Optimizing The Practice Research Of Newton's Law Of Motion In High School Physics

Newton's laws of mation lay the foundation for classical mechanics.They are also the important and difficult points during the learning process of high school physics,so they are often seen in the college entrance exam every year.In fact,there are so many practical applications and play very important roles in the learning process of kinematics,power and energy.And they are beneficial to student's emotional and thinking pattern.However,I have found that there exist so many problems with this part by collecting and analyzing the exam results of our students in 2017,by talking about this knowledge with my students and reflecting on my teaching.Firstly,students lack motivation and are not so interested in it.What's worse,students lack the abilities of innovative thinking,imaginal thinking,logical thinking and reading ability.Additionally,we teachers sometimes ignore the development of the ability of active exploration and innovation.That's to say,we can t always grasp the important and difficult points during the teaching process.As is known to us all,Neuton's laws of wation are very important,but less importance is attached to it,so we need improve this curront situation badly.Considering it,it comes to me that this part will be my subject study.I hope my research resuls will be beneficial to my later teaching job and all my peers.Three aspects about this subject study are as follows:Firstly,it's about the investigation and analysis of preconcepts and current learning situation of our students.By testing,questionaire study and interviewing methods,I have found that students are more likely to be affected by preconcepts when learning this part.Worse still,some students are not so good at comprehensive ability,modeling capability and reading ability.Secondly,try to optimize the strategy research about Neuten's laws of motion in high school physics.Specifically,with the guidance of coustructivism learning theory and Garaner's theory of multiple intelligences conceptual transformation theory,I finally have figured out four strategies about optimizing the teaching prosess of this part by reading the curriculum standards and examination outline of high school physics,along with some related articles carefully.That is,the strategy of transforming the wrong concepts,the strategy of the teaching of basic knowledge,the strategy of development of ability of thinking and innovation,the strategy of training the ability of reading comprehension.Thirdly,try to optimize the practical research of teaching of Newtan's laws of motion.During my teaching process,I insist on combining theory and practice,using the principle of educational scientific practice,comparing students in experimental class with students in common class,applying my new teaching strategies to my teaching process,at the same time,by controlling and operating related factors purposely,abserving students' before,after and during class performance,I have found that students in experimental class are more willing to involve in my class and have achived better academic achievements.So all of these have proved that my subject study has indeed a good effect on the leaving of Newten's laws of Motion and has played a positive role in improving the ability of my students.
