Practical Research On Cultivating High School Students' Deep Learning Ability In Chemistry Through Digital Experiment

Deep learning refers to the learning that is active,inquisitive and understanding and closely related to reality.As an important starting point for deepening the curriculum reform of basic education and a practical approach for implementing the core quality of students’ development and curriculum standards of various disciplines,"Deep learning" project has become a hot spot and focus in the field of science education in the last decade of the 21 st century.The deep learning of chemistry course inevitably involves the deep understanding and application of the core content and thought methods of chemistry subject.By virtue of its advantages of providing quantitative evidence and visual data,digital experiment can effectively improve the breadth and depth of students’ learning and provide strong support for the development of students’ deep learning ability.The purpose of this paper is to explore whether digital experiments can promote students’ deep learning.Literature research method,questionnaire survey method,experimental research method and other research methods are combined for analysis and research.Firstly,through literature review,the concept,connotation and characteristics of deep learning and digital experiment,as well as the connotation and characteristics of chemistry deep learning are sorted out and integrated.On this basis,the research hotspot and development status of digital experiment and deep learning at home and abroad are summarized.Secondly,by conducting student questionnaire survey and teacher interview,we understand the current situation of deep learning in chemistry classroom of high school students and teachers’ cognition of digital experiment and deep learning.The main problems and causes are analyzed to provide reference for the design of subsequent digital experiments and teaching cases.Thirdly,the relevant contents of elements,compounds and chemical principles are selected,and two digital experiments are developed,"Exploring the reaction history of aluminum chloride and sodium hydroxide based on handheld technology" and "Exploring the critical p H of hydrogen evolution corrosion and oxygen absorption corrosion based on handheld technology",and corresponding teaching cases are designed.Finally,the digital experimental teaching cases designed are applied to classroom practice.The classroom status of students is evaluated from three dimensions of investment,meaning construction and problem solving mainly by means of classroom observation,and the deep learning level difference between the experimental class and the control class is compared and analyzed,so as to give feedback on the effect of digital experiment in promoting students’ deep learning.Through practical research,it is found that digital experiments can improve students’ deep learning ability,and the chemistry classroom based on digital experiments promotes students’ cognitive development and quality improvement.The author also reflected on the research process,and prospected the future research on digital experiments to promote students’ deep learning,so as to provide some references for other researchers.
