Study On The Validity Of High School Chemistry Driving Problems

Developing the core accomplishment of chemistry subject has been emphasized by the new curriculum.The creation of valuable problems should be paid attention to by teachers in class to promote the formation and implementation of students' core quality of chemistry.Subsequently,the driving problem teaching has become a hot issue and has been keened by teachers.The existing researches on the driving problems are mainly about the design of the problem,and there is no appropriate standard to judge whether the driving problem teaching is really effective.Therefore,the effectiveness of the high school chemistry driving problems is taken as the research object,and is carried out systematically.The paper summarizes the research results of driving problems at home and abroad by consulting the literature.The concept and connotation of "problem solving","driving problems" and "effectiveness of driving problems" are defined by the existing research and the author's viewpoint,and then the effectiveness standard of driving problems is put forward.In the aspect of current situation investigation,firstly,the present situation of chemistry driving problems teaching in high school have been investigated and analyzed by means of questionnaire survey.Then through the method of classroom observation,it is found that there are some problems in chemistry driving problems teaching in high school.More problems are caused by teachers to drive students' mind excessively;they are only used for course introduction and are raised by teachers in one single way.Meanwhile the causes of the problem are explained.Finally,aiming at these problems,the paper puts forward the solutions strategy and scheme.Through the research,the author concludes:First,although teachers pay attention to the way of driving problem teaching,but in the real implementation link,the driving of the problem can not effectively drive the divergence of students' thinking,and the problem can not be solved smoothly.Second,when teachers use questions to drive students,traditional teaching mode should be combined with driving problem teaching to achieve effective teaching and promote the formation of students' chemistry core accomplishment.Third,the effective standard of driving problem is an objective concept,and the standard also needs to be tested by concrete and real teaching practice.
