| With the increasing emphasis on scientific demonstration in China’s education,the number of argumentative teaching and research focusing on the cultivation of students’ argumentation ability presents a trend of increasing.Compared with other curriculum types,the current research on scientific demonstration problem solving teaching practice is not enough.Under this background,it is an inevitable move to construct the corresponding model and integrate scientific demonstration into physics problem solving teaching to conform to the current teaching reform trend.In the first chapter is the introduction of this research and second chapter,the relevant concepts such as prophase work,first of all,based on the definition and the requirement of scientific reasoning in the curriculum standard,determine the scientific reasoning ability evaluation standard,through the test before class preparation,issuing scientific reasoning ability,to study the status quo of scientific reasoning ability of internship class students.Second,according to the previous observations,classroom teaching aims to cultivate the students’scientific reasoning ability teaching strategy,combined with figure,min the demonstration of the basic elements and problem solving teaching model of basic requirements,build up the problem solving teaching model based on scientific reasoning,causes the student to obtain scientific knowledge at the same time in order to achieve the purpose of develop the students’ ability of scientific reasoning,In addition,two teaching contents of the 2019 Edition of Human Education Edition,the Effect of Magnetic Field on Moving Charge and the Movement of Charged Particles in uniform Magnetic Field,were selected to develop teaching cases and carry out teaching practice activities.Thirdly,the after-class test questions of scientific demonstration ability were issued.By analyzing and comparing the test results of the two groups before and after class,the effect of scientific argumentation-based problem-solving teaching model and teaching strategy on improving students’scientific demonstration ability was verified.Finally,a brief summary of the research is made,the deficiencies in the research process are elaborated,and the research content is prospected. |
