new technologies into the classroom has become a reality.And technology-enabled education and teaching innovation will also become an irresistible tendency in the progress of education in the new era.Based on the background,In this paper,based on infrared thermal imaging technology,the development of infrared thermal imaging experiments is carried out.And the experimental activity design and educational practice research on training students' "evidence reasoning" discipline based on infrared thermal imaging technology is carried out.Mainly include the following:The author conducted literature research on the research of thermal imaging technology at home and abroad and its application in education and teaching.And established the research content,research purpose and method.Select three modules of "reaction of barium hydroxide and ammonium chloride,neutralization reaction" and "chemical energy and electrical energy" to develop and design infrared thermal imaging experiments,including experimental design principles,design process,experimental result analysis,and educational function value.The experimental results show that infrared thermal imaging technology has advantages in greening the dosage of drugs,visualizing and digitizing the heat changes in the reaction process,and providing students with new observation perspectives and thinking methods.Undertake the experimental development results of infrared thermal imaging,and carried out experimental activities based on infrared thermal imaging technology to promote the core literacy of students' "evidence reasoning" for the three modules of "interconversion of chemical energy and thermal energy,neutralization reaction" and "chemical energy and electrical energy".design.In order to examine the effect of the experimental activity design.Two classes of a high school in Kunming City were chosen for a five-month praxis.The results of practical research show that the application of infrared thermal imaging technology to the teaching of chemistry experiments has a certain role in promoting students' "evidence reasoning" discipline literacy.This paper is an attempt and preliminary exploration of the application of infrared thermal imaging technology in chemistry experiment teaching,which has achieved the expected research goals,and can provide a basis and reference for subsequent infrared thermal imaging experimental research and front-line teachers' teaching.
