Investigation On The Current Situation Of High School Students' In Dynamic Problem Solving

Dynamic is based on Newton's laws of motion, research the relationship between the motion and the force theory. To understand the current situation of high school students' in dynamic problem solving to teacher's effective teaching and student's result is of great significance. Therefore, based on the current situation of high school students' in dynamic problem solving, explore the causes of students' difficulties of solve such problem, and put forward some teaching suggestions.First of all, through the literature, this study for defining the relevant concepts, determine the constructivism theory, information processing theory and "trial-and-error" and "enlightenment" as the research of the theoretical basis. Second, interview part of high school physics teacher, in the teacher's point of view to understand the current situation of high school students' in dynamic problem solving. And part of longnan city in ordinary high school student to carry on the questionnaire survey, using SPSS statistics software, to individual student to carry on the open questions in the test and interview. Analysis of survey data, the research shows that the students the difficult to solve the problem of such main matching analysis stage, in the process of problem solving is due to the lack of accurate analysis of the question, students couldn't make the related process of stress analysis, sports figure, unable to establish the appropriate physical model, lack of Newton's laws of motion of the guide and the problem solving experience, the method cannot effectively caused by migration; In addition, when the problem representation can't catch the key words and solution implementation specification to express meaning, combined with the related laws of physics and mathematics knowledge of weak ability of students to solve such problems are also difficult; Not the difficulties and mistakes in the process of problem solving test, reflection, summarizes the students difficult test reflection stage. Students' habits of problem solving and teachers' teaching methods is the main cause of the difficulties.Finally, this study proposed accurately grasp the basic knowledge and concepts; Cultivate the students' science problem solving habit; Training students' confidence in the process of problem solving three suggestions. Strengthen basic knowledge and the concept of law accurately and subdivided into typical example selection, let the students the concept of law from the perceptual knowledge ascend to theoretical knowledge. Guide students to scientific thought, making reasonable and seize the concept, law master the main point. Cultivate the students' science problem solving habits including train the student to the physical situation analysis effectively, strengthen the training of the students for effective transfer of knowledge and improve students' ability to analyze the question when the physical situation visualization, the combination of improving students' mathematical ability, developing students' consciousness of reflection summary of problem solving and cultivate students' scientific and standardized problem-solving habits six parts.
