Research On Instructional Strategy Of Cultivating High School Students Interest In Physics Learning Based On Life

Physics as a basic subject in the field of nature,because of its strong logic and abstractness,the students in physics learning process there is a certain degree of difficulty,and leads to lower the students' interest in learning,difficult to develop the ability of autonomous learning,therefore,arousing students' interest in physics learning in teaching is very important.In Theory of Physical Learning edited by Mr.Yan Jinduo,the interests in physics learning are divided into four levels: intuitive interest,operational interest,causal interest and theoretical interest.When students' interest in each physics learning reaches a certain level,they can form a stable learning motivation.Reasonable use of life to carry out physics teaching not only conforms to the development of times and the requirements of curriculum standard,but also helps to cultivate and enhance students' interest in physics learning at four levels.This paper in view of the high school students' physics learning,Dewey's pragmatism theory,Tao Xingzhi's life education theory,constructivism theory as the theoretical basis,make full use of the life-oriented teaching,put forward four kinds of cultivating high school students of different levels of physical interest in learning instructional strategies: first,the optimization classroom import,cultivate the students' interest in intuition;Second,participate in the practice to cultivate students' interest in operation;Thirdly,to explore the law of things and cultivate students' interest in cause and effect;Fourthly,improve logical thinking and cultivate students' interest in theory.Select Free fall and Gravity Basic interaction and Stretch sections,according to the four instructional strategies to write teaching design and applied to the teaching practice,through the questionnaire investigation was carried out on the teaching practice class a pretest and posttest,comparative data and found that although the practice conditions,teaching design content,the teaching time and practice object sample are limited,we have put forward based on the life cultivation of high school students' physics learning interest the implementation of the teaching strategies for the cultivation of students' learning interest is effective,students' interest in the above four levels of physics learning has been improved.In addition,at the same time of pre-testing the teaching practice class,author also investigated some high school students' interest in physics.The results of the questionnaire of high school students' learning interest in physics designed by the author show that the Kronbach coefficient value is 0.823 and the KOM value is 0.833,which indicates that the questionnaire has good reliability and validity and the obtained data has certain reference value.In the pre-test of teaching,the average scores of students' intuitive interest,operational interest,causal interest and theoretical interest are 15.3462,13.0192,9.8654 and 8.6538 respectively.In the post-test of teaching,the average scores of students' four learning interests are respectively 16.1346,14.6538,12.2115 and 11.7115,all of which have been improved.It can be seen that the instructional strategy of cultivating high school students' interest in physics learning based on life proposed by the author can improve students' interest level in physics learning to a certain extent.
