An Experimental Study On The Influence Of "Designing Experiment And Making Plan" On The Inquiry Ability Of Senior High School Students

With the gradual development of the new curriculum reform,the reform of physics teaching is also in constant innovation.The purpose of education is no longer simply to teach students knowledge.Education and teaching have gradually changed into the main way of moral cultivation,service selection and teaching guidance.In the teaching of physics,our aim is to hope that students can master the relevant ability of physics,and gradually form their due scientific attitude and social responsibility.In December 2017,the Ministry of Education issued the physics curriculum standard for senior high school(2017 Edition),which puts forward a new concept-Physics core literacy,which is composed of four elements: physical concept,scientific thinking,scientific inquiry,scientific attitude and responsibility.It is the key ability and necessity for students to adapt to the needs of personal life-long development and social development in the process of accepting physics educationPrepare character.If the concept of physics is the carrier of the formation of the core quality of physics,then scientific exploration is the main way of the formation of the quality of physics.The research of educational psychology shows that the process of students' mastering knowledge is a combination of perceptual knowledge and rational knowledge.Students gain direct experience after experiencing it in person with their own body,and the process of scientific exploration is also an activity of "I".Scientific exploration makes it easier for students to understand and master relevant physical concepts,and also cultivates students'scientific thinking abilityIt has a certain influence.It can be seen that scientific inquiry is particularly important for the cultivation of students'core competence in physics.Through interviews with teachers and their own teaching students'homework feedback,the author finds that students can't fully and skillfully use several links of scientific inquiry.For this reason,I set up a questionnaire for several links of the elements of "scientific inquiry",taking the students of my school as the research object.The results show that 65.9% of the students have problems in the link of "designing experiments and making plans".And this link is the main link of scientific inquiry,is also an essential important link,will directly affect the enthusiasm of students for scientific inquiry,and will also directly affect the level of students'scientific inquiry ability.Therefore,it is urgent to break through the difficulties in this link.The author looked up the relevant literature again,and found that the predecessors studied the teaching strategies of "designing experiments and making plans" link,but the research on which stage the students have reached in this link,and which steps are difficult for different types of experimental students in this link,and how much influence the scientific research ability of students has not been found.Based on this,and combined with the teaching situation of my teaching school,this paper puts forward the research purpose and significance.This research mainly uses the literature method,the paper and pen test method,the questionnaire method,the interview method and the speculative method.Through the comprehensive application of the above-mentioned methods,the problems in the links of "designing experiments and making plans" for students are thoroughly understood,and the corresponding countermeasures are put forward.Based on the framework of "suggestions on the framework of the performance of the physical subject based on the core literacy" in the "Research on the ability of the physical subject based on the core literacy",the author divides the high school physical science inquiry activities into three types: basic understanding type,application practice type and innovation inquiry type.This paper divides the "design experiment and plan" into several stages to design the questionnaire,taking the students of my school as the research object,and makes a research on the performance of scientific inquiry ability in the "design experiment and plan".The results are as follows:(1)Basic understanding experiment.About basic understanding experiment design,more than 80% of the students can design a feasible and complete experiment scheme,but some of the experiment schemes are still a little inadequate,not paying much attention to details.While about 3% of the students can only make clear the purpose of exploration and find out the principle of the experiment;about 5% of the students can analyze and determine which physical quantities need to be measured in the experiment,and there are several methods to measure these physical quantities,but it is not clear which method should be selected properly;about 12% of the students can make clear the physical quantities to be measured and choose the measurement method,so as to determine the selection of experimental instruments.(2)Applied practical experiment.About the practical experiment design,only 42% of the students can design the experiment scheme with strong theoretical feasibility;12% of the students can only make clear the design intention;17% of the students can analyze the physical knowledge related to the design intention and the problems that need to be solved in this design,but do not know the solution;16% of the students can make clear thisAbout 13% of the students can choose the appropriate method and determine the experimental equipment,but they don't know how to assemble the experimental equipment.(3)Innovative and exploratory experiments.About the innovative inquiry experiment design,only 36% of the students can design the experiment scheme with strong theoretical feasibility;about 34% of the students can only make clear the purpose of inquiry and know which branch of physics should be used;about 19% of the students can analyze the measured physical quantity and think about its solution,but can not choose the appropriate method;about 11% of the students can chooseSelect the appropriate method and measuring instrument,but the details are not clear.The purpose of this paper is to study the influence of design experiment and scheme making on the scientific inquiry ability of senior high school students.Only by breaking through this difficulty,can students participate in it,be willing to take the initiative to experience and try,learn to think independently,make scientific inquiry more complete,and promote students'interest and enthusiasm in physics learningIt can also stimulate students'life vitality and promote their life growth.
