The Study On The Application Of Experimental Video Presentation In School-based Materials For Students’ Development In High School Chemistry Experiments

Chemistry is an experimental science,and experimental teaching is the core of chemistry teaching.Because of this,experiments and experimental teaching has become the focus of concern to the majority of teachers,but with the negative influence of the "scores only" caused by the College Entrance Examination,chemistry experiment teaching in China has confronted a fallacy-to replace "doing" with "saying","exercising" with "drawing","reciting" with "practicing" It is true that students who rely on reciting the experiments can really get a certain score in the College Entrance Examination,but the depth of learning ability,practical ability,creative ability is conceivable.In view of this situation,we need to explore how to improve the students’ experimental effect,making the students experience the fun of science,and to achieve all-round development.In this thesis,the author aims at the development of students,through the edition of the school-based teaching materials,and apply the research results to the practice of chemical experiment teaching.According to the design of all kinds of chemical experiment teaching modes and the number of school planning,the author reasonably selects the experimental teaching modes of presentation,using mobile phone,video editing software such as multimedia technology,and conveys several typical experiments from the knowledge of chemical elements through experiments by students and several video clips,and playback of reflective learning,to break some of the difficult points.Through this application,the teachers have changed their attitude towards the experimental teaching on students’ cognition,expanded their theoretical knowledge,and developed their teaching ability.In addition,it’s also stimulated the creative thinking and the potential of students,promoting their all-round development.The students’ interest in learning chemistry,the ability to carry out the operation,and the chemistry learning results are also improved.This thesis is divided into the following five parts.The first part mainly discusses the background of the topic,the question,the research purpose,the method and the present situation of the chemical experiment.The second part mainly discusses the theoretical basis of this study.The third part is mainly about the development of school-based teaching materials and the application of experimental video.In the fourth part,through the analysis of the students’ questionnaires and the students’scores,it is concluded that this study can improve students’ achievement,stimulate students’ interest and develop students’ ability.The last part is the conclusion and reflection of this study.
