Research On The Effectiveness Of Chemistry Experiment Class Teaching In Rural Middle School

Chemistry is a natural science based on experiment, and chemical experiment promotes the formation of chemistry subject and accelerates the development of chemistry subject; chemical experiment is an important expression formof scientific inquiry and it is also the important form and method during the process of scientific inquiry. The efficient chemistry learning cannot be separated from the experiment, the efficient chem istry teaching of the teacher cannot be separated from the chemical experiment, and the chemical experiment is an important component of theefficient chemistry teaching. For this reason, the effective experimental teaching could not only improve the efficiency of the teaching, but it is also a good opportunity for cultivating the abilities of cognition, finding problems, solving problems, exploration and innovation, meanwhile it can help cultivate good value system, correct scientific experience and cognition for the students.However, during the experimental teaching, especially during the teaching process of chemical experiment in rural middle school, due to the environmental restriction, the teacher preparation, the special psychological characteristics of students in rural areas and other factors, there are some inefficient or invalid experiments unmatched with the new curriculum concept in teaching, and it leads to the result that the students reduce their interest in learning chemistry and the construction of efficient classroom is seriously restricted. According to the above conditions, I take the senior high schools in Suibin County as the example, investigate and analyze relevant issues restricting the effectiveness of chemical experimental classroom for two middle schools, and explore and study the method to improve the effectiveness of chemical experimental teaching for rural middle schools to some extent.this paper is divided into the following several parts; The first part is the introduction, and it mainly states thebackground, purpose and meaning of the research, domestic and overseas related research progress and the research method of this paper; the second part is the basic study; the third part is the statistics and data analysis of thequestionnaires for the teachers and students; the fourth part is the case and case analysis; the fifth part explains themethod to improve the effectiveness of ch- emical experimental classroom in rural middle schools through optimizingthe teaching facilities, optimizing the students’ cognition, optimizing the experimental mode and oth ercorresponding measures.
