The Cognitive Study Of High School Students' The Chemical Reaction Principle On The Basics Of Hand—Held Technology

With 21st century school quality education reform and the pace of the rapid development of information technology on the basis of the traditional teaching to join the experiment link has slowly in the high school teaching widely popular,especially with hand-held technology on the basis of the experimental teaching is more valued,however,we need to pay attention to is in the link to join hand-held technology and traditional experiment teaching and what change?What are the advantages and disadvantages of each?What can be changed from a student's perspective?The experimental teaching based on hand-held technology is also favored by many educators.What are the effects of the two on students' cognitive ability?So what are the advantages and disadvantages of hand-held technology compared with conventional experiments?This article includes the following five chapters:The first chapter is an introduction,which introduces the background of this research and expounds the problems to be solved in this study.The second chapter is the theoretical basis,and the cognitive theory applied in this study is introduced.The third chapter is about the design of research plan and tools,and introduces the methods,objects and specific implementation ideas of this research.The fourth chapter is the main part of the paper,the comparative study on the cognitive ability of the students and the traditional experiments,the two specific cases,and the comparison and analysis of two classes using hand-held technical instruments and traditional experimental instruments from different angles.The fifth chapter is the conclusion and analysis of cognitive learning theory based on hand-held technology.Based on the results of the analysis,we draw the conclusion and introduce feasible suggestions.Implementing contrastive teaching,we reach to the following conclusions after the research.(1)It shows that there's no obvious difference between two kinds of teaching patterns.However,the experimental class is in a dominant position in the comprehension of abstract issues.(2)The Hand-held Technology of Image display function enhances student's interest in chemistry learning.(3)The Standard drawing function of Image display function improves the ability of dealing with image problems.(4)Image display function has an apparent effect in girls' conception learning,especially for those have difficulty in learning,but makes little difference in excellent girls.
