The Application Of Hand-held Technology In Chemistry Experiment Teaching Research

As a new kind of experimental teaching auxiliary equipment,hand-held technology experiment has the characteristics of novel form,simple operation,strong exploration,rich content,convenient and fast data processing,etc.,which provides new vitality and vitality for the reform of chemical experiment teaching.Under the guidance of constructivism theory,information processing learning theory,and multiple intelligence theory,this study distributes questionnaires to chemistry normal students in school to understand the application status and development prospects of hand-held technology.Teaching strategies applied to chemistry classrooms,and suggestions for carrying out hand-held technology experiments.This study is classified according to basic concept,simple application and life transfer.Two corresponding experiments are designed respectively,with a total of 6experimental schemes.Three typical experiments are selected from them.Combined with different teaching modes,several teaching designs and teaching cases of chemical experiment teaching using hand-held technology are put forward from all aspects of the teaching process.The teaching case of hand-held technology experiment is applied to teaching practice,and the training and discussion of hand-held technology experiment are carried out for normal students,which has achieved good results.Through the discussion on the training of hand-held technology and case teaching of normal chemistry students,the following conclusions can be drawn:(1)Handheld technology experiment plays a positive role in strengthening classroom interactive teaching and improving the classroom teaching effect of chemical experiment;(2)Handheld technology experiment is conducive to inquiry experimental teaching and can deepen students’ understanding of experimental projects;(3)Strengthening the discussion on the handheld technology experiment project of chemistry normal students in pre service training will help to improve the professional ability of normal students and promote the professional development of teachers;(4)With the improvement of software and hardware conditions,handheld technology,as a teaching means and tool,is widely used in middle school chemistry experiment teaching,which has a certain practical feasibility.Under the background of educational informatization and educational modernization,normal education should keep pace with the times.As a new teaching auxiliary means,hand-held technology plays a very important role in the training and professional development of chemistry teachers.In order to promote more chemistry teachers to further understand hand-held technology experiment,apply it in future practical activities,and improve the professional development level of teachers,this study applies hand-held technology to the teaching research of chemistry experiment,and gives reference cases through teaching practice,...
