Survey Research On Situation Of Scientific Inquiry Of Electrical Experiments For Senior High School Students

With the further advancement of ordinary high school education curriculum reform,the value of education has gradually shifted from a three-dimensional goal to a key competences perspective.The key competences of physics is the essential character and key ability that students gradually form in the course of receiving physics education.It is embodied in four aspects: physical concept,scientific thinking,scientific inquiry,scientific attitude and responsibility.Scientific inquiry is an important part of the key competences of physics.It is not only the basic teaching content of senior high school physics courses,but also an important teaching method.However,it is undeniable that the phenomenon of scientific inquiry in the current general high school physics teachings is ubiquitous.Putting key competences requirements on the ground requires finding problems from the status quo and further improving and strengthening them.This research conducts questionnaires and interview outline design from the perspective of key competences of physics subjects.It conducts a questionnaire survey of the state of electrical experiments in senior high school students and uses SPSS19.0 to process the data.The survey results show that the Cronbach's Alpha ?coefficient of the questionnaire is 0.899.The validity KMO value is 0.887,indicating that the questionnaire has good reliability and validity,and can accurately reflect the status quo and problems of senior high school students' electrical experiment scientific inquiry.The study finds that the problems existing in the scientific research of electrical experiments among ordinary senior high school students mainly include:students cannot flexibly design experiments,can't independently match and select experimental equipment,have difficulty in regulating the operation of experimental instruments,and have difficulties in data collection and processing.Larger.The reason is mainly due to the lack of organic links between experiments and the teaching of concept laws,the lack of independent thinking and practice space for students,and the low rate of experimental opening in senior high school,and the lack of guidance for students on data collection and processing.Combining with the problems found in the research and related causes,aiming at ordinary high school electricity experiments,this study proposes that teachers guide students to design their own experiments,use interest-oriented self-made low-cost experimental instruments,strengthen data collection and processing methods,and use computers for data processing.Measures such as applications have,to a certain extent and within a certain range,increased the interest of senior high school students in autonomous scientific inquiry,as well as the actual processes and implementation effects of scientific inquiry,and promote the better development of students 'scientific inquiry capabilities.
